In today’s world, there has been intense struggle for water resources. This is due to rising population currently standing at 7 billion, their usage of water and extreme competition over water resources, water dependent crops and urbanization. Therefore, it is no surprise that the world is running out of fresh water every day. The need for water will continue to rise unless there are steps to conserve and recycle this crucial element. As of 2020, about 1.5 billion people are dealing with water scarcity due to climate change, drought, increasing population, poor management of water and increasing agricultural output under multiple stressors. This figure is said to increase to around 3 billion by 2025. Currently, the increasing population shows huge demand and competition over water resources in terms of household, commercial, and district uses which has been a massive contributing factor towards water scarcity.
As an outsider, Zanzibar looks like a wonderous cluster of coral islands off the east African coast. The island has white sandy beaches alongside the ocean blue water and a total of about 1.7 million population that survive on a mere £10 a week. This fast-growing population is faced by water shortage especially in areas like the Michamvi village and other small towns. Despite making multiple efforts to address the water issue, the Zanzibar islands heavily depend on the groundwater for domestic and commercial uses of water for their agriculture. The climate change and rising sea level largely affect the quality and quantity of water on the island which reflects the sensitivity of Zanzibar to such variability.
The Impact of Water Crisis in Zanzibar
The coastal island of Zanzibar off the mainland of Tanzania is faced with many challenges such as the high demands for agriculture, poverty, poor technological infrastructure, and availability of water resources particularly in the rural areas where clean and hygienic consumption of water remains difficult to achieve. This water scarcity largely affects women and children who end up walking for miles to obtain the vital source which is quite time consuming as it deprives the children of their education.
Zanzibar, like many other developing areas has obtained international aid for the establishment of wells, power cables, manufacturing desalinization systems, infrastructure and constructing sanitation systems in order to prove beneficial for the island. Unfortunately, despite huge foreign aid investments, the island failed to sustain these systems due to lack of education, resources and training resulting in only short-term benefits. To address this issue, an organization called Zanzibar Water Authority (ZAWA) was established which initiated Urban Water Supply and Sanitation project aimed towards enhancing the water supply mechanism and reconstructing the financial control of the distribution of water. ZAWA installed pay-stations for the citizens to pay off their water bills, but such system asked for a cultural change. If such change is adapted by locals, the future of this system seems fruitful but all-round accessibility to hygienic and safe consumption of water still remains a challenge in Zanzibar.
Addressing the Water Quality Issue
Access to clean and safe drinking water remains a huge challenge in Zanzibar as it is one of the driest areas around the world. Because of the rise in sea levels, the underground water is growing saline and getting polluted due to increase in germs and wastewater. For this purpose, three German organizations joined together in 2015 to provide access to clean drinking water to public on the island. These companies are supported by GIZ (the Deutsche Gesellschaft für Internationale Zusammenarbeit) working on the behalf of the government of Germany. Due to their efforts, about 2000 locals in the areas of Kijito Upele and Michamvi have gained access to affordable and hygienic consumption of water. Moreover, this new system also enabled the local services to keep a constant check on the quality of water within Zanzibar.
Challenges of Water Security and Climate Change in the Coastal Communities of Zanzibar
Similar to other small islands in the region, utilization and proper use of water sources are fundamental towards the elimination of poverty and food shortage in Zanzibar. Water management is also important in order to execute the Sustainable Development Goals 2030 set by United Nations especially the First SDG of “No Poverty”, Second on “Zero Hunger”, and sixth on “Clean Water and Sanitation for all”. This is due to the fact that this vital resource may reduce food shortage in local areas, decrease poverty, and enhance agricultural output. Even though Zanzibar has made multiple attempts in upgrading the water supply particularly in the domestic level in the past 10 years, in some villages around the coast, the availability and accessibility to water sources remain out of reach. Therefore, addressing the water security issue is important for the welfare and survival of human beings. Furthermore, people living in these areas rely on well and water from caves which are vulnerable to contamination and climate change.
The factors that depend on climate and local sources of wells and caves include household needs, livestock keeping, and crop farming as it largely depends on rainfall. It is also understood that water supply is not consistent but instant variable around these islands which allow the locals to experience water insecurity both in domestic and commercial level. Ultimately, those with less access to local water sources are more prone to water insecurity. Apart from arduous access to water supply, the communities also face other challenges including poverty and hydrogeology which contribute to water insecurity. Despite making efforts to improve water quality and quantity in Zanzibar, there is also potential for collecting rainwater to address the water issues. This harvest would not only improve water security in domestic level but also support the communities that are prone to climate change and depend on local sources in Zanzibar.
Access to Clean Drinking Water by Rotarians Despite Pandemic
The Zanzibar Island is said to have rich and freshwater aquifers which constantly face challenges including environmental sustainability, lack of water management and tourism. Even though Zanzibar experiences a huge number of tourists entering these islands, only 2.5% of the total population i.e. 30,000 of the people are employed. These tourists take up ten times more water usage than the local residents and few of the hotels dispose of their sewage into the sea which forms a thin line of soil over the coral areas.
The tiny settlements on the island acquire water through wells which are getting more and more polluted due to tourists, rise in population, and insufficient sewage treatment. Zanzibar Rotary in partnership with the Rotary club of Oadby Launde, a project formed in Leicester, United Kingdom, financed £1,000 and raised further £500 for the project Kiss Solar Energy to provide clean and safe drinking water in Mpadeni village. Despite the delay in project due to COVID-19, a sample was taken from the well dug about 20 meters deep in the Mpadeni village in October 2020. After being tested by ZAWA, it was passed as good quality of water.

Since centuries ago, climate change has been a matter of grave concern globally. It is also one of the substantial global challenge in the 21st century. Many scientists and local people, through contemporary and indigenous practices respectively, have diverse views pertinent to the meaning, source, and impacts of climate change. In terms of the meaning, it is scientifically agreed that, climate change is a long process at which the components of climate systemvary for many years.
Climate change is further defined by the Intergovernmental Panel for Climate Change (IPCC) as a statistically significant variation that persists for an extended period, typically decades or longer. It includes shifts in the frequency and magnitude of sporadic weather events, as well as slow continuous rise in global mean surface temperature.
Historical Background of Climate Change;
Climate change began in the early of 19th century when the ice age and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In late 19th century scientist first urged that human emission of greenhouse effect could change the climate, also many other theories of climate changes were advanced involving, forces from volcanism and solar variation. In 1960 the warming effect of carbon dioxide become increasing. Some scientists also pointed out that human activities that generate atmospheric aerosols example pollution could have cooling effect as all. During the 1970s scientific opinions increasingly favored the warming effect. By 1990s, as result of improving observation work and confirming the Milankovitch theory of ice age consensus position formed greenhouse gases were deeply involved in most climate change and human cause emission are causing global warming
Moreover, there are some scientists who urged on the urgency on climate change, starting by Joseph Fourier (1768-1830) who started talking about something called the greenhouse effect. He knew that the atmosphere protects us from the sun, and he suggested that the composition of atmosphere will change and could lead to the warming of the earth. A few decades later in 1861 another scientist known as John Tyndall(1820-1893), identified the gases that may cause such effects when he was investigated the absorption of infrared radiation in the different gases, he found that water vapour and hydrocarbons like methane and carbon dioxide, strongly block the radiation and lead to cause the warming in the earth. Other scientist like James and peter kropotkin suggested that ice ages and other climate change were due to change in number of gases emitted in volcanism but was only one of possible causes. Another possibility was solar variation and shifts in ocean current which identified by them. (Croll, 1875)
According to the reportof United Nations Framework Convention on Climate Change (UNFCCC) that gathered at Copenhagen in December 2009 to try to reach agreement on global action to combat climate change for the period until the 2012 successor to the Kyoto Protocol that will come from Africa. Based on what is Africa’s interest in this global effort to meet key climate change objectives? how will Africa perform in Copenhagen? will Africa make a difference to the outcomes of the negotiations and the Copenhagen Agreement, given its passive role in Kyoto?
Most analyses of the impacts of climate change that have influenced UNFCCC agreements focuses on medium to long-term projections of carbon emissions and forecasting models of global warming, and cover mainly countries and regions for which relevant data are readily available. This leaves out most developing countries and regions, particularly Africa, due to unavailable data and trajectories. From an African perspective, this is serious and costly. As the poorest continent, Africa is considered most susceptible to climate change due to its vulnerability and inability to cope with the physical, human, and socioeconomic consequences of climate extremes.
Moreover, existing adaptation mechanisms and resources under the Kyoto agreement designed to mitigate climate change’s effects on Africa and other developing regions have been directed at limiting future carbon emissions, rather than addressing the region’s vulnerability and lack of resilience to the impacts of climate change on its economies and populations. As lof ate as April 2007, a report by the Intergovernmental Panel on Climate Change (IPCC) warned that Africa was not acting quickly enough to stem the direct economic and environmental consequences of greenhouse gas emissions (IPCC, 2007). What this report seemed to have missed or overlooked is that Africa’s concern about climate change is not mainly in terms projections of carbon emission and future environmental damages. It is more about the links between climate change and droughts, desertification, floods, coastal storms, soil erosion contemporary disaster events that threaten lives and livelihoods, and hinder the continent’s economic growth and social progress. (Solomon & Qln, 2007)
Causes of Climate Change
There have been diverse views about the origin of climate change. The debate on the origin covers two major aspects.
First, tells that climate change has been in place for millions, thousands, hundreds and tens of years ago (decades). The proponents of this notion mention the disappearance of flora and fauna species like the dinosaurs which were extinct not because of human, rather due to variations in temperature and rainfalls. They further connect their views with mass extinctions which occurred millions of years ago. Previous studies have presented the first dimension which assert that, climate change is due to natural forces. They associate earth’s orbital variations, Sun rise and set, volcanism etc. as natural events which in turn cause unusual weather patterns out of human control Furthermore, their arguments maintain that, natural forces like land masses drifting, plate tectonics, earthquakes, volcanism etc. fueled climate change.
The second perspective urges that, climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect first identified. This notion went far to link that, human activities has been the cause of climate change as they rightly observed the industrial revolutions notably mounted from19th with immense greenhouse gases emissions. They associate Human activities like industrial activities, agricultural activities, mining transportation, and others cause emissions of gases hence lead to drought, floods, etc. not only that but also God’s punishment due to unrepentant human sins, and disobeying fore ancestor’s cultural setups is believed as the cause of climate change to same of the believers.
In Tanzania also there are various human activities which contribute to the emission of greenhouse gases hence influences climate changes. activities like industrial activities, agriculture activities, deforestations, mining activities and burning of fuels are among of the human causes of climate change.
Trigger’s force of climate change and its impacts
IMPACTS OF CLIMATE CHANGE IN TANZANIA
Over the centuries and decades, climate change has been perceived as a double sword in terms of its impacts to sectors of economy, living, and non-living worlds.
Climate change projection indicates that the frequency and severity of extreme climatic events will increase. In the last 40 years Tanzania has experienced severe and recurring droughts with devastating effects to agricultural, water and energy sectors. Currently more than 70% of all-natural disasters in Tanzania are hydro-meteorological, and are linked to droughts and ﬂoods. Climate change Impacts various sectors in Tanzania as follows
Agriculture and Food Security
Changing climate has resulted in a general decline in agricultural productivity, including changes in Agro-diversity. The prevalence of crop pest and diseases is also reported to have increased, posing more challenge to agriculture. Furthermore, due to the change in weather patterns that have disturb the agricultural production has impacted food security.
Adverse impact of climate change in agriculture activities
Fresh Water Resources
Increasing rainfall variability and prolonged droughts cause serious pressure in the country’s available water resources. Severe and recurrent droughts in the past few years triggered a decrease in water ﬂows in rivers, hence shrinkage of receiving lakes, declines of water levels in satellite lakes and hydropower dams. Furthermore, some of the perennial rivers have changed to seasonal rivers and some wetlands have dried up.
Variability in precipitation may have direct consequences in infectious disease outbreaks. Increased precipitation may increase the presence of disease vectors by expanding the size of existent larval habitat and creating new breeding grounds. In addition, increased precipitation may support growth in food supplies, which in turn support a greater population of vertebrate reservoirs. Alternatively, ﬂooding may force insect or rodent vectors into houses and increase the likelihood of vector-human contact. IPCC, 2001 indicates that many vector, food and water-borne diseases are sensitive to changes in climatic conditions.
There are also a wider set of indirect impacts from climate change on health, which are linked to other sectors such as food security and malnutrition through reduced agricultural productivity as a result of changes in soil quality, increased crop and livestock pests and diseases, prolonged drought and water scarcity. Reduced agricultural productivity associated with climate change/variability exposes communities to other health risk factors, such as HIV or AIDS.

Coastal and Marine Environment
Major climate change related impacts are a result of increases in sea surface temperatures and associated sea level rise. Some of the impacts are destruction of coral reefs, coastal erosion, submergence of small islands, destruction of coastal infrastructures and human settlement, intrusion of sea water into freshwater wells, and degradation of mangrove.
As a result of increasing climate variability, over the last years, the country has experienced increasing incidents of recurrent and prolonged droughts with severe implications on hydro power generation. Power rationing and black outs have become a common phenomenon in Tanzania. This affects individuals’ household and industrial income generating activities. Consequently, additional resources which were committed for other development programs are sometimes being reallocated for thermal electricity generation
The common impacts to all forest’s types include loss of biodiversity; disappearance of wildlife habitats, increased risk of bush ﬁres, limited availability of forest products (timber and non-timber products) and ecosystem shift
Overall, a very high possibility of irreversible losses of biodiversity as a result of such changes in climate are projected with many terrestrial, freshwater, and marine species being placed at a much greater risk of extinction than before. Water shortage for the large mammals especially in the years with low rainfall is one of the main challenges facing the wildlife. The places that naturally used to hold water during the dry season no longer hold water long into the dry season. For instance, water dependent animals especially hippopotamus, crocodiles, buffalos and elephants are often found crowded in few remaining water ponds, for example in the Ruaha and Katuma River system
Hippopotamus congregation in small water pools due to water shortage in Katavi River system in 2009
Tourism has close connections to the environment and is considered to be a highly climate sensitive sector. Climate variability determines the length and quality of tourism seasons thus plays a major role in the destination choice and tourist spending. Climate also has an important inﬂuence on environmental conditions that can deter tourists, including infectious disease, wild fires, insects or waterborne pests, and extreme events such as tropical cyclones. the sector is already being impacted by climate change. The manifestations of climate change are highly relevant for tourism destinations and tourists alike. For instance, Mountain Kilimanjaro has lost 80% of its ice cover between 1912 and 2000
Apart from the impacts of sea level rise, which have destroyed cultural, historical, archaeological and heritage sites along coastal areas in the country, heat stress and drought have also caused massive wildlife deaths in the northern tourist zone. Destruction of infrastructure such as roads and bridges are devastating. Road maintenance becomes particularly difﬁcult and expensive during prolonged heavy rains in many parts of the country. For example, the 2006 El Niño rains, left many park roads impassable for a long period of time, and resulted in reduced tourist visits and loss of revenue
Decrease ice coverage at Mount Kilimanjaro as the effect of climate change
Furthermore, climate change has impact on livestock sector, industrial sector, fishing sector infrastructures and transport sector, human settlement, land use and planning and education sector of which these sectors are important for development, employment opportunities and back born of the economy.
CLIMATE CHANGE INITIATIVES IN TANZANIA
In addressing climate change at national level, and local levels various initiatives and programs have been undertaken in Tanzania in the context of UNFCCC and its Kyoto Protocol. implementation of the UNFCCC and the Kyoto Protocol is further supported by the enabling environment including the National Environment Policy (1997) and the EMA. Not only that but also private sectors and private organizations has played an advantageous part in addressing climate change in Tanzania. Furthermore, climate change adaptation strategy and climate change related programs in the country including REDD and REDD+ projects are among of the initiates towards climate change mitigation, adaptation and coping strategies.
MITIGATION, ADAPTATION AND COPING MEASURES TO CLIMATE CHANGE IN TANZANIA
It is evident that, climate change is happening and will continue to ravage sectors and our livelihoods. Various studies have revealed that, people from different areas have been mitigating, adapting and/or cope with it in order to make lives goes on. In Tanzania also communities mitigate, adopt and cope with climate in various ways through in small extent due to poor awareness on climate change and normally the following are some of the measures taken and suggested for mitigating, adaptation and coping with climate change
Mitigation measures to climate change
Mitigation involves the efforts undertaken to reduce anthropogenic (greenhouse gases) emissions or to enhance natural sinks of greenhouse gases so as to reduce the threats of climate change (to lower the risks). Mitigation measures suggested and taken in Tanzania are like:
Building water reservoirs like dams, ponds etc.
Use of environmentally friendly energy sources like geothermal, natural gas, solar, and wind energy than charcoal, coal and fuelwoods.
Use of organic manure which prevent nutrient and water loss.
Soil as the biggest carbon sink on the planet, sequestrate greenhouse gases by proper soil conservation methods like contour planting and no-till farming which do not disturb the soil.
In reducing methane, farmers may prevent submergence of rice fields and cultivate uplands rice or other upland crops.
Adaptation to climate change involves the process of adjustment to actual or expected climate and its effects, in order to moderate harm or exploit beneficial opportunities. In Tanzania adaptation measures undertaken and suggested are like:
Farmers planting different crops for different seasons
Levees against sea level rise
Temporary and permanent migration
Building water reservoirs
Re-use, recycle and Reduction of the use for resources like water
Rain water harvesting and retention
Changing the planting seasons
Use less greenhouse gases sources of energy
Growing early matured crops
Rearing drought resistant livestock.
Formulation of social climate resilient groups venturing in rural savings, table banking schemes, getting funding from innovations funds and micro-financing institutions.
Establishment of community-based climate change adaptation Organizations
Establishing climate early warning systems
Farming intensification and extensification
Mulching to conserve moisture during droughts.
Chemical weed control
Switching to off-farm activities
However, once we go deep to explore the adaptation measures, one has to find out that there are measures which take a long time to adapt and others take a short time. In this context, those measures that take a short time are referred to as coping mechanisms, as they may not demand adjustments to ecological, social, or economic systems in response to actual or expected climatic stimuli and their effects or impacts. Therefore, the coping strategies practiced in Tanzania and those suggested are like:
Receiving remittances from children/ relatives living in urban
Borrowing cash to buy food
Reduce the number of meals per day
Renting land for cash
LIMITATIONS TO CLIMATE CHANGE MITIGATION, ADAPTATION, AND COPING STRATEGIES IN TANZANIA
Lack of mitigation and adaptation technologies
Little awareness and researches on climate change
Lack of information on climate change impacts
Lack of access to early warnings and unreliable of seasonal forecast.
High cost of adaptation
Inadequate farm inputs
Weak institutional coordination and support
Low institutional capacity
Poor extension services
Poor enforcement and implementation of laws and by-laws
Too much bureaucracy
Conflicts between farmers and pastoralists
Satisfied that climate change is the will of God
Reluctant to take changes
Generally, most of disasters in Tanzania are related with the climate change impacts there fore mitigating, adopting and coping with climate change links with disaster risks reduction and management activities. And regarding various climate change related impacts Climate change is indeed real and evident, it is inevitable, and it has to be appropriately and sustainably addressed.
1. UNEP and UNDP 2016-2021 environmental and development strategy
Through a country programme, UNEP (United Nation Environmental program) and UNDP (United Nation Development program) proposed a strategy to counteract climate change issues while improving the Tanzanian economic development. Based on a theory of change where better governance and better placed investment could decrease poverty as well as environmental degradation. In the same way, the goal is to enhance the participation in economic, environmental, and governmental issues of women, youth, and disabled individuals. To anchor sustainable development, UNEP wants to implement sustainable interactions with all institutions such as both private and public partners. In partnership with those institutions as well as the government, UNEP will be able to achieve sustainable development projects. Those projects will mainly focus on environment, natural resources, climate change governance, energy access and disaster risk management.
The forestry sector is leveraged with the agriculture of the Tanzanian developmental economy representing 90% of the country’s energy resources and ½ of his supplies in construction materials. Because of the high dependency on agriculture and the rapid population growth, pressure on the environment and natural resources have largely increased in the last few years. Deforestation, it’s becoming one of Tanzania’s major challenges.
UNEP is taking action to improve institutional and regulatory frameworks for safeguarding protected areas and preserving biodiversity. To fight against deforestation and deteriorating environmental quality, the institution is focusing on many interventions:
mainstreaming environmental concerns into development plans
Facilitating environmental laws and regulations
Scaling up community-based environmental protections initiatives
As well, to protect natural resources and avoid ecosystem degradation, UNEP actively works on:
Improving conservation of forest biodiversity, ecosystems
support efforts to combat poaching and illegal wildlife trade
Scaling up sustainable land management practices
Supporting community based-forest management initiatives
Promoting conservation agriculture
Finally, UNEP is highly supporting and promoting the REDD+ program. This program creates a financial value for the carbon stored in forests, by offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. Developing countries would receive results-based payments for result-based actions. REDD+ goes beyond simply deforestation and forest degradation and includes the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks.
According to the UNEP, the Tanzanian land faces many challenges because of its fast development expansion and its demographic growth. Those challenges are the following:
unplanned human settlements
encroachment into forest areas
inappropriate farming and livestock management practices
unregulated mining activities
poor inter-sectoral cooperation
weak stakeholder linkages
poorly planned and uncoordinated action
To fight against those challenges, UNEP and UNDP (United nation development program) will take example in the Sustainable land management (SLM) program implemented in other
Countries that have been successful. The lack of financial resources and adequate capacity in Tanzania remains a key barrier to this program. Both institutions will mainly focus on building institutional capacity and strengthening coordination between stakeholders, implementing practical SLM interventions to land degradation in forest, rangelands and arable land. Finally, they will promote watershed (hydraulic pool) management interventions to show environmental challenges to the Tanzanian community.
As a result of climate change manifestation, Tanzania will face a rise in extreme events as droughts, floods, the rise of sea level, dwindling water sources as well as impacts in the agricultural sector, energy sector and health sector. UNDP’s plan proposed support by promoting the implementation of sustainable strategies through high-capacity building initiatives and the establishment of proper institutional, policy and financial frameworks in collaboration with all key stakeholders, including the private sector. At the local level, implementing small scale climate change adaptation projects to create livelihood opportunities particularly in the agricultural sector as population depends on rain-fed agriculture as a source of livelihoods, income, and consumption.
For example, promote and help the IITA (international Institute of Tropical Agriculture) in their work with farmers to get agricultural expertise’s. Debate sessions are organized to discuss essential topics such as “What crop can I grow with this irregular rainfall season?”. The final goal is to help those farmers to have sustainable agriculture.
Moreover, UNDP wants to focus mainly on the implementation of COP21 Paris Agreement outcomes, under the United Nation Framework on climate Change. They will focus on supporting the government in order to create a framework for the implementation of INDC’S (Intended National Determined Contribution) which will be leading to greenhouse gas emissions reduction.
To tackle the development of the fossil industry and transit to sustainable energy, UNDP implemented the SE4ALL (Sustainable energy for all) program to be achieved by 2030 in Tanzania. This program focuses on three targets:
Ensuring universal access to modern energy
Doubling the rate of improvement in energy efficiency
Doubling the share of renewable energy in global energy mix
The institution was able to mobilize significant political support before RIO+20 and continued to provide coordination and technical assistance around those three targets.
Thanks to UNDP, sustainable energy access for all in Tanzania is moving fast. By coordinating the implementation of the SE4ALL initiative, an Action Agenda and an investment prospectus has been created. It brings poorer communities appropriate, reliable, and affordable energy technologies. This can be possible mainly by improving policy and regulatory framework, improving institutional framework and human capacity, strengthening the M&E (Monitoring and evaluation) framework as well as generate relevant data.
Resilience is the ability of the system, community, and society to resist, to accommodate against hazards. Over 70% of all-natural disasters are hydro-meteorological and the major disasters have included droughts, floods, and epidemic diseases. All of them, affecting humans and wildlife.
As an example, let’s take the “El Niño phenomenon” that occurred in Tanzania in 2011. It causes massive floods which wash away crop farms and damage transport infrastructure, such as roads and railways. As well as destroying houses making people homeless. It also increased diseases. We’ve seen the impact of an RCP 8.5 scenario; phenomenon’s like “El Niño ” will occur increasingly frequently.
As a response, UNDP’s proposal is to strengthen the institutional framework of meteorological institutions, including the establishment of a 24/7 Emergency center for climatic disaster management. Improve weather and climate forecasting infrastructure throughout the procurement of the installation of highly sophisticated hydro-met technologies to improve collection of the hydro-met data.
Also, they want to improve analysis, interpretation, and customization of data in order to provide relevant information to groups including farmers, urban and rural dwellers, and aviation. Finally, the development of Standard Operating Procedures (SOP’s) to improve coordination in dealing with disasters between the relevant institutions.
2. Climate Action Network International implication for Tanzania
Moreover, other than the United Nations institutions, other NGOs stand out for their innovative projects and their response to the global warming threat. It’s the case of Climate Action Network (CAN) International, very active in Tanzania.
Þ Climate Action Network Annual Strategy Session 2020 in Arusha
In February 2020, CAN organized the Annual strategy session about Climate change in Arusha. This event, which brought together several major climate actors, was an opportunity to discuss two major topics: “What does it mean for society/funders to build power in this climate emergency?” and “What are they doing to respond to the crisis and what do they believe is CAN’S role?”.
Through many debates and workshops all these actors agreed on the priority areas where investment is needed in terms of funding, human energy, and collaborative strength. Centering climate impacts and people to ensure governments act with urgency as well as exposing and undermining the fossil fuel industry, are the two priorities CAN and other NGOs should focus on.
Major events are going to take place in the next five years depending on the pandemic situation. These gatherings involving actors from all over the world (government, NGOs, the private and public sector industry) will be an opportunity to put these two issues on the table on a larger scale in order to take urgent action for our planet.
In the meantime, while awaiting those gatherings, CAN already started its fight for the climate by working on diverse projects and implementing solutions for the Tanzanian community. Here is the major one’s:
Water Purification & Biogas Plant (TAHUDE Foundation) is an initiative to build low carbon and resilient communities by providing access to clean drinking water and energy.
Climate-Smart Agriculture (ACT) is a community-led action agricultural initiative, which provides training to farmers on climate smart agriculture techniques such
as water conservation (bases/pots technique), short harvesting period, intercropping and mulching materials.
Climate-Smart Coffee Farming by Solidaridad is also a community-led initiative which provides training to coffee farmers on climate-smart coffee farming practices such as developing pest resistant methods, water harvesting/ conservation, short harvesting cycle crops, nursery practices, intercropping and shade coffee management.
Water for Livestock (Oikos) is part of the ECOBOMA initiative which is a project to build the adaptive capacity of the vulnerable Tanzanian community to cope with the adverse effects of climate change and reduce poverty in rural areas.
Tree Planting & Forest Conservation (Arumeru District Government)
Media Training Bootcamp: a practical skills session to build the capacity and strengthen the member’s ability to be spokespersons and to deliver powerful messages for press conferences and interviews.
Leadership & Diversity and Building a Grassroots-Driven Network Bootcamp: the objective of this session is to build members’ knowledge and understanding of how to link policies with people and navigate power and privilege to facilitate diverse inclusion and create safe, engaging spaces for grassroots leadership and organizing across CAN.
Developing Funding Proposals Bootcamp: the purpose of this session is to provide members with concrete ideas and shared thinking on good and effective fundraising. The bootcamp facilitated discussions on key elements of fundraising,
a good elevator pitch and how to approach funders and keep the communication lines open.
Fossil Fuels Non-Proliferation Treaty Bootcamp: this session provided members with a background and overview of the Non-proliferation Treaty for Fossil Fuels Initiative. This initiative uses the experience and outcomes of the Non-proliferation Treaty on Nuclear as a basis and is trying to adapt this to dealing with fossil fuels. The session explored a set of high leverage strategies that this initiative could galvanize around such as the phase-out of fossil fuels and shifting narratives on fossil fuels, strengthening local action to stand against fossil fuel expansion, and encourage international cooperation to stop fossil fuel proliferation through a Fossil Fuel Non-Proliferation Treaty.
After the announcement of all these projects, we can better understand the involvement and dedication of the institution to change the habits of the Tanzanian community to provide them with a more promising future than RCP 8.5. However, there is one last project that particularly caught my attention, and which demonstrates the long-term impact vision that the institution is trying to establish. This CAN project is the climate and livelihood center in Bagamoyo. The purpose of this green village is to link scientists to the communities to provide new initiatives. Many activities are organized going from cultural events to environmental workshops. Everybody is welcome regardless of their work sector (fisherman’s, students, small-scales farmers, etc.). The center provides knowledge through training and teaching, the possibility to implement the improvements directly on the site and most of it, the center tried to provide this networking to have a bigger impact and reach more communities and partnerships.
They organized three workshops in December 2019 to raise awareness and inform the participants on renewable energies (RE) and the necessity of transitioning to clean and affordable energy. 124 participants were representatives of women groups, local government authorities, and civil society organizations.
Because the baseline study was focused on their own villages, people were highly interested. The survey showed that 92% of the households were not capable of paying the highly initial cost of renewable energy. But the community saving groups might present an opportunity for decentralized energy. 42% were unaware of the potential of RE, only solar was common and most of them (91% of the survey) use charcoal and firewood for cooking
Because of deforestation, people have difficulties using firewood (takes three hours to collect) and their only alternative is charcoal. Many of the village’s council stated that they did not include RE into their agenda due to the lack of understanding and support from government and non-governmental stakeholders.
Participants were really curious and interested about identifying achievable and long-term solutions. With the help of CAN in Tanzania, they establish and initiate RE clubs in primary and secondary schools that allow children to be innovative and creative. Finally, those workshops promote awareness about RE. Shumina Rashidi, the councillor of the Bagamoyo District and a businesswoman, for example told the CAN team: “In the workshop I learnt that cooking with gas is very cost effective – especially because I am living in Bagamoyo town, where it is available everywhere. I am going to use gas for cooking – not only for my health, but also to protect the environment. “
The important point is to understand that these people have no idea of what climate change is, why we said that the globe is becoming warmer, and why we should care about fossil fuels. That’s why it’s essential to sensitize and inform them before taking actions or implementing projects where they don’t understand the environment purpose.
During our interview, Adelaide Mkwawa said “you know there is a huge friction between NGOs and the government. If NGOs tell the truth and the government disapproves, they can remove your NGO license”. NGOs have to be very careful and clever not to come into conflict with the lack of investment and impact of the government while at the same time making them understand the importance of acting quickly and strongly.
For Adelaide, who had also worked for the UNAT (United Nation international justice system), NGOs had implemented lots of projects in response to the SDGs. Most of them have being undertaken by the Parliament Group of sustainable development to enter those propositions and projects in the government budget. But at the moment, where those projects and propositions are in the hands of the government then it’s really hard to find their progress because of the lack of information and the lack of knowledge to communicate by the government. Communication between institutions is really poor due to lack of resources and the inordinate amount of time that elapses between the transmission of the first information and its evolution. For Adelaide, this is one of the biggest issues and that’s why projects in Tanzania take so much time. In her opinion, the creation of a communication sector that’s effective will facilitate this collaboration between the government and NGOs.
Investment for Climate change is all about communication and collaboration. Even for the private and public sector. A close collaboration between institutions on their new methods and techniques to afford sustainable development is a key point to move forward. Some institutions in Tanzania have excellent ideas to fight against this global warming while in the meantime ensuring the economic development of the country. This is the case of TWIGA CEMENT INDUSTRY.
4. Combining economic development and environmental responsibility: TWIGA CEMENT example
Tanzania Portland Cement Company Limited (TPCC) also called TWIGA Cement is a cement-manufacturing company. Member of the Heidelberg group and listed in the Dar es Salaam stock exchange, is the largest cement manufacturer and reports a company total asset of 322 billion TSH (141 million US$).
The challenge for TWIGA is colossal. On the one hand it is one of the biggest employers in the region, employing hundreds (more than 300 in 2019) of people. These jobs are quite simply indispensable for people’s survival from a human and community point of view. Moreover, it is one of the main reasons for the development of the region, where their cement has enabled the construction of many buildings and most of the houses. However, on the other hand, it is one of the biggest emitters of greenhouse gases and is at the origin of many environmental challenges, in particular its production: Soil erosion, soil health, topography, deforestation, pollution of waterways, health, and safety of workers and community.
We had the chance to visit it and we realized some important facts during this day. First, there is a military base in the company’s own premises which testify an economic state interest and a voluntary security to the factory. Second, most of the workers pass have also a Chinese translation which testify an economic interest from China.
The largest drivers of climate change are large corporations and industrial factories. Since TWIGA belongs to this category they are holding themselves responsible to reduce their negative impact on the environment. Despite all the prejudices I had on this type of company, I was quite surprised.
TWIGA Cement counters their negative action by giving to nature what they had stolen from her. About ten years ago they founded the Nursery project to tackle their environmental impact. In order to collect these precious stones for the creation of cement, TWIGA has to dig for hundreds of meters, destroying the surrounding nature. When the digging space is exhausted, they fill it with soil and sand and replant some fast-growing tree species on top. These trees allow the soil to be re-fertilized, thus restoring the basic natural conditions. Once the fertilization has been completed, the fast-growing wood is cut for consumption and various new species are then planted permanently. It’s at this point that the nursery project appears.
The goal of the nursery is to mitigate damage being done to the surrounding environment, improve the health and wellbeing of underserved groups in the community, such as school children and prisoners by providing free shade trees. The nursery improves air quality and the environment at large through carbon sequestration. In the nursery they have quite a lot of species going to the Averrhoa bilimbi (culinary interest and the leaves serve as a paste on itches, swelling, rheumatism, mumps, or skin eruption) to the moringa oleifera (Its young pods and leaves are used as vegetables. The seeds are also used to purify water, as a detergent, or as a medicinal plant.) and even mint.
A barren plot of land in close proximity to the cement production has been transformed into a lush haven for biodiverse plant species and crucial pollinator species. Many of the trees grown there have medicinal benefits or are fruit bearing. To achieve their goal TWIGA has undertaken this project and educates the community by engaging with volunteers and hosting students to teach them how to maintain gardens and plant trees. They are also introducing the concept of sustainability to many local youths and giving them the tools to raise their own trees in needed areas. They are spreading the culture of sustainability and changing the mindsets of the young generations.
However, there are still some challenges to achieve such the six volunteers in the nursery compared to the hundreds of people employed in the factory. Despite all the efforts made, we can still understand where the priority is.
TWIGA Cement could be a great example to follow for many drivers around Tanzania and even further. Everybody needs cement, unfortunately in Tanzania, wood is the main construction material and the transition for sustainable tools that avoid deforestation and greenhouse gases are not readily available today. The carbon sequestration provided by those hectares of nursery, permits TWIGA to achieve its goal of developing Dar es Salaam district while at the same time reducing its negative impact.
Investing in R&D (Research and Development) for green energy could be the next step for TWIGA cement to achieve their goal of being a zero-carbon emission company.
Because at the end, compared to developed countries such as European ones or the United States, African countries and especially Tanzania have only small responsibility in the global warming issue. Tanzanian people because of low incomes mostly consume daily needs. Most of them don’t travel out of their countries because plane tickets are too expensive, and their water consummation is ridiculously low compared to a country like Germany or France. When you drive through Tanzania you don’t see any herds with thousands of animals, in other words no intensive farming and all their agriculture is natural, i.e., without the use of pesticides. Still Tanzania and other African countries will be the most affected by climate changes in the next decades.
As I said, Tanzania is a small greenhouse gases emission driver. Nevertheless, if the major drivers of those greenhouse gases which are mainly fossils industries. Take the example of TWIGA Cement and how they invest in R&D for clean energy, Tanzania could become an example of sustainable development for all African countries.
Through my internship at the Art in Tanzania institution, I had the chance to participate in many debates classes whose aim was to learn English while debating on sensitive subjects such as religion, waste management or Covid 19. I was very surprised by the open-mindedness and the stance that Tanzanians can take on such subjects. Unlike our European countries where discussions often turn into a confrontation of two ideals rather than the understanding and acceptance of a difference. Therefore, after more than two months of living together and sharing their traditions, I am convinced that the Tanzanian community has a key role to play in their climate issue. The government and the various institutions that want to work towards a more responsible and sustainable economy can rely on the collective strength and openness to change of its people. Tanzania can become a pioneer in the development of a green and responsible economy. To do so, its community needs to be informed and heard. The government and institutions need to invest heavily in intelligent campaigns to raise awareness of the benefits of the environment and the importance of caring for it. As we have seen with the example of the workshops held in the Bagamoyo Knowledge Centre, the participants are more than interested in green energy as it can improve their daily lives, their economy, and their biodiversity. The Tanzanian community is willing to listen and act for the good of their country, if it will improve their life. The next generations have a major role in this awareness, and it is through the youth that these innovations will be born. Of course, nothing worth doing is easy and such a transition will not happen overnight.
Tanzania is a coastal country in East Africa which shares the Victoria Lake border with Kenya and Uganda. Given that the vast majority of the population’s livelihoods are dependent on the agriculture sector (80 % of the population) which is highly sensitive to climate change, Tanzania is considered to be particularly vulnerable to climate change. Climate change impacts are already taking a significant toll on the livelihoods and wellbeing of Tanzanians, including:
Rising of severe droughts frequency and its associated water scarcity issues, slow down in the food production chain, economics and poverty reductions gains, reduced quantity and quality of the water in Victoria Lake, including an increase in contaminants which impact the purity of the water and have the potential to harm health, reduced surface water flows and aquifer (see diagrams below) that recharge during drought periods, as well as groundwater depletion through aquifer over extraction.
Furthermore, we can anticipate the intrusion of saline into aquifers (diagram) in low-lying coastal areas, as well as on a more global scale, impacts from coastal flooding. Climate projections for Tanzania include increased periods of prolonged drought, more erratic rainfall patterns (leading to extreme flooding) and a rise of sea-levels, all of which may exacerbate the mentioned pressures on water resources in this already water stressed country. If Tanzania’s low capacity for climate resilience is not addressed, this will likely have a profound impact on public health, stifling future development in urban and rural settings alike.
In this section, I’m going to illustrate what transformation we can expect in different sectors in Tanzania such as energy, agriculture, water, and health.
Before going into technical information, it’s important to understand how those sectors will be impacted. In most of the diagrams, there will be two baselines: RCP 2.6 and RCP 8.5
The Representative Concentration Pathways (RCP) is a greenhouse gas concentration
(Not emission) trajectory adopted by the Intergovernmental Panel on Climate change (IPCC). They described different climate futures depending on the volume of GHG’s emitted in the years to come. Founded by the World Meteorological Organization (WMO) and the United Nations Environmental program (UNEP), IPCC’s role is to provide objective with scientific information to understand the risk of human induced climate change and drafted recommendations to act in consequence.
IPCC has foreseen many different scenarios such as RCP 1.9, RCP 2.6, RCP 3.4, RCP 4.5, RCP 6, RCP 7 and RCP 8.5. In the following analysis of Tanzania climate change future, we are going to focus only on RCP 2.6 and RCP 8.5.
RCP 2.6 requires that CO2 will start decreasing by 2020 and go to zero by 2100. Methane emissions (CH4) are going half the CH4 level of 2020 and Sulphur dioxide declined to approximately 10% of those of 1980-1990. In simple words we will be able to respect Paris Agreement and likely to keep global temperature warming rise under the 2*C by 2100. We will have to face new environmental conditions, that are still close to the actuals one’s, but our daily life will remain comfortable.
RCP 8.5 as you can imagine is another story. It’s the worst climate change scenario with a very high baseline emissions scenario. Experts see it as the “business as usual” scenario.
RCP 8.5 scenario assumes that by 2100 there will be between 9.6 billion and 12.3 billion people. Assuming that the collapse of fertility will occur in the entire world without considering Africa. For example, Nigeria’s population will rise from 175 million nowadays to 1.5 billion by 2100. Almost all the fossil energies will be consumed, and we can expect that southern Europe will be the new Sahara. Most of the people on the planet will be leaving in extreme conditions. A scenario where giving birth in 2100 would be condemning your children to a hopeless life.
As warmer air has a higher capacity to carry moisture in form of water vapor, future climate raises the likelihood of strong rainfall events, towards the extremes. In many
places around the world, the maximum expected amount of rainfall in a 10-year period is projected to increase, which can lead to flooding.
Nowadays, Tanzania is issued to this seasonal temperature and climate variation. Rainfall period starts in December and ends at the beginning of April. Then, the easter season arrives with comfortable temperatures, consequently causing the arrival of millions of tourists.
What would be the projection of this monthly precipitation in RCP 2.6 and 8.5 scenarios?
Compared to historical data, between 2080-2099, Tanzania will face variation around 75mm maximum (January, November) of its precipitation which will reinforce floods in coastal regions and in the Victoria Lake region. In other terms, the rainfall season will be each year more intense, but Tanzania will have time to adapt to those new conditions. New innovations will engender better management in the agricultural and the energy sectors. On the left, monthly precipitation projections for 2020-2039. On the right, monthly precipitation projections for 2080-2099. In the case of RCP 2.6 scenario, the difference in 50-80 years is not considerable.
In the case of RCP 8.5, monthly precipitation will drastically increase leading to a maximum precipitation level difference of around 150mm in January. On the left monthly precipitation projections for 2020-2039. On the right, monthly precipitation projections for 2080-2099. In the RCP 8.5 scenario.
In both cases, precipitation concentration will increase, which will intensify future floods, yet not with the same intensity. Indeed, in the diagram above, RCP 8.5 scenario demonstrates the impact of “business as usual” attitude towards Tanzanian climate. It is clear that if we were to find ourselves in the situation of the diagram on the right, business will not be as usual. Power production will be largely affected. For example, the transportation lines for fuel could be interrupted by local flood for days or even weeks, or the networks distribution could be disturbed by excessive rainfall and flooding. Agriculture will be hit critically with farm crops always swept by floods which will drive Tanzania into a deeper poverty.
Drought: extreme events
Both power demand and production are tied to water availability. Obviously, this is most directly the case in hydropower systems. Although, dry conditions might also come along with higher temperatures, thus heightened cooling needs and an increase in demand for water pumping, particularly in regions of intense agriculture.
On the production side, water is required for cooling the power plants. If there is not enough water, then cooling is restricted, thus production might need to be slowed down. In some places, there are regulations preventing power plants from causing an increase in the temperature of returned water above specific thresholds, which are dangerous for local fish and plants. These thresholds are more quickly reached if stream flows are low during dry conditions. In a few regions, too much moisture can also be an issue as water might need to be removed.
Concerning agriculture, drought can disrupt its demand and production because the exposition of soils to high temperatures and the scarcity of water can result in the infertility of soil.
In the RCP 2.6 scenario, temperature will rise for 2.5 degrees with extreme variation. Normally it will stay around the 1 degree rising prediction. The temperature will still promote comfortable living. Both energy and agricultural sectors will remain possible thanks to technical innovation.
In the RCP 8.5 scenario, temperature will rise from 3 degrees to maximum 6 degrees! It will drastically change Tanzanians habits in terms of energy supply. Disruption of operation and distribution will become a major problem because of the rising demand of growing population and evolving power needs. In the same case, demand for agriculture will rise but production will decrease because of soil infertility. With 80% of the population living on agriculture, feeding Tanzania’s population will be a huge challenge. Moreover, the breeding of goats and cows will face a lack of grasslands and associated difficulties sustaining livestock.
To sum up, in the case of the RCP 2.6 scenario, environmental conditions will increase progressively, leaving time to find innovations and new management methods to keep demand and production at a sustainable level. That also means, that the Tanzanian society will have to take a responsible pathway for its environment by focusing on green energies and avoiding fossils energies.
In the case of the RCP 8.5 scenario, environmental conditions will increase drastically without leaving time for the farmers and energy companies to adapt their methods. Both sectors will be submerged by those changes. Agriculture will face long drought periods making soils incapable of growing any crops, and then will follow long term rainfall causing incessant floods where here also, the farmers will not have the time for transition and crops will be drown and washed away. Electricity will face high demand for cooling, hence conditions for living workers in both extreme periods will be inhumane. Finally, supply, production and distribution in flood periods will be difficult because of poor road conditions.
Africa’s Victoria Lake is the largest tropical lake and source of the Nile River. Climate changes will affect Lake Victoria’s levels of evaporation, temperature, rainfall, and solar energy. According to Emily Beverly, assistant professor of sedimentary geology at Baylor University, the Lake Victoria “could have no outlet to the White Nile in at least ten years”. Which means that every major port will be land closed and Kenya could lose access to the lake in a maximum of 400 years. More than 40 million people are living on the Lake Victoria basin and this result will badly affect their economy. Tanzania depends on the lake’s freshwater because it provides 1 million tons of fish annually. Tanzania’s fishing industry will decrease highly, and all northern regions would be directly affected by this shortage.
Even with an increase of the precipitations in Tanzania (monthly precipitation diagram 2080-2099), in the RCP 8.5 scenario, temperatures will be so high that the lake will dry out too quickly for it to fill up.
The diagram shows the drought impact in the Victoria Lake where more than half of the Tanzanian lake area will be affected.
Moreover, with the rise of temperature, the demand for drinkable water will equally rise.
Global warming will cause the ice on Kilimanjaro and Mount Meru to melt irreversibly.
Neither of these sources will be able to provide drinking water to the districts around
Mount Meru (Arumeru, Arusha, Karatu, Monduli, Ngorongoro) and those around the Kilimanjaro (Hai, Moshi rural, Moshi urban, Mwanga, Rombo, Same) who are completely dependent on them, representing more than 3 million people.
Finally, the rise of sea levels will constrain a majority of Zanzibar’s population to immigrate to the mainland.
Most economic sectors will be affected by climate change (agriculture, energy, fishing, etc.) and the impact on those sectors will result in many adverse effects on the human health of the Tanzanian population. With 80% of the population living on local agriculture, most of them won’t be able to feed themself and starvation will be become through years, common. Because of this malnutrition, many will be inclined to face communicable or non-communicable diseases. According to the World Bank data, 54% cause of death in Tanzania were by communicable diseases, maternal, prenatal and nutrition conditions.
Malaria is still also a major issue in Tanzania. In 2018, the incidence of Malaria was 124 per 1000 which represents 7.4 million people at risk. The rise of tropical temperature and floods will increase the mosquito’s population and therefore the risks of obtaining yellow fever, malaria, Zika virus, chikungunya and many others.
Finally, according to the RCP 8.5 scenario, poverty will increase consequently, and the population won’t be able to face massive floods. 49% of the population living under the 1.90$ per day, with houses on the ground and only a sheet of metal as roof, we can easily imagine the catastrophe.
In conclusion, if Tanzania takes the pathway of green energy which means avoiding both coal and oil, the two major used fossils energies, and if a massive environmental sensibilization campaign is implemented by the government, then Tanzania could likely be faces the RCP 2.6 scenario. As always, the biggest drivers of gas emissions are the public and private sector and there are the ones who have to give the example. Otherwise, the country will face, in the worst-case, the RCP 8.5 scenario. As seen before, these scenarios will be a disaster for a country in development such as Tanzania which faces extreme events and unbearable conditions of life.
Tanzania is lauded as one of the most peaceful and stable countries in Africa. Since its independence, the country has moved to a multi-party democracy that allows a separation of powers. Tanzania, being the mainland, has an Island called Zanzibar. Tanzanian’s economic development largely depends on agriculture. Since the 1990’s, the country has had strong economic growth and was predicted to be one of the fastest economic growth in the world. Nevertheless, it is one of the poorest economies in Africa in terms of per capita incomes, and the overall growth rate is due to the growth of the tourism sectors (safaris, Zanzibar recreational facilities) and gold mining. Most of the people that I have met here have been a tour guide for at least one or two years. It is the case for example of Hadija, who started as a day trip tour guide for Art in Tanzania and has now become a team leader in social sector projects. Tourism is the second pillar of the Tanzanian economy as it provides employment to many jobless people. The development of tourism has led to the improvement of the infrastructures of regions with tourist accommodations. Tanzania expects about 750,000 tourists to arrive in the country every year according to the United Nations Development Assistance Plan (UNDAP).
The main export commodities include gold, tobacco, fish products, coffee, cotton, diamonds, horticulture, and sisal. Tanzania’s main trading partner are China, Switzerland, South Africa, Kenya, and India.
Agave sisalana, known as Sisal, is a plant native to southern Mexico. It’s a very resistant fiber is widely used for ropers, fabrics, or carpets.
The country of Tanzania is mainly composed of two religions: Christianity and Muslim.
Both religions live in perfect harmony thanks to Tanzania’s first president, Julius Nyerere. Each religion is respectful to the other beliefs. The island of Zanzibar is mainly composed of Muslims representing 96% of its population.
On October 24th, 2020, Tanzania’s population was estimated at 59 million whereas on July 1st, 2015 it was at 52 million. Due to high birth rates in the country, on March 18th, 2021, the total population approached t0 61,006,138 which represents 0.77 % of the total world population. In 6 years, Tanzania’s population has seen an increase of 8 million people whereas during the same period the French population has an increase of less than 1 million. Around 37% of the Tanzania’s population is urban.
Also, 44% of the population constitutes of people under the age of 15, 52 % between 15 and 64 and 3.1 % is above 64 years old. Tanzania is built through a variety of cultures and traditions whereas the country is divided into 120 ethnicities, Sukuma being the largest one representing 16% of the total population. Despite aids and grants from the IMF, Tanzania is still dependent on foreign countries due its serious debt. It has an external debt of about $USD 7.9 billion and the debt servicing constitutes about 40% of the government expenditures. In order to repay this debt, the country is forced to qualify for loans from other countries. Adelaide Mkwawa, ICT and Communications Officer at Climate Action Network Tanzania is preoccupied by Tanzanian debt “A lot of aids are coming from other countries such as Switzerland, USA, China but it’s more to have a position in the country then to help. Tanzanians are really dependent on every domain on foreign aids”.
One of the main concerns in Tanzania is the eradication of poverty. According to the World Bank data, in 2017, 49.4 % of Tanzania’s population were living under the 1.90$ per day (the price per day in 2011) which is almost half of the population. The absence of resources to conduct surveys engender difficulties for the World Bank to grasp data updates. In this same year, the World Bank announced that 76.8 % of Tanzanians were under the 3.20 $ a day poverty headcount ratio (PPP in 2011) and 91.80 % under the 5.50 $ one’s. As a comparison, France’s 5.50$ poverty headcount ratio in 2017 is under the 0.1%.
The development of trade in Tanzania has played a key role in eradicating poverty in the country since the private sector controls the growth of the national economy. Major imports include capital goods, intermediate goods, and consumer goods with trading partners such as the USA, China, Norway, UK, Finland, Kenya and Zambia. Trade has led to the attraction of foreign investors due to its proof of the availability of political stability and natural gas discoveries. On the other hand, Tanzania is becoming more dependent on those countries’ financial investments.
Non-Banking financial Institutions and non-governmental organizations play a key role in the deployment of free education to citizens especially to women in the rural areas to make them aware of what is going on in the economy and the environmental issues. The Tanzanian government has established environment sections in all its ministers and a key result of it is the integration of environmental issues into the Medium-term expenditure framework (MTEF) budgeting. This money should help NGOs working for the climate to play a major role. Nevertheless, Adelaide Mkwawa has never seen those governments funds when she was at the United National Appeal Tribunal (UNAT) or at the Climate action Network (CAN) where she currently works nowadays. Same conclusion for Hadija, Team leader at Art in Tanzania, non-governmental organization who promotes volunteer and intern projects in the field of climate change, education, social work, medical and health practices, social media, arts and music, sports, and HIV/AIDS awareness. “For my experiences, I’ve never heard if there were any funds from the government to Art in Tanzania which can help on environmental projects. Maybe the government planned to provide funds to NGOs, but the fund didn’t reach Art in Tanzania yet. It’s my hope that if there are some funds for NGOs, then Art in Tanzania will be among those NGOs to be considered”, Hadija said.
The biggest problem regarding environmental policies is the lack of information and communication. The government doesn’t provide any information about the strategies nor about any concrete actions put in place. Most of the research I’ve done guided me to environmental information provided by other countries or institutions (U.S Agency for international development, United Nations Environment Program, Netherland’s government, etc.) or from the last government environment data updates, which was in 2013. For more recent information, it’s necessary to talk directly with a government employees, but as you can imagine, it’s even harder than to see a cheetah in a safari. According to Adelaide Mkwawa, even the Parliamentarian Assembly for Implementation of Sustainable Development Goals (Parliaments Assembly) has given information and strategies on how to implement the SDG’s in the government budget. That’s where the UNAT’s helps come to a limit. After this, the government takes responsibility for the project. “That’s why there is a lack of information and monitoring. Really hard to find the progress because the government hides a lot of info,” said Adelaide.
The African Union estimates that corruption around Africa represents $50 billions of losses each year. Lots of changes have been made in all African countries to eradicate corruption. Legislation has been drafted and anti-corruption authorities have been formed. However, on the ground, approximately everywhere and especially in Tanzania, nothing seems to have changed. Corruption is a noneconomic factor which creates a gap among the Tanzanians’ people. Since 1968, with the creation of the Anti-corruption commissions in Africa (Bertelsmann foundation 2014), Tanzania has tried to combat corruption. Most of Tanzanian’s presidents ‘ mandates were standing on the fight against corruption. In 1995, President Benjamin Mkapa declared “war” to corruption, and he organized the Presidential commission against corruption to assess the state for corruption and highlight some recommendations. This led to the adoption of the National Anti-Corruption strategy and Action plan (NASCAP) in 1999 and to the implementation of a revised NASCAP from the new president Jakaya Kikwete in 2005. At the end of 2014, a new report was made with a new anti-corruption strategy. All that information proves that, at the end of 2015, corruption had risen compared to 2005 and was less transparent than ever. Despite the government’s efforts, Tanzania continues to suffer badly from rampant corruption at all levels. Good governance is essential for the reduction of poverty and controlling corruption in the country. Tanzania faces both grand and petty corruption due to weak government laws in different agencies. Most of the foreign investors have stated that corruption in areas like taxation, customs service, and procurement, create a difficult environment for them to do business in the country, due to the high demand for bribery.
The diagram above shows us the corruption rate level from low (=1) to high (=6). Tanzania is parts of the countries that observe the highest rate of corruption. In a comparison, the USA and France are not even listed in the World Bank dataset because their respectful rate is under 1. Cape Verde and Bhutan are the two countries who faced the highest corruption with a 4.5 rate.
New president Magafuli, like his predecessors, has made the fight against corruption a point of honor of his mandates. Nicknamed “the Bulldozer” because of its style of leadership earned himself credibility for its fight against corruption. He rebuilt lost trusts with foreigners’ donors and with his population by firing publics officials that was incompetent and corrupt. In November and December 2016, six senior officials in the Tanzania Revenue Authority were fired and pushed away.
Unfortunately, president Magafuli was fighting alone in this battle and against top officials, influential leaders and wealthy powerful people. Despite the efforts and the hope Magafuli was bringing to Tanzanian’s people, corruption is still one of the main problems in Tanzania. As a personal example, I was able to see and experience this drama of corruption through my trip by car between the city of Arusha and the city of Moshi. In only 3 hours, we were stopped no less than 9 times without any reason, and we had to pay between 1000 and 4000 schillings each time. This represents between 50 cents and 2 euros. Sometimes the bill is more expensive, sometimes they let you pass, it’s random. With 91.8 % of the population living with less than 5.5 USD per day and 48.9% under the 1.9USD, corruption is a disaster.
Unfortunately, President Magafuli passed away on this Wednesday, 17 of March 2021 at the age of 61 years old. For instance, vice-president, Samia Suhulu Hassan was sworn in as a president and became the first East African country’s female president. Because of Magafuli 21 days of mourning, President Hassan didn’t expose yet her strategy to avoid Tanzania corruption.
Sectors Promoting Economic Development of Tanzania
As the main economic activity of Tanzania, agriculture contributes to 26% of the GDP and employs about 75% of the labor force. Agriculture, being the key sector of the economy, assists in poverty reduction especially in the rural areas where most people cannot afford to buy food nor have any food security. Not only does agriculture provide employment opportunities but also provides 95% of the food to the people. During the 1990s, agriculture was mainly controlled by the government but after the liberalization of the economy, many people engaged freely in this activity. Some areas received enough rainfall throughout the year making it easy for cultivation while other areas are prone to tsetse flies which badly affect the production of crops.
The lack of access to the banking sector makes it difficult for farmers to obtain loans to carry out their production since only 9% have access to financial services and only 4% are able to obtain loans. Small holder farmers have low education and knowledge resulting in poor quality of crops. This causes the crops to fetch low prices in the markets. Tanzania depends on export of cash crops which increases revenue. Since the 20th century, the main exported commodity is coffee and each year 30 to 40,000 metric tons are being produced whereby 30% is Robusta and 70% is Arabica. But none of this coffee is consumed by Tanzanian people, as they prefer cheaper and low-quality coffee. About $115 million is generated from coffee exportations. Coffee consumption is at 7% of its total production in the national output (Gupta & Bose, 2019).
According to UNESCO (United Nations Educational, Scientific and Cultural Organization), only 24% only out of the 44 million hectares of land have been utilized for the cultivation of crops. Moreover, the existence of water resources, favorable climatic conditions and fertile lands have led to a decrease in poverty condition.
Challenges facing the agriculture sector include:
High rainfall dependency and low irrigation process
Lack of agricultural knowledge and low level of technology such as use of ploughs
Lack of financial access to obtain farm inputs, such as chemical fertilizers and pesticides
Low quality of agricultural production resulting in crops fetching low market prices
Lack of storage facilities and poor infrastructure in the rural areas making it difficult to transport commodities to be processed and sold
To face these challenges, the government created the Tanzania Agriculture Development Bank. This bank was established in 2015 to ensure the implementation of agricultural policies and strategies guiding the performance of the sector in general. Agriculture is also the first sector badly affected by climate change. Without help and innovations in the next 20 years, Tanzania will probably face a decrease of 80% of its actual production, which will plunge the country into deep poverty.
Mining is one of the fastest growing sectors in the Tanzanian economy. In 2013 it contributed to about 3.3% of the country’s GDP, largely changing the economic growth of Tanzania. The country is endowed with various mineral resources such as gold, diamonds, gemstones, nickel, coal, tanzanite, and uranium. Natural gas exploration of about 55 trillion cubic feet has been discovered, helping to supply electricity in the country. UK, India, China, USA, South Africa, Kenya, Netherlands, Oman, Canada, and Germany are the main investors in the Tanzanian mining sector. Like in many countries around the globe, the mining sector demonstrates multiple challenges for climate change such as health security and illegal practices. Here are some examples of the impacts of the Mining Sector in Tanzania:
Silica dust affecting the miners as well as tuberculosis disease
Existence of illegal mining in the country creating risk to the workers
Previous Minister of Mining and Energy resource was found guilty after conducting frauds deals and supplying gold to some firms
Child labor employed in mines
There was a serious case on the 17th of April 2015, where 19 people were killed after the collapse of an illegal mine near the Bulyanhulu Gold mine in the Kahama district. Many children were rescued from the same collapse. Most of the developed countries involved in the Tanzanian mining sector, already know these problems but the economic interest is too high to politically be involved in the reduction of those challenges.
Rural areas in Tanzania do not have access to the banking sector because people do not own valuable assets which would support loan extensions. There is also the lack of education on how banks operate. Most of the rural population have a day-to-day life, only using cash and have no use of credit cards. Even people with a reasonable income mainly use cash. Indeed, if you have a flow ,even low, of cash entering your bank account, then institutions know that you are running a business and then lots of fees appear. That’s why most people use cash in their daily lives and apart from tourist’s facilities, credit cards are not accepted.
Transport is very important in any economy to facilitate smooth trade. Tanzanian roads are maintained under the management of an agency called TANROADS “Tanzanian Roads” which has been able to improve the national roads. Road safety still remains a major problem due to poor maintenance of vehicles, overloading, flooding, and poor driving. Tanzania is planning to import about 138 Chinese modern buses into Dar es Salaam. This is due to the support provided by the government through the improvement of the marine transports by modernizing ports and increase spending on infrastructure. The port currently collects over TZS 40 billion per month which represents almost 18 million euros.
Welcome to our new four-part blog. In a series of blogs, I will be discussing the effects of climate change on our planet and the consequences it will have if we do not do anything about climate change.
Before discussing the specific case of Tanzania, it is important to understand the definition of climate change and the consequences of its impact on our planet. Firstly, it’s critical to understand the difference between climate and weather. Weather is an instantaneous and local situation of observable things such as, temperature, precipitation, wind, and so on. Climate, on the other hand, is a statistical description based on the averages and variability of the same variables (temperature, wind, etc.) over long periods of time and on a global scale. For example, the difference between weather and climate would be the comparison between a student’s grade on an exam versus his or her yearly average.
In this report, I will focus on the effects of climate change on our environment. Since the beginning of time, the climate has changed naturally with the ice ages. For 11,000 years now, our planet has been in an interglacial era (average temperature has similarly been constant over many years, in summer the snow melts and the ice surface slowly shrink around the globe), i.e., our planet is warming at its own pace. However, climate change is different, our planet is warming much too fast. Previously, losing 5 degrees would take thousands of years, nowadays, we have already gained 1 degree in less than a century! Indeed, our greenhouse effect is completely out of control. The concentration of “greenhouse gases” (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and water vapor (H2O), etc.) in the atmosphere has increased at an unprecedented rate in recent years. The higher the level of CO2, the higher the temperature. For simplicity’s sakes, we will give for the greenhouse’s gases the abbreviation GHG’s. This diagram shows the natural evolution of the amount of CO2 during the ice ages and interglacial.
The exponential increase in GHGs over the last century is therefore leading to a completely new climate disturbance that is causing global warming to become more and more alarming and in need to be controlled.
But what has caused climate change?
From the diagram above, it is clear that the human race has a large share of the responsibility for this phenomenon. Before the 1850s, CO2 in the atmosphere played its natural role as a greenhouse gas at a relatively stable rate. Since then, human activities have contributed greatly to its increase, particularly through economic growth as standard of livings have increased drastically. As wealth rises, humans develop continuous need to consume, thus increasing their GHG’s impact. This phenomenon primarily started in Europe, and then progressively spread in all the industrialized countries. Population growth has actively participated in climate change as we have gone from 1.2 billion people to 7.7 billion between 1850 and 2019.
Parallel with these two phenomena, several industrial revolutions (steam, electricity, nuclear power, etc.) were born, transforming more and more natural resources into energy or materials. Population growth, coupled with growth in GDP per capita, have led to an upheaval in energy consumption on our planet, and now 80% of the world’s energy comes from fossil fuels or hydrocarbons (oil, gas, coal). Fossil fuels constitute a stock that was formed over hundreds of millions of years by the slow decomposition of the remains of living organisms. However, these fossil resources are exploited by humans during which a very large quantity of carbon that was normally buried underground for millions of years is suddenly released into the atmosphere in the form of CO₂. Changes in land use also significantly impact the balance of natural carbon stocks: deforestation, agriculture, the draining of swamps, and of peat bogs for example. The carbon cycle is therefore strongly impacted by human activities and can no longer regulate itself normally. The Earth is no longer able to regulate this unnatural flow through its physical and biological mechanisms. Unfortunately, the situation is only getting worse as human activity continuously disrupts the carbon cycle, but it is becoming more and more consequential each year.
This diagram shows that we previously needed 130 years to emit 1000Gt (gigatons) of CO2 equivalent and nowadays we only need 30 years to emit the same amount again. At this rate, we will only need 20 years to produce another 1000 Gt.
Climate change has emerged as a potentially existential threat all across the globe that poses a serious risk to the survival of mankind and sustainable development. Over the last few decades, the world has witnessed changes in weather patterns as a result of global warming and human-caused greenhouse gas emissions. Based on a numerous lines of evidence, it is now more certain than ever that climate change is a threat multiplier that can amplify the effects of existing dangers. These threats include human security, scarcity of natural resources, environmental degradation, and poor economic growth.
The United Nations General Assembly set up the 17 Sustainable Development Goals in 2015 which serve as a blueprint for a sustainable future to be achieved by 2030. The 13th Sustainable Development Goal of the United Nations talks about Climate Action. The goal discusses the critical impact of climate change and encourages developing countries to move towards low-carbon emission in the environment. The United Nations Environment Program (UNEP) is a separate organisation working within the UN that deals with climate change and other environmental issues. The UN aims to adapt to low carbon development especially in the vulnerable regions that contribute towards climate action and sustainable natural resource management through collective action. Most of the states in the world are affected by climate change with East Africa being one of the most affected regions.
Tanzania is suffering the brunt of the consequences of climate change in East Africa. The agricultural-based economy of Tanzania has become vulnerable to the extreme climatic conditions. The majority of the population is located in the rural areas which heavily relies on agriculture and farming that is threatened by rising temperatures, droughts, and extreme rainfalls. The country is home to the world’s largest river system, the River Tanzanian. Despite immense water resources, Tanzania struggles with a shortage of water both spatially and temporally, which is worsened by the climate on its nine main river basins. In the recent years, there has been a severe decline in the water level in Lake Tanganyika, Lake Victoria, and Lake Jipe, as well as a decrease in the water level of about 7 kilometers in Lake Rukwa during the last fifty years. These are connected with climate change and are endangering towards socio-economic activities. The effect also puts the country’s hydropower system at risk. Furthermore, diseases such as diarrhea and malaria remain one of the prime causes of casualties in the country especially in the urban settlements consisting of poor infrastructure prone to flooding and increased temperatures.
Tanzania’s economy relies on its natural and environmental resources where a good number of people depend on fisheries for their income which are at risk from rising sea waters and freshwater temperatures. Tourism is another aspect that has the potential to boost the economy of Tanzania as the country has a tropical climate and is home to wildlife, forests, beaches, mountains, rivers, lakes, and minerals. The attractions are found in abundance in national and marine parks, historical and cultural sites, and recreational sites. Currently, tourism generates 17.5 per cent of GDP and 25 per cent of export revenues, making it an important economic sector. Due the unpredictability of climate it is endangering the ecosystem services on which tourism relies. For example, the Serengeti National Park has been famous tourism spot for the wildlife migration for decades, contributing significantly to Tanzania’s economy and serves as a key source of employment. There is a growing fear that the climate has shifted dramatically, potentially affecting wildlife tourism.
Threats to the sustainability of the natural resources and environmental degradation remain an issue in Tanzania such as the untimely harvesting and usage of natural resources, unsupervised cultivation process, and trespassing on water sources. Collectively, these can seriously affect the sustainable development goals of a country. Due to the unsustainable consumption of resources, there can be problems in the production of sources that may affect livelihoods. In addition to that, they can lead to the deficiency of food which could eventually lead to poverty. An increase in the population and high reliance on agriculture becomes rather burdensome on the environment and its natural resources which contribute negatively to climate change and water-deficient regions.
One of the leading contributing factors to the environmental degradation is the unsustainable management of land and watershed. Many challenges are still needed to be tackled to reduce this issue including unexpected growth of human settlements, wildlife hunting, illegal farming and livestock, uncontrollable bushfires, weak inter-sectoral association, and stakeholder linkages. This may lead towards the social and economic development of the country as well as reduce poverty. The Tanzanian Government has marked the water-oriented issues as a major factor that has affected the environment. This has led to the implementation of national policies and necessary plans and strategies needed to tackle it. The visibility of climatic changes in Tanzania is increased by 60% which are seen in the form of a decrease in water sources, land degradation and the reduction in agricultural land. The Government also tends to focus on carbon emission with the protection of ecosystems and biodiversity, the saving of wildlife to abolish the hunting system as a means of income, reducing vehicle usage and improving urban planning in the country to promote urbanization. It also placed environmental sections under the sector ministries to ensure and monitor the environmental issues as well as raising awareness amongst the community. The Government also needs to guarantee that efforts are being made in terms of the development of the environment and climate change in national as well as subnational plans.
The United Nations Development Program (UNDP) is one among many partners of the Government of Tanzania that has aided in the development of the environment and contributed to measures regarding natural resources and climate change issues. The UNDP encourages the Government and respective communities in terms of sustaining the environment and contributing to the reversal of environmental degradation. As long as the correct policies are implemented, the chances for preserving the ecosystems in terms of food, energy, wood i.e., timber, clean water, consistent climate etc. are possible. Over the past few years, Tanzania has recently experienced high growth rates of about 7.4%.
The impact of climate change has had a huge effect on the incomes of the people in Tanzania. It has had a severe impact on the economy, agriculture, natural resources, and livelihoods of people which exposes the vulnerable part of the country. It is, to say the least, that the Government of Tanzania is to be respected for the progress it has made regarding the development and exercising of policies and strategies to prevent degradation and the protection of the environment. The Government tends to cater to the environmental needs of the country and maintain its natural resources as a means of saving economic and social development. This would mean effectively establishing immediate measures to improve the damages caused. The Government also needs to guarantee that efforts are being made in terms of the development of the environment and climate change in national as well as subnational plans.

Climate change is having an instrumental impact on water stocks in Eastern Africa. This is consequently impacting many citizens’ enjoyment of their human rights. The United Nations suggests that ‘water is the primary medium through which we will feel the effects of climate change’ (United Nations, 2018). This is because higher temperatures and more extreme, less predictable, weather conditions are projected to affect the availability and distribution of rainfall and further deteriorate water quality. As of 2019, 12% of the world population drinks water from unimproved and unsafe sources and more than 30% of the world population, or 2.4 billion people, live without any form of sanitation (United Nations, 2020).
Specifically, in Eastern Africa, 75% of Africa’s population could be at risk of hunger. This is because 75 million hectares of land currently suitable for agriculture is being lost in sub-Saharan Africa due to drought. This is a matter pertaining to human rights for a number of reasons. Contaminated water and poor sanitation are linked to the transmission of diseases such as cholera, diarrhea and polio. Inadequately managed water and sanitation facilities expose individuals to health risks that would be otherwise preventable. It is predicted that approximately 842, 000 people are to die each year from diarrhea as a result of unsafe drinking-water, sanitation and hand hygiene.
This post with consider potential climate policies from a variety of time scales and their effectiveness at combating the issue of water scarcity in Eastern Africa. Some of the policies to be assessed will include the re-use of wastewater, to recover water and improved sanitation.
The current population of Eastern Africa is approximately 451, 600, 500. However, 37% of people in the world that do not have access to safe and clean water live in this region. Access to sanitation in sub-Saharan Africa is in fact declining with only 31% of people able to access a toilet (6% less than that reported in 2006).
In Tanzania, the population is approximately 60,712,700, with 80% of people living in rural areas. These rural areas are especially sparsely population, with as low as 1 person per square kilometers. This increased to approximately 53 people per square kilometer in the water-rich mainland highlands. It is estimated that up to 80 percent of Tanzania’s rural population relies on use of natural resources to sustain a livelihood, which makes stewardship of these resources a fundamental priority for Tanzania’s continued stability and growth. However, 4 million people in Tanzania lack access to an improved source of safe water, and 30 million don’t have access to improved sanitation.
Agricultural Production Data
These statistics have instrumental implications for the production of agriculture in sub-Saharan Africa and Tanzania. This is because approximately 93% of water withdrawn from the Tanzanian environment is used for agriculture. It is therefore of great importance that Tanzanian communities have access to safe and clean water. Agriculture accounts for 27% of Tanzania’s gross-domestic product (GDP) and provides employment for the majority of the nation’s population. Moreover, the livestock sector contributes 7% to the country’s GDP. The sector is severely constrained by low livestock reproductive rates, high mortality and high disease prevalence.
By the 2080s, land unsuitable for agriculture in sub-Saharan Africa due to severe climate, soil or terrain constraints may increase by 30 to 60 million hectares (United Nations, 2019). It has been projected that, as a result, there will be a 4.9% decrease by 2080 in agricultural Gross Domestic Product (GDP) (International Institute for Applied Systems Analysis, 2020). This will have a detrimental impact on the economy of rural Tanzania that relies considerably on agriculture production and livestock to supports livelihoods.
Human rights and vulnerable groups in rural Tanzania
Climate change, and its effects on water stocks, has a variety of impacts on individuals. Some of the factors include whether they live in rural or urban areas, whether they live in an area that receives high rainfall or whether they belong to a group that is particularly vulnerable or marginalized.
Children and young adults are particularly vulnerable to climate change and water scarcity. Children make up approximately 44% of the Tanzanian population and all are vulnerable to poor health, malnutrition and to the general lack of basic needs, at different levels depending on the structure and assets commanded by their families. Children under-five are mostly vulnerable to diseases, malnutrition, and inadequate care.
By 2002, 4.1 million out of 10.2 million children in Tanzania aged 5-14 years were not attending school. The often-long distances to primary school is a problem to about 30% of households. That may discourage children from attending school and receiving an education which commonly includes information about the importance of access to water and sanitation. As we shall see later on, schools are also increasingly becoming an important place for children to access clean water and sanitation facilities.
Women are especially vulnerable to the implications of water scarcity due to their existing lack of social mobility. When this is paired with food insecurity, limited access to health, sanitation and education, the result is a low income. This perpetuates social isolation and as a result it puts powerful constraints on their capacity to make a living. Moreover, poor access to water and other household services, often results in women spending long hours and walking long distances to collect these amenities. Finally, many women experience stressful childbearing and rearing due to inadequate or poor-quality maternal health care, sanitation and a clean environment.
c) Disabled individuals
One of the core characteristics of persons with disabilities is their limited mobility, which reduces their opportunities for participating in income generating activities to increase their wealth. This consequently limits their access to basic needs such as food, health services and education. When this preexisting vulnerability is paired with intense water scarcity, disabled individuals can become some of the most marginalized in rural communities.
d) Individuals with a long-term illness
Finally, individuals with a long-term illness are at an acute health risk which water scarcity can perpetuate. In 2001, approximately 28% of the rural people fall into this category. In Dar es Salaam and other urban areas, the figures decreased to approximately 19%. By any means this is an enormous figure as more than a quarter of the population falls into this category. Poor nutrition and health services that weaken the health status of the members of poor households exposes them to the risks of contracting diseases and living with ill health. These individuals could be vulnerable to poverty, as they cannot work. Access to clean water is therefore instrumental in preventing the decline of their condition.
Tanzanian Government Policies for Climate Change
There is an abundance of legal provisions that support the securing of access to clean water. Africa is particularly advanced in comparison to the rest of the world in this respect. The African Charter of Human Rights was the first broadly ratified international document which stipulated the right ‘to a general satisfactory environment’ and referred to the right as one of ‘peoples’ in a community, as opposed to individuals. This has the effect of emphasizing both the rights and duties of individuals consistent with African conceptions of human beings as integral members of a larger community.
The Tanzanian government have provided the Environmental Management Act 2004 which aims to provide the goals of this charter. Section 4(1) provides that every person living in Tanzania shall have a right to clean, safe and healthy environment and section 4(2) states that this shall include the right of access by any citizen to the various public elements or segments of the environment for recreational, educational, health, spiritual, cultural and economic purposes.
The 2004 Act established the existence of the Tanzanian National Environment Management Council. As per section 17(1) the object and purpose for which the Council is established is to undertake enforcement, compliance, review and monitoring of environmental impact assessment. As per section 17(2) the Council shall prepare and submit to the Minister a bi-annual report concerting how it has implemented the provisions of this Act and fulfilled the objects and the purpose for which it was established.
However, these provisions provide of no more than a broad and general right. The Food and Agriculture Organization of the United Nations has suggested five policy responses to implement such a goal.
Include adaptation and mitigation measures for agricultural water management in national development plans.
Promote technical and management measures to improve the flexibility of rainfed and irrigated agriculture and reduce water losses in irrigated production systems.
Improve knowledge on climate change and water and share good practice among countries and regions.
Promote risk management in national policies through better monitoring networks and innovative insurance products.
Mobilize adaptation funds to meet the challenges of water and food security under climate change.
5.1. School Water, Sanitation, and Hygiene (SWASH) guidelines
The School Water, Sanitation, and Hygiene (SWASH) guidelines provide one example of the Tanzanian government adopting some of these policy responses. The guidelines aim to increase education and awareness of the importance of access to water and sanitation. It is a toolkit with both hardware and software aspects to bring about changes in the hygiene behavior of students and, through these students, in the community at large.
They suggest a number of systems and methods to improve sanitation, water preservation and water collection.
Protected springs offer a source of water that is often free from pathogens. If the dissolved minerals are within permitted parameters, they can provide good quality drinking water. SWASH advices that at the collection point of the spring, appropriate civil construction can prevent this water from being contaminated. Moreover, the surrounding environment of the spring should not be degraded, and advices against deforestation or contamination in this area especially.
Shallow wells or hand dug wells are a simple method of making use of groundwater. They are only suitable for regions that have an especially high-water table and good water quality. However, SWASH provide two systems – one automatic and one manual – for the collection of water. Rainwater harvesting is another simple and yet effective way of collecting water.
However, as SWASH highlights, the weakness in these methods often comes in the form of sanitizing the water before drinking it. It is necessary to follow the methods provided and removing any solid material and boiling the water to remove any bacteria. This reduces the chances of contracting waterborne diseases.
With regard to sanitation, ventilation improved pit (VIP) latrines serve to provide a clean and cheap way to store human waste. A draft is passed through the collection area of the pit which means that the smell and insects cannot linger. This improves sanitation and the appeal of using the facilities.
Finally, the guidelines significantly stress the importance of using hand washing stations. This is a simple but highly effective way in which students can reduce the likelihood of carrying diseases on their body and spreading infection.
The SWASH guidelines provide an incredibly important educational tool for schools to implement these systems. However, a lot of the structures require advanced infrastructure in order for their long-term effectiveness. There consequently needs to be much more investment in these rural communities in order for these systems to be of the best quality they can be. For example, the VIP latrines require a high level of construction to prevent the human waste from contaminating the surrounding groundwater and soil.
Moreover, in order for the program to work as intended, its information and guidance needs to be spread beyond the school environment and implemented in rural communities. This distribution of information is arguably the most effective way of mitigating the impacts of water scarcity in these regions. The important work of Non-Governmental Organizations such as Art in Tanzania in distributing and educating local communities is an example of this.
