Chapter 01 : The natural resources of Tanzania

Meaning of resources

Resources are things that enable us to achieve our goals or meet our needs. We use resources in our daily activities, such as production activities or learning. Resources make our lives easier and better.

Types of resources

Activity 1

Think of starting a vegetable farming project. Prepare a table showing the important resources needed and state the usefulness of each resource in implementing the project.

Resources are of different types, including natural resources such as land, water, forests, animals, and minerals; human resources such as skills and labour; and capital resources such as money, machines, buildings, and other infrastructure. Each of these resources helps us in different ways to attain our goals and improve our lives. In this textbook, you will learn more about natural resources.

Natural resources

Natural resources are things and raw materials found in the natural environment that can be used by human being for different purposes. Natural resources include air, natural gas, water, sunlight, land, minerals, oil, forests, and animals. Broadly, natural resources are divided into two main groups: renewable and non-renewable resources.

Renewable resources

Renewable resources are those that can constantly regenerate themselves relatively in short periods after being used. Sunlight, wind energy, water and forest are good examples of renewable resources.

Non-renewable resources

Non-renewable resources are finite resources that are not easily regenerated or take a long time to form; thus, they become exhausted after use. Examples include oil energy, minerals, fossils and natural gas.

Natural resources found in Tanzania

Activity 2

Observe different places surrounding you, then list the natural resources found in the area.

Tanzania has valuable natural resources that contribute to the nation’s economic growth and development. Such resources need to be identified, conserved, and developed for the benefit of the present and future generations. The following are some of the natural resources found in Tanzania:

Minerals

Tanzania has many mineral resources, including gold, tanzanite, diamonds, coal, copper, salt, tin, nickel, uranium, and other precious stones. It is one of Africa’s top producers of gold, with substantial gold reserves spread over several regions. Tanzanite is a precious mineral found only in Tanzania. The mining sector in Tanzania is essential to the country’s economy because it attracts foreign investment and generates revenue through export of minerals. Figure 1 represents some of the minerals found in Tanzania.

Land

Tanzania is rich in land resources, including fertile land and large grazing areas. Tanzania has fertile soil suitable for cultivating various crops like coffee, tea, tobacco, maize, beans, sunflowers, paddy and other crops. The country also has large tracts of land for raising animals like cattle, sheep, and goats. Some areas in Tanzania are designated as wildlife parks and reserves, protecting plants, animals, and other living organisms. Other land is used for human settlements, industries, and businesses. Thus, land is an essential resource that contributes to Tanzania’s economic growth and the well-being of communities and improves the lives of individuals.

Water

Water is an essential resource for all living things, including humans, animals and plants. Tanzania has many water resources found in different areas, sources, and regions of the country, including dams, rivers, lakes, the ocean and groundwater. Water resources contribute to the country’s economy and people’s daily lives. The Indian Ocean, Lake Victoria, Lake Tanganyika, and Lake Nyasa are some of the significant water bodies. There are also rivers, including Rufiji, Ruvuma, Malagarasi, Ruvu, Wami, Kagera and Pangani, and large dams like Julius Nyerere Hydropower, Mtera, NyumbayaMungu and Kidatu. People and other living organisms use water to sustain their lives.

Additionally, the water resources support the development of the blue economy-related sectors. The blue economy in Tanzania involves a wide range of sectors related to the use of oceans, coasts and fresh waters like rivers, lakes and dams. The blue economy-related sectors include fishing, transportation, tourism, agriculture and energy, essentially electricity generated from water, natural gas and oil. The blue economy also contributes to improving livelihoods and employment, at the same time as emphasising the preservation of biodiversity and promoting sustainable use of water resources.

Forests

A forest is an area with a collection of many large and small trees, shrubs and grasses. Tanzania has various types of forests, covering about 40% of the total land. These forests include mountain forests, miombo woodlands, and mangroves. The forests provide shelter for many animals and other living organisms, making them essential for wildlife and other living things. Forests are valuable as they provide wood for construction, firewood for cooking, and medicinal plants. By absorbing carbon dioxide from the atmosphere, forests also assist in regulating the climate and maintaining the purity of the air and water. Forests are a source of income for many people who engage in beekeeping, harvesting fruits, and gathering other natural forest-related goods. Forests are therefore important for the local population in their respective areas and they conserve the environment.

Wildlife

Wildlife are natural resources, which include all animals and birds that live in a natural environment without being introduced by humans. Some examples of wildlife include elephants, lions, rhinos, buffalo, leopards, antelope, zebras, giraffes, ostriches and many others. Tanzania is home to famous African wildlife including the animals known as “The big five”, which are the lion, elephant, rhino, buffalo, and leopard, as shown in Figure 2. The wildlife is largely found in national parks, conservation areas and game reserves covering approximately 38% of the total land area in Tanzania. Some of the national parks and conservation areas are the UNESCO World Heritage Sites, including Ngorongoro Conservation Area, Serengeti, Nyerere and Kilimanjaro National Parks.

Tanzania has authorities responsible for managing protected areas. The Tanzania National Parks Authority (TANAPA) manages all national parks, and the Ngorongoro Conservation Area is managed by the Ngorongoro Conservation Area Authority (NCAA). The game reserves, such as Ugalla, Moyowosi, Rungwa, Biharamulo,Ibanda, and Selous, are managed by the Tanzania Wildlife Management Authority (TAWA). Wildlife resources provide various benefits that contribute to the development of the nation through tourism, wildlife education culture national heritage and animal harvesting.

Energy

Tanzania has various energy resources, both renewable and non-renewable. The country mainly depends on hydroelectric, natural gas, and biomass energy to generate electricity. Hydroelectric forms a large share of the electricity produced in the country, although its production is affected by drought conditions. Coastal areas rich in natural gas reserves have become a key energy source for the country’s electricity generation and industrial use. Biomass, particularly from wood and agricultural residues, is commonly used for cooking, especially in rural areas. In addition, Tanzania has other renewable energy sources such as wind and solar, which help the country reduce dependence on oil, gas, and hydropower.

In general, Tanzania’s natural resources significantly contribute to the economy through sectors such as agriculture, mining, tourism, and industry. The government is implementing strategies to ensure these resources are used sustainably, for the benefit of the current and future generations.

This river originates in the Kipengere Mountains and flows through the Usangu plain, passing through Ruaha National Park and Nyerere National Park before joining the Rufiji River. It is one of the important rivers in Tanzania, contributing to the country's ecological system and economy.

Other rivers in Tanzania include the Kagera River, which is found in Kagera region and empties its water into Lake Victoria, The Malagarasi River, which is found in Kigoma region, flows into Lake Tanganyika, and the Mara River, which is found in Mara region, also empties into Lake Victoria.

Lakes found in Tanzania

Lake Victoria

Lake Victoria is the largest freshwater lake in Africa and the second largest in the world. The lake is positioned in Tanzania, Kenya, and Uganda. Tanzania covers approximately 49% of the lake's area, followed by Uganda by 45% and Kenya by 6% of the total area. The lake covers about 68,000 square kilometres. In Tanzania, Lake Victoria is found in Mwanza, Kagera, Mara, Geita, and Simiyu regions. Its several significant islands, including Ukerewe Island, the largest island in Lake Victoria and Tanzania in general, covering about 530 square kilometres, and is among the districts in Mwanza region, as well as the Saanane Island, which is a national park. Additionally, Lake Victoria is one of the primary sources of the Nile River, which flows through South Sudan, Sudan, Ethiopia and Egypt before ending in the Mediterranean Sea.

Lake Tanganyika

Lake Tanganyika is the East African Rift Valley Lake, located in the western part of Tanzania, in Kigoma, Rukwa, and Katavi regions. The lake is also found in the Democratic Republic of Congo (DRC), Burundi, and Zambia. Tanzania covers about 46% of the lake's area, approximately 32,900 square Kilometres, making it the most significant portion compared to other countries. Lake Tanganyika is the longest freshwater lake in the world, stretching 673 Kilometres from North to South. Similarly, Lake Tanganyika is also the second deepest lake in the world and the first deepest in Africa with a depth of 1,470 meters.

Lake Nyasa

Lake Nyasa is the East African Rift Valley lake, covering an area of about 29,600 square Kilometres. It is the third largest and second deepest lake in Africa, following Lake Tanganyika. Tanzania shares approximately 50% of its area. Lake Nyasa forms part of the southern border between Tanzania and Malawi. In Tanzania, Lake Nyasa is found in the regions of Ruvuma (Nyasa districts), Mbeya (Kyela district), and Njombe (Ludewa district).

Lake Rukwa

Lake Rukwa is located in the East African Rift Valley in southwestern Tanzania. It is situated within the regions of Rukwa, Songwe, and Katavi. This saline lake is known for its high salinity and presence of soda ash. Half of the lake lies within the boundaries of Katavi National Park, making it an important ecological area. Other Important lakes in Tanzania include Lake Manyara, Eyasi and Natron.

Lake Manyara is a saline and soda lake in the East African Rift Valley, within the Manyara Arusha regions, near MtowaMbu and Karatu towns. The lake is known for its unique ecosystem and is home to various bird species such as the flamingo. This lake is part of Lake Manyara National Park, which is known for its diverse wildlife and scenic landscapes.

Lake Eyasi is also a saline lake found in the Karatu district, in the Arusha Region in northern Tanzania. The lake lies within the Rift Valley, southwest of the Ngorongoro Conservation Area. Lake Natron is a highly saline and alkaline lake in northern Tanzania, the Arusha Region, and the Ngorongoro district bordering Kenya. The lake is within the East African Rift Valley, near OldoinyoLengai volcanic mountain. The lake is famous for its remarkable red or pink coloured water caused by salt-loving microorganisms such as cyanobacteria. These organisms produce special pigments that appear red or pink, especially when the water decreases and the salt increases.

All these lakes play an essential role in promoting the blue economy. For instance, fishing is a source of income for communities around these areas and contributes to the national economy. Also, these lakes facilitate transportation services and tourism; for example, the clear water and sandy beaches attract tourists to the Mbamba Bay area in the Ruvuma region. Figure 9 shows the distribution of rivers and lakes found in Tanzania.

Overall, Tanzania is rich in water resources that contribute to the nation's development, particularly in agriculture, energy, trade, fishing, industry, tourism, and transportation.

Energy resource distribution

Tanzania has several energy resources, including renewable and non-renewable sources, which contribute to economic development and address electricity needs. The following are some of the important energy sources available in Tanzania.

Natural gas energy

Tanzania has rich natural gas resources, mainly found in Lindi and Mtwara regions, where the first discoveries were made in 1974 in SongoSongo Island (Lindi) and 1982 in the Mnazi Bay area (Mtwara). Presently, more natural gas deposits have been discovered in deep-water areas of the Indian Ocean in these two regions. Natural gas is important for the national economy as it generates about 50% of the country's electricity through gas processing plants, such as those in Madimba (Mtwara). Natural gas is used in industries, transportation (including cycle rickshaws and vehicles) and cooking. Natural gas also contributes to national revenue through export to neighbouring countries such as Burundi, Malawi and Uganda. Tanzania also aims to increase natural gas exports to the Democratic Republic of the Congo, Kenya, and Zambia.

Oil energy

Oil exploration activities in Tanzania began in 1952. Until now, Tanzania has signed contracts with various companies for oil exploration. However, Tanzania still plays a significant part in the East African Crude Oil Pipeline (EACOP) project, which runs from Hoima in Uganda to the Tanga region in Tanzania. The implementation of this project started in 2022 and is estimated to be completed by 2026. Upon the completion of the project, it will contribute to the development of the economy and energy sectors in Tanzania.

Hydropower, solar, and wind energy

Water, solar, and wind projects are essential for promoting the energy sector in Tanzania. For example, there is wind power project in the Singida region. In addition, the Julius Nyerere Hydropower Project on the Rufiji River. Moreover, more hydroelectricity is produced at the Mtera, NyumbayaMungu, and Kidatu dams.

The relationship between Tanzania’s natural resources and development activities

Tanzania’s natural resources are essential to the country’s development activities. Fertile land, minerals, water, and forests provide a solid foundation for the growth of various sectors, including agriculture, fishing, construction, energy, tourism, and industry. The effective use of these resources encourages economic growth, social well-being, and environmental sustainability. The following are some development activities triggered by natural resources availability in Tanzania.

Developments in the fishing sector

Natural resources in Tanzania play a crucial role in the development and sustainability of the fishing sector. Water resources are the mainstay for the development of this sector and for promoting the blue economy. Major lakes such as Lake Victoria, Tanganyika, and Nyasa are habitats for various fish species, including Nile perch, tilapia, catfish, sardine, kampango, kamongo, migebuka, and others. Rivers like Rufiji, Ruvuma, Wami, Ruvu, and Pangani also contribute to fishing, providing species like mudfish, lungfish, kumba, pale, kambale, perege, kamongo, ngogo and kitoga. The Indian Ocean offers opportunities for catching fish such as octopus, crabs, prawns, tasi, vidu, changu and kolekole. These water resources serve as breeding and production grounds for fish, ensuring the long-term viability of the fishing sector. Fish provide food for communities and are also domestically and internationally, increasing individual and national income. In addition, the development of fisheries sector and the blue economy largely depend on the availability and proper management of water resources.

Developments in the agricultural sector

The presence of fertile land, nutrient-rich soil and favourable climatic conditions has contributed to the successful crop production such as maize, rice, potatoes, cassava, coffee, tea, tobacco, sunflowers, beans, vegetables, and fruits. Tanzania also has water resources from rivers, lakes, and groundwater, which are used for irrigation, especially in areas with low rainfall. These natural resources support subsistence and commercial agriculture and employ many of the population. Better management and investment in these resources are essential to increase opportunities within the agricultural sector and promote the blue economy in Tanzania.

Developments in the mining sector

The presence of many mineral deposits in Tanzania provides a solid basis for the growth of the mining sector, which is one of the key contributors to economic development. Gold, in particular, has contributed to the country's revenue by providing export products and attracting significant foreign investment. The mining of tanzanite, a precious gemstone found only in Tanzania, has placed the country on the global map as a leader in mining these rare minerals. The mining sector also benefits from a large reserve of coal, which is used for industrial electricity production and export. The availability of minerals such as limestone and phosphates has also supported the growth of industries like cement manufacturing and fertiliser production, thereby contributing to the expansion of the mining sector. Thus, with good management and investment in Tanzania's mineral resources, there is a potential for significant economic development and job creation, and poverty reduction.
