Tanzania is the largest country in East Africa and has a coastline along the Indian Ocean. Much of the country consists of highland plateaus situated between 900 and 1,800 meters above sea level, with mountain ranges across several regions. The terrain becomes flatter toward the coast. Tanzania’s climate is largely influenced by altitude, ranging from tropical lowlands in the east to cooler highland climates in the north and southwest. The country is vulnerable to the impacts of climate change across several sectors, including public health, energy supply, infrastructure, water resources, and agriculture (World Bank Group, n.d.).  Climate change is expected to intensify the risks associated with extreme weather events, including rainfall variability, prolonged droughts, and floods (ibid.). 

 Air temperatures in Tanzania are projected to increase under all emission scenarios, with the annual number of very hot days expected to rise significantly (GIZ, 2021).  Sea level rise threatens coastal communities and may lead to saline intrusion, affecting water supplies and biodiversity (ibid.). Precipitation projections vary, with some models indicating a substantial decrease — more than 42mm by 2080 compared with 2000 — while others suggest little overall change (ibid.).  Water availability may decline significantly in some regions, potentially by up to 76 percent under both RCP2.6 and RCP6.0 scenarios (ibid.). Changes in water flows have already affected Tanzania’s capacity to generate and supply electricity, particularly hydropower, with droughts linked to climate change reducing generation in recent years (United Republic of Tanzania, 2007). 

In its first NDC (2021)  Tanzania outlines a range of adaptation measures across sectors such as forestry — including participatory sustainable forest management, coastal and marine ecosystems and fisheries, such as promoting livelihood diversification for coastal communities, and energy, including climate-smart rural electrification initiatives.
