Climate change in Tanzania

Köppen climate classification map for Tanzania for 1980–2016
2071–2100 map under the most intense climate change scenario. Mid-range scenarios are currently considered more likely[1][2][3]

Climate change in Tanzania is affecting the natural environment and residents of Tanzania. Temperatures in Tanzania are rising with a higher likelihood of intense rainfall events (resulting in flooding) and of dry spells (resulting in droughts).[4][5]

Water scarcity has become an increasing problem and many major water bodies have had extreme drops in water levels, including Lake Victoria, Lake Tanganyika, Lake Jipe, and Lake Rukwa.[6][4] Tanzania's agricultural sector, which employs over half of the population, is particularly vulnerable as farmers are predominantly dependent on rainfed agriculture.[6] On the other hand, increasing intense rainfall events have resulted in flooding across the region, which has damaged infrastructure and livelihoods.[7] A high percentage of the population of Tanzania lives along the coast and are dependent on fisheries and Aquaculture[6] Sea level rise and changes in the quality of water are expected to impact these sectors and be a continued challenge for the country.[6]

Tanzania produced a National Adaptation Programmes of Action (NAPAs) in 2007 as mandated by the United Nations Framework Convention on Climate Change. The NAPA identifies the sectors of agriculture, water, health, and energy as Tanzania's most vulnerable sectors to climate change.[8] In 2012, Tanzania produced a National Climate Change Strategy in response to the growing concern of the negative impact of climate change and climate variability on the country's social, economic and physical environment.[9] In 2015, Tanzania submitted its Intended Nationally Determined Contributions (INDC).[10]

Medium-range estimates of Arctic carbon emissions could result from moderate climate emission mitigation policies that keep global warming below 3°C (e.g., RCP4.5). This global warming level most closely matches country emissions reduction pledges made for the Paris Climate Agreement...

"The IPCC doesn't make projections about which of these scenarios is more likely, but other researchers and modellers can. The Australian Academy of Science, for instance, released a report last year stating that our current emissions trajectory had us headed for a 3°C warmer world, roughly in line with the middle scenario. Climate Action Tracker predicts 2.5 to 2.9°C of warming based on current policies and action, with pledges and government agreements taking this to 2.1°C.
