Impacts, options d’adaptation et domaines d’investissement pour une Afrique centrale résiliente au changement climatique

This fact sheet, published by the Climate and Development Knowledge Network in 2022, synthesizes findings from the IPCC's Sixth Assessment Report regarding the impacts of climate change in Central Africa. It details observed temperature and precipitation trends, future projections for health and biodiversity, and the economic consequences of warming. The document also outlines adaptation strategies, such as nature-based solutions and integrated water management, while highlighting critical gaps in climate research funding and data collection for the region.

• Central Africa has experienced warming that exceeds the global average, with annual and seasonal mean temperatures increasing by 0.75°C to 1.2°C since 1960.
• Future projections indicate that at 2°C and 3°C of warming, Central Africa's average annual surface temperatures will remain higher than the global average. Extreme heat will increase, with the number of days above 35°C rising from 61–63 days (1995–2014) to 14–27 additional days at 2°C, and 33–59 additional days at 3°C.
• Climate change has significantly reduced agricultural productivity in Africa by nearly 34% since the 1960s, more than in any other global region. Specifically, between 1974 and 2008, maize and wheat yields in sub-Saharan Africa decreased by 5.8% and 2.3% respectively.
• The Congo Basin's Central Cuvette peatlands, which store an estimated 30.6 billion tonnes of carbon, are threatened by increasing aridity and changing rainfall patterns; drying would release greenhouse gases instead of trapping them.
• Health risks are projected to increase, with malaria endemic levels expected to rise by 2050 under a medium warming scenario. However, at very high warming levels (above 2.5°C by 2050 or 4°C by 2100), some parts of southern and central Africa may become too hot for malaria transmission.
• Biodiversity in Central Africa faces severe risks; above 2°C of warming, the risk of sudden and significant biodiversity loss becomes widespread. At 1.5°C, over 10% of species at a site are threatened with local extinction across more than 90% of the land area.
• Adaptation options for the region include nature-based solutions, the use of drought-tolerant crop and livestock varieties, and integrated water management at the river basin level to balance water, energy, and food needs.
• There is a critical lack of climate data and funding for research in Africa. From 1990 to 2019, Africa received only 3.8% of global climatological research funding, and of that, only 14.5% was allocated to African institutions.
• Financial commitments for adaptation in Central Africa decreased between 2014 and 2018, and only 33% of those commitments were actually disbursed.
