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

The document details the disproportionate impact of climate change on Central Africa, highlighting significant temperature increases, biodiversity loss, and economic decline. It emphasizes the critical need for transformative adaptation and increased climate finance to mitigate future risks to health, food security, and infrastructure.

• 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.
• Climate change has significantly reduced agricultural productivity in Africa by nearly 34% since the 1960s, a decline more severe than in any other global region.
• The region faces severe data constraints due to underinvestment in meteorological stations and research; between 1990 and 2019, Africa received only 3.8% of global climate research funding, with 78% of that allocated to institutions in North America and the EU.
• Future warming above 2°C poses a generalized risk of sudden and significant biodiversity loss in Central Africa, including threats to 36% of freshwater fish species in Africa.
• Climate change has caused substantial economic losses; between 1991 and 2010, the GDP per capita of African countries was on average 13.6% lower than it would have been without anthropogenic climate change.
• Health risks are projected to increase, with a warming of 2.5°C leading to 100 to 150 days per year of potentially lethal heat exposure in Central Africa.
• The Congo Basin's peatlands, which store an estimated 30.6 billion tonnes of carbon, are threatened by increasing aridity and changing rainfall patterns, which could lead to the release of greenhouse gases.
• Adaptation funding for Central Africa decreased between 2014 and 2018, and only 33% of the commitments made during that period were actually disbursed.
• Effective adaptation requires a combination of ecosystem-based solutions, gender-equitable approaches, and the integration of local and indigenous knowledge, such as practices used by farmers in Mount Oku and Mbaw in Cameroon.
• Urbanization in West, Central, and East Africa is occurring so rapidly that the area of urban land exposed to arid conditions is expected to increase by nearly 700% between 2000 and 2030.
