About the 2023 Annual Meetings


Climate-induced shocks represent one of the biggest threats to Africa’s socio-development prospects. All recent climate projections unanimously point to the fact that Africa will remain one of the most hard-hit continents by increased global warming. In the absence of ambitious climatechange policies, it is estimated that Africa could lose between 2% and 12% of GDP by 2100 depending on global warming scenarios, compared to a loss of less than 1% for the United States, European Union, and United Kingdom or between 1% and 5% for China1. Further, the Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC)2 warned that by 2030, 108–116 million people in Africa will be exposed to sea level rise (compared to 54 million in 2000), and this number could increase to 190–245 million by 2060. With a 1.7°C global warming scenario by 2050, it is estimated that 17–40 million people could migrate internally in sub-Saharan Africa, and up to 56–86 million for a 2.5°C global warming scenario, owing to water stress, reduced crop productivity, and sea level rise.
