AB  - Climate change represents one of the most significant challenges confronting economic development in Africa during the twenty-first century. Although the continent contributes less than four percent of global greenhouse gas emissions, African countries remain among the most vulnerable to climate-induced shocks, including rising temperatures, prolonged droughts, flooding, desertification, biodiversity loss, and disruptions to agricultural productivity.
