Sub-Saharan Africa is facing an unprecedented health and economic crisis that threatens to throw the region off its stride, reversing the encouraging development progress of recent years. Furthermore, by exacting a heavy human toll, upending livelihoods, and damaging business and government balance sheets, the crisis threatens to retard the region’s growth prospects in the years to come. Previous crises tended to impact affect countries in the region differentially, but no country will be spared this time.
Mitigation and adaptation measures overlap in some cases. For example, preserving and expanding the Congolese rainforest (one-quarter of the world’s remaining tropical forests) would remove carbon dioxide from the atmosphere. At the same time, the forest reduces exposure and vulnerability to climate change by regulating water (for example, forestcoverincreasesrainwaterinfiltration and replenishes streams), reducing erosion, and allowing the development of forest products that can be alternative sources of income for farmers hurt by climate change ( WRI 2011
