The African countries of the Sahel stand to be among the most affected by climate change. To help mitigate its effects, Beza Tesfaye argues that the United States should partner with civil society groups and expand climate adaptation and financing efforts. One danger factor in the Sahel is an excessive dependence on livelihoods based on agriculture, which is susceptible to climate change. Overuse of land and water eventually depletes the availability of resources; food costs rise as food security diminishes and agricultural productivity falters owing to climatic unpredictability. Collective aggression is more likely as a result of this phenomena. Increased levels of deprivation and insecurity might result from these difficulties; local, national, regional, and global actions will determine how well Sahelian nations are able to handle these dangers.
