پیامدهای امنیتی غذا از جایگزینی مواد غذایی اصلی در غرب آفریقا ساحل

Our simulation results suggest that regional trade in maize, yams and cassava-based prepared foods like gari and attieké could fill over one-third of the consumption shortfall resulting from a major drought in the Sahel. Increasing substitutability across starchy staples, for example through expansion of maize, cassava and sorghum-based convenience foods, would further moderate consumption pressure by expanding the array of food alternatives and hence supply responses available during periods of stress.
