Rainfall and Agriculture in Central West Africa since 1930

Sub-Saharan West African rainfall is highly variable and its influence on crops need to be assessed. This study examines rainfall variability and its effects on crops, societies, and economies. This analysis also investigates rainfall/ crop yield relationships. Additionally, comparisons are drawn with successive environmental policies. The results concluded that the main influence on agriculture is rainfall and so, crop yields revolve mainly around the occurrence/non-occurrence of rains. This study recommends that environmental policies should acknowledge the importance of seasonal rainfall forecasts and incorporates the climate aspects into agricultural productivity.
