The impact of climate change on rainfall patterns in Ghana: A zoning adaptation strategy through developing agroforestry

Mohammed Suabir Zubairu

Abstract: As a developing country in Africa, the effect of climate change is one of the sufferings of Ghana. The effect is much felt in rainfall variability because of the country over reliance on rainfall for agriculture. Over the past forty years, historical analyses of the cropping systems in Ghana indicated that there has been a shift from cocoa based to maize based cropping system. The shift was as a result of decline in the yield of cocoa due to changing rainfall pattern, lack of agricultural diversification and reliance on the production of crops that are sensitive to climate change. Also, an area suitability analysis of cash crops shows that climate change also creates an avenue for the cultivation of crops in certain areas that are formerly not grown there. For instance, cashew cultivation will become more suitable in parts of the north and east. To ascertain the variability in the rainfall pattern due to climate change, rainfall time series from 1981 to 2018 from the National Aeronautics and Space Administration (NASA) satellite for seven meteorological stations selected from the ecological zones of Ghana were analyzed. There are decreasing rate of rainfall in some months and increasing rate in others as estimated by the Sen’s Test which clearly depicts variability in the rainfall pattern. As an agrobased country, to adapt to the current climatic condition, cashew agroforestry is suggested by this study because its growth will be suitable in the current and future condition because larger portion of the country has been justified to be suitable for its cultivation.
