The impact of climate change on the agricultural sector within the Volta Basin in Ghana

Abstract

The negative effects of climate change on crop production in Sub-Saharan Africa are pronounced, given the high dependence on rain fed agriculture in the region. This study analysed decision making by farmers under risk and uncertainty due to climatic change, using the Multi-Level Analysis Tool for the Agricultural sector (MATA) model. The main objective of the study was to find out the impact of climate change on cropping activities and agricultural income. The results indicated a decrease in water supply leading to changes in the composition and pattern of crop activities, reduced crop yields and smaller incomes for farmers. Reforms in water management policies and investments are suggested to improve water usage efficiency and to expand irrigation to deal with climate change.
