Abstract
Managing trans-boundary water and its watershed areas is a challenging task. The riparian countries sharing the boundary may have different economic and national goals that can dictate the pressures exerted on water bodies and their catchments areas. The pressure will have dire consequences on the environment, the climate and the sustainability of the Volta River. This paper seeks to apply the Driving Forces-Pressure-State-Impact-Response (DPSIR) framework as a model to ascertain the driving forces and their impacts on the Black and the White sub-basins of the Volta River. The research was carried out through desk study of literature, reports and policies on the Volta basin as well as information from international bodies such as World Bank, United Nations, and European Union among others. The DPSIR framework thus established the state of the ecosystem, pressure exerted, impact and the responses to provide scientific basis for decision-making and address the impacts on the Volta River. The DPSIR framework was focused on Ghana and Burkina Faso due to their large share of the basin. Burkina Faso's share of the Volta basin area is 43 %, whereas, that of Ghana is 41.6 %. The use of DPSIR model will help stakeholders and policy makers in proper decision making. It was therefore recommended that there should be policy regulations to reduce the impact on the environment.
