AbstractThe Okavango River Basin is a transboundary basin which serves as an important source of water resources for three riparian Southern African states, namely Angola, Botswana, and Namibia. If not properly managed, the Okavango River Basin is a potential source of conflict amongst the three countries. In order to reduce the likelihood of disputes among riparian states, the Governments of Angola, Botswana, and Namibia have signed and ratified an agreement establishing the institutional framework for the management of the shared water resources. This article discusses the legal aspects of the institutional arrangements in the Okavango River Basin. It highlights the importance of river basin organizations in the effective management of transboundary watercourses. This article concludes that the institutional arrangements between the riparian states with access to the Okavango River provide the framework for resolving possible disputes peacefully. Further, it concludes that these institutional arrangements promote co-operation over the management of the shared water resources.
