Cooperation in transboundary water sharing under climate change

As multiple countries share a river, the likelihood of a water resource conflict from climate change could be higher between countries. This paper demonstrates how countries can cooperate in transboundary water sharing in a sustainable way, given the
impacts of climate change. It illustrate the case of water sharing of the Volta River between the upstream and downstream country, Burkina Faso and Ghana respectively, where the latter country faces a tradeoff of water use between agriculture in the north and production of hydro energy in the south. The results indicate that during cooperation, Ghana will have an opportunity to increase its water abstraction for agriculture, which has remained largely restricted. It also find that the equilibrium strategies in the long run steady state distribution are stable even with increasing variances of water flow.
