N2 - Pakistan is a resource-constrained country facing severe power shortages. To address the power demand-supply gap, Pakistan has increased its use of fossil fuel energy sources for power generation. To support a lower carbon power supply Pakistan needs renewable energy sources such as hydropower. However, most of the water for irrigation and power generation in the country is derived from a watershed in a disputed territory shared between India and Pakistan. Construction of hydroelectric dams over transboundary rivers have led to concerns regarding their ecological impacts. In this paper, we evaluated the sustainability of the Bursar Hydroelectric Project, proposed on such a transboundary river.
