Impacts Water

Water is one of Bhutan’s most abundant resources that supports agriculture, hydroelectric energy production, and tourism. Bhutan’s water resources are in glaciers, glacial and high altitude wetlands, rivers and river basins, and ground water reservoirs. Groundwater and reservoirs are considered to be limited to flat valleys, particularly in regions close to the Indian border. The country has water availability of 94,500m3 per capita per year; however, the majority of rivers are located in hard to reach areas and serve as the main source of irrigation and drinking water. Bhutan has an installed capacity of 3.76 GWh and potential to produce 30GWh (Bhutan Economic Development Policy, 2016). Bhutan’s reliance on hydropower for development and growth makes the country highly vulnerable to climate change impacts that can impact power generation and existing assets. Changes in river flow would have direct impacts on energy security and production by affecting energy generation, reducing water reserves, and exposing infrastructure to hazards such as flooding.
