Multipurpose dams have been able to provide outputs related to all three nexus security issues. In Yunnan Province, China, the cascade of dams on the Lancang River (Upper Mekong Basin) provides electricity as the key driver and, in addition, economic growth, with the aim of improving the province’s status as second to last in terms of GDP per capita. The associated benefits include flood control, irrigation and water supply. In the Indus basin, better regulatory control of river flow and the use of groundwater supplements to irrigation water have resulted in substantial increases in agricultural productivity and an end to the famines of previous times. Hydropower outputs from the basin have increased electrification of industries, irrigation systems and villages, increasing the number of electricity consumers six-fold. In the Niger Basin, three dams have been planned and commissioned for construction to provide hydroelectricity. The increased water flow, particularly in the dry season, will enable two farming seasons and improved navigation. The expected results up to 2027 include a fivefold increase in the area of irrigated land and number of jobs created and substantial improvement in self sufficiency for rice.
