Rakitskaya, Katsiaryna
The water-energy-food nexus approach, where closely-connected water, energy and food sectors and their interlinkages are considered together, can be useful to fully understand and address impediments to these sectors’ security and their sustainable development. This study is a review of the current status of the water-energy-food nexus in India, main interlinkages and main challenges to the sustainable development of the nexus. One of the main interlinkages is irrigation in the water-food connection, as the majority of water withdrawn in India is used for agriculture. The water-energy interlinkages are crucial not only in the context of hydropower generation, but also due to the large amounts of water being used for cooling of fossil fuel and nuclear power plants. The pressure on water resources is exacerbated by rainfall reductions in India caused by climate change. Social and economic factors, such as population growth, change in food habits, economic growth and technological advances, further increase the demand for water, energy and food. This all poses significant challenges related to water availability and, as a result, water, food and energy security in India.
