India receives about 4,000 cubic kilometers of rain annually, or about 1 million gallons of fresh water per person every year. However, the precipitation pattern in India varies dramatically across distance and over calendar months. Much of the precipitation in India, about 85%, is received during summer months through monsoons in the Himalayan catchments of the Ganges-Brahmaputra-Meghna (GBM) basin. The northeastern region of the country receives heavy precipitation, in comparison with the northwestern, western and southern parts. The uncertainty of the start date of the monsoons, sometimes marked by prolonged dry spells and fluctuations in seasonal and annual rainfall is a serious problem for the country. The nation sees cycles of drought years and flood years, with large parts of the west and south experiencing more deficits and large variations, resulting in immense hardship, particularly for the poorest farmers and rural populations. Lack of irrigation water regionally leads to crop failures and farmer suicides. Despite abundant rains during July–September, some regions in other seasons see shortages of drinking water. Some years, the problem temporarily becomes too much rainfall and weeks of havoc from floods. This excess-scarcity, regional disparity and flood-drought cycles have created the need for water resources management. Rivers inter-linking is one proposal to address that need. Due to global warming, fossil fuels use is discouraged and carbon neutral, clean, and renewable energy sources like solar and wind power are encouraged which are intermittent and variable types of electricity generation. Pumped storage hydroelectric power plants are needed to store the surplus electricity generated during daylight time by the solar power plants and supply the required electricity during the night hours. Water security, energy security, and food security can be achieved by interlinking rivers by envisaging multipurpose freshwater coastal reservoirs.
