A synoptic view on water and its sustainability in the 21^st century

Water, the gift of nature, performs manifold functions. Water is the breathing source for all creatures as it gives hydrogen and oxygen. It forms the world's streams, lakes, oceans and rain. Water is supplied from as many as 14 sources. Saline water accounts for 94.92%, but ground water forms only 1.66%. The demand for water is ever an increasing phenomenon, while it is in short supply. Fresh water is not evenly distributed among the nations and the same holds good within different region in the country. In a country like India, a minimum of 85 litres per day per person is required for a healthy living. India aims at giving 70 litres of water per capita per day within the household premises or at a distance of not more than 50m by 2022. The demand for water gives raise to water disputes both internationally and nationally. The short supply of water can be tackled through six fold strategies involving individuals, local body's, officials and governments.
