Water is the most precious gift of the nature and is essential for sustenance of life.But human being forgetting its value. Inspite of use it human being is exploiting it. Specially in agriculture sector farmers are not caring its use. In india rice cultivation is increasing day by day. Its effect is that not only water is using many times more than other crops but also usage of electricity alsor increasing through Tubewells. India is facing the problem of scarcity of electricity. Solar energy could not introduce here due to high cost.
If we talk about air, It is one of most important component, which influences economic, agricultural and industrial growth of mankind.
Of all water on earth, 97.5% is salt water, and of the remaining 2.5% fresh water, some 70% is frozen in the polar icecaps. The other 30% is mostly present as soil moisture or lies in underground aquifers. In the end, less than 1% of the world's fresh water (or about 0.007% of all water on earth) is readily accessible for direct human uses (www.who.int).
India has only 4.2 percent of world’s fresh water resources to sustain 16 and 17 percent of world’s human and animal populations per capita annual average of 5,177 cubic meter in 1951, fresh water availability in India dropped to 1,820 cubic meter in 2001. In fact, it is predicted that by 2025, per capita annual average fresh water availability will be 1,340 cubic meter approximately.
Per capita availability of water less than 1700m3 is considered as ‘stress’ level beyond which water availability gets classified as scarcity level. Below this level, availability of water is considered a severe constraint on economic development and environment quality (GOI, PC, 2007-2012).
Punjab is endowed with rich water resources. Punjab was fortunate in having five perennial rivers. But after partition in 1947, Punjab was left with three perennial rivers, Ravi, Beas and Sutluj and one seasonal river Ghaggar. Besides this, three internationally important wetlands, two nationally important wetlands, several state wetlands, canals and drains, ponds and reservoirs exist in the state. So People of India whatever they are farmer or industrialist. Think about save water, Save energy and protect environment
