Explanation:
Water resources are natural resources of water that are potentially useful. Uses of water include agricultural, industrial, household, recreational and environmental activities. All living things require water to grow and reproduce.
A graphical distribution of the locations of water on Earth. Only 3% of the Earth's water is fresh water. Most of it is in icecaps and glaciers (69%) and groundwater (30%), while all lakes, rivers and swamps combined only account for a small fraction (0.3%) of the Earth's total freshwater reserves.
97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps.[1] The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air.
Fresh water is a renewable resource, yet the world's supply of groundwater is steadily decreasing, with depletion occurring most prominently in Asia, South America and North America, although it is still unclear how much natural renewal balances this usage, and whether ecosystems are threatened.The framework for allocating water resources
The Central Pollution Control Board (CPCB) along with the State Boards monitor water quality at 507 stations. Some of the legislations passed by government include water (Prevention and Control of Pollution) Act, 1974, Water Cess Act, 1977, Environment Protection Act, 1986 and National Water Policy, 2002. Ganga Manthan dialogue was initiated recently, to discuss measures to check pollution of Ganga water. Placing portable toilets and small scale water treatment plants along the river can go a long way in halting pollution
Other than these, efforts of NGOs and citizens have also counted in the cleaning of lakes such as Puttenahalli lake, Dal lake, Agara lake, Rankala lake etc. Maintenance of water quality and water conservation are the needs of the hour. Villages’can collaborate to form watersheds, so that wells and other water reservoirs can be recharged with water. Ralegan Siddhi is a village in Maharashtra which successfully implemented this approach. Rainwater harvesting has been made mandatory in Tamil Nadu.
India’s water resources are in ample amount, but what is available freely, shouldn’t be wasted. Let us be more responsible and emulate successful models like that of Ralegan Siddhi in every part of India.
