  • CONSERVATION OF WATER Water conservation encompasses the policies, strategies and activities to manage fresh water as a sustainable resource to protect the water environment and to meet current and future human demand. Population, household size and growth and affluence all affect how much water is used. Factors such as climate change will increase pressures on natural water resources especially in manufacturing and agricultural irrigation. Some researchers have suggested that water conservation efforts should be primarily directed at farmers, in light of the fact that crop irrigation accounts for 70% of the world's fresh water use.[10] The agricultural sector of most countries is important both economically and politically, and water subsidies are common. Conservation advocates have urged removal of all subsidies to force farmers to grow more water-efficient crops and adopt less wasteful irrigation techniques.
  • WATERSHED MANAGEMENT What is watershed management? Watersheds can be defined as geo-hydrological unit draining to a common point by a system of drains.All lands on earth are a part of one watershed or another.Watershed is thus the land and water area,which contributes runoff to a common point. For example,the watershed of a lake would include not only the streams entering that lake but also the land area that drains into those streams and eventually the lake.
  • RAINWATER HARVESTING • It is a type of water harvesting system. • It can be defined as a system of collection and concentration of rain water and its runoff and its productive use for:a)Irrigation of annual crops,pastures and trees. b)Domestic and livestock consumption. c)Groundwater recharge.
  • Need For Rainwater Harvesting • Major parts of our country have been facing continous failure of monsoon and concequent deficit of rainfall over the last few years. • Also,due to ever increasing population of India,the use of groundwater has increased drastically leading to constant depletion of groundwater level causing the wells and tube wells to dry up. • In some place,excessive heat waves during summer create a situation similar to drought. • It is imperative to take adequate measures to meet the drinking water needs of the people in the country besides irrigation anddomestic needs. • Out of 8760 hours in a year,most of the rain in India falls in just 100 hours.

  • POLITICAL DEVELOPMENT MOVEMENTS IN DELHI REALATED TO WATER
  • WATER MOVEMENTS IN DELHI Delhi lies next to the desert of Rajasthan and close to the foothills of the Himalayas. The desert gives Delhi its dry climate, while the Himalayas act as a cloud barrier and lead to the 611.8 mm of annual rainfall in Delhi. Growth in private and industrial consumption has put pressure on resources such as water. While private groundwater extraction is illegal, it is rampant in the city. Both private and government companies are running bottled water plants using illegal groundwater.
  • WHAT WERE THE PROBLEMS? Large dams such as Tehri have been controversial, and several peoples’ movements have challenged their benefits on a national and international level. According to The Indian National Trust For Art and Cultural Heritage, 100,000 people were displaced by the Tehri dam. There is an increase in population which results in higher consumption of water. Delhi is an old city with a rich history of water management. But Delhi’s river is dead, and water governance is corrupt and inaccessible. Those with less are subjected to longer queues for water; children skip school and women face severe safety and sanitation issues. Thus, the task facing Delhi’s civil society and the government is enormous
  • HOW CAN THEY BE SOLVED? The Delhi government has attempted privatization of the city’s water supply since 2005. While a fierce peoples’ campaign defeated privatization efforts in 2005, the Delhi Jal Board has recently handed over parts of its water distribution and monitoring duties in South Delhi (the neighborhoods of Malviya Nagar and Vasant Vihar) to a private company affiliated with the Tata Group. A clerk with the Delhi Jal Board (DJB) explained that while the decision to privatize has been announced recently, the DJB has been raising water tariffs gradually over the years to prepare for handing distribution operations to Tata, as DJB did in 2012.The campaign to stop the privatization of water in Delhi in 2005 was initiated by Parivartan, an NGO run by Arvind Kejrival (who is currently bringing a new party into India’s politics). The movement was large, with Resident Welfare Associations playing a big part in the process.
