- W3018840504 abstract "In India, spatial and temporal variation of precipitation has been boundless varying from 11000 mm to 90 mm. The average annual per capita water availability has declined from 5000 cubic meter in year 1950 to 1545 cubic meter in year 2011 and estimated to reduce further to 1341 and 1140 cubic meter in year 2025 and 2050, respectively. Agriculture sector, which provide 54.6% of total employment to growing population, alone consumes more than 90% of total groundwater draft in irrigation. Over the years, groundwater has become dominant source of irrigation due to its independent access and timely availability of water. This outrageous dependency on groundwater has led to depletion of water table in 64% district of the country between TE2002 and TE2016. With collective efforts of government at various levels, utilized irrigated potential including both surface and ground water has increased to 87 Mha while ultimate irrigation potential touched 140 Mha. In context of rapid depletion of water resources, there is need to increase water use efficiency. Efficient method, like microirrigation, can play pivotal role in management of irrigation water demand. Properly designed and managed drip and sprinkler irrigation system have irrigation efficiency about 90% and 70%, respectively contrast to surface irrigation method which have just about 40%. Recognizing the gravity of water scarcity in many part of the country, government has started formulating its water policy pivotal to micro irrigation. In year 2015, government has bundled all ongoing irrigation schemes into Pradhan Mantri Krishi Sinchayee Yojna (PMKSY) in which micro irrigation as an integral component. The successful adoption of water efficient technologies has two preconditions namely technical know-how and its accessibility through institutional support systems. Government has taken many initiatives to intensify outreach of efficient irrigation technology to farm." @default.
