www.fao.orgOverall, this can lead to wasteful water use, over-abstraction of groundwater, and low field application efficiency (Shah and Kishore 2012, FAO 2017). In some cases, farmers were selling water to their neighbours at a profit, increasing the overall water withdrawals. It is therefore crucial to complement SPIS technology with
Important Information for Private Well Owners
www.doh.wa.gov• Even if water use falls under the permit exemption criteria, you may still apply for a water right permit from Ecology. • Although exempt groundwater withdrawals do not require a water right, they are subject to state water law. Ecology may place conditions on groundwater withdrawals when they interfere with prior, “senior” water rights.
IDENTIFICATION OF GROUND WATER POTENTIAL ZONES …
troindia.inGround water potential zones are the zones which mark the availability of groundwater. Identification of potential groundwater zones could aid in proper development and utiliza tion of both groundwater and surface water resources for eliminating water scarcity and thereby improving the irrigation practices and agricultural income for
The Carbon Footprint of Water - Chicago State University
www.csu.edu• If groundwater levels across the United States were to drop an average of 10 feet due to unsustainable water withdrawals, energy demands for agricultural groundwater pumping would increase by approximately 1.1 million MWh per year. Assuming pumping energy is derived from the U.S. electrical grid, associated carbon dioxide emissions would be

The earlier estimates focus on the estima-tion of blue water withdrawal (Gleick, 1993; Alcamo et al., 2007) and irrigation water requirements (D¨oll and Siebert, 2002). More recently, a few studies have separated global water consumption for crop production into green ...
