1,2 and 3
Statement 1 is correct .India ,exports water-intensive foodgrains like rice,cotton,sugar and soybean. Water "embedded" in crops is the water content of each crop and once the crop is exported ,it cannot be recovered. In 2010,India exported about 25cu km of water embedded in its agricultural exports.This is equivalen to the demand of nearly 13 million people. India was a net importer of water until around 1980s.
Statement 2 is correct. It has long been recognized that a key factor undermining the efficient use of water subsidies on power for agriculture that,apart from its benefits towards farmers ,incentivises wasteful use of water and hasten the decline of water tablets. Acoording to an analysis by National Aeronautics and Space Administration(NASA) ,India's water tables are declining at a rate of 0.3 metres per year.
Statement 3 is correct .Since Independence ,India has invested numerous resources on irrigation ,both public (canal irrigation) and private (tube wells).In both cases the water has been deployed via "flood" irrigation,which is an extremely inefficient use of water . Irrigation investments must shift to adopting technologies like sprinkler and drip irrigation and rainwater harvesting.
