Water availability, management and use are crucial factors when it comes to maintaining modern populations in the arid and semi-arid environments that dominate much of India. Today, large parts of India are intensively farmed, and the large-scale mono-cropping of water intensive crops like winter (wheat) and summer (rice) crops is causing extreme water depletion. In combination, these factors are creating an acute risk to food security in the most populated country on the planet.
