The greatest game changer in solving the water crisis would be to reduce irrigation water in agriculture which is by far the largest consumer of freshwater. controlling irrigation water with drip irigation is a means of reducing drainge and run-off water losses. However evaporation loss is the largest segment of non-productive irrigation water in agriculture. It is also a greenhouse gas which impacts climate change by heating the troposphere.

The next game changer is to cycle saline water in areas which have limited accessibility to freshwater for agriculture.
