Right you are Yogesh, agriculture should come first, since irrigation absorbs 2/3 of available fresh water. The simple answer to the problem is to reduce evaporation in hot and arid areas, which 50% of the water brought to the soil. Take a look at one the most promising technologies for this: http://guilspare.com This product reduces irrigation by 50% by coating soil particles to prevent evaporation to take place, while allowing air exchange in the soil. Another advantage of this is to allow the access to water to the plant at anytime (no more water stress for the plant and for the growers), while reducing the salt content by percolation effect (salt being brought down). Its price is paid back several times by the economy on water and by the increase of crop yield. Am afraid nobody understands this. How about you?

I am not the right person to comment on the product you mentioned, Laurent. The soil scientist and agronomy expert may like to comment.  However when we talk of saving water, we have to prioritize the areas, where efforts may bring better results. The agriculture sector utilize maximum water. If we grow crops, which utilise less water -sowing to harvesting, then water consumption can be reduced. There are two alternatives, one is growing rice , sugarcane and other high water consuming crops in much lesser areas and other is to discover/ invent new varieties of rice, sugarcane ,etc which consumes much less water.
