In Israil, for example drip irrigation startup save tons of water in agricultural side. It is micro irrigation system, and it has potential to save water and nutricient by allowing water to drip slowly the root of plant and in this way it also minimaze the evapuraton rate. To conclude, although the the growth of population and errenous usage of freshwater can cause shortage, the involvement of every person might be effective by taking strict actions to solve this issue.
