Instead of planting crops or fruit trees that do not require lot of water, big portion of the farmlands are the total opposite, planted with highly demanding crops and fruit trees for water. Because of that, most of the groundwater has been already used, and that has been the largest source of freshwater in the region. The pollution of the rivers is also a big problem, because making the water not suitable for drinking, with having such small reserves, can easily lead to a disaster.
