Developed countries are mostly located in the temperate or tepid latitudes, hence they have more precipitation. On the other hand, developing countries have mostly arid and semi-arid climates which they lack in the sufficient rainfall. Imbalance between water needs and its resources has been a crucial issue for these countries. It has been expected that by the year 2025, 34 countries most of them developing nations will experience water scarcity (2) (3). This situation is more critical in the North Africa and in the Middle East (4).
