Water Adaptation in the Arab Region
Despite the dissimilarities between the countries (GDP, level of poverty, etc.), the Arab region has an arid to semi-arid climate in common. It is considered as one of the most arid zones in the world and most countries in the region are water stressed. The Food and Agriculture Organization’s (FAO) AQUASTAT Database of the year 2011 have shown that 16 out of 22 Arab countries had less than 1 000 m3 of annual renewable water resources per capita. Among these 16 countries, 13 had less than 500 m3 of annual renewable water resources per capita; a number that represents absolute water scarcity in these countries. With a high urbanization rate and population growth, the situation is expected to worsen, in 2001 it was predicted that the average annual renewable water resources would have fallen to 667 m3 per capita by 2025 Water resources in the Arab region are extremely rare. There are only a few major perennial rivers and lakes in the region, and some smaller rivers in the Maghreb Region. Countries with no surface flows of river count on rainfall; however, taking into account the aridity of these countries, most of the water is evaporated.
