Abstract
That most of the Arabian Peninsula is located within the belt dry and semi-arid of the world, with high rates of evaporation and transpiration due to high temperatures and lack of precipitation is rain, which is volatile and irregular in distribution, and a large quantity of it be wasted through evaporation note that the rate of 15% of water from rainfall for use in irrigation of some crops and increase the level of groundwater, and evaporation rates exceed rates of rainfall about (35 to 100 times) as they reach those rates in the interior to about 4759 mm per year and to about 3162 mm per year in areas coastal and this is something that leads to the impossibility of achieving the balance of water or a water shortage suffered by these countries and this in turn led to the formation of food deficit and to the transitions and political pressure, many displays of national security of those States to vibration and especially that 90% of foodstuffs are imported from abroad and this is prompting these countries to move towards the exploitation of ground water and desalination of sea water and if what has been achieved piece, it may lead to resolving the part of the problem of water scarcity and reduce risks at the moment in order to satisfy part of the basic requirements and daily needs urgent, as have these states and Diane and Seoul are in their territory which are of potential water to be reckoned with tens of billions of cubic meters and is important to make use of them in the construction of dams and reservoirs and to hold the water and converted to agricultural land for the purpose of food production and groundwater recharge note that the groundwater constitute the main source of economic life and social and one of the sources of traditional generic water resources of surface and form the backbone of which will depend upon agricultural production and that 85% of that water goes to cover the need for the agricultural, the spectrum of the fact that agriculture using traditional methods that deliberately flooded the crops with water which is a big waste water and most of this, the irrigation per hectare of agricultural land needs to be more than 37 thousand m 3 of water in the countries of the Arabian Peninsula, and particularly in Yemen, while the need irrigation per hectare in dry and semi-arid than 10000 m 3 to 13000 m 3 of water and the resulting to the waste of water resources, while the operations of modern irrigation and particularly spray irrigation and drip and piped phones which reduces Aldaúat water by between 30 to 55% in addition to being works to preserve the fertility of the soil and protect it from the phenomenon of salinization and thereby increase its production of agricultural crops, and the over-the continuous consumption of ground water leads to the decrease in the levels and deterioration in quality so that led to that the rates of withdrawals have exceeded the rates of feeding in some locations and that what exploits are currently about (6) Milirm 3 Comparison of rate of fed, amounting to about 4.7 Milirm 3, resulting in a water deficit is estimated around $ 1.3 Milirm 3 which constitutes a heavy burden on scarce resources, traditional water has therefore adopted to meet the requirements of water desalination of sea water on the Persian Gulf and Red Sea, which accounts for about 60% of the potential of desalination in the world and with that water has its specificity it does not recognize political borders and geographical and movements are subject to natural factors discussed Vmsderha rain, which is the product of the hydrologic cycle, which distinguishes him any good again, and this is something that leads to disputes between neighbors about sharing its share of water as it gets Now between the Kingdom of Saudi Arabia and its neighbors, the GCC countries, Jordan and the face of this problem requires the agreements as a percentage of the rivers of international agreements that include a solution to the problems of the border first.
