اثر شحة الموارد المائية على الزراعه المروية في العراق

Abstract

The scarcity of water resources in Agricultural sector is very critical now. The irrigated agricultural sector in Iraq balled about (85%) from water resources that belongs to the agricultural sector because Iraq was the first among Arab countries in irrigated agriculture. In the same time there was decreasing in water amount supplying to Iraq from Tigris and Euphrates by the rate (1.5%), the decreasing in water amount in Tigris was  (3.2 %) , while the increasing in water amount in Euphrates record  annual average growth about (1.3 %) in period (1991-2008) ,  this decreasing influence on quality of two rivers water because the salt increasing in both of them . The receptor water rate belong to agriculture in this period was (47.35) milliard cubic meter yearly , while the total requirements of water to agricultural purposes was (29.88)  milliard cubic meter yearly in study period .The water lost rate was (17.47) milliard cubic meter yearly in (1990-2008).This indicate that the main cause of water scarcity in irrigated Agricultural Sector is non rational-classical methods of irrigation more than the decreasing of  receptor water rate belong to agriculture. According to that it was necessary for that reason to focus upon water quotes for crops and reducing water losing by using the modern irrigation methods .Thus we wanted from the department that responsible about this matter put the suitable polices for increasing the water supply and that suites to the increasing of water demand whether it is for the agricultural irrigation or for the other purposes or other sectors   .
