However, agriculture in competition with other sectors will face increasing problems of water quantity and quality considering the limited conventional water resources and growing future requirements. If the amount of water that is added to the soil is less than the amount requires by the crop, reduction in growth occurs.
Most plants have critical periods of growth during which a lack of water is the most damaging.
While in Israel and Jordan about 1275 MCM and 652 MCM are used for agriculture in both countries respectively. Therefore, irrigation management is considered to be a priority under the current condition. As discussed earlier the available water for irrigation is about 93 MCM which is not enough for current level of development. Soil agricultural ponds with plastic covers are the most dominant in the West Bank. Rainfall harvesting by plastic houses is another way used by farmers to over come water shortage.
