The main aim of this paper is to address the impact of irrigation water scarcity on the socio-economics of agricultural sector and the Jordanian food security. The rapid increase in Jordan population have placed unprecedented demand on water sources. The main findings of this paper were that decreasing water supply by 20 percent will be followed by a reduction in the total cultivated area by about 14 percent. This will lead to a decrease in the total net income generated by 15 percent. As a policy implication of this paper, it is suggested that irrigated land base must be maintained in good order to sustain relatively low food prices. New strategies for water development and management are urgently needed and to continue searching means and methods to increase water supply by increasing the investment in the irrigation sector, which can increase water supply and irrigation use efficiency.
