REDUCING AGRICULTRUAL WATER DEMAND IN LI BYA THROUGH IMPROVING WATER USE EFFICIENCY AND CROP WATER PRODUCTIVITY

摘要

The looming water crisis in Libya necessitates taking immediate action to reduce the agricultural water demand that consumes more than 80% of the total water supplies. The available information on water use efficiency reduced while maintaining the same, if not more, total agricultural production at national level. Crop water productivity, which is depressingly low , can be doubled through implementing several measures including: relocating agricultural crops among different hydroclimatic zones and growth seasons; crop selection based on comparative production advantages; realization of the maximum genetically determined crop yields; and several other measures of demand water management. There is an urgent need to establish the necessary institutional arrangements that can effectively formulate and implement these measures as guided by agricultural research and extension services involving all beneficiaries and stakeholders in the process.
