Rainfall water gathering is the key to preventing as much as raindrops from being wasted. The Yemeni government should have a clear strategy plan to construct dams to get in the way of water from flowing. It also should allocate in its budge an accurate amount to implement this strategy. For example, if we go back through the Yemen old history, we will find the most of civilizations have been dependent on the dam constructions, such as Marb’s dam which is mentioned in the Holly Quran. It is greatly easier and more effective to use surface water instead of drilling and pumping groundwater.
Developing the irrigation efficiency is also important technique. Most of Yemeni farmers still use the traditional irrigation system. Consequently, more than 60 percent of this system is lost due to outflows. However, the productivity of this system is only between 30-40 percent, which means a lot of water is lost. Developing this system, through use of better a new technology technique is affected. For instant, pips and sprinkler systems would directly reduce the percentage of wasting. Accordingly, improving systems will represent
