I think that three factors are coming over and over. 1. Global warming 2. Population growth, and ecosystem reduction 3. It seems that underground waterways are experiencing some period of fluctuation due to recent crustal deformation. It has also been demonstrated in recent research that the continent was also under the lake. There is also the possibility that the idea of the angle etc. will be ruined unless factor 3 and the way of thinking are considered either. You should also consider the path of the underground waterway I am sorry to add a sudden question. 私は3つの要因が重なり遇っていると思います。 1.温暖化 2.人口の増殖、及び生態系の減少 3.此処近年の地殻変動で地下水路が何らかの変動期に喫していると思われます。 以前に湖の下にも大陸が在ったこと近年の調査でも実証されています。 ３番の要素も考え方も考慮しないと折角のアイデアなどが台無しになる可能性もあります。地下水脈の経路も視野に入れるべではないでしょうか 唐突な質問を加えて申し訳ないです

Mr Kawamura, thank you for sharing your thoughts.

Israel and Middle East in general have been experiencing serious droughts for many years. Provided that Middle East, including Yemen, the United Arab Emirates, Saudi Arabia, and Iraq,  in general is often understood to be arid desert climate. On top of that unique climate condition, climate fluctuation (climate change) escalated the severity of the drought beyond these nations, in addition to inadequate water supply / agricultural practice. 

People and generally farmers are not educated in farming , especially watering technique such as the use of irrigation using an advanced device / equipment.  Please, if you get a chance,　watch the Clip on  Iran Water Crisis (Video). Being equipped with such tech/knowledge makes a huge difference in reduction of water use to grow food. 

Yes, population growth is a factor that significantly affected how water is used, as well as the food production. 

※　When one says to use desal, there are several things you can assume:  Running out of other options - meaning groundwater (aquifers are already exploited or dried or collapsed to a point of no return - unless huge water flows into the area, which is unlikely due to the desert climate. ) Aquifers are fossil water that are flowing underground for millions of years. We arent going to fill that up with just one rain or one monsoon season. 

Geological time scale is typically in millions years. It takes that LONG TIME to produce fossil water. So far, humans have abused such seemingly free water body, then realize its value when it is vanishing. 

※ :  Desalination is usually the last resort in many cases, partly because it is expensive to build and operate, and also costly to the environment. The Middle East is generally in a dire situation, when it comes to water resources. Aquifers diminishing and not returning or without any quick fix.   It is important to note that the environmental conditions are, once destroyed, irreversible in its damages. All you can is to mitigate negative impacts. And people just dont get it until they lose it.  Taking water for granted means exactly this. What is worse is that people who need most water is the farmers and agriculture people - who are often not educated enough to seek new tech or knowledge, to do the mitigation "properly" "adequately".
