In the interim, what may begin to ease the problem are the several new desalinization facilities to be constructed by Israel. By creating new water sources for Israelis, theoretically--in combination with efforts that have resulted in a decline in Israeli water consumption over the past month--more water will be available for distribution and in natural aquifers.
The desalinization facilities are also part of the solution to the problem of the dying Dead Sea. Significant water withdrawals from the Kinneret, or Sea of Galilee in northern Israel by Israelis, Jordanians and Palestinians, combined with a drought impacting the whole region are causing the Dead Sea which is fed by the Kinneret to shrink. This impacts not only a unique ecosystem, but also the many industries, including tourism, which rely on the Dead Sea. Environmental groups, such as Ecopeace have criticized a plan being discussed to pipe water from the Red Sea to the Dead one in order to save the latter. The project is fascinating in that it has Israelis and Jordanians cooperating with one another to find a solution, but as the critics point out, it's a proposal fraught with problems. The best solution remains the natural one. Let the Kinneret feed the Dead Sea and let the desalinization facilities do what they can to ease the pressure on it. As for the drought, well, if you're so inclined, pray for rain.
On a final, water related note, this article highlights the importance of water to the peacemaking situation and political dynamics and considerations in the region. In short, Syria has, apparently, seriously mismanaged its water resource and is, on a regular basis, being short changed on the water that Turkey allows to naturally flow across its border into Syria. This places Syria in a water crisis situation and naturally, they are looking at new sources for this water, the Golan Heights and the Kinneret amongst them. Rather than talk of war, discussions seem to be over how to share these resources peacefully. The problem the article points out is that there are no safeguards that Syria will not also mismanage water in the Kinneret, should it be given access, which would impact all other riparians of that basin. As seen under the Israel-Jordan peace treaty, however, even in hard times, the two states honour their agreements and share the water they both need. Maybe Syria can be trusted as well, but some sort of joint management system would need to be set up. If Syrians are as poor at water management as this article suggests, then they cannot be trusted; not because they have ill intent, but because despite their best efforts, they may simply have no idea what they're doing.
Another interesting point in this article is that Turkey, a country so eager to be the mediator between Syria and Israel is the one partially at fault for problems in Syria and so they have a national interest in seeing a deal struck which could ease the pressure on them to reduce their water consumption. Both Syria and Israel ought to be wary of this consideration and perhaps even allow another trusted mediator to work on that part of the deal. As always though, water will not be a point of friction between Syria and Israel, it will be a point for cooperation and confidence building. The universal need for water makes it too valuable to squabble over and risk losing.
