Israel: No Claim On Litani Waters
Quality information on the Rivers Of The Fertile Cresent tends to be dense and technical, but there are occasional bits of political dynamite, such as this quote. The Fig. 1 mentioned is the above map of the Jordan & Litani river basins.
On the other hand, it is worthy to note that while analyzing the Lebanese part of the Jordan River Basin, no connection between the Litani River Basin and the Jordan River Basin was found in terms of surface flow, even though both basins lie close to each other (Fig. 1). The Litani basin was found to lie entirely in Lebanon. This result removes any ambiguity pertaining to the inclusion of the waters of the Litani River in any future water allocation scheme for the Jordan River Basin. As it was mentioned in the Johnston Plan and the Israeli “Cotton Plan”, some Israeli negotiators wished to include the Litani River in the Jordan River Basin plan (Amery 1998). Today, the inclusion of the Litani River is still present in the opinion of some politicians but these arguments are not credible since hydrological connections between the Litani and Jordan River Basin have not been proven (Medzini and Wolf 2004; Zeitoun et al. 2012).
Water has been a pressing concern for the region, driving the dispute between Arabs and Jews since Israel’s inception. This quote from a 1982 Christian Science monitor article reveals the entanglement of aquifers and state boundaries.
Two aquifers provide almost all of the groundwater for Northern and Central Israel, both arising in the West Bank. The shallower sandstone aquifer is recharged partly from runoff and percolation of rainwater falling on the former Jordanian lands. The deeper and more copious limestone aquifer is recharged largely or, possibly, entirely by rainwater from the West Bank.
The Litani River of Lebanon from 1993 is the best overview I have found regarding this situation and it notes interest in transferring a portion of the flow of the Litani to the south has existed for over a century. The web page looks to be the sort of thing that might vanish, so I preserved a copy of the content in Scribd.
