Abstract
Differences about fresh water rarely if ever lead to war between neighbouring nations. However, lack of agreement about equitable water use will sooner or later disrupt water management systems. Similarly, unless fresh water is managed sustainably by both nations, their social and economic development will lag, with ultimate effects on any peace agreement. This Viewpoint describes an existing proposal for joint approaches by Israel and Palestine to managing their transboundary water, as well as current unilateral actions by the two governments that work against equitable and sustainable water management.
