Zero-sum thinking emerges when people conceive of water as a fixed resource – one provided by nature in a given quantity that is either static or diminishing. Based on these assumptions, diplomats often focus on what share of the existing water will be given to each entity. Negotiations of this type typically involve decision makers who are political leaders focused on preserving sovereignty and maintaining state security. They are often unprepared to think about improving the overall efficiency of water use, which, in effect, can “create” more water.
