Dangers of climate change: lack of water can lead to war

Water wars
Climate change leads to higher temperatures. Higher temperatures lead to melting glaciers, so snowmelt-based water supplies decrease. Climate change also leads to more irregular rainfalls rather than the more sustained and regularized patterns that make it easy to store and irrigate crops. In the Middle East and North Africa, the world's most water-stressed region, per capita water supplies were expected to halve by 2050 even in the absence of global climate change, having effects on an increasing population. The effects on agriculture will be unpredictable but unpleasant.
Water is basic. When there's not enough of it, people die. When there's not enough to keep crops properly irrigated, there's famine. So it's not a big shock that when water decreases, conflict over it increases. Or to put it more simply, a lack of water leads to war. Societies unable to adjust to the new challenges are left with two main options: fight or flee. The former strategy implies securing an increasing share of the diminishing resources -by force if necessary. Obviously, countries would prefer to talk in order to equitably share water access than to fight over such access. It's when talking fails that fighting begins.
As an example, Egypt depends on the Nile for almost its entire water supply. It's not surprising that Egypt has literally threatened to go to war to secure its access to water from the Nile. Egypt is not the only potential ignition point for conflict in the arid Middle East, where over 90 percent of fresh-water crosses international borders.
Countries should place policies that account for the fact that although water is renewable, it is not infinite. Policies can make existing water supplies sufficient, or they can destroy them. Aid donors can do a great deal to help resolve water conflicts. Political leaders must be involved. Water conflicts are solvable technically, but technical resolutions can only be put into place by political compacts.
