Drought and global conflict

Here's an article describing how drought contributed to the ills in Syria.

An excerpt:

Syria has been convulsed by civil war since climate change came to Syria with a vengeance. Drought devastated the country from 2006 to 2011. Rainfall in most of the country fell below eight inches (20 cm) a year, the absolute minimum needed to sustain un-irrigated farming. Desperate for water, farmers began to tap aquifers with tens of thousands of new well. But, as they did, the water table quickly dropped to a level below which their pumps could lift it. 
In some areas, all agriculture ceased. In others crop failures reached 75%. And generally as much as 85% of livestock died of thirst or hunger. Hundreds of thousands of Syria’s farmers gave up, abandoned their farms and fled to the cities and towns in search of almost non-existent jobs and severely short food supplies. Outside observers including UN experts estimated that between 2 and 3 million of Syria’s 10 million rural inhabitants were reduced to “extreme poverty.”

The domestic Syrian refugees immediately found that they had to compete not only with one another for scarce food, water and jobs, but also with the already existing foreign refugee population. Syria already was a refuge for quarter of a million Palestinians and about a hundred thousand people who had fled the war and occupation of Iraq. Formerly prosperous farmers were lucky to get jobs as hawkers or street sweepers. And in the desperation of the times, hostilities erupted among groups that were competing just to survive.
