Thomas Homer-Dixon argues during this sobering e-book that those environmental scarcities could have profound social consequences--contributing to insurrections, ethnic clashes, city unrest, and other kinds of civil violence, particularly within the constructing international. Homer-Dixon synthesizes paintings from quite a lot of overseas learn initiatives to improve an in depth version of the resources of environmental shortage. He refers to water shortages in China, inhabitants development in sub-Saharan Africa, and land distribution in Mexico, for instance, to teach that scarcities stem from the degradation and depletion of renewable assets, the elevated call for for those assets, and/or their unequal distribution. He indicates that those scarcities can result in deepened poverty, large-scale migrations, sharpened social cleavages, and weakened associations. And he describes the categories of violence which can end result from those social results, arguing that conflicts in Chiapas, Mexico and ongoing turmoil in lots of African and Asian international locations, for example, are already partially a end result of shortage. Homer-Dixon is cautious to indicate that the results of environmental shortage are oblique and act together with different social, political, and financial stresses. He additionally recognizes that human ingenuity can lessen the chance of clash, relatively in international locations with effective markets, able states, and an informed population. yet he argues that the violent effects of shortage shouldn't be underestimated--especially while approximately part the world's inhabitants relies at once on neighborhood renewables for his or her day by day health. within the subsequent many years, he writes, transforming into scarcities will impact billions of individuals with unparalleled severity and at an remarkable scale and speed. truly written and forcefully argued, this booklet turns into the traditional paintings at the advanced courting among environmental scarcities and human violence.

In Haiti, forest and soil loss has worsened a persistent economic crisis that generates strife and periodic waves of boat people. And land shortages in Bangladesh, exacerbated by fast population growth, have prompted millions of people to migrate to India—an influx that has, in turn, caused ethnic strife in the state of Assam. Close study of such cases shows that severe environmental scarcity can constrain local food production, aggravate poverty of marginal groups, spur large migrations, enrich elites that capture resources, deepen divisions among social groups, and undermine a state’s moral authority and capacity to govern.

In the Jordan River basin, Israel’s critical dependence on groundwater flowing out of the West Bank—a dependence made acute by an increasing Israeli population and salinization of aquifers along the Mediterranean coast—has encouraged Israel to restrict groundwater withdrawals on the West Bank during the occupation. These restrictions have been far more severe for Palestinians than for Israeli settlers. They have contributed to the rapid decline in Palestinian agriculture in the region, to the dependence of Palestinians on 16 CHAPTER 2 day labor within Israel and, ultimately, to rising frustrations in the Palestinian community.

The conjunction of this in-migration with high fertility rates is causing city populations to grow at an astonishing 4 to 5 percent a year, producing fierce competition—and often violence— among ethnic groups over land, basic services, and political and economic power. This turmoil exacts a great toll on the national economy. In Chiapas, Mexico, Zapatista insurgents rose against land scarcity and insecure land tenure caused by ancient inequalities in land distribution, by rapid population growth among groups with the least land, and by changes in laws governing land access.
