November 10, 1934: Arizona declares war against California at Parker Dam

From above, tiny green irrigation circles draw a narrow buffer along the 2,300-kilometer course of the Colorado River like the brush strokes of a zoomed-in pointillist painting. These vibrant green dots stand out against the buff and ochre hues of the desert palette, a testament to the river’s life-giving waters. Less obvious are the 6.4 billion cubic meters of water that flow, or are pumped, more than 390 kilometers from the Colorado’s gorge through tunnels and canals, up and down hills, to the agricultural and population centers of Southern California each year, and the additional 3.4 billion cubic meters that gurgle toward Phoenix and central Arizona annually.

Gaming the system in the Caspian Sea: Can game theory solve a decades-old dispute?

Water-rights disputes are never easy. Whether they are over pumping from aquifers shared among adjacent landowners, allocation of resources at the municipal, county or state level, or division of a river or lake shared between neighboring countries, there is an inevitable push and pull among stakeholders over who gets what and how much. In the end, resolutions tend to be compromises — often meted out by governing authorities — which, while not ideal from any one party’s standpoint, appeal to the desire of the group for stability over strife.

Caspian Sea: Negotiation Support System

To supplement their efforts at modeling the Caspian conflict using game theory and, potentially, to aid the five littoral countries as they continue to negotiate over how to govern and apportion the sea and its resources, Kaveh Madani, a civil engineer at the University of Central Florida, and his colleagues have developed a computer model dubbed the Caspian Sea Negotiation Support System (NSS).

Voices: Climate change and civil conflict: New clues from El Nino

In 2007, 11 retired admirals and generals from the U.S. armed forces published a report arguing that global climate changes represented a major threat to global security. That same year, U.N. Secretary-General Ban Ki-moon argued in a Washington Post op-ed that the ongoing Sudanese civil conflict was, in part, attributable to climatic changes. By combining new techniques from climate physics and econometrics, my colleagues and I have found evidence that there is some truth in these statements. Indeed, the global climate can influence the outbreak of civil wars.
