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).

Energy storage brings a renewable energy future one step closer

Renewable energy sources promise to address many of the energy challenges facing society: They derive power from inexhaustible supplies of sunlight and wind and have the capability to meet a substantial portion of global electricity demands without adding greenhouse gases to the atmosphere. However, renewable power supplies must first overcome one inherent drawback: variability.

Think differently: renewable hydrogen generation

Most of the existing solutions for renewable energy storage represent riffs on our current energy infrastructure. They are either inherent to existing fuel sources (concentrated solar power), or linked directly to the grid (flywheels, pumped storage and compressed air energy storage). But what if the future looks radically different from today, as history has often shown it can? What if the future of energy is based on hydrogen produced by renewable energy sources?

Writing on the Rocks

Visitors to White Sands should plan on making a slight detour to the Three Rivers Petroglyph Site, an hour’s drive from the national monument. This scenic basalt ridge between White Sands and the White Mountains contains one of the greatest concentrations of petroglyphs anywhere in the Southwest. More than 21,000 petroglyphs of geometric and abstract shapes, faces and animals were etched into the dark rocks by the Jornada Mogollon people, who lived in this area between A.D. 1000 and 1400.

Getting There and Getting Around New Mexico

Missile testing

White Sands National Monument is surrounded by military installations, with the White Sands Missile Range to the north and Holloman Air Force Base to the east. Occasionally, the national monument and U.S. Highway 70 between Alamogordo and Las Cruces are closed due to missile testing.

Travels in Geology: Exotic dunes and atomic bombs in New Mexico's White Sands

The Desert Southwest is famous for out-of-this-world landscapes — some places look like the moon, others like Mars — but New Mexico’s White Sands National Monument, at the very northern end of the Chihuahuan Desert, offers an otherworldly backdrop like no other

A hurricane by any other name: How Sandy changed the way we issue storm warnings

As last year's Superstorm Sandy bore down on the Northeast, storm watchers could tell it would be worse than anything seen in decades, but the storm warnings were missed by many. One disconnect came from strict protocols about how federal agencies issue warnings. Since the devastating storm, federal officials have been revising their protocols to avoid a repeat situation. Will it be enough?

Building resource corridors in Afghanistan: A solution to an interminable war?

Afghanistan has been ravaged by decades-long conflicts that have left it economically depressed, but the country also holds a potentially huge natural resource base. Some estimates have put the value of the resources — copper, gold, coal, oil, gas, industrial minerals, rare earth minerals and more — between $1 trillion and $3 trillion.
