Learning from a River’s History to Prepare for the Future

Researchers from eight universities, including Columbia University, are using tree ring and glacier analysis to reconstruct the climate history of the Missouri River Basin in order to give policymakers and water managers better decision-making tools to manage the river.

Mekong Delta and Three Gorges Dam: World’s First Climate Change Resettlements?

Many resettlers are economically better off, but the dislocations remain significant, especially for older resettlers, who have a harder time getting work in the newly developed industrial sector. Although the plight of some resettlers has been quite difficult (one older man competed fiercely to serve as a porter for us for the royal sum of $6), and there are stories of suicide in some resettler communities, it is hard to separate the problems they face from the larger dislocations that are so prevalent in 21st century China.

Maybe the occasional feel-good story about, say, a child miraculously dug from the rubble days later, tired but unharmed and in good spirits, having survived on a cache of crackers and Coke. Actually, says John Mutter, an Earth Institute professor of sustainability studies, disasters can sometimes… read more

The Year of Drought and Flood

It seems that this year the world is experiencing a crisis of both too little water and too much. And while these crises often occur simultaneously in different regions, they also happen in the same places as short, fierce bursts of rain punctuate long dry spells.

Making Room for Rivers: A Different Approach to Flood Control

Over time, the U.S. Army Corps of Engineers, the federal engineering and construction agency, has spent over $123 billion on flood control infrastructure that hasn’t always adequately protected us. Now, with the devastation of the spring floods in the Midwest, some are calling for a new approach to flood control that makes room for our rivers.
