    To the tip of the Andes

    In the semi-arid Andes, glaciers store water and control the runoff of mountain rivers. They feed water to big cities such as Lima and Arequipa and irrigate the surrounding lowlands. But as the planet warms, mountain glaciers in the tropics are receding steadily. Despite their paramount importance, we don’t know the scale and the rate…

    New Water-Smart Communities Prepare For a Water Scarce Future

    A recent study by the Stockholm Environment Institute warns that the American Southwest is exhausting its water resources, and if water use isn’t reduced, “The cumulative water shortfall for the Southwest for the next century, without adaptation, will be 1,815 million acre feet” due to population and economic growth. Climate change will, of course, make…

    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…
