    In Jharkhand, Using an Old Technique for Sustainable Water

    The Indian state of Jharkhand has plentiful rainfall, but most of that water runs off before it can be put to use by farmers, who struggle to make a living. To help improve irrigation and crop productivity, the Centers for International Projects Trust and Ranchi’s Birsa Agricultural University turned to a simple traditional technology, “dobhas,”…

    Project Uses Satellites for Rapid Assessment of Flood Response Costs

    Overall global losses from natural disasters such as floods, landslides or earthquakes amount to about $300 billion annually. A rapid and early response is key to immediately address the loss of human life, property, infrastructure and business activity.

    Study: Overuse of Water Threatens Global Food Supply

    In recent years, scientists have revealed that we are depleting our global groundwater reserves at an alarming rate. Now researchers have shown that a significant share of this unsustainable water use fuels the global food trade, which means water exhaustion in supplier nations could ripple outward, causing food crises half way across globe.

    The Glaciers Are Going

    Glaciers around the world have retreated at unprecedented rates and some have disappeared altogether. The melting of glaciers will affect drinking water supplies, water needed to grow food and supply energy, as well as global sea levels.

    An Ancient Tool Holds Promise for Modern Water Problems

    The potential effectiveness of harvesting rainwater to bolster water supply and reduce potentially polluting runoff varies greatly from place to place, even within a particular city or neighborhood. Now researchers at the Columbia Water Center have developed a tool to assess the potential of rainwater harvesting throughout the United States.
