    Warming Climate Could Abruptly Increase Rain in Africa’s Sahel

    Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability. In the study, just published in the journal Earth System Dynamics, the authors detected a self-amplifying…

    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,”…

    Reduced U.S. Air Pollution Will Boost Rainfall in Africa’s Sahel, Says Study

    If U.S. sulfur dioxide emissions are cut to zero by 2100, as some researchers have projected they will be, rainfall over Africa’s Sahel region could increase up to 10 percent from 2000 levels, computer simulations suggest.

    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.

    Forest-Friendly Development Can Bolster Peace in Colombia, Paper Says

    As Colombia rebuilds following last year’s historic peace deal with Marxist FARC rebels, it has an opening to advance sustainable land development, a new study contends.
