CHENNIMALAI, India – There is river and beach sand aplenty in Tamil Nadu. At 130,000 square kilometers (50,200 square miles), the state is about the same size as Nicaragua and has 95 rivers with sandy bottoms and a long Bay of Bengal shoreline. Or did. For almost all of its thousand-year history, the state of Tamil Nadu took all that sand for granted. No longer.

Water scarcity has contributed to an “arc of instability” characterized by conflict and displacement that stretches from West Africa to the Middle East, said a panel of experts at the Wilson Center on March 1.

VILAMBUR, India – The mammoth coal-fired Cheyyur electrical station was first imagined by bankers at India’s Power Finance Corporation and senior engineers across town at the Central Electric Authority. That was in 2005, when the country was rich in fossil fuel resources and desperate for electric power. Though India mined more coal than almost any other country, endemic blackouts and brownouts enfeebled its economic prospects.

In the dead of night on February 15, gunshots blasted the guards into action in India’s Kaziranga National Park. Rangers stationed in a nearby camp quickly spread out, searching for the shooters under the light of a nearly full moon – to no avail.
