Audio: A Hydrogeologist Talks About his New Technology to Protect Communities from Floods
Floods and drought are often two sides of the same coin. In certain places, they damage soil, water systems and ecosystems in repeating cycles that exacerbate each other’s impact.
South Asia is one example of such a place. During the dry season, any rain passes straight through what are often degraded soils, leaving crops to wither in the sun. Instead, farmers, firms and factories rely on wells that tap underground reservoirs. But this resource is quickly depleted because most monsoon rainfall runs uncontrollably off the land, without replenishing the underlying water.
