Severe droughts experienced recently in countries such as China, Brazil and the United States can no longer be seen as purely natural hazards, acording to a new aper. Changes to the way people use the water and the landscape contribute to extreme water shortage

Abstract

Drought management is inefficient because feedbacks between drought and people are not fully understood. In this human-influenced era, we need to rethink the concept of drought to include the human role in mitigating and enhancing drought.
