Drought Risk
WorldPhysical EnvironmentAreas of the world at risk for future drought. Risk is determined by a combination of environmental factors (e.g., historic drought occurrence), human factors that affect the likelihood of drought exposure (e.g., crop production, grazing, etc.) and social, economic, and infrastructure factors that affect how well a population can cope with drought (e.g., water impoundment and delivery).
A world map shows drought risk levels, depicted in various colors from dark red as risk level 9 to very light yellow as risk level 1. Some of the highlighted regions are Level 9: some areas of India. Level 1: some areas of central Africa and Vietnam.
