A Knowledge-based Geo-Spatial Decision Support System for Drought Assessment
نویسندگان
چکیده
Drought affects virtually all regions of the world and results in significant economic, social and environmental impacts. The Federal Emergency Management Agency estimates annual drought-related losses in the United States at $6-8 billion, which is more than any other natural hazard. Congress enacted the Agricultural Risk Protection Act of 2000 to encourage the United States Department of Agriculture (USDA) Risk Management Agency (RMA) and farmers to be more proactive in managing drought risk. Current drought crisis management remains reactive, where action is dormant until the onset of threat. Despite billions of dollars in lost revenue, no comprehensive system exists for drought (Wilhite, 2000).
