干旱区生态环境知识资源中心

As the land degradation is a complex process, influenced also by climatic and human-induced factors, its understanding and mapping requires a methodology based on Earth Observation integrated with ancillary data such as socioeconomic and, optionally, meteorological data. For this reason, the service, which has been defined, implemented, and validated in close cooperation with End Users, is based both on scaleable indexes - derived from Earth Observation data - and on indicators relevant to the influence of human and animal pressure on natural resources. The ultimate goal is the generation of vulnerability maps to provide to decision makers for prevention purposes.
