摘要
The non-profit association ITHACA cooperates with the World Food Programme in order to define a global drought Early Warning System, mostly based on satellite data, with the scope of mapping critical areas that may be potentially subject to food crises. In 2010 the African regions of Sahel, especially Niger and Chad, faced a relevant food crisis due to strong deficits in agricultural and pastoral production, and the World Food Programme requested technical support to outline the areas most affected by drought. Testing the tools under development, ITHACA analyzed environmental conditions potentially related to the 2010 food crisis. The paper describes the studies performed and their contribution to the improvement of the ITHACA drought Early Warning System.
