Agricultural Drought Monitoring Using Space-Derived Vegetation and Biophysical Products: A Global Perspective
Since long time, agricultural monitoring systems use space remote sensing (RS) instruments to provide timely and synoptic information about drought. A variety of approaches are currently being used and most of them based on the analysis of RS data in the optical domain. They permit the mapping of vegetation vigour, as well as hydrological variables such as rainfall and evapotranspiration. Sensors operating in the microwave domain provide additional and valuable information regarding soil moisture.
This chapter, after providing background information about drought monitoring indices and systems in general, will focus on the current operationnal use, by the Food security and Agricultural Monitoring Community of practice of satellite-derived biophysical indicators of vegetation status from RS in the optical domain.
