Concise description:

In the broad context of drought Early Warning, ITHACA's efforts are oriented towards the development of an automated system (Drought Monitoring), able to monitor relevant environmental variables thus enabling the detection and characterization of vegetation stress conditions. Different parameters are integrated into a simplified drought risk model which considers environmental data related to vegetation production and rainfall. In particular, the near real-time monitoring of satellite derived vegetation indexes allows the early detection of water stress conditions of vegetation, and the monitoring of derived phenological parameters. The latter, coupled with the evaluation of precipitation conditions, leads to a near real-time assessment of the vegetation productivity expected at the end of the considered growing season. The timely detection of critical conditions in vegetation health and productivity allows to spot agricultural areas with increased potential of crop failure or food crisis risk.

Indices included:

SPI-3, SSID, DWI
