Agronomist with specialization in applications of remote sensing for agriculture. After 10 years on control of CAP subsidies with remote sensing and GPS, I moved to the group dealing with food insecure countries; we monitor agriculture (with a foucus towards drought) in 80 food insecure countries on a monthly basis (see JRC ASAP); we also work on yield forecasting at regional (infra country) level using meteo and remote sensing yield indicators. Our main challenges there are to access crop statistics (over at least 15 years) and find relations between these statistics (which may be biased) and yield indicators (the ones we have may not be the best ones).
