Resumen
Descripción
The idea of ASIS-global is to simulate the analysis that a remote-sensing expert would undertake, and to express the results in simplified form as maps for final users. Every 10 days, ASIS generates a map for the GIEWS team showing “hotspots” around the world where crops are affected by water shortage during the growing period. To avoid generating false alarms, the “hotspots” identified have to be confirmed with data from public institutions and, if possible, checks are conducted on the ground, or socioeconomic variables such as the variation in agricultural product prices are analysed. It is also possible to verify the “hotspots” using agro-meteorological models with data obtained from the national meteorological network, which ultimately show indicator convergence.
