Global Agricultural Stress Index (ASI)

The Agricultural Stress Index (ASI) produced by FAO depicts the frequency of severe drought affecting crop areas by means of remote-sensed Vegetation Health Index (VHI). FAO provides decadal, monthly and annual drought frequency over the period 1984-2024 split as the main crop season (S1) and secondary crop season (S2). For each season there are two indicators, according to two exposure intensity thresholds:30 percent (1/3) of cropland area being affected by the drought event50 percent (1/2) of cropland area being affected by the drought event
