| Note |
Combined Drought Indicator (CDI) Input: Soil Moisture Anomaly (SMA), Anomaly of Vegetation Condition (FAPAR Anomaly), Standardized Precipitation Index (SPI-1), Standardized Precipitation Index (SPI-3) http://edo.jrc.ec.europa.eu/documents/factsheets/factsheet_combinedDroughtIndicator.pdf To identify not only areas affected by agricultural drought but also areas with the potential to be affected. The method consists in a classification scheme based in three drought impact levels, corresponding to the different stages of the idealized agricultural drought cause–effect relationship. These levels are named as “Watch”, “Warning” and “Alert”. Two additional levels, “Partial recovery” and “Recovery”, identify the stages of the vegetation recovery process. A precipitation reduction respecting to the average is the primary driver of drought. When this precipitation reduction produces a decrease on soil moisture enough to not satisfy the water demand of the plants and therefore affecting its physiological processes, we are talking about agricultural drought. |
