This indicator measures the total dryland area (in sq. km) that can be defined as subhumid, in a given country.

Aridity zones were derived from an Aridity Index (AI) which is calculated as the ratio of precipitation to potential evapotranspiration (P/PET). Subhumid areas fall into the 0.50 - 0.65 P/PET interval.

 

The values of this indicator have been aggregated at the country level by ILRI, in collaboration with the ILC's Rangelands initiative, based on:
