Global drylands and climatic resource poverty
The Climatic Resource Index (CRI) is an indicator of the climatic potential for biomass production. It is based on a combination of the annual growing-degree-days above 0°C and the annual aridity index, rescaled to values between 0 and 100. The index takes into consideration whether an area is irrigated or not, and to what extent. The Climatic Resource Poverty Index, shown in this map, is calculated as 100-CRI.
