This database will be used mainly for poverty and food insecurity mapping, particularly for analysing where the people live
at global scales in relation to:
- Agroecological zones
- Marginal or productive lands
- Major foodcrop production systems, in particular those important to food security for the rural poor.
The thermal climates were obtained through classifying monthly temperatures corrected to sea level. The thermal climates
distinguished in global AEZ are the following: tropics, subtropics (2 subtypes), temperate (3subtypes), boreal (3 subtypes)
A layer (.lyr) and legend (.avl) file are provided in the data download.
