EFG T7.1 Croplands – current maps

T7. Intensive land-use biome

This page provides information about the valid indicative distribution map for the ecosystem functional group T7.1 Annual croplands. For older or alternative maps, see here.

Methods

Here is the methods summary for Map code and version: T7.1.web.alt v2.0.

Major occurrences of croplands were taken from the map of Habitat type 14.1 by Jung et al. (2020) based on the IUCN Habitats Classification Scheme v3.1 (IUCN 2012). We compared this to cropping areas in consensus land-cover maps (Tuanmu et al., 2014) and found that maps of Jung et al. (2020) more closely matched the concept of T7.1.

Datasets
