Global ruminant production systems found in rangelands

Maps
December, 2018

This map shows global ruminant production system that exists within rangelands. Selected classes are: LGY (Livestock-only systems in Hyper Arid areas), LGA (Livestock-only systems in arid areas), LGH (Livestock-only systems in humid areas) and LGT (Livestock-only systems in temperate areas or Tropical Highlands). The mapping of global ruminant production systems was undertaken by FAO and ILRI. The mapping of the rangelands is taken from rangeland types and boundaries previously mapped by University of Idaho and the Society for Rangeland Management (SRM).

Global rangelands with country boundaries

Maps
December, 2018

This map shows rangelands globally per country based on categorization of all 867 ecoregions in the TEOW(Terrestrial Ecosystems of the World) using the definitions of rangeland ecotypes and non-rangeland ecotypes, providing approximate areas of rangelands per country. This map classifies rangelands into four rangeland ecotypes (grasslands, shrublands, savanna/woodland, and tundra) and combines non-rangeland ecotypes into one 'other' layer. Rangeland types and boundaries were previously mapped by University of Idaho and the Society for Rangeland Management (SRM).

Drylands located in rangelands, with country boundaries

Maps
December, 2018

This map shows Drylands found in Rangelands (using global aridity classes) mapped against country boundaries providing approximate areas of Drylands found in rangelands per country. Aridity zones were derived from an Aridity Index (AI) which is calculated as the ratio of precipitation to potential evapotranspiration. Zones included in this dataset are: hyperarid, arid, semiarid, and dry subhumid. These are in accordance with the United Nations Convention to Combat Desertification (UNCCD) definition of Drylands and previously mapped by UNEP-WCMC 2007.

Country boundaries were taken from ESRI 2016.

Anthropogenic biomes found in rangelands globally

Maps
December, 2018

This map shows global historic" Anthropogenic Biomes" of the world (as mapped by Ellis et al 2000) that exists within rangelands, selected classes are: Pastoral Villages, Residential Rangelands, Populated Rangelands and Remote Rangelands. The mapping of the rangelands is taken from rangeland types and boundaries previously mapped by University of Idaho and the Society for Rangeland Management (SRM). Country boundaries were taken from ESRI 2016.
