This paper explores the relationship between land cover change and albedo, recognized as a regulating ecosystems service. Trends and relationships between land cover change and surface albedo were quantified to characterise catchment water and carbon fluxes, through respectively evapotranspiration (ET) and net primary production (NPP).

Feed and grazing management affect both the quantity and quality of animal manure and consequently nutrient cycling in the mixed crop-livestock systems in West Africa Sahel. Dietary measures can significantly influence the composition of manure and hence it’s agricultural value.

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.

This map shows terristrial protected areas found within rangelands. The information on protected areas is taken from IUCN and UNEP-WCMC World Database on Protected Areas. 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.

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.
