Rangeland management in former tropical rainforest areas may affect ecosystem services. We hypothesized that management practices like burning and overgrazing reduce supporting (soil quality) and consequently also provisioning (forage productivity and quality) and regulating (nutrient cycling) ecosystem services.

PIM support to work from ILRI and partners contributed to adoption of a woreda (district) participatory land use planning approach in Ethiopia and to expansion of the joint village land use planning approach in Tanzania, resulting in more secure tenure rights for pastoralists in rangeland areas.

Human populations and their use of land have reshaped landscapes for thousands of years, creating the anthropogenic biomes (anthromes) that now cover most of the terrestrial biosphere. Here we introduce the first global reconstruction and mapping of anthromes and their changes across the 12,000-year interval from 10,000 BCE to 2015 CE; the Anthromes 12K dataset.

ICARDA continued to play a critical role in the development, improvement, and dissemination of climate-resilient crop varieties last year. The varieties strengthened food and nutritional security and provided a critical defense against extreme temperatures, water scarcity, and the emergence of new pests and diseases.

Tetra Tech’s land tenure and property rights experts examine how weak land and resource governance can fuel drivers of violent extremism. With a focus on the African Sahel, this new issue brief finds this dynamic is especially prevalent when land and resource governance challenges are coupled with environmental disruptions, resource scarcity, or migration.

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).
