Taught in the Foundation stream
The discipline covers land degradation, desertification, deforestation and land-use change, soil health and erosion, and the role of land in carbon, water and food systems.
Courses in development extend the scope to further subjects: Land degradation, soils and land tenure; Amazon and tropical forest risk.
Search any place or open the world; the layers and generators follow land, forests and soils on the planet map, the globe and in 3D.

Rainfall erosivity, soil erodibility, slope and cover multiply into a soil loss rate; set against the slow rate at which soil forms, that rate gives the years until a topsoil is gone and the carbon it takes with it, and the comparison with a tolerable loss is the decision.
