Planetary Boundary Nr 7: Land system change

Land is converted to human use all over the planet. Forests, wetlands and other vegetation types are converted primarily to agricultural land. This land-use change is one driving force behind reduced biodiversity and has impacts on water flows as well as carbon and other cycles. Land cover change occurs on local and regional scales but when aggregated appears to impact the Earth System on a global scale. A major challenge with setting a land use-related boundary is to reflect not only the needed quantity of unconverted and converted land but also its function, quality and spatial distribution.
