Land cover types

Agriculture

* Agricultural land: Cropped land, fallow land and grassland (excluding extensive grassland) 

• Extensive grassland: Land covered by grass with potential productivity of less than 25% of world maximum for grassland
• Biofuel Land: cropped for biofuels

Managed forest land and regrowing vegetation

* Carbon plantation: Lands planted with wood species used for biofuel production or C sequestration  

• Regrowing vegetation (abandoning): Abandoned agricultural land that reverts back to its natural vegetation
• Regrowing vegetation (timber): Vegetation harvested for timber or fuelwood production that reverts back to its natural vegetation type
• Wood plantations: Planted forests where management is optimized for efficient wood production with shorter rotation cycles.
