LU2- “wet cultivation” (lower left) includes LU3 categories: LU3-“rice paddy/taro pond fields” represented by rice paddies, LU3-“raised fields/chinampas” shown by chinampa agriculture and LU3-“wetland cultivation” shown by cereal and pulse cultivation on river floodplains. LU2-“agroforestry/arboriculture” (lower right) includes LU3 categories: LU3-“arboriculture (tree crops)” shown with an apple orchard, LU3-“agroforestry” without soil enrichment shown through a woody perennial management system with undifferentiated soils from unexploited areas, and LU3-”agroforestry with soil enrichment of woody perennial management” with a Amazonian dark earth soil.
