Note: Land-use codes for Tables 9.5-9.11:
1. Annual cropping; 2. Agroforestry; 4. Shrub-dominated fallow; 6. Orchard - plantation; 7. Orchard - trees;
8. Native forest (sacred grove); 9. House garden; 12. The special case of
proka
(agroforestry)*.
* It has been explained why
proka
is not a land-use form or stage but a method of land preparation employed in traditional peasant
agroforests.
