Agroecology in the tropics (journal)
Shifting agriculture in the tropics has been replaced by sedentary smallholder farming on degraded land. To address low yields and low income both, the soil fertility, the agroecosystem functions, and the source of income can be restored by diversification with nitrogen-fixing trees and the cultivation of indigenous tree species. Biodiversity studies indicate that mature cash crop systems, such as cacao and coffee with shade trees, provide wildlife habitat that supports natural predators. This review offers suggestions on how to examine these agroecological processes in more detail for the most effective rehabilitation of degraded land.
