Abstract
Results show that planted fallows with economically valuable trees such as Inga and Colubrina have the potential to raise farmers' income and alleviate degradation of natural resources in the humid tropics of Peru. However, they require more testing under a range of biophysical and socio-economic conditions. Short-duration planted tree fallows may be a solution to overcome problems of traditional land use. Increased population pressure in the Peruvian Amazon has reduced fallow periods in recent years, leading to rapid soil degradation, low crop yields and greater deforestation. Only pure Centrosema significantly increased maize yields.
