Increase of population and its associated pressures on agricultural land have threatened tropical forests in the production of food, fuel, and timber. After deforestation, it is often difficult to sustain annual crop production since nutrients are rapidly leached from the soil due to high rainfall in the tropics. There are several sites and systems of agroforestry where agriculture is combined with forestry to provide food and wood without causing a degradation of the ecosystems in the Philippines. We investigated sites where agroforestry is applied using sloping agriculture land technology in Ilocos Norte and multistoried cropping systems in Cavite in 1991. Although the topography of these sites was different, the common feature was the emphasis placed on soil and water conservation as well as on soil fertility maintenance using trees and crops at the same time and sequentially, since these were the major factors affecting further development and sustainability of the upland areas.
