Soil erosion is a major problem limiting availability of nitrogen and other nutrients for crops on sloping lands in Southeast Asia. The Integration of timber trees with annual crops in contour hedgerow systems reduces erosion, increases farmers’ income and improves environmental services such as water quality and carbon sequestration. This integration is considered a viable option for smallholder farmers in the humid tropics of SE Asia.
