Cost and Benefits of Highland Agroforestry System in Northern Thailand

Abstract

Costs benefits and cost of seven highland agroforestry systems on mountainous areas of Chiang Mai and Mae Hong Son provinces were analyzed during October 1998 to June 1999. The results showed that the various agroforest plantations of Coffea arabica and rice plant in Melia azedarach plantation provided high net income, while tea plantation in hill evergreen forest, cabbage inter-planted in Pinus kesiya plantation and Leucaena leucocephala plantation for cutting leaves had low net benefit. However, cost and benefits ratio of all systems were more than 1.
