There is international concern over the problem of rapidly diminishing forest resources. Within some Asian countries, forest loss has been catastrophic. The Philippines has lost 90 percent of its jungles in the last 50 years. Indonesia had an annual lost up to 550,000 ha of forest. Over half of Thailand used to be forest two decades ago, at present only 28 percent is under forest cover. Shifting cultivation, illegal logging and the increasing need for wood were the causes of this loss. The consequence of deforestation and degradation of forest resources has resulted in innumerable deteriorations of biological system; the depletion of soil fertility caused by erosion, uncontrolled flood and low agricultural productivity. All these have an unavoidable impact on the economic, social and environmental conditions of the country. To tackle these problems and to cope with the human demand in upgrading the standard of living for rural poor, attempts have been made to find ways to maintain the forest area and increase the forest plantation. Multipurpose Tree species (MPTS) particularly the nitrogen-fixing trees are becoming more interested by foresters and researchers for their important roles in the establishment of forest community, agro-forestry and reforestation program as well as for commercial and industrial purposes. Research and development of MPTS is a feasible way to approach the problem of wood shortage and deforestation.
