| Research Abstract |
1.Total area of tropical acidic swamps distributes more than 2,000 ha in Malay Peninsula, Mekong Delta in Vietnam, Kalimantan Island. Barren lands by such as salt accumulation including strong alkali at Northeast China and desertification are expanding. Such barren lands were mainly caused by human activities to increase agricultural products, and are going to be expanding by land use changes with plan less development. So far we have investigated empirically and ecologically the possibility of the establishment of management system for sustainable biomass production in Southeast Asia region and also barren land area in China, in the view point of the relationship between land use change and human activities including regional economy, technologies and culture.
2.Southeast Asia region and China is the treasure house of biomass production of the world. Land area and population of such area are 15.4 and 55.0% of the world, respectively, the production of major crops and vegetables are 50

and 83% of the world. Plantation products such as palm oil, coconut oil and natural rubber, which are essential as industrial resources, are produced more than 84% of the world demand in Southeast Asia. However, it has made clear that the sustainability of such biomass production is getting to be difficult because of destruction of forestry for development of agricultural field to correspond to overpopulation and industrial development. In addition, productivity of agricultural land is decreasing by rapid destruction such as acid soil, salt accumulation and desertification by use of much amount of chemical fertilizers and chemicals such as pesticides to increase agricultural production.
3.There are many efforts to recover sustainability of biomass production such as development of tolerant varieties, effective utilization of biomass and restoration technologies under such seriously critical moment.
4.It would be very important for activation of regional economics harmonized with regional environment and ecosystem to establish the biomass industrial complex with zero-emission system using by-products (wastes) which are produced together with production of biomass. Less
