It is notable that there is already approximately 7,000 Rai (1,100ha) of oil palm planted area in Loei province, where Na Duang village is located. In Na Duang village, majority of farmers who had started oil palm plantation joined the Community at its establishment. Oil palm plantation is expected as a new industry in the area. Table 2.

Poultry is usually bred in small number and free-ranged in farmers garden, therefore, does not appear in the statistics Table 4.

Feeders traditionally utilize rice bran as fish meal. The efficiency of feeding is not good as feeders spread and float in the water when thrown into the fishing pond because of rice bran’s traits (dry and small particles) Table 5.

Tilapia inhabit in a variety of fresh water all over the world, and is common in Thailand for human consumption 3 2) Socio-economic situation of the subject area <Thailand> ・ Increasing need for biomass utilization: In Thailand, import of crude oil has three folded in the last 20 years due to the growing energy demand. Therefore, stable procurement of energy source has become the country’s one of the most pressing issues. In addition to this, in 2007, Thailand faced with a significant economic downturn due to the sudden rise of oil price worldwide. Simultaneously, price of commodities, especially, of which large proportion of production cost was occupied with oil, increased rapidly and struck people's life in Thailand. Since then, the country is undergoing drastic review of its economic structure highly dependent on fossil fuels. The effort to seek for use of biofuel and substitute for products dependent on fossil fuel is continued up until now. ・ Increasing demand for organic fertilizer: In the agricultural sector too, many farmers are seeking to use organic fertilizer rather than chemical ones due to the emerging awareness on health and organic agriculture, as well as the negative impact on farmers from increased price of chemical fertilizer since the 2007. According to the National Statistics, average income in the northeastern region in Thailand, where the majority is engaged in agriculture and/or related business is the lowest in comparison with other zones in Thailand. Therefore in terms rectifying the economical disparity between urban and rural area, agrarian development policy based on biomass utilization is encouraged. The policy is bearing fruits slowly but steadily. <Na Duang Village> ・ Agriculture as main industry: Agriculture accommodates the majority of earning opportunity in Na Duang village and the main crops are maize, rubber, rice, soybean and cassava. Farmers select advantageous crops according to the market situation. Currently, more than 50% of fertilizer used in the area is organic. However, it is said that use of chemical fertilizer, pesticides, and herbicides is increasing. In general the size of farmlands of individual farmers in Thailand is relatively small. These farmlands are further subdivided into small plots when inherited to the next generation. ・ Facilities for supporting agriculture: In order to support agricultural activities, which is the main industry of the village, 4 there are 3 compost facilities in the village including the facilities subsidized by the local municipality, that utilizes biomass such as rice straw, rice husk, rice bran and corncob. However, due to the difficulty of procure raw material, those facilities are not fully operated. In another case, autonomous small farmers group is conducting survey regarding compost, and producing compost by themselves. Compost is produced by utilizing raw material available within the group, using space in/around residential area and using almost only manpower and simple equipments. ・ Depopulation and aging society: Because of limited employment opportunities and stagnant income growth rate due to the country’s social structure which is dependent on agriculture and/or agriculture related industry, there is a tendency that many young people migrate from villages to cities. As a result of this, the society in the rural area is depopulating and aging.
