This quantitative research aimed at studying the existing situation of oil palm plantation, and analyzing determinants of oil palm plantation area in Thailand. Quantitative data used were annual time-series data during 1989 to 2010. The derived data were analyzed using appropriate descriptive statistics, and enter and backward multiple regression analyses. The results showed that Thai oil palm plantation and harvested areas have increased for more than 3 decades. They have been significantly increasing in southern Thailand. Statistically significant determinants of Thai oil palm plantation areas at the .05 level were the domestic demand for crude palm oil, the farm price of fresh bunches of oil palm fruit, the price of diesel oil and the farm price of unsmoked rubber sheet 3. These determinants could be used to create conservation and sustainable management guidelines for the expansion policy on future oil palm plantation area. |

Primary data were collected using structured questionnaires from a total sample of 388 consumers, using the accidental sampling technique. Descriptive statistics and logistic regression were applied for data analysis. The results revealed that the majority of health product consumers were female with an average age of 31.27 years and had a bachelor degree. The marketing mix in terms of product, price, place, and promotion was a very important influence on the decision to purchase health products made from cold-pressed palm oil. The statistically significant variables determining the purchasing decision on health products made from cold-pressed palm oil were sex, age, marital status, government official, level of importance given to price, place, and promotion, with respective purchasing decision probabilities of 0.12, 0.006, 0.12, 0.61, 0.11, 0.12 and -0.19, respectively. The results are useful for entrepreneurs to formulate appropriate marketing strategies for health products made from cold-pressed palm oil. |

A total sample of 395 rubber smallholding households that used hired labor was used for data collection through structured interviews. Also, 60 households of the total sample were used for in-depth interviews. Descriptive statistics were used for data analysis. The results classified the dynamics of hired labor into 5 periods; (1) before 1960: traditional rubber production, (2) 1961-1980: green revolution, (3) 1981-1992: alternative agriculture, (4) 1993-2002: initial industrial rubber production, and (5) 2003 to present: industrial rubber production. There was an increase in hired labor in rubber production with more complications in the hired labor process. There were 5 types of hired labor according to the sources of labor: relatives as hired labor, villagers as hired labor, different district or province hired labor in the south, different farmer households had a tendency to hire more tapping labor. This would affect the benefits of sharing between owners and hired laborers that could be divided into 3 patterns of: contract agreement, daily wage paid, and wage paid by activity. In the contract agreement, benefit ratios between owners and hired laborers were 60:40, 55:45, 50:50, and 70:30. Choosing a benefit ratio would depend on: (1) the skill and experience of the hired labor in working in rubber plantations, (2) the number of household laborers, (3) local wage rates and contract agreement characteristics, (4) farm size holding and labor capacity, (5) the impact of socio-economics, environment, policy, and politics, and (6) the frequency of tapping to increase family income when there was a high rubber price. The guidelines for the development of hired labor in the rubber production system were: (1) strengthening the socio-economic status of hired labor, (2) promoting relationships between owners and hired labor, (3) improving the bio-physical characteristics of the rubber plantation area, (4) promoting fair conditions and a contract agreement of benefits, (5) improving labor quality, and (6) increasing the skill of tapping and working hired labor through knowledge transfer and training processes. |

Quantitative and qualitative methods were used in this research. A total sample of 394 rubber households that used household labor without hire labor in all activities of the rubber production system, was used for quantitative method. Also, 60 households of the total sample, officers of the Department of Agricultural Extension and officers of the Office of the Rubber Replanting Aid Fund in Songkhla province were used as key informants for qualitative method. Both structured and unstructured interviews were used for data collection. Appropriate descriptive statistics were used for data analysis. The research found that there were 4 types of household labor in the smallholding rubber production system: 1) husband and wife, 2) children, 3) relatives, and 4) elderly labor with more complicated use of household labor according to the development of rubber. Each type of household labor worked on different activities which suited their abilities and amount of work carried out by household labor in rubber production knowledge and capability of working in the smallholding rubber production system when compared with other types of household labor. Guidelines for development of household labor in the smallholding rubber production system were development and improvement of skills, knowledge, and capability of household labor in rubber production activities. In addition, the relevant agencies should have plans and policies for labor in agricultural sector. |

It was found that the sampled consumers were highly satisfied with the biodiesel products and prices. They were moderately satisfied with selling place and product promotion. The statistically significant variables determining; 1) consumers? satisfaction on the biodiesel product were their assigned importance to biodiesel product availability, their price and places of sale, and consumers? expenditure on biodiesel; 2) consumers? satisfaction on biodiesel price were their assigned importance to prices and places of sale, and consumers? expenditure on biodiesel; 3) consumers? satisfaction on biodiesel place were their assigned importance to places of sale and product promotion; and 4) consumers? satisfaction on biodiesel promotion were their assigned importance to prices and product promotion, and consumers? expenditure. |
