Although shrimp farmers have expanded their operation and market through government support, their technical efficiency remains in question as they compete with other shrimp farmers in the area. This study investigates the technical efficiency of Vannamei white shrimp farmers and explores the factors affecting their inefficiency using the stochastic production frontier approach. Data were collected from 450 shrimp farmers in Chachoengsao, Thailand. Data were analysed using the stochastic frontier production function. Results showed that technical efficiency level was approximately 87%, implying a potential 13% growth in output if inefficiencies are addressed. Furthermore, farmers who receive training on shrimp farming are more efficient than farmers who do not. Farmers with higher educational attainment are more likely to be efficient implying the importance of providing information access and developing farmers’ technical knowledge on shrimp production. Thus, increased technical knowledge could enable farmers make better decisions and attain higher levels of technical efficiency.

Enforcement of rules to increase farmers' involvement in participatory irrigation management (PIM) has been ineffective given the non-exclusivity nature of surface irrigation. In this study, we investigated the interrelationship of the social capital's role in higher participation in PIM and the effects towards farmers' efficiency using the case of rice farmers in Northern Thailand. We found that higher intention to participate in PIM collective activities is largely driven by the water user's social capital endowments. Farmers' efficiency level is positively associated with PIM participation and the condition of the collective irrigation management. Our findings suggest the importance of complementing current government efforts with policy interventions focusing on strengthening water user groups' social capital, such as improving group cohesion and their capacity for networking in compensating for various impediments faced by farmers.

Youth have a strong role to play in environmental protection, and we should focus on developing their leadership skills through environmental education (EE). This research aimed to: (1) examine the competencies of environmentally educated young leaders; and (2) design an EE model for young leader development in Thailand. Questionnaires, focus group discussions, and in-depth interviews were conducted to collect data on what participants perceived to be key competencies for environmentally educated young leaders. Next, these data were used to create the EE model for young leader development. Finally, the model was applied to a training program for high school students, and its effectiveness was evaluated based on pre-and post-tests administered on the students. The evaluation results showed that the mean evaluation score rises from a moderate level before evaluation (x = 6.31, SD = 1.70) to a high level after evaluation (x = 8.85, SD = 1.01). The highest mean score is for public benefits (x = 9.06, SD = 1.02), followed by learning (x = 8.87, SD = 0.98), satisfaction on innovation (x = 8.78, SD = 1.02), and pro-behaviors (x = 8.70, SD = 1.02). Therefore, our proposed model can be used as a part of EE in schools for youth leader development.

Despite the increased popularity of organic rice in Thailand’s domestic market, little is known about how consumers’ behavioral and socio-demographic factors predict their purchase intention. Grounded on the theory of planned behavior (TPB), this research investigates consumers’ purchase intention for traceable organic rice. Responses were collected from 243 organic rice consumers in a farmers’ market in Chachoengsao Province, Thailand, following a convenience sampling approach. Data were analyzed using factor analysis, multiple linear regression, and one-way ANOVA to determine the factors predicting consumers’ purchase intention and identify any differences with respect to socio-demographic variables. Results reveal that subjective norms, perceived behavioral control, health consciousness, and knowledge of product traceability significantly predict consumers’ intention to purchase traceable organic rice. However, socio-demographic variables — age, income, and education, were found to have no impact on purchase intention. This study’s findings offer theoretical and managerial insights to community enterprises and policymakers to fully understand consumer behavior for organic rice and implement effective marketing strategies and policies.

Purpose: Organic rice forms the largest portion of the Thai organic food market. Because of its increasing popularity, marketers need to better understand consumer behaviour to address emerging concerns regarding product safety and quality and to tailor better marketing strategies relevant to the development of organic rice. As such, this study aims to examine consumers' purchase intention towards organic rice, using traceability information, and to investigate the direct and moderating roles of product traceability knowledge, using the theory of planned behaviour. Design/methodology/approach: Responses were collected from 243 organic rice consumers in a farmers' market in Chachoengsao Province, Thailand, following a convenience sampling approach. The gathered data were analysed using structural equation modelling to evaluate the strength of the relationship between the constructs. Findings: The findings reveal that subjective norms, health consciousness and product traceability knowledge have a significant positive influence on consumers’ intention to purchase organic rice. This study also establishes the moderating role of product traceability knowledge in perceived behavioural control and purchase intention, indicating that elaborated product information through traceability is essential for consumers who feel capable of buying the product. However, the direct effects of attitude and perceived behavioural control are insignificant, indicating the presence of external barriers to the purchase of organic rice, and that people may have a negative attitude towards the product. In addition, the cost perception result reveals that consumers consider price as an indicator of organic product quality, thereby increasing their desirability. Social implications: The findings of this study will help community enterprises in Thailand develop a more effective marketing strategy based on the identified motivators of organic rice purchase intention. Originality/value: This study develops a model that integrates important factors related to organic food consumption to generate a more comprehensive analysis of this mainstream research. To the best of the authors’ knowledge, this is also the first study to investigate the moderating role of product traceability knowledge to obtain a new and more focused understanding of how this factor influences purchase intention when applied explicitly to organic food. Finally, the findings provide theoretical contributions and implications for both the community enterprise and policymakers on developing strategies for organic rice marketing among community enterprises in Thailand.

Purpose: The purpose of this paper is to examine the effect of social capital with bonding and bridging distinction in promoting higher participation in collective action in participatory irrigation management. Design/methodology/approach: A sample of 304 farmers was surveyed using a structured questionnaire. A focus group discussion was also carried out with randomly selected water users, leaders and irrigation officers. A confirmatory factor analysis and structural equation modelling were used to test the hypothesised relationship of bonding and bridging social capital towards collective action. Findings: The findings show that social capital has a significant direct effect on collective action and an indirect effect on joint irrigation management's perceived performance through collective action (mediator). It implies the need to complement the participatory irrigation management programme with an understanding of the social aspects for a higher farmer's participation over the shared resource. Originality/value: The paper emphasises social capital's role in facilitating a real participatory engagement in shared resource management. Also, it is the first scholarly work linking social capital with bonding and bridging distinction towards collective action in a joint resource management context.

The idea of shared irrigation management is expected to result in a better production outcome for farmers. However, there is little evidence of whether collective action participation leads to a higher level of production efficiency. Using cross-sectional survey data from irrigated rice farms in Northern Thailand, we found that a higher level of production efficiency is associated with higher participation in collective action. At the same time, engagement in collaborative works such as irrigation maintenance, group meetings, conflict resolution, and policy adherence has a marginal effect on farmers’ efficiency. Our findings suggest that complementing existing efforts in addressing irrigation issues with efforts to mobilize collective actions among farmers leads to an improved on-farm outcome.

Bhutan aspires to be an entirely organic nation. Food self-sufficiency and increasing farm household income are critical priorities in the country. Realising these priorities necessitates assessing the country's current organic agriculture performance. The objectives of this study were to investigate the productivity and profitability of organic and conventional potato and farmers' constraints in producing organic potato in West-Central Bhutan. Multistage and purposive sampling techniques were used to select the study sample. A semi-structured questionnaire and face-to-face interviews were employed to gather primary data for the 2019 cropping cycle from 93 potato farmers: 43 organic farmers in the Gasa District and 50 conventional farmers in Wangdue Phodrang District. Descriptive statistics, cost and return analysis, and independent sample t-test were applied for data analysis. The results revealed that the conventional potato's productivity (tuber yield) and profitability were significantly higher (p < 0.001) than organic potatoes. The average productivities for organic and conventional potatoes were 7.48 and 19.22 t/ha, respectively. Organic potato farmers incurred a loss of -202,708.47 Ngultrum (Nu)/ha, while conventional potato farmers incurred a profit of 83,832.85 Nu/ha. The benefit-cost ratios of organic and conventional potato stood at 0.40 and 1.27, respectively. Lack of premium price, pest and disease problems, low crop productivity, and climate change were the constraints faced by organic potato farmers. The study found that the productivity and profitability of the conventional potatoes were higher than the organic potatoes in West-Central Bhutan in the current scenario. Further, the critical information will contribute to guiding Bhutan's vision for its organic agriculture development.

Agriculture is the prime source of economic activities, especially in Asia. In the okra export market channels, Japan was a major importer, yet suspended all importation of okra from Thailand, according to the promulgation of the Positive List System. This study aimed to: 1) estimate one particular type of productive efficiency, viz. technical efficiency, in okra production in Thailand's Suphan Buri and Nakhon Pathom Provinces, by using a Cobb-Douglas production function for single okra output and multiple inputs. The analysis applied the Stochastic Production Frontier; 2) investigate the determinants of production efficiency by using Tobit regression. Based on data collected from 222 okra farming households in two provinces, who contracted with private companies to produce okra for export. The results revealed that the average technical efficiency of okra production among the samples in Suphan Buri and Nakhon Pathom Provinces was 81.45%. Furthermore, the results showed that okra growers' gender, age, formal years of schooling, number of family members engaged in okra production, and hired labour had positive relationships with efficiency scores. While years of experience in okra production had a negative effect.

Growing urbanisation, dwindling land for rice cultivation, and declining numbers of rice farmers have been major concerns. Yet, many local people living in peri-urban areas still produce rice for their livelihood. This study aimed to estimate the sustainable efficiency (SE) of the rice farmers in the peri-urban areas and investigate the determinants of SE by employing a multiple linear regression methods. Based on data collected from 230 rice farmers in the Ladkrabang district, the peri-urban area located to the East of Bangkok, Thailand, this study revealed that, on average, the SE of sample rice farmers was 0.84. The large-sized farmer had a higher average SE than small-sized and medium-sized ones. The results of regression analysis indicated having heirs working in farm was the most effective variable on the SE of rice farming, followed by participation in agricultural training programs, formal years of schooling, the number of family labour, and subsidies.
