Upland farmers in Vietnam are associated with the lowest income and face serious issues of natural resources degradation and environmental pollution because of poor agricultural practices. To persuade the upland farmers to adopt sustainable practices, it is vital first to assess their perception of sustainable agriculture. This study aimed to measure banana farmers' perception towards sustainable agriculture and its determinants in the Vietnam uplands based on a case study in Quang Tri province. Stratified sample technique was used to randomly select 300 respondents from 2 upland districts of Quang Tri. The primary data were gathered by using a structured questionnaire with Cronbach's alpha coefficient of 0.84. The results showed that the majority (84.7%) of the farmers had low to mode rate perceptions of sustainable agriculture. Farmers had positive perceptions towards sustainable agriculture in issues related to protection of agricultural resources, negative effects of agrochemicals on human health and the environment, input application, crop rotation, product consumption and roles of farmer groups; whereas, they had moderate perceptions about issues related to production profits, plant residue use and modern technology application. In addition, the study revealed that agricultural programs on TV, education, ethnic group, economic status and credit use were the factors that affected farmers' sustainable agriculture perceptions.

This empirical study investigates the causality between agriculture and economic growth in Thailand over the period of 1961 to 2009. A Granger causality approach and the Wald (χ 2 ) coefficient statistic are utilized to reveal a long-run causal relationship and impact transmission between the variables. Based on the time series analyses, a long-run relationship and size impact are detected running from agriculture to economic growth, and vice versa. These findings including with the generalized variance decomposition show that agriculture is existed in a long-term stable in economic growth while economic development encourages the growth of agriculture as a whole. As a conclusion, policy-makers should regard agriculture as an important supporter of Thai economy.

Thailand is the largest durian producer and exporter in the world market. In addition, durian is the most important fruit crop in Thailand because it can generate a higher income from exports with a value of approximately 45,349-million-baht, equivalent to an export quantity of 653,564 tons in 2019. The objective is to analyze the factors affecting the durian production of farmers in the eastern region of Thailand, namely Chanthaburi, Rayong, and Trad Provinces. The sample of 395 durian farmers underwent observation using simple random sampling via the questionnaire approach. The statistics consisted of mean, percentage, and multiple regression. The findings revealed that the positive factors affecting the durian production of farmers in the eastern region of Thailand are the experience of the farmers in growing durian, the size of the workforce, the planted area of durian, the number of durian trees, and the number of durian trees per planted area, while the negative factors affecting the durian production of farmers in the eastern region of Thailand are the age of the farmers and the cultivation of organic durian. The results will be beneficial to farmers, government, and related stakeholders, who can further apply these findings to enhance the efficiency of durian production to be the quality durian for domestic and foreign consumers

The purpose of this study is to forecast the import demand of table grapes of Thailand using monthly time series from January 2007 to April 2020. The ADF unit root test is used for stationarity checking, and seasonal autoregressive integrated moving average (SARIMA) is applied to forecast the import demand of table grapes. The results revealed that the integration of time series was in the first difference for non-seasonal and seasonal order. The best-fitted forecasting model was SARIMA(1,1,3)(2,1,0)12. The forecasted period for the next eight months showed the import demand of table grapes of Thailand that is slightly decreased by an average of 11.398 percent, with overall expected to decrease by an average of 15.218 percent in 2020.
