摘要：This empirical research investigates the factors influencing the adoption of three irrigation technologies using a probit statistical model: water wheel (WW), water pump (WP), and weir (WR) irrigation technologies as well as their economic returns per unit of rice cultivated area. The influencing factors were categorized into demographic, socioeconomic, topographical, institutional, and attitudinal factor groups by 207 rice-growers in the Chaiyaphum province in northeastern Thailand. The results revealed that the land holding size, farm income, and water use association (WUA) membership factors were highly positively associated with the WW adoption. Meanwhile, age, farm income, skills training, and WUA membership were negatively correlated with the WP adoption. Nevertheless, proximity to a water source and upstream farmland location were positively correlated with the WP adoption. The WR adoption was positively associated with age but negatively correlated with the land holding size, upstream farmland location, and group participation factors. The cost–benefit analysis indicated that the WW irrigation scheme generated the highest economic return with the benefit-to-cost ratio schemes. The findings suggest that the WW irrigation technology would be deployed in the water management of other agricultural areas in the region to overcome the unfavorable geography and alleviate the local farmers’ disadvantageous economic conditions.
