How Dimensions of Climate Change Awareness Relate to Advanced Technology Adoption in Rice Production in Central Coastal Vietnam

Climate change is raising production risks for smallholder rice farmers in coastal Central Vietnam, but adoption of advanced agricultural technologies remains uneven. Guided by the Theory of Planned Behavior and Diffusion of Innovations, this study examines climate change awareness as a multidimensional factor associated with advanced technology adoption. Using cross-sectional survey data from 279 rice-farming households in Thua Thien Hue province and binary logistic regression, it finds that climate adaptation knowledge (OR = 2.948, p = 0.003) and climate change perception (OR = 2.676, p = 0.013) are positively associated with adoption, while climate risk worry is only marginally positive (OR = 1.262, p = 0.074). Agricultural impact awareness is negatively associated with adoption (OR = 0.465, p = 0.019). The results suggest that awareness alone is insufficient; policies should combine risk communication with practical training, locally appropriate support, and investment-risk reduction.
