Abstract
This paper aims to investigate farmersʼ intention and behavior in response to climate change associated with salinity intrusion and drought in the Mekong Delta of Vietnam. The cross-section data were obtained from in-depth interviews with 361 rice farmers in the Mekong Delta, Vietnam. Structural equation modeling was employed to explore the relationship among the constructs based on constructs in the theory of planned behavior which deals with farmersʼ adaptation intention and their behavior. The results indicate that rice farmers in the delta are more likely to intend to respond when they have a higher perception of climate change and perception of climate change adaptation. Perceived behavioral control, subjective norm, and trust in public adaptation are also found to significantly influence farmersʼ intention to perform climate change adaptation. Furthermore, the results show that not only the intention but also subjective norm significantly and directly motivate their behavior in response to climate change while those factors driving intention except for perceived behavioral control indirectly influence their behavior in response to climate change.
