This study examines how a wide range of social-psychological factors, including perceived risks, beliefs in climate change occurrences and consequences, belief in human ingenuity and trust in institutions, could influence farmers' decisions in taking different climate change adaptation and mitigation strategies. We found that farmers who believe in climate change occurrences and consequences tend to adopt mitigation strategies than others, while those who believe in perceived risk associated with climate threats are more likely to have positive attitudes toward adaptation. Moreover, belief in human ingenuity to tackle climate change lessens farmers' decisions to adopt adaptation and mitigation measures. Therefore, policymakers should improve farmers' belief in human ingenuity, the occurrences of climate change and climate change consequences to effectively motivate them toward climate change adaptation and mitigation.
