Understanding smallholder farmers' adaptation behaviors through climate change beliefs, risk perception, trust, and psychological distance: Evidence from wheat growers in Iran.

Climate change (CC) poses severe threats to the agriculture sector in developing countries. ‏Increasing empirical evidence has confirmed that adaptation strategies to CC at the farm level can significantly reduce the negative impacts of CC and minimize vulnerability. Consequently, understanding adaptation to CC has become a major concern for farmers to facilitate adaptation actions and assist them in improving their adaptive capacity. In this context, this study investigated the most prominent psychological drivers of, and impediments to, adaptation responses. To this end, 350 farmers from Kermanshah district in western of Iran were selected as our sample through a multi-stage, stratified, random sampling method. Structural equation modeling found a complex relationship between overall CC belief, risk perception, psychological distance, trust and risk salience, and farmers' adaptation behaviors. Climate risk perception, trust, and psychological distance were much more effective in driving farmers' adaptation behaviors. The findings yield recommendations for public policy and risk communication that could encourage adaptation behaviors among Iranian farmers.
