Abstract: The effects of climate change represent one of the biggest threats to agriculture today. With the aim of identifying the factors that influence farmers to choose and implement adaptive methods of crop production in Central Chile, we noted a set of adaptation practices based on literature review and consultation to a panel of experts. Using a hurdle model, we determined the socioeconomic and farm characteristics that affect, first, the decision to adapt, and next, the intensity of adaptation. With respect to the decision to adopt, relevant variables were found to be security of land tenure, which increased the probability of positive decision-making by 21%, and access to weather information, which increased the probability by 30%. To identify the variables affecting the intensity of adoption, a zero-truncated negative binomial regression was estimated. The results show that the number of practices adopted has a significant association with the location of a farm and the main crops produced. Membershi in organizations or associations, measures of social capital, increase the intensity by 72.2% and security of land tenure by 44.5%. Years of experience in agriculture and the amount of income obtained from crops the previous season also had a positive impact. Empirical results confirm that from the perspective of climate change adaptation policy, the most effective way to help farmers make the decision to adapt is improving access to information, and the most effective way to increase the intensity of adaptation is to encourage social networking among producers.
