An analysis of crop choice: Adapting to climate change in South American farms
This paper explores how South American farmers adapt to climate by changing crops. We develop a multinomial logit model of farmer's choice of crops. Estimating the model across 949 farmers in seven countries, we find that both temperature and precipitation affect the crops that South American farmers choose. Farmers choose fruits and vegetables in warmer locations and wheat and potatoes in cooler locations. Farms in wetter locations are more likely to grow rice, fruits, potatoes, and squash and in dryer locations maize and wheat. Global warming will cause South American farmers to switch away from maize, wheat, and potatoes towards squash, fruits and vegetables. Predictions of the impact of climate change on net revenue must reflect not only changes in yields per crop but also crop switching.
