This study examines the impact of climate change adaptation on food productivity in Ethiopia, focusing on the decisions of farm households. The research uses a simultaneous equations model with endogenous switching to account for heterogeneity in adaptation decisions and unobservable characteristics of farmers and their farms. The findings indicate that access to credit, extension, and information are the main drivers of adaptation. Adaptation increases food productivity, and farm households that did not adapt would benefit the most from it. The study also finds that adaptation strategies, such as changing crop varieties and soil conservation, significantly affect food productivity. The results show that adaptation to climate change increases food productivity, with the impact being smaller for those who actually adapted compared to those who did not. The study highlights the importance of information and credit access in enabling adaptation. It also shows that adaptation strategies can help vulnerable farm households improve their food security. The study concludes that adaptation to climate change is crucial for food security, and that policies promoting access to credit and climate information can help farmers adapt more effectively. The results suggest that adaptation strategies are particularly important for the most vulnerable farm households, as they can help close the productive gap with less vulnerable households. The study also emphasizes the need for further research on the behavioral aspects of adaptation and the effectiveness of different adaptation strategies.This study examines the impact of climate change adaptation on food productivity in Ethiopia, focusing on the decisions of farm households.
