Climate Smart Agriculture (CSA) seeks to sustain or improve agricultural yields while mitigating climate change. The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) has made substantial investments in developing and scaling CSA programs in developing countries. Using a multi-country dataset, this paper runs two complementary analyses. The first uses a double/debiased machine learning approach to estimate the impact of participating in a CCAFS CSA program on household food security. I estimate this impact for the entire sample and within three sub-samples, which categorize households according to their CSA adoption strategy (i.e., non-adoption, specialized adoption, or diversified adoption). Results indicate that the probability of a household being food secure is 6.0 percentage points higher (p\u003C0.05) if it participated in a CCAFS program. The food security benefits ofCCAFS program participation are most clearly demonstrated among households that adopted a diverse set of CSA practices, where CCAFS training increased the probability of being food secure by 9.7 percentage points (p\u003C0.05). On the other hand, the food security benefits of CCAFS training were negligible among households that did not adopt CSA practices or adopted a specialized set of practices. The second analysis combines traditional machine learning tools with future climate data to predict and compare the future food security ofCCAFS program participants and non-participants. Results show that participating households are more likely tobe food secure than non-participating households across all periods. Overall, the food security gap between participating and non-participating households is expected to increase over time.  \nAcknowledgements  \nI would like to thank my supervisors, Dr. Marty Luckert and Dr. Bruno Wichmann, for their support and guidance throughout my degree. Marty, thank you for taking a chance on me when Ijoined your biofuels group in 2019, and for advocating for me ever since. The growth I’ve experienced as a student and researcher wouldn’t have been possible without your leadership. Bruno, thank you for your creative genius, passion for econometric methods, and for introducing me to the fascinating world of machine learning. Lastly, thank you both for the opportunity to study a topic that aligns with my interests and future goals. I am excited for what will come next.  \nI would also like to thank the teachers and professors who inspired me to pursue a graduate degree. I couldn’t be happier with my field of study and am honoured to be following in your footsteps. Additional thanks go to Dr. Henry An and Dr. Brent Swallow for their contributions to my thesis examination.  \nThis work was implemented as part of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) led by the Alliance Biodiversity International and the International Center for Tropical Agriculture (CIAT), which is carried out with support from CGIAR Fund Donors and through bilateral funding agreements.
