The study evaluated the economic impacts of climate change on agriculture and food security in South-West, Nigeria. Three specific purposes and three research questions guided the study. A descriptive survey research design was adopted. It was carried out in South West, Nigeria (Lagos, Ogun, Oyo, Osun, Ondo, and Ekiti States). The population for the study was 660 farmers randomly selected from the six states in South-West region of Nigeria and sampled using accidental sampling technique. Structured questionnaire was used for data collection and it was face validated by three experts. Cronbach alpha reliability method was used to ascertain the internal consistency of the instrument and a reliability coefficient of 0.78 was obtained which showed that the instrument was reliable and effective for the data collection. Data collection was carried out by the researcher and six research assistants. Mean and standard deviation were used to analyze the data collected. The findings revealed thirteen (13) impacts of climate change on agriculture and food security in South West region of Nigeria; eight (8) adaptive strategies adopted by farmers in South West region of Nigeria to mitigate the impact of climate change; and twelve (12) sustainable agricultural practices that can be adopted in mitigating the impacts of climate change. Based on the results obtained, the study concluded that it is essential to develop and implement effective strategies to mitigate the economic impacts of climate change on agriculture and food security in the South West, region of Nigeria. It was therefore recommended that the government and other stakeholders should promote climate-smart agriculture practices, such as conservation agriculture, agroforestry, and crop diversification to enhance agricultural productivity and resilience to climate change among others.
