This study investigated the opinion of undergraduates on the influence of climate change on food security in Lagos State. Quantitative and qualitative methods were utilized to conduct a descriptive survey. Three research questions were raised to guide the study. Data was gathered using structured questionnaire and a Focus group discussion. The population of the study is 1149 undergraduates from which a sample size of 296 was drawn using a multistage sampling procedure. A validated questionnaire was utilized to obtain data from the participants. Mean and Standard deviation were used to analyze data. According to the results, human activities are the major causes of climate change in the present world. The influence of climate change on food security includes high food prices, low agricultural output, increased pest attack, food spoilage and contamination. The study revealed that man-made efforts can help prevent local climate change through promoting environmental health thereby encouraging food security. Such efforts include investing in energy efficient appliances, reducing water waste, avoiding open burning and driving less. Findings also revealed that growing a vegetable garden in our homes and planting at least one tree might help to alleviate the environmental hazard of climate change. Conclusions were reached, and the study suggests that appropriate measures should be put in place to ensure environmental friendly practices to prevent further degradation.
