This work examines the effects of climate variability on tomato yield in Nigeria, focusing on key climate variables such as temperature, rainfall, humidity, and solar radiation. This review work synthesized existing literature, case studies, and scientific reports to assess how these climatic factors influence tomato growth, productivity, and susceptibility to pests and diseases. Findings revealed that extreme temperatures, both high and low, negatively affect tomato yield by disrupting flowering, fruit setting, and overall plant physiology. Fluctuating rainfall patterns, including prolonged droughts and excessive precipitation, contribute to soil erosion, water stress, and increased disease prevalence. High humidity levels promote fungal and bacterial infections, while low humidity accelerates water loss, reducing fruit quality. This review work equally highlights the socio-economic implications of climate variability, including reduced farmers incomes, food insecurity, and increased production costs due to the need for adaptation measures. Based on these findings, farmers are encouraged to adopt climate-smart agricultural practices such as improved irrigation techniques, drought-tolerant tomato varieties, and integrated pest management strategies. Additionally, government policies should support agricultural extension services, provide subsidies for climate-resilient farming inputs, and invest in research to develop adaptive strategies. Strengthening climate monitoring and early warning systems will further enable farmers to anticipate and respond effectively to climate variability. These interventions will contribute to stabilizing tomato yield, improving food security, and ensuring the sustainability of tomato farming in Nigeria.
