This journal article is aimed at examining, through literature search, the impact of climate change on food security in Nigeria with a view to making suggestions on strategies to mitigate the impact of climate change on the environment generally and food security in particular. Some of the suggested strategies include: reducing the emission of greenhouse gases by stopping deforestation; use of high yield and disease-tolerant crops and crops adaptable to extreme weather conditions; farmers to cultivate their crops when rains are expected rather than during ‘planting seasons’. The paper concludes that the environmental degradation caused by climate change has affected agricultural production in sub-Saharan Africa in general and Nigeria in particular and it is imperative that it is tackled.
