Abstract: Groundnut is one of the important oil-bearing leguminous crops that contribute significantly to the food and nutrition security of the poor, particularly in Nigeria where it is widely grown. However, climate has an exquisite role in its production which often varied within the year across the globe. Using data for 1200 groundnut farming households from the General Household Survey wave 4 and historical data for temperature, rainfall and groundnut yield in Nigeria from 1981- 2019 gotten from Nigeria Meteorological Agency and Food and Agricultural Organisation respectively; this study assessed the impacts of climate change on mean yield and Net revenue for groundnut production in Nigeria using Feasible Generalized Least Square and Structural Ricardian Approach respectively. This study revealed that 1 ℃ increase in temperature increased groundnut yield and net revenue by 3.316kg and N516.800 per hectare respectively while 1mm increase in rainfall reduced groundnut yield and net revenue by 0.505kg and N516.800 per hectare. The simulated impact of climate change on net revenue using Canadian Climate Change model revealed that the Net revenue generated from groundnut production will reduce by 8.36% with 6.7 ℃ increase in temperature and reduce by 0.60% with 18.4mm decrease in rainfall by 2100. Therefore, proactive and urgent measures should put in place to aid Nigerian groundnut farmers adapt to the present and looming threats of climate change effects on groundnut production.
