This study investigates the impact of climate change on cocoa crop production in Nigeria from 1980 to 2022 using country specific data on climate change factors like rainfall, temperature, and gas emissions; and cocoa crop output. We relied on the translog analytical technique of Christensen, Jorgenson and Lau that allows for greater flexibility in measuring environmental relationships compared to other traditional measurement techniques. Our finding suggests that at their individual levels, rainfall and carbon(IV)oxide exhibited positive output pressure on cocoa production. Within the same measures, a single percentage rise in the temperature level and gas flared quantity will negatively affect cocoa output to the value of 51% and 76% loss respectively that are statistically significant. However, deepening temperature and carbon(IV)oxide simultaneously deepen cocoa output positively within the region of 5% and 84% rise and statistically significant at one percent level of significance. Also, we found that rainfall and temperature combined, produces an insignificant positive impact on cocoa output of nearly 87% at every 10%rise in combined rainfall and temperature and the combined effect of rainfall and gas flared of say 10% increase had a combined impact of at least 20% increase in cocoa output that is not significant. This paper recommends cocoa production ranging to mitigate our country specific climate aided impact of gas flaring from oil production areas added to climate related planning for Nigeria in years following this report.
