Abstract
This study was carried out to assess the dynamics of greenhouse gas emissions and crop production in
Nigeria. Annual time series data from 1981 to 2020 were used. Data were collected from the Food and
Agriculture Organization and World Bank records. Descriptive statistics, Johansen Co-integration and
Vector Error Correction Model were employed to analyze the data. Using Augmented Dickey Fuller test,
the result indicated that greenhouse gas and crop production were integrated of order one; this showed that
the variables exhibit random walk. The result of the Johansen Co-integration test showed that the trace
statistics (74.35981) was greater than the critical value at 0.05 significance level (69.81889). This implied
the existence of co-integration between the variables (greenhouse gas emissions and crop production). The
long run result of the VECM showed that, the coefficient of greenhouse gas (-32.416) was negative and
statistically significant at 1% which indicated the existence of long run effect of greenhouse gas on crop
production. The study therefore recommended that it is important to educate farmers through proper
extension services on how mitigate the long-term impact of greenhouse gas emission. This could include
measures such as reducing greenhouse gas emissions.
