This study analytically examines the relationships between carbon emissions, population growth, and agricultural GDP in Nigeria from 1977 to 2022. The data were sourced from the World Bank and the Food and Agriculture Organization (FAO). The data were analyzed using econometric techniques (Ordinary Least Squares (OLS) regression, Johansen cointegration, and Granger causality tests). The results show a statistically significant positive relationship (P<0.05) between AGDP and population growth. A 1% increase in population growth could increase agricultural GDP by approximately 2.3%. In contrast, carbon emissions although positive but statistically shows insignificant impact on AGDP. The Cointegration analysis result shows a stable long-run equilibrium relationship among the variables in the model. Similarly, Granger causality tests reveal a unidirectional causal relationship from AGDP to carbon emissions, suggesting that economic growth in the sector enhance environmental pollution by increasing carbon emission, no other way round. Based on these findings, we recommend policy interventions focused on dissociating agricultural growth from its environmental impact through the adoption of climate-smart technologies and the incorporation of emission control strategy into national agricultural development plans.
