Abstract:
The study analyzed the effects of greenhouse gas emissions on Cereal Crop production in
Nigeria using secondary data from 1990 to 2023. The data were analyzed using Autoregressive
Distributed Lag Model (ARDL). The study revealed that GHG emissions have significantly
fluctuated, with carbon dioxide and methane emissions increasing substantially. Cereal crop
production exhibited varying trends, with maize and rice showing growth, while wheat
production remained inconsistent. The result showed that a long run relationship exists between
cereal crop production, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O)
emissions. Further, the result revealed that in the short run, a unit increase in carbon dioxide,
methane and nitrous oxide emissions decreased maize production by 6.6%, 13.5% and 3.7%
respectively, wheat by 17.2%, 28.8% and 7.4% respectively while carbon dioxide and methane
reduce rice by 9.6% and 15.1%. In the long run, a unit increase in carbon dioxide, methane and
nitrous oxide emissions will decrease cereal production. Specifically, maize will fall by 6.6%,
13.2% and 3.7% respectively, rice by 1.4%, 6.7% and 2.8% respectively while only CO2
emission reduces wheat by 4.6% in the long run. In general, methane emissions had the largest
detrimental short and long run effects on cereal crop production. The study recommends the need
for government to encourage the adoption of environmentally friendly farming techniques that
will reduce greenhouse gas emissions such as conservation tillage, crop rotation and
agroforestry. |
