Abstract

This paper examines the relationship between greenhouse gas emission and rice production in Nigeria using the Autoregressive Distributed Lagged (ARDL) bounds test. Annual time series data of four selected variables rice output, rice yield, rice harvested area, fertilizer usage and greenhouse emission (CH4) in rice production was used over the period 1961 to 2017. Empirical results provide evidence of longrun relationship between greenhouse gas emission and rice production in Nigeria. The result of the estimated elasticities of both the shortrun and long run analysis indicate that all the variables except fertilizer usage in the long run, significantly explain changes in greenhouse gas emission in rice production. The findings recommend the need to adopt new approaches to rice cultivation that will boost productivity using less energy and land resources in order to decrease GHG emissions. The use of improve seed varieties that would increase yield using less land area, fertilizer application, water usage and chemical in production could also be a good strategy of reducing GHG emission in rice cultivation which has impact on atmospheric pollutions and global warming
