Macroeconomic and Climatic Determinants of Ginger Productivity in Nigeria (1961-2016)

The study analyzed the macroeconomic and climatic determinants of ginger productivity in Nigeria from 1961 – 2016. The Malmquist productivity index was used to estimate the productivity of ginger while Auto Regressive Distributed Lag Model was used to estimate the long-run and short-run determinants of ginger productivity. The results reveal that the productivity of ginger has been experiencing a marginal increase over the period studied. Temperature and rainfall had a long run negative and positive impact respectively on ginger production showing the strong influence of climate change. Capital had both positive and negative impacts on the productivity of ginger in the long run and short run. It is therefore recommended that the availability and accessibility of capital are very essential for the increased production of ginger in Nigeria and there should be efforts to manage the impact of climate change through the availability of irrigation facilities.
