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.

MACROECONOMIC AND CLIMATIC DETERMINANTS OF GINGER PRODUCTIVITY IN NIGERIA (1961 – 2016)

Çalışma,
1961-2016 yılları arasında Nijerya'daki zencefil üretkenliğinin makroekonomik
ve iklimsel belirleyicilerini analiz etmektedir. Zencefil verimliliğini tahmin
etmek için Malmquist verimlilik endeksi kullanılmış iken, zencefil
üretkenliğinin uzun dönem ve kısa vadeli belirleyicilerini hesaplamak için ise   Otoregresif
Dağıtık Gecikme Modeli kullanılmıştır. Sonuçlar zencefil üretkenliğinin
incelenen sürede marjinal bir artış yaşadığını ortaya koymaktadır. Sıcaklık ve
yağış, iklim değişikliğinin güçlü etkisini gösteren zencefil üretiminde uzun
vadede sırasıyla olumsuz ve olumlu bir etki yaratmıştır. Bu nedenle, Nijerya'da
zencefil üretiminin artması için sermaye sağlanması, sulama tesislerinin
bulunması yoluyla iklim değişikliğinin etkisinin yönetilmesi için çaba gösterilmesi
gerekmektedir.
