The journal publishes original research, comprehensive reviews, and case studies on topics such as crop science, sustainable farming practices, agricultural economics, agri-business management, soil science, and rural development. By fostering interdisciplinary dialogue among researchers, practitioners, and policymakers, it provides a global platform for innovative solutions that promote food security and sustainable development.</p>https://gphjournal.org/index.php/ar/article/view/2076EFFECT OF CLIMATE CHANGE ON SOYA BEANS (Glycine max) OUTPUT IN NIGERIA2025-09-13T10:36:37+00:00Audu, I. Anoreplygphjournals@gmail.comBulus, G.noreplygphjournals@gmail.comDANJI, M. B.noreplygphjournals@gmail.com<p>The study examined climate change effects on soya beans output in Nigeria. Data were collected from the Food and Agriculture Organization (FAO) and the Nigerian Meteorological Agency (NIMET) from 1981-2018. The effect of climate change was analyzed using Autoregressive Distributed Lag Bound approach, Error Correction Model and Augmented Dickey– Fuller tests for stationarity test. On the effects of climatic variables on soya beans output, the coefficient of multiple determination (R<sup>2</sup>) 0.7965, shows that about 79.65%, of the variations in soya beans output was explained by the climatic variables. F-statistics of 24.27 is significantly higher than the lower bound of 2.9 and the upper bound of 3.8 at 5% level. This indicates that there is a long run relationship between soya beans output and the climatic variables in the model. The ECM value of soya beans output is -0.126. The magnitude of the coefficient estimate of ECM suggests that 12.6% of the disequilibrium caused by previous years’ shocks converges back to the long-run equilibrium in the current year. This reveals that the speed of adjustment will adjust to the long-term equilibrium. The study recommends the need for policy makers to establish temperature monitoring systems and thresholds to preemptively address warming that could negatively impact soya beans output.</p>2025-09-13T10:36:37+00:00##submission.copyrightStatement##
