Climate Change and Agricultural Productivity in Nigeria (2000 – 2023).

Abstract:

This study investigated the effects of climate change on agricultural productivity in Nigeria from 2000 to 2023. Data were sourced from the Central Bank of Nigeria (CBN) Statistical Bulletin and the World Bank Climate Change Database. The study employed an ex post facto research design, and the data were analyzed using linear regression with an Error Correction Model (ECM). The findings revealed that climate change had a negative impact on agricultural output in Nigeria during the examined period. Based on these results, the study concludes that the detrimental effects of climate change on Nigeria’s agricultural sector highlight the need for immediate adaptive strategies. Key measures such as the adoption of climate-resilient crop varieties, enhanced irrigation systems, and sustainable farming practices are essential for building resilience and ensuring food security amid current environmental challenges. The study recommends prioritizing research, development, and dissemination of crop varieties engineered for drought and heat resistance. Additionally, farmers should be supported to adopt climate-resilient agricultural techniques capable of withstanding high humidity and associated crop diseases, including the use of humidity-tolerant crop varieties.
