Bibliometric analysis of global climate change and agricultural production: Trends, gaps and future directions

Climate change poses a significant threat to global food security, and a comprehensive understanding of its impact on agricultural production is needed. We analysed the Scopus data set between 1993 and 2023. China occupies the leading position in terms of climate change production, and the United States occupies the comprehensive strength position with the largest citation strength output. Notably, a substantial 29% annual publication increase between 2000 and 2015 was noted. Despite prevailing research on specific facets, a pronounced gap exists in global-scale studies focusing on the direct impact of climate change on agricultural production and yield, with a predominant concentration in regional analyses. Collaboration in this area continues to occur within developed nations, but the rate of growth at the international level is relatively low. In addition, the frequency of co-occurrence analysis of keywords revealed that climate change and sustainability are the focal keywords, but yield, food security, irrigation and rice production have yet to be identified. The results of this research will help in designing a policy for water resource management for irrigation planning and an adaptative food security management strategy and provide a feature research guide.
