From global challenges to specific solutions: climate change impacts on agriculture with a focus on sorghum through bibliometric analysis

Abstract

Climate change significantly threatens global agriculture, with rising temperatures, erratic precipitation, and extreme weather events undermining crop productivity and food security. This study employs bibliometric analysis to explore the research landscape on sorghum, a climate-resilient crop, using 1,040 articles from the Web of Science Core Collection (1990–2023). Sorghum’s resilience to drought, heat, and salinity positions it as a viable alternative to traditional cereals in climate-stressed regions. The analysis highlights the USA, India, and Australia as leading contributors, with prominent institutions like the International Crops Research Institute for the Semi-Arid Tropics and Kansas State University driving innovations. The top journals, including Agricultural and Forest Meteorology and Sustainability, and prolific authors, such as Prasad PVV and Sultan B, underscore the field’s vibrant research ecosystem. Emerging themes, including drought tolerance, genetic improvement, and food security, reflect the crop’s growing importance in sustainable agriculture. This study provides a comprehensive overview of research trends and offers actionable insights for future studies and policy development. It also aids researchers in selecting publication outlets and fostering collaborations, emphasizing sorghum’s potential to mitigate climate change impacts and ensure food security.
