Climate Change and the Sustainability of Rainfed Bean Production: A Scoping Review
Abstract
Climate change poses one of the greatest threats to the sustainability of rainfed agriculture in Latin America, where common bean (Phaseolus vulgaris L.) production is particularly vulnerable because of its high sensitivity to fluctuations in temperature and precipitation, as well as to extreme climatic events. This scoping review aimed to examine the evolution of scientific research on the impacts of climate change on the sustainability of rainfed common bean production in Latin America by identifying geographic and temporal research trends, methodological approaches, major scientific advances, knowledge gaps, and future research priorities. The review followed the Joanna Briggs Institute (JBI) methodological framework and the PRISMA-ScR reporting guidelines and included 154 peer-reviewed studies published in indexed journals. The evidence was synthesized by country, publication period, and methodological approach, encompassing field experiments, agroclimatic assessments, crop-simulation models, Geographic Information Systems (GIS), remote sensing, review articles, meta-analyses, and farmer surveys. The results revealed that scientific production was concentrated primarily in Mexico and Brazil, whereas research in the remaining Latin American countries remained limited and geographically fragmented. Over time, the field evolved from studies focused primarily on crop physiology and genetic improvement toward multidisciplinary approaches integrating climatic, agronomic,…
