article · Crop and Environment
Crop production is vital for global food security, yet plant diseases present major threats to agricultural productivity. Shifts in climate, particularly altered temperature, humidity, and rainfall patterns, drive changes in pathogen dynamics by enhancing disease virulence and transmission. Extreme weather events increasingly foster favourable environments for disease outbreaks. Furthermore, rising global temperatures expand the geographic footprint of pathogens into previously unaffected regions and crop species. These environmental shifts also undermine existing crop protection methods, highlighting a critical requirement for adaptive agricultural management. Addressing these interactions between shifting weather patterns and plant diseases provides fundamental insights needed to design robust counter-strategies, which can ultimately reinforce the resilience of worldwide crop production in the face of escalating environmental challenges.
Plant diseases directly threaten global food supplies, and shifting weather patterns exacerbate this risk by spreading infections to new areas. Understanding how changing environmental conditions affect pathogen behaviour helps farmers and policymakers prepare for emerging outbreaks, protect agricultural yields, and develop adaptable disease management practices essential for long-term food security.
The abstract discusses insights for developing adaptive disease management strategies to counter climate impacts on crops. Potential users include agricultural practitioners and crop protection specialists seeking to adapt control measures to changing pathogen ranges. Because the work is a review providing conceptual insights rather than a specific tool or product, it remains at an early, foundational stage of application.

Crop production stands as a pivotal pillar of global food security, but its sustainability faces complex challenges from plant diseases, which pose a substantial threat to agricultural productivity. Climate change significantly alters the dynamics of plant pathogens, primarily through changes in temperature, humidity, and precipitation patterns, which can enhance the virulence and spread of various plant diseases. Indeed, the increased frequency of extreme weather events, which is a direct consequence of climate change, creates favorable conditions for outbreaks of plant diseases. As global temperatures rise, the geographic range of many plant pathogens is expanding, exposing new regions and species to diseases previously limited to warmer climates. Climate change not only affects the prevalence and severity of plant diseases but also influences the effectiveness of disease management strategies, necessitating adaptive approaches in agricultural practices. This review presents a thorough examination of the relationship between climate change and plant pathogens and carefully provides an analysis of the interplay between climatic shifts and disease dynamics. In addition to insights into the development of effective strategies for countering the adverse impacts of climate change on plant diseases, these insights hold significant promise for bolstering global crop production resilience against mounting environmental challenges.
