Increasing global temperatures, altered precipitation patterns, and extreme weather events profoundly impact soil microbial communities and pathogen dynamics. The current chapter examines the intricate relationships between climate change and soil ecosystems, particularly on pathogen biodiversity and ecosystem functions. Research demonstrates that climate warming leads to decreased microbial diversity and altered soil biogeochemical conditions, significantly impacting ecosystem multifunctionality. Through analysis of temperature, precipitation, extreme weather events, CO2 levels, and soil moisture variations, this work explores their influence on pathogen behavior, distribution, and virulence. Additionally, it addresses agricultural sustainability and food security implications, presenting adaptation strategies and management approaches for mitigating climate change impacts on soil ecosystems. The chapter synthesizes current research on soil-borne pathogen responses to climate change and provides insights into future challenges and opportunities for sustainable agriculture under changing climatic conditions.
