Title of the paper : Climate Change, Microbial Ecology, and Migration: The Hidden Link through Water

Abstract: Climate change is increasingly recognized as a driver of hydrological instability, altering global rainfall patterns, water temperature, and freshwater availability. These changes directly influence the abundance, diversity, and distribution of microorganisms in aquatic environments. Water, being both a habitat and a vehicle for microbes, serves as a key medium through which environmental change translates into public health risk. Droughts, floods, and warming waters modify microbial community structures, often favoring pathogenic species that lead to outbreaks of cholera, leptospirosis, and other waterborne diseases. These microbial disruptions not only threaten health and livelihoods but also act as precursors to human migration, forming a hidden microbial chain linking climate stress, disease, and displacement. This review explores the complex relationship between climate change, water microbiology, and human migration through selected case studies, current monitoring approaches, and integrative frameworks such as the One Health perspective.
