Environmental Governance and Microbial Infection Control in Nigerian Ecosystems: Addressing the Policy Implications of Climate Variability

Abstract

Climate variability has emerged as a critical determinant of microbial infection dynamics, particularly in tropical regions where environmental conditions strongly influence pathogen survival, transmission, and evolution. Nigeria, characterized by diverse ecosystems ranging from mangrove swamps and tropical rainforests to savannahs and semi-arid zones, is highly vulnerable to climate-induced changes that affect the distribution and burden of infectious diseases. Variations in temperature, rainfall patterns, humidity, flooding, and drought have been shown to alter microbial ecology, vector populations, water quality, and human–environment interactions, thereby reshaping infection patterns across communities. This review examines the complex interactions between climate variability and microbial infections within Nigerian ecosystems, with emphasis on bacterial, viral, parasitic, and fungal pathogens of public health importance. It highlights how climate-driven environmental changes influence pathogen persistence, host susceptibility, transmission routes, and outbreak seasonality. The paper further discusses the implications for disease surveillance, public health preparedness, and ecosystem management, while identifying knowledge gaps and research priorities necessary for developing climate-resilient health strategies in Nigeria.
