Urban Governance and Resilience: Integrating Climate Change Mitigation and Microbial Infection Control Policies in Nigerian Cities

Abstract

Climate change and infectious diseases represent dual threats to public health and sustainable development in Nigeria’s rapidly growing urban areas. This paper examines the critical intersection between climate change mitigation initiatives and microbial infection control in Nigerian cities, arguing for integrated, nature-based, and infrastructure-sensitive approaches. Urbanization intensifies vulnerabilities through overcrowding, inadequate sanitation, pollution, and urban heat island effects, which amplify disease transmission risks while contributing to greenhouse gas emissions. We analyze how climate-driven factors,  including increased temperatures, erratic rainfall, flooding, and elevated atmospheric CO₂, influence the ecology, distribution, and virulence of pathogens, contributing to the resurgence of water-borne, vector-borne, and airborne infections. Concurrently, we assess mitigation strategies such as urban greening, sustainable waste management, renewable energy adoption, and green building standards for their potential co-benefits in reducing microbial exposure and enhancing urban resilience. The paper highlights case studies from Lagos, Abuja, and Port Harcourt to illustrate localized challenges and innovations. We conclude that synergistic policy frameworks, which combine emission reduction with public health protection, through improved surveillance, climate-responsive urban planning, community engagement, and investment in water, sanitation, and hygiene (WASH) infrastructure, are essential for building healthier, more sustainable, and climate-resilient Nigerian cities.
