Climate Change and Its Implications for Community Health: Challenges and Strategies for Adaptation

Climate Change and Its Implications for Community Health: Challenges and Strategies for Adaptation Climate change is an existential threat to public health worldwide, producing immediate and long-term impacts on mortality and morbidity through direct pathways (heat waves, extreme weather events) and indirect pathways (air quality deterioration, food and water insecurity, vector-borne disease spread, population displacement, mental health burden). Vulnerability and resilience to these health impacts vary widely across and within countries, driven by socioeconomic context, health system capacity, governance, and exposure. This paper synthesizes current evidence from global assessments and peer-reviewed literature, proposes a theoretical framing combining the Social Determinants of Health and the Vulnerability–Resilience frameworks, presents a comparative analysis between developing and developed countries using global datasets (heat-related mortality and health expenditure indicators), and outlines evidence-based adaptation strategies at community, health system, and policy levels. Key findings: (1) heat-related mortality and many climatedriven health risks are increasing; (2) low- and middle-income countries (LMICs) face disproportionate burdens due to lower adaptive capacity; (3) integrated adaptation (health system strengthening, early warning, social protection, urban planning) produces co-benefits for health and development; and (4) financing and governance gaps remain major barriers to effective climate–health adaptation. The paper concludes with prioritized recommendations and a research agenda.
