The stifling burden of climate change on African public healthcare systems

Abstract

Background: Climate change is the greatest health threat of the 21st century to global health and primary health care. Despite being the least contributor to global greenhouse gas emissions, Africa is disproportionately facing severe impacts of climate change, particularly on its health systems which is already neglected and underfunded. The crisis poses a fundamental threat to human health by undermining healthcare infrastructure, straining workforce capacity, and diminishing global progress toward universal health coverage. It disrupts the physical environment, natural and human systems, and the functionality of healthcare systems, acting as a multiplier threat that jeopardizes and potentially reverses decades of health gains. The Sendai Framework, a roadmap for making vulnerable and marginalized communities safer and more resilient emphasizes the importance of investing in disaster risk prevention and reduction through both structural and non-structural measures, which are vital for enhancing socio-economic, health, and cultural resilience. This narrative review is based on the insights drawn from Climate Adaptation Research Program scholars across Africa. It explores the current and projected burden of climate change on the continent’s healthcare systems. It underscores the urgent need to integrate climate resilience into healthcare planning, fostering cross-sectoral collaboration, and ensures the sustainability of health systems amid escalating climate challenges.
Conclusion: The impacts of climate change on health represent a significant global challenge, demanding the establishment of robust and resilient healthcare systems. To mitigate the catastrophic and lasting effects of the climate crisis on healthcare and to prevent millions of climate-related deaths, it is essential to enhance resilience and preparedness.
