Polycrisis Resilience in the 21st Century: Reducing human and systemic vulnerability to interconnected global crises, 2026–2100

Polycrisis Resilience is a framework for understanding and reducing vulnerability to the interconnected global crises shaping the twenty-first century, including climate change, pollution, poverty, resource insecurity, conflict, institutional fragility, technological dependence, and infrastructure weakness. This report argues that the severity of these crises depends not only on the hazards themselves but also on the vulnerability of the populations and systems exposed to them. Drawing on evidence from 217 economies and public international datasets, it shows that many of the vulnerabilities associated with the global polycrisis are strongly linked to development outcomes such as access to energy, health care, sanitation, education, digital connectivity, and effective institutions. The report introduces the H Heuristics Polycrisis Resilience Framework, which defines resilience as the capacity of individuals, communities, institutions, economies, and interconnected systems to anticipate, withstand, adapt to, recover from, and reduce vulnerability to multiple interacting crises. The framework identifies ten development pathways, including clean energy transition, technology diffusion, climate adaptation, human development, infrastructure strengthening, public health, institutional capacity, economic diversification, food and water security, and digital infrastructure. These pathways are presented as mutually reinforcing mechanisms for reducing both human and systemic vulnerability. Using century-scale scenarios for 2026-2100, the report demonstrates how sustained development can substantially reduce exposure to interconnected risks. It concludes that Polycrisis Resilience is fundamentally a long-term strategy of vulnerability reduction, in which development, technological progress, environmental improvement, and institutional strengthening work together to improve human well-being while reducing the potential for cascading global crises.
