The Development Economics of Polycrisis Resilience

Abstract

This report introduces a research framework that examines economic development as a foundational mechanism for reducing vulnerability to the interconnected risks of the twenty-first century. It argues that the human consequences of the global polycrisis, including climate change, economic instability, health shocks, food and energy insecurity, and conflict, are shaped not only by hazards themselves but by underlying levels of income, infrastructure, institutional capacity, technology access, health, and education. Development is therefore conceptualized as a process of building adaptive capacity and systematically reducing structural vulnerability.

The framework identifies six complementary pathways through which development enhances resilience: economic growth and poverty reduction; infrastructure and clean energy development; technology diffusion and productivity; human capital and public health; environmental and climate resilience; and institutional and financial capacity. It further proposes that global economic convergence can serve as a resilience mechanism by expanding access to modern capabilities across lower-income regions, while emphasizing that convergence must be environmentally sustainable and institutionally inclusive. A development-resilience feedback loop is presented in which rising capabilities reduce vulnerability, improve human outcomes, and strengthen future development potential.

To guide future research, the report outlines priority questions related to resilience returns, development thresholds, pathway interactions, financing mechanisms, and long-term global convergence. It also proposes the development of a Polycrisis Resilience Index to measure structural resilience across countries and regions. The central hypothesis is that accelerating and directing sustainable development in vulnerable regions may represent one of the highest-leverage strategies for reducing cumulative human suffering and strengthening societal resilience throughout the twenty-first century.

Key findings

1. Vulnerability is largely a development outcome. Disaster mortality, hunger and the economic cost of shocks fall steeply with income, infrastructure, education and institutional quality.
2. Six complementary pathways carry the effect: growth and poverty reduction; infrastructure and clean energy; technology diffusion; human capital and health; environmental and climate resilience; and institutional and financial capacity. Their effects interact strongly, so diagnosis and sequencing matter.
3. Global convergence is a resilience mechanism. A world with far more people holding reliable energy, health care, skills, digital access and capable institutions can absorb shocks that would overwhelm today's. The gaps remain large: 655 million people lack electricity and about 2.1 billion lack clean cooking.
4. Development and resilience form a feedback loop. Capabilities reduce vulnerability, lower vulnerability reduces suffering, and a healthier, more secure population can develop further. The loop runs in reverse as a trap when shocks erode the gains.
5. The direction of development matters as much as its speed. Growth that raises pollution, ecological degradation or climate exposure creates new vulnerabilities. Sustainable convergence, built on clean energy, resilient infrastructure and inclusive institutions, is the objective.
6. Finance is the limiting factor where returns to resilience are highest. International public adaptation finance (about US$26 billion in 2023) is a small fraction of estimated needs.

Glossary

Polycrisis

A condition in which crises in multiple global systems become causally entangled in ways that significantly degrade humanity's prospects (Cascade Institute).

Resilience

The capacity of people, communities and systems to anticipate, absorb, adapt to and recover from shocks, and where possible to transform in response to them.

Adaptive capacity

The set of resources, institutions and knowledge available to respond to a shock or stress.

Vulnerability

The propensity to be harmed by a shock, a function of sensitivity and adaptive capacity.

Exposure

The presence of people, livelihoods and assets in places that could be adversely affected by a hazard.

Convergence

The tendency of poorer economies to grow faster than richer ones, narrowing gaps in income per capita; conditional convergence holds after controlling for country characteristics, unconditional convergence does not require this.

Growth premium

The difference between a country's per-capita growth rate and that of the frontier.

Technology diffusion

The spread of existing technologies and practices across firms, regions and countries.

Poverty trap

A self-reinforcing mechanism that perpetuates poverty, such as asset thresholds or nutrition-productivity links.

Adaptive social protection

Safety-net systems that can expand automatically or rapidly in response to shocks.

Parametric insurance

Insurance that pays out on a pre-defined trigger (such as rainfall or wind speed) rather than on assessed loss.

Mini-grid

A small-scale local electricity network, typically solar-based, serving a community or enterprise cluster.

PPP

Purchasing-power parity: price adjustments allowing comparison of incomes across countries.

PRI

The proposed Polycrisis Resilience Index.
