Understanding Polycrisis: Definitions, Applications, and Responses

This paper compares conceptualizations of the term “polycrisis,” raising questions about the key aspects of different definitions while stressing a convergence in critical features. It conceives a polycrisis as a state in which multiple, macroregional, ecologically embedded, and inexorably interconnected systems face high – and advancing – risk across socioeconomic, political, and other dimensions. After […]

Global Food Security in a Turbulent World: Reviewing the Impacts of the Pandemic, the War and Climate Change

The authors explore how the COVID-19 pandemic, the Russia–Ukraine war, and climate change have jointly disrupted global food security. Drawing on recent empirical evidence, the paper examines the mechanisms through which each shock has affected the four key dimensions of food security: availability, access, utilization, and stability. By highlighting the compounding effects of these overlapping

The State of Global Catastrophic Risk Research: A Bibliometric Review

This paper presents a systematic bibliometric analysis of the expanding literature on global catastrophic risk (GCR) and existential risk (ER). Based on 3,437 documents, the authors identify ten major research clusters, including key drivers such as artificial intelligence, climate change, and pandemics. The metadata indicate that approximately 150 GCR/ER-related publications are produced annually. The analysis

Cascading Failure, Financial Network and Systemic Risk

This paper addresses the challenge of accurately measuring systemic risk by introducing a novel indicator, Expected Shortfall Rank (ESRank), which accounts for cascading failures and network effects often overlooked in traditional models. Using LASSO to construct tail risk networks among financial institutions and ΔCoES to simulate contagion dynamics, the study develops a general cascading failure

Beyond the Buzzword: Rethinking Polycrises in Public Policy and Administration Research

The author examines the use of the polycrisis concept in public policy and administration research, highlighting its potential for addressing complex challenges but noting a frequent lack of conceptual clarity and analytical depth. Polycrises are often treated as static and uniform, despite their dynamic and multifaceted nature. To strengthen its application, the author proposes clearer

Systemic Contributions to Global Catastrophic Risk

This article examines two distinct but related approaches to the global risk landscape: one explores how risks emerge from complex global systems, while the other focuses on worst-case outcomes. The authors present a framework that connects these perspectives, highlighting how emergent properties of the global system—such as hazards, amplification, vulnerability, and latent risks—drive the potential

How Can Aid for Trade Support the Resilience of the Least Developed Countries in the Face of Polycrisis?

This article examines the potential of Aid for Trade (AfT) as a tool for building resilience in developing countries and least developed countries amid the growing complexity of global polycrisis. Drawing on evidence from a range of AfT-supported initiatives, it highlights AfT’s capacity to enhance resilience at both macro and micro levels. However, the impact

Dynamics of the Polycrisis: Temporal Trends, Spatial Distribution, and Co-occurrences of National Shocks (1970–2019)

The authors investigate the evolving nature of global crises by analyzing the temporal trends, geographic distribution, and co-occurrences of shocks across 175 countries from 1970 to 2019. Their findings reveal that shocks have become increasingly co-occurring until 2000, particularly involving conflict, climate, and technological disruptions, followed by regionally varied patterns of stabilization or decline. By

Systemic Management Practices—Enabling Local Governments to Adapt in Response to Complexity

The authors explore the impact of accelerating change and increasingly complex global and local challenges on the city as a complex socio-ecological service ecosystem (SES) and its capacity to ensure sustainability or ecosystem health. Drawing on systems science and the service ecosystems perspective, they present a framework for systemic management that prioritizes holistic, integrative, adaptive,
