there are emerging frameworks for polycrisis modeling, though they are relatively new and interdisciplinary. The most prominent approaches rely on systems thinking and complexity science to map how multiple, distinct crises interact and amplify one another.
Currently, there isn’t a single, universally standardized software package, but rather a set of conceptual frameworks and modeling techniques that researchers and institutions use. The most significant developments come from the Cascade Institute and recent academic work published in journals like Global Sustainability.
Here are the key frameworks and approaches currently in use:
1. The Polycrisis Patterns Framework (System Archetypes)
A leading conceptual framework was recently proposed by researchers including David Collste and Cristina I. Apetrei. It adapts classic system archetypes from system dynamics to describe how crises interact. Instead of modeling every variable, this framework identifies recurring structural patterns:
- Converging Constraints (Limits to Growth): Describes how growth in one system (e.g., economic production) hits physical limits (e.g., climate boundaries), which then triggers crises in other systems that further constrain the original system https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1.
- Deepening Divides (Success to the Successful): Models how advantages (wealth, resources) allow some actors to better weather crises, while disadvantages accumulate for others, creating a feedback loop where inequality exacerbates the overall polycrisis https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1.
- Crisis Deferral (Policy Resistance): Explains how “quick fixes” to one crisis (e.g., using antibiotics or fossil fuels) create unintended side effects that trigger new crises elsewhere, effectively deferring the problem while making it worse https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1.
This approach uses Causal Loop Diagrams (CLDs) to visualize these interactions, helping policymakers identify “leverage points” where interventions can break negative cycles https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1.
2. The Cascade Institute Polycrisis Core Model
The Cascade Institute has developed a specific modeling tool called the Polycrisis Core Model. This is a quantitative systems mapping tool designed to explore plausible futures (e.g., for the year 2040).
- Methodology: It uses Cross-Impact Balance (CIB) analysis. This method identifies “consistent scenarios” by testing how different global stressors (climate, inequality, geopolitical tension) influence one another.
- Goal: It aims to move beyond linear risk assessment to find stable patterns the global system could settle into, whether positive or catastrophic. The model is open and intended to be modifiable by other research groups and communities https://cascadeinstitute.org/polycrisis-core-model/.
3. The “World Problematique” and Syndromes of Global Change
Historically, the concept of the polycrisis evolved from the “World Problematique” framework introduced by the Club of Rome in the 1970s (famous for The Limits to Growth).
- Syndromes of Global Change: This earlier framework identified recurring patterns of environmental and socio-economic interactions (e.g., “Shrinking Arable Land”) that lead to sustainability challenges. Modern polycrisis modeling often views these as precursors, updating them with more dynamic, non-linear interaction models https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1 https://www.sciencedirect.com/science/article/pii/S2405872624000790.
- FRIDA Model: A newer system dynamics model (FRIDA) is being developed to simulate coupled human-Earth systems, explicitly designed to handle the complexity of the polycrisis https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1.
4. Key Methodological Principles
Across these frameworks, three core principles distinguish polycrisis modeling from traditional risk analysis:
- Non-Linearity: Models must account for feedback loops where a small change in one system causes a disproportionate collapse in another https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1.
- Transboundary Causality: Crises do not respect political or sectoral boundaries; models must trace causal chains across climate, economy, and social systems simultaneously https://www.cambridge.org/core/journals/global-sustainability/article/polycrisis-patterns-applying-system-archetypes-to-crisis-interactions/95925B186BBA3A9675127480B103FCC1.
- Deep Uncertainty: Because these systems are highly complex, models focus less on predicting a single future and more on exploring a range of “consistent scenarios” to build resilience https://cascadeinstitute.org/polycrisis-core-model/.
Summary of Available Tools
If you are looking to apply these frameworks, the Cascade Institute offers a handbook on reading and drawing Causal Loop Diagrams, which is often the first step in building a polycrisis model https://cascadeinstitute.org/polycrisis-core-model/.
Starter Framework
the Polycrisis Patterns Framework (based on system archetypes) is currently the most prominent and academically supported conceptual framework for modeling how crises interact.
Developed by researchers at institutions like the Stockholm Resilience Centre and published in Global Sustainability (2025), this framework translates complex global dynamics into three recognizable “patterns” that explain why separate crises amplify one another:
- Converging Constraints: Describes how growth in one system (e.g., manufacturing) hits physical limits (e.g., climate) in another, causing them to reinforce each other negatively [1].
- Deepening Divides: Explains how inequality creates a feedback loop where the wealthy gain resilience while the vulnerable suffer greater losses, reducing global cooperation [1].
- Crisis Deferral: Illustrates how “quick fixes” (like using antibiotics or fossil fuels) treat symptoms but create new, larger crises elsewhere, effectively deferring the problem while making it worse [1].
While this is the leading conceptual framework, the Cascade Institute’s Polycrisis Core Model is the leading quantitative tool. It uses Cross-Impact Balance analysis to map stable and unstable futures for 2040, helping governments identify “positive pathways” to avoid catastrophic scenarios [3].
Starter List: Global Crises Affecting All Nations
While the severity varies by region, the following crises are structural and systemic, affecting every nation to some degree. These are the primary nodes in the “polycrisis” web:
| Crisis Category | Core Dynamic | Global Impact |
|---|---|---|
| Climate Change | Rising global temperatures and extreme weather events | Disrupts agriculture, water supplies, and infrastructure everywhere; drives migration and economic volatility [1]. |
| Biodiversity Loss | Rapid extinction of species and ecosystem collapse | Weakens natural systems that provide food, medicine, and climate regulation, making all nations more vulnerable [1]. |
| Resource Scarcity | Depletion of critical minerals, water, and arable land | Drives competition for resources, increases food prices globally, and fuels geopolitical tension [1]. |
| Economic Instability | High debt, inflation, and widening wealth gaps | Creates social unrest, reduces government capacity to respond to other crises, and increases poverty worldwide [1]. |
| Geopolitical Fragmentation | Erosion of international cooperation and rising nationalism | Prevents coordinated action on global threats (like pandemics or climate), leading to slower, less effective responses [1]. |
| Public Health Risks | Emerging pathogens and antimicrobial resistance | Pandemics and drug-resistant infections threaten all populations regardless of borders; antibiotic overuse creates long-term crises [1]. |
| Digital & Information Chaos | Spread of misinformation and AI-driven disinformation | Undermines trust in institutions, destabilizes elections, and hinders collective action on critical issues [6]. |
| Migration & Displacement | Forced movement due to climate, conflict, or poverty | Strains resources in receiving nations, creates social tension, and challenges global governance frameworks [1]. |
These crises are not isolated; they interact through the “Converging Constraints” and “Deepening Divides” patterns. For example, climate change (Crisis 1) reduces food production, which drives up prices and increases economic instability (Crisis 2), potentially leading to geopolitical conflict (Crisis 3) and mass migration (Crisis 4).
