Research Programme

Articulating complexity.

An interdisciplinary research programme using artificial intelligence to model the complex adaptive systems behind species conservation, biodiversity governance and societal resilience.

Articulating Complexity
The problem

Policies fail because complexity is ignored.

Across domains (biodiversity, climate, public health, national security) there is no shortage of beliefs about what ought to work. Yet policies routinely produce outcomes that diverge from their stated objectives, and the regularity with which this happens suggests that the failures are not incidental but structural.

The reason is that these are not technical problems. They are complex adaptive systems: systems whose components interact, learn and adjust their behaviour in response to one another. Social-ecological systems are a prominent instance, in which human agents with beliefs, strategies and competing interests are inseparable from the systems they govern. Anticipating how a policy will fare requires modelling how strategic actors will respond to it, including their capacity to deceive, negotiate, betray promises and revise their plans in light of new information.

Articulating Complexity is built on the premise that a new generation of tools can articulate this complexity, anticipate failure, and help design more resilient interventions.


Why now

New tools for an old problem.

Until very recently, no method existed to model the strategic, adaptive behaviour of real-world actors at scale. That has changed. The state of the art in large language models, multi-agent systems and computational capacity has moved dramatically over the past two years.

LLMs can now convincingly simulate institutional decision-making, replicate cross-cultural personality differences, sustain strategic reasoning across long interactions, and impersonate the rhetorical patterns of public figures. The window in which these capabilities can be turned into rigorous, transparent scientific instruments, rather than opaque commercial products, is narrow. This programme is an attempt to seize it.

The approach

Three methodological pillars tie the programme together.

The methodology is applicable across many issues. Whether the question is conservation, environmental diplomacy or societal resilience, the underlying machinery is the same.

Generative agent-based modelling

Traditional agent-based models govern agent behaviour with preset rules or numerical thresholds. We model agents instead as specific instances of large language models, tasked to impersonate stakeholders with their values, biases and rhetorical patterns. Each agent is a nested structure of sub-models designed to sustain coherent behaviour over long interactions.

Wargaming & serious games

These AI agents are embedded in structured serious games that simulate real-world strategic encounters: policy negotiations, crisis response, adversarial confrontation. With LLMs as players, what was once a single-replication exercise becomes a Monte Carlo experiment of many runs, opening up the distribution of plausible outcomes.

Pre-mortems

Rather than waiting for a policy to fail and asking why, we work backwards from simulated failure. A pre-mortem assumes the intervention has already collapsed and analyzes the AI-driven simulations to reconstruct the causal chain, identifying the decisions and adaptive responses that brought it down. The result is a map of vulnerability that exists before the policy is ever enacted.

The Projects

Several concurrent projects.

Each project applies the programme's shared methodological core to a different domain, using generative agent-based models and serious games to explore how policies interact with the strategic behaviour of real-world actors.

01
Conservation foresight

Can we foresee the outcomes of nature conservation policies?

The question we aim to answer is deceptively simple: can we tell, before a policy is enacted, whether it will work? For decades, conservation science has tried to learn from past outcomes, building "evidence banks" of what has worked in similar contexts. This project takes a different route. It develops simulations that ask "will it work?" for the specific policy and the specific political environment in which it will be implemented.

We build AI-driven serious games in which the relevant stakeholders (ministries, agencies, the European Commission, interest groups, the public) are impersonated by large language models. Thousands of iterations yield a distribution of possible futures, allowing failure modes to be identified ahead of time.

Environmental diplomacy

NatureDiplomacyAI: AI-generated environmental policies for sustainability

If human societies struggle to design environmental policies that deliver, could AI help? This project goes a step further than foresight: it asks whether artificial intelligence can co-design policies, exploring the high-dimensional space of possible policy instruments to identify configurations that are not just ambitious but politically and ecologically robust.

The method couples generative agent-based negotiations with automated search over the space of possible interventions. Agents impersonating real-world stakeholders negotiate; a learning loop iterates on the policy text, searching for designs that emerge intact from the political process.

Resilience & security

Generative wargaming of socio-ecological warfare

How could an open society be destabilised through vulnerabilities in its ecological and social fabric, without a shot being fired? This project examines an emerging category of non-conventional threat in which adversaries exploit or engineer disruptions in socio-ecological systems to generate political, social and economic instability.

Using AI-driven adversarial wargames, the project stress-tests societal resilience and conducts structured pre-mortems: working backwards from simulated failure to identify the points at which intervention is still possible.

People & opportunities

An ad-hoc team for an unusual question.

Articulating Complexity is a young programme assembling a small, interdisciplinary team at the intersection of artificial intelligence, complex systems, and the policy governance.

Guillaume Chapron

Principal investigator
Researcher (Docent)
SLU

Chapron leads the Articulating Complexity programme. He is a Researcher (Docent) in the Department of Ecology at the Swedish University of Agricultural Sciences (SLU). His work cuts across quantitative ecology, conservation biology, environmental law, and politics: a deliberately heterodox background built around questions of how societies govern, or fail to govern, the natural world.

He has published in Science, Nature, Nature Ecology & Evolution, PNAS and PLoS Biology. His earlier methodological work spans agent-based modelling, hierarchical Bayesian modelling and empirical law. He holds doctoral and master's degrees in ecology (Université Pierre & Marie Curie / ENS), a Master of Arts in international relations and contemporary war (King's College London), a graduate diploma in political science (University of London) and a Diploma of Veterinary Medicine (ENV Alfort).

If the programme resonates, we would like to hear from you.

Two positions are opening shortly. Both are based at SLU (Grimsö or Uppsala), with a possibility to be partly based at another Swedish institution with core expertise in the respective field.
