- Leading to Action & Transformation? How Researchers are Applying System Thinking to Overcome Food System Challenges
Abstract Systems approaches are becoming widely recognised for their potential to address the complexity of food systems’ challenges and lead needed transformations. However, there is limited attention on how systems thinking is being applied across food systems research, for what purposes, and with what impact. Based on four research questions, this paper presents the results of a systematic review of articles that describe and categorise the application of systems thinking approaches to food systems research for which a systems model – employing a graph-based representation - has been…

ABSTRACT This paper presents ChatXmile, a browser‐based method and web application (the ChatXmile system) that integrates large language models (LLMs) with deterministic, rule‐based software to streamline system dynamics modeling. In a closed‐loop workflow, an LLM generates or revises an XMILE model, which is then subjected to automated conformance and technical checks (schema and rule checks, units consistency, structural inspection, and executable trial runs). Diagnostics are fed back to guide targeted revisions. Once a model passes these checks, ChatXmile also supports generating…
- Earthly Models
Models of floods, disease, lakes, and fish don’t arrive ready-made – they’re patched together from code, data, software, theory, habits, and disagreement. Anja Klein follows that patchwork in action through fieldwork with two interdisciplinary research groups: a project in Accra tracking diarrhea and flood risk under climate change, and a Stockholm-based group building simulation models of social-ecological systems. How do materiality, difference, and complexity get handled in the daily work of modeling? What gets to be included and what is left out and why? Moving between ethnography and…
- When adaptation becomes maladaptation: drought-groundwater feedbacks and resilience in agricultural socio-ecological systems
Abstract This study investigates how increasing drought pressure, groundwater decline, and rapid land use/land cover (LULC) change reshape the resilience and feedback dynamics of an agricultural socio-ecological system. An integrated framework combining hydroclimatic, vegetation, water, soil moisture, groundwater, and LULC indicators was used to assess long-term changes and critical system transitions. Despite intensifying drought and persistent groundwater decline, vegetation greenness increased, indicating that agricultural production has been sustained beyond natural hydroclimatic limits…
- Orientations to navigate the complexity of freshwater resilience in social-ecological systems
Resilience is a widely applied and diversely interpreted concept in freshwater science with applications that span disciplines, analytical frameworks, scales of analysis, and system delineations. This diversity leads to an equally rich variety of resilience insights which are difficult to compare, aggregate, synthesize, and apply in decision-relevant contexts. Here, we seek to support greater critical and reflexive awareness of how freshwater resilience insights are generated by proposing three social-ecological orientations: 1) freshwater resilience as a shared physical and social reality;…
- Cyclic droughts, flooding and collective trauma: an environmental feedback loop to inform governance and socio-ecological resilience in Kenya’s rift valley
Climate change is recognised as a multidimensional crisis affecting ecological integrity, food systems, and human well-being. Attention has been given to biophysical and economic consequences of climate variability. Less emphasis has been placed on cumulative psychological and social impacts. Collective trauma is a critical but largely overlooked dimension of climate adaptation and conservation science. Using Kenya’s Rift Valley as an illustration, we suggest that recurrent droughts and floods have created a self-reinforcing socio-ecological feedback loop where environmental degradation,…
- Governance Near Criticality: Rethinking Intervention under Critical Transition Uncertainty
This paper develops a conceptual framework for political response near critical states. The point of departure is a limited but important implication of nonlinear dynamics: when a system approaches a critical transition, relatively small perturbations can sometimes produce changes that are disproportionate to their initial magnitude, while subsequent return may become difficult under hysteresis, path dependence, or self-reinforcing feedback. The political significance of this condition cannot be reduced to a problem of improved control. Near criticality, information about leverage can…
- Agent-based models in dietary behaviour: a scoping review
Agent-Based Modelling (ABM) simulates complex systems characterised by individual interactions and decision-making, making it valuable for studying dietary behaviour. This scoping review evaluated dietary-based ABM studies. Diet-related ABM studies published in peer-reviewed journals were eligible. Medline, Web of Science, and Scopus databases were searched in May 2024 (PROSPERO: CRD42023457091). A narrative synthesis of the included studies was then conducted. Risk of bias was assessed using bespoke ABM quality criteria. Across 30 eligible studies, 15 tested interventions, some testing…
- Disrupting antimicrobial resistance in food systems from a One Health perspective: a complex systems analysis in Canada, Senegal and the Netherlands
BACKGROUND: Food systems are a key contributor to antimicrobial resistance (AMR). Given the multi-sectoral nature of AMR, a One Health perspective has been advocated. Recent research situates AMR as an emerging property of a complex system, a perspective which can help identify root drivers of AMR and theorise the impacts of proposed solutions. This study aims to combine systems modelling and a One Health perspective to identify system-level dynamics and priority actions for addressing AMR in food systems. METHODS: We used group model building, a participatory approach to systems modelling,…

Full transcript
Researchers frequently model the dynamics of food networks without tracking whether those diagrams ever alter conditions on the ground. Addressing that gap between systemic analysis and operational action is our focus today on ComplexityPod, where we explore complex systems research. First, the papers.
A review of thirty-five case studies applying graph-based modeling and systems thinking to food systems reveals a clear boundary: the work almost exclusively diagnoses problems.
The numbers show that boundary directly. Out of thirty-five projects, two tracked whether anyone implemented their interventions, and only one recorded evidence of a concrete action occurring.
It stops at conceptual mapping. And even when models simulate specific policies—like the thirty agent-based studies looking at dietary choice—the interventions carry unintended consequences.
Specifically on pricing interventions. Fifteen of those studies simulated price changes. While price shifts lowered the consumption of targeted items, they consistently widened socioeconomic disparities.
And those agent-based models shared another pattern: their agent decision rules rarely drew on formal behavioral theories, and stakeholders were absent from the model formulation.
Which is the opposite approach of the antimicrobial resistance workshops run across Canada, Senegal, and the Netherlands. Thirty-nine stakeholders built causal loop diagrams together to trace systemic traps.
They identified standard systems archetypes—like common-pool resource exploitation driving a continuous baseline reliance on antibiotics in animal husbandry.
Because the mapping involved multiple sectors, the resulting leverage points were not confined to veterinary clinics. They targeted the structural design of livestock housing, consumer education, and coordinated cross-sector regulations.
Of course, building those models with stakeholders demands technical time. That is the barrier ChatXmile attempts to address by linking large language models with deterministic checking tools.
The language model proposes the simulation equations in standard XMILE format, but it cannot run uninspected code. A deterministic engine parses the file for schema rules, dimensional and unit consistency, and network topology, then executes test runs.
If a unit does not balance, or a feedback loop breaks, the diagnostic error returns straight to the model to rewrite the code. Once the script clears validation, it exports an interactive simulator for parameter sweeps and extreme condition runs.
That process automates technical compliance, but it does not resolve the human choices that shape a model. Anja Klein's field observations in Accra and Stockholm tracked exactly that human layer.
Klein watched teams assemble flood and disease models line by line. What ends up in the simulation is not purely a reflection of physical dynamics; it is determined by existing data availability, coding habits, and professional negotiations over which social variables to drop.
And dropping variables can mask long-term risks, as shown by the multi-decadal study on irrigated agriculture. Between 2004 and 2008, farmers sustained surface crop greenness during drought by pumping groundwater.
On the surface, the adaptation appeared functional. Below ground, the aquifer was depleting to structural limits. Short-term stabilization generated a delayed, destabilizing feedback loop.
To capture those cross-scale traps across different geographies, researchers working on freshwater governance synthesized three social-ecological orientations. They tested them across the Central Valley, the Sahel, the Mekong, and the Amazon Basin.
Their framework establishes three baseline requirements: treating physical and social dynamics as a unified system, incorporating diverse knowledge traditions, and treating resilience as an emergent behavior of open systems rather than a fixed state.
In Kenya's Rift Valley, that combination of social and ecological dynamics becomes intensely local. Researchers documented how alternating floods and droughts create collective psychological trauma in communities.
That trauma compresses time horizons. People adopt short-term survival strategies that strip vegetation and accelerate soil erosion, which amplifies the severity of the next flood.
The response cannot just be physical infrastructure. The study demonstrates that institutional adaptation has to integrate psychosocial support alongside local ecological practices to disrupt the feedback loop.
Once a system approaches that level of threshold behavior, conventional control mechanisms often backfire. A conceptual study on political decision-making examined systems exhibiting hysteresis and accelerating feedbacks.
Pushing a direct, heavy intervention near a tipping point can trigger an irreversible shift in system state and eliminate future policy choices.
The authors argue for an alternative repertoire: system buffering, redirection, and deliberate restraint, drawing parallels to non-coercive principles from Daoist philosophy.
Several other developments appeared this cycle. In engineering curricula, researchers are integrating a biopsychosocial and cultural model to teach systems concepts.
Coastal research yielded a Six-Pillar Socio-Ecological Infrastructure Framework for mangrove systems, while another study evaluated the Baree system as a multifunctional production landscape.
In financial systems, K-shell decomposition mapped systemic risk networks in China, and a long-term study evaluated contagion across ten Asian foreign exchange markets from 1994 to 2025.
Finally, researchers modeled electric motorcycle battery waste dynamics in Indonesia using causal loops, and mapped the interlocking feedbacks sustaining healthcare inequities across Scotland.
More research summaries on systems thinking and complex dynamics arrive next week. From ComplexityPod, thanks for listening.
