About the session

Food systems worldwide face unprecedented challenges from climate change, population growth, economic inequalities, and ecological degradation.

These systems exhibit complex behaviours with emergent properties, non-linear dynamics, and intricate feedback loops that require novel analytical approaches.

This session invites contributions that apply complexity science frameworks to understand and transform food systems.

We welcome theoretical, methodological, and empirical work from diverse disciplines, including but not limited to:

• Agroecology
• Food economics
• Supply chain modelilng
• Social-ecological systems
• Policy analysis
• Network science applications
• Computational modeling
• Resilience assessment

Potential topics of interest include:

• Agent-based modeling of food system behaviours
• Network analysis of food supply chains
• Resilience thresholds in agricultural systems
• Complex adaptive systems approaches to food policy
• Emergent properties in local/global food networks
• Non-linear dynamics in food price volatility
• Adaptation pathways for climate-resilient food systems
• Social-ecological feedbacks in food systems
• Food system transitions and tipping points
• Participatory complex systems modeling with stakeholders.

Publication Opportunities

Selected papers may be invited for submission at Complexity (Wiley), Complex Systems (PLOS), and Journal of Computational Science (Elsevier).
