Article “Using agent-based modelling to simulate social-ecological systems across scales”

New

Agent-based modelling (ABM) simulates Social-Ecological-Systems (SESs) based on the decision-making and actions of individual actors or actor groups, their interactions with each other, and with ecosystems.

Many ABM studies have focused at the micro-scale of villages, rural landscapes, towns or cities. When considering a geographical, spatially-explicit domain, current ABM architecture is generally not easily transferable to a larger regional or global context, nor does it acknowledge SESs interactions across scales sufficiently.

There is a need for ABM to cross the gap between micro-scale actors and larger-scale environmental, infrastructural and political systems in a way that allows realistic spatial and temporal phenomena to emerge; this is vital for agent-based models to be useful for policy analysis in an era when global crises can be triggered by small numbers of micro-scale actors. This thought-piece suggests conceptual avenues for implementing ABM to simulate SESs across scales, and for using big data from social surveys, remote sensing or other sources for this purpose.
