Social-Ecological System

A social-ecological system is a coupled, co-evolving system in which human societies and natural ecosystems interact through feedback loops that produce emergent dynamics neither social nor ecological alone. The concept rejects the separation of nature and society, treating resource users, governance institutions, and biophysical processes as components of a single complex adaptive system. The study of social-ecological systems draws on resilience theory, adaptive management, and panarchy to understand how such coupled systems persist, transform, or collapse under stress.

The framework has been applied to fisheries, forestry, water management, and urban systems. A key insight is that the resilience of the ecological subsystem and the adaptivity of the social subsystem are interdependent: rigid institutions can destroy flexible ecosystems, and collapsing ecosystems can destabilize even the most democratic institutions. Understanding these couplings requires methods that bridge the natural and social sciences, from agent-based modeling to participatory scenario planning.
