Concept
Socio-ecological system
Résumé
A social-ecological system consists of 'a bio-geo-physical' unit and its associated social actors and institutions. Social-ecological systems are complex and adaptive and delimited by spatial or functional boundaries surrounding particular ecosystems and their context problems.
A social-ecological system (SES) can be defined as:(p. 163)
A coherent system of biophysical and social factors that regularly interact in a resilient, sustained manner;
A system that is defined at several spatial, temporal, and organisational scales, which may be hierarchically linked;
A set of critical resources (natural, socio-economic, and cultural) whose flow and use is regulated by a combination of ecological and social systems; and
A perpetually dynamic, complex system with continuous adaptation.
Scholars have used the concept of social-ecological systems to emphasise humans as part of nature and to stress that the delineation between social systems and ecological systems is artificial and arbitrary. While resilience has somewhat different meaning in social and ecological context, the SES approach holds that social and ecological systems are linked through feedback mechanisms, and that both display resilience and complexity.
Social-ecological systems are based on the concept that humans are a part of — not separate from — nature. This concept, which holds that the delineation between social systems and natural systems is arbitrary and artificial, was first put forth by Berkes and Folke, and its theory was further developed by Berkes et al. More recent research into social-ecological system theory has pointed to social-ecological keystones as critical to the structure and function of these systems, and to biocultural diversity as essential to the resilience of these systems.
Through to the final decades of the twentieth century, the point of contact between social sciences and natural sciences was very limited in dealing with social-ecological systems.
