How does cultural coexistence theory complement existing theoretical frameworks in the world of sustainability science, specifically Elinor Ostrom's Social Ecological Systems (SES) Framework? A true science of sustainability must be able to explain periods of stability in complex human-natural systems; what CCT aims to do is just that: explain how competing groups of people in a shared resource setting come to coexist stably over time, as opposed to a scenario where one or more groups is pushed out because of some disadvantage.
