From the article "The Energy System Sciences (ESS) see all systems as “flow networks” or structures that arise from the circulation of resources, information, nutrients, etc. Thinking through the lens of flow, systemic health can be seen as being based on things like: investment and re-investment of key and diverse resources, healthy outflows (not polluting or poisoning the ecosystem), the velocity and spread of resources in the system, cross-scale circulation, etc. The nature and quality of these flows determines how systems are able to adapt and evolve in healthy and health-promoting ways.
