Natural Resource Managment (NRM) is a Complex Adaptive System (CAS) requiring Adaptive Management to be sustainable. The NRSUM model (above) is adapted from the NECSI-CAS model, which incorporates all ecosystem inputs, (energy, matter, information), regulation, adaptation, feedback loops and so on. At its core, however, is a HIERARCHY. A hierarchical structure is essential in NRM as it dovetails with both the organizational structures of demand as well as the regulatory mechanisms of supply. The NRSUM model is based upon the premise that sustainability requires balance between the demands of human activities (from the top-down), and the resources which ecosystems are able to provide (from the bottom-up).

All systems self-organize into a hierarchy. Organizations are simply a refinement of this natural process.

Ecosystem sustainability is dependent upon maximum biodiversity (i.e.: balance between the top-down and bottom-up regulatory mechanisms of the tropic pyramid). Either overexploitation by top predators or disruption of subsoil organisms will decrease biodiversity (species richness, distribution and diversity) at every level.

The NRSUM model derives from and enables verticle balance in natural resource analysis and use.
