A metabolic study maps how materials and money move through a bioregion: which needs are met from within, which are imported, where money leaks out of the region with each purchase, and where circular loops could close.
Extended definition
Benjamin Life attributes the term to Samantha Power and Tyler Wakefield, and reports that the BioFi Project is developing the capacity at bioregional scale. In Life’s account, a metabolic study is one of two instruments behind the plan a Bioregional Development Organization holds. Evaluated for a city or county, it shows what the place loses to absentee ownership. Extended to a bioregional frame, it also shows circular-economy opportunities and the ecological thresholds the region has already crossed.
The study is dynamic. As a bioregion regenerates and more of its flows circulate internally, its carrying capacity changes, so the plan built on the study is redrawn as the economy it guides comes into being.
In the founding suite, a metabolic study is an optional input to the Place Mandate Template: it gives the Twenty-Year Value Ledger evidence for the value retained in the place, in the terms of retention economics.
Contrast with carrying-capacity analysis
Carrying-capacity analysis measures stocks against thresholds. Life draws it from the thresholds-and-allocations methodology of Bill Baue and colleagues at r3.0, which makes Kate Raworth’s doughnut computable for a territory. A metabolic study measures flows. In Life’s words: “Carrying-capacity analysis asks how much a watershed can bear. Metabolic analysis asks how value and materials actually move through it.” Carrying capacity sets the boundary condition; the metabolic study sets the goals for circulation within it.
