A day’s fishing nets €30, and records nothing
Out by three. Forty minutes to the grounds. BLUERA students sometimes join him.
Every meadow, and where it thins. Where boats anchor too. Forty years of it, none written down.
The knowledge goes home. The catch goes to a broker for €30 of profit after operating costs. The fish are disappearing, and Posidonia is only one factor. This is why stewardship has to pay before it can be asked for.

Seen, then forgotten.
Turning an informal network into a formal one
Extent mapping. Posidonia is present, and little else. ISPRA 2017, thinly ground-truthed, and past visual depth below about 30 metres. It cannot carry a baseline.
A local sovereign model, built with the science community. The digital twin of Posidonia on this coast: existing survey data integrated, predictions from open models (ESA and Copernicus), and the picture put directly into the community’s hands. Live today, open it.
How much, in what condition, where it is breaking up. This is the only kind of map that can carry a credit, and it exists almost nowhere, because survey capacity is the binding constraint. Compared for method rather than place: these are different sites.
Four screens, and the boat works as it always did
The pairing is the interface. The fisherman brings the boat and forty years; the student brings the phone.
Scientists here are short of coverage, not expertise
- Where to dive next. Broad, frequent, shallow coverage from the fleet shows a research team where the meadow is changing, so limited dive days go where it matters. The fleet extends their reach; it does not replace them.
- Provenance-grade records. Every point carries a vessel, a route, a timestamp and a named operator: the audit trail a verifier asks for, and what satellite extrapolation cannot produce. Side-scan sonar, temperature, GPS and photogrammetry.
- Continuous verification, not a periodic survey. The fleet that builds the baseline refreshes it permanently at marginal cost, so verification becomes a standing local function instead of a recurring shock to a project budget.
The same loop works over mangroves. TAHIRY HONKOThe community-led version is proven at scale in Madagascar: over 1,200 hectares under Plan Vivo, community-monitored, twenty-year credit revenue to the villages. It has never been built in the Mediterranean.

Data becomes understanding only where a person stands next to it.
Somebody has to run this. THE COORDINATORRoutes set, boats coordinated, returns reviewed, the public side kept alive. A paid local coordinator is the first line of the proof-of-concept budget rather than an overhead on it. Without one this is volunteer scheduling and it produces nothing anyone can cite.
Protection first. Then everything it unlocks.
Once protection holds, restoration becomes worth funding. For now, a sandbox.
Build a plan, see what returns. Simulate different investment plays across infrastructure and marketing, and compare what each buys.
Set the variables, run the clock. Simulate scenarios for the future of Cilento’s meadows: build the blue carbon economy, or price the cost of inaction.
