Post-colonialist Ecotourism
Community-designed, immersive travel on equal footing with Indigenous hosts: shared aims, shared economics, on their terms.

The issued hypercert is a batch of SEC credits recorded at once, comparable to a registry issuance batch. It carries weighted contributors, a work scope and a rights record, so any app in the ATProto Collective Funding Ecosystem can read it natively.
Overview
Savimbo post-colonialist ecotourism is a community payment layer that offers travel experiences hosted by Indigenous and local communities on shared and equal terms. The program frames tourism as educational and experiential, with community designed and immersive visits arranged on the communities' own terms and with limited availability. Revenue from these experiences flows to the host communities through Savimbo's collective payment system, reducing the number of intermediaries between buyers and the people doing conservation work. It is offered alongside Savimbo biodiversity, carbon, and agroforestry programs.

01 · Roles
Standard Registry
role · registry
Owns the policy, approves participants, anchors each issuance to its evidence.
Project Proponent
role · proponent
Registers the project and submits monitoring reports.
Validation & Verification Body
role · vvb
Independently validates the design and verifies monitored data.
02 · Policy graph
10 nodesThe workflow as an explicit directed graph. In Graph each column is one role, so you can see who acts at each step; every node names the org.broadlistening.policy.block.* def it resolves to plus its input and output record. Data flow switches to a lineage view that makes explicit what data each node needs and makes, with dependency arcs tracing every record back to the node that produced it, including where the Darwin Core occurrence + measurement records feed in.

03 · Generated lexicon records
The records this methodology compiles to, ready to write to a PDS. The first tabs are the new policy engine records; the ★ claim.activity tab and those after it are reused ATProto Collective Funding Ecosystem records (org.hypercerts.*): the issued hypercert batch, its rights, an example verification attachment and a retirement receipt. The ◈ dwc.occurrence and ◈ dwc.measurement tabs are the Darwin Core field evidence the monitoring node writes; see the section below.

05 · Field evidence (Darwin Core)
A ecotourism credit is only as credible as the field-evidence timeline behind it. The baseline and monitoring nodes above don't just file a document: they write a species-occurrence timeline with GainForest's Darwin Core lexicons (app.gainforest.dwc.*). The verification node then audits those records, and the compute node reads them to quantify the unit.
The evidence record chain
app.gainforest.dwc.dataset
Groups a batch of occurrence records uploaded together as one cohesive, referenceable unit.
app.gainforest.dwc.event
The sampling event: location, habitat, protocol, effort and conditions shared by many occurrences (star-schema).
app.gainforest.dwc.occurrence
One organism (or group) at a place and time, carrying species identity, abundance, coordinates, conservation status and evidence media.
app.gainforest.dwc.measurement
Typed facts about an occurrence: floraMeasurement (trees/plants/corals), faunaMeasurement (animals) or genericMeasurement (anything else).
app.gainforest.ac.deployment
A passive-acoustic / camera device placed for a period, giving the effort context behind machine-observation occurrences.
app.gainforest.ac.audio
Bioacoustic recording (AudioMoth, Song Meter…) linked to an occurrence as raw, replayable evidence.
app.gainforest.ac.multimedia
Image / video / spectrogram (camera trap, drone still, dive photo) linked to an occurrence as evidence.

How the evidence becomes a credit
Verified visitor-nights fund conservation; DWC occurrences evidence the wildlife the visits sustain on IPLC land.
