Agrobiodiversity (chagra & rare crops)

Overview

Savimbo Agrobiodiversity is one of several payment layers Savimbo offers to smallholder farmers and Indigenous communities that steward tropical forest, mainly in the Colombian Amazon. It rewards preservation of rare and traditional crops, chagra polyculture systems, and Indigenous agricultural knowledge, and it supports organic certification so farmers can reduce pesticide use and earn higher prices. Payments are tied to maintaining diverse crop species, and Savimbo shares a portion of credit revenue directly with the grower who originated the credit. The program was still undergoing certification and refinement at the time of review.

01 · Roles

The 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. Hover to trace, click to inspect; revise edges (dashed) send work back.

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.
