Agrobiodiversity Enhancement

Overview

EA02 Agrobiodiversity enhancement is an eligible project category defined in the Cercarbono Biodiversity Certification Programme (CBCP) Protocol. It covers actions that increase agricultural biodiversity, including conservation of crops, livestock breeds, and pollinators along with their associated ecosystems, and practices such as regenerative agriculture, with priority given to threatened or native species. Projects are quantified through an approved biodiversity methodology under the programme and issue biodiversity credits that are independently verified. The category sits alongside other CBCP interventions and uses indicator based monitoring of biodiversity outcomes.

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.
