Biodiversity Gains in Agrarian Landscapes

Overview

The Fundacion Global Nature methodology quantifies biodiversity gains or losses in agrarian ecosystems that result from specific land management practices. It measures change across a given area using a preselected set of biodiversity indicators, and it has no geographic restriction provided the intervention site is an agrarian ecosystem. The approach produces biodiversity units that companies can use to project, quantify, and report improvements in biodiversity on farmland in a verifiable and comparable way. It is aimed at corporate reporting needs and custodianship of farming landscapes.

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.
