The Global Centre for Risk and Innovation (GCRI)
The Nexus cycle in Biodiversity Nexus: question, evidence, build, organize, test, publish, decide and renew, with the page and owner of each step.
The Nexus cycle in Biodiversity Nexus is the eight-step path by which a question in the biodiversity and nature field becomes evidence, a Foundry build, an organized community, a controlled test, a publication and a decision taken by the competent authority. Here the evidence step rests on ecology and biodiversity science as well as Earth observation and remote sensing, and findings feed Global Sector Risk and Resilience.

For how work moves in this field, in GCRI's spatial-intelligence reading, the map opens on land cover, vegetation, marine heat and true-colour imagery with true colour from NASA GIBS, framed on the Amazon Basin; every other NASA layer, live feed and forecast waits in the layer list.

Layers and dates
A Biodiversity Nexus cycle typically begins with a planning or accounting question, gathers occurrence, land-cover and condition data, builds ecosystem service models, tests them in a portfolio exercise and leaves the decision with planning authorities.
| Step | Owner |
|---|---|
| Question | National, regional or institutional priority |
| Evidence | STEM foundation of the platform |
| Build | Nexus Foundry |
| Organize | Nexus Ecosystem: community, chapters, councils, national cells |
| Test | Nexus Universe (independent site) |
| Publish | Nexus Reports |
| Decide | Competent authorities and institutions, through Nexus Rails |
| Renew | Corrections and the next annual agenda |
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Nexus cycle | The eight-step loop by which work moves in every Nexus field: question, evidence, build, organize, test, publish, decide and renew, each step with a named owner. |
| Competent authority | The body that a law or regulation designates to exercise a given power or duty, such as a supervisor, a civil protection agency or a ministry; only it can take the decisions the law assigns to it. |
| Peer review | Evaluation of a work by independent experts in the field before publication. |
| Kunming-Montreal Global Biodiversity Framework | The framework adopted under the CBD with goals for 2050 and targets for 2030 to halt and reverse biodiversity loss. |
The bodies and documents this page is read against. Status and editions change; each link goes to the issuing body.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
