Model Biodiversity Nexus as a system. Run the cascade.

Assembled from the Nexus Standards area profile Biodiversity and nature risk standards: the hazards it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

05Overview

What Biodiversity Nexus does.

Biodiversity loss is the decline in the variety of life at genetic, species and ecosystem level, driven mainly by land and sea use change, direct exploitation, climate change, pollution and invasive species, in IPBES assessments. Biodiversity Nexus covers ecosystem integrity, species and genetic diversity, forests, wetlands, coasts and oceans, restoration, ecosystem services and the rights that govern nature data.

07GCRI’s mandate in biodiversity

What Biodiversity Nexus does, and what stays with nature authorities and rights-holders.

Biodiversity Nexus studies the state of nature, what it provides and how its loss travels into water, food, health and economies, and helps countries build the evidence to act under the Kunming-Montreal Global Biodiversity Framework. It designates no protected area, issues no credits, verifies no offset, approves no project and holds no rights over genetic resources or traditional knowledge; environment ministries, CBD national focal points, Indigenous peoples and local communities hold those roles.

Maps and indicators on these pages are illustrative unless a page says otherwise, never a finding about a place. Readiness is not authority. National biodiversity strategies, data and decisions stay national, and protected knowledge never enters public outputs or model training.

08Methods and evidence

How Biodiversity Nexus is modelled, measured and tested.

The model, its assumptions, its data and its uncertainty, in the form a scientist or engineer would check. Structures follow published methods. The values drawn are illustrative, not findings.

10Contribute

What ecologists, field teams and rights-holders can add.

  • Observations: species and ecosystem surveys, shared through GBIF or under terms.
  • Monitoring: long-term records from restoration and protected sites.
  • Knowledge: local and Indigenous knowledge, only with free, prior and informed consent.
  • Corrections: through corrections.
11The problem

Living systems hold up more than they appear to.

Ecosystems are not a backdrop to human activity; they are working systems. Soils cycle nutrients and hold water, wetlands store floodwater and filter it, forests regulate local climate and stabilise slopes, reefs and mangroves absorb wave energy, and pollinators set the yield of many crops. Each of these functions rests on biodiversity: the variety of genes, species and ecosystems, and the interactions among them that keep processes running when conditions change.

The main drivers of loss are well established in ecological science: change in land and sea use, direct exploitation of species, climate change, pollution and invasive species. They rarely act alone. A fragmented forest is drier and more exposed to fire; a polluted river loses the species that would otherwise process the pollution; a warming sea weakens reefs already stressed by fishing. Because ecosystems respond to combined pressure in non-linear ways, decline can look gradual until a threshold is crossed and a system shifts into a different, often less productive state that is slow or costly to reverse.

When that happens the consequences travel. Lost flood buffering raises losses downstream, pollinator decline affects harvests and prices, fishery collapse reaches coastal livelihoods and food security, and degraded watersheds raise the cost of water treatment. These dependencies are often invisible in accounts and plans until they fail. The field exists to make them visible early enough for the people responsible to act.

12What the platform does

Evidence on nature, built to be used and checked.

Biodiversity Nexus produces biodiversity evidence notes, ecosystem maps and restoration evaluation guides. Its methods combine habitat observations, ecological indicators, remote sensing and explicit treatment of impact uncertainty. Its work is for researchers who need comparable evidence, for land and sea managers who need to know what is working, and for the public bodies and communities who decide how land and water are used.

Observe

Condition and change

Habitat surveys, species monitoring and satellite records combined into indicators of ecosystem condition, with the gaps in coverage stated.

Connect

Dependencies and risk

Analysis of which communities, sectors and infrastructure depend on which ecosystem functions, and how loss would propagate.

Evaluate

What works

Restoration and conservation outcomes compared against counterfactuals, so that effort follows evidence rather than intention.

13Foundations and counterparts

Grounded in named methods, connected across three institutions.

Biodiversity Nexus stewards ecology and biodiversity science in the STEM Commons and applies Earth observation and remote sensing, spatial statistics, geospatial information systems, complex systems modelling, causal inference, hydrology and ocean and coastal science. The full set is on the STEM foundation page. The same field is governed at the Global Risks Forum (GRF) and examined for financial exposure at GRA, so evidence produced here can inform both without either taking it over.

14Grounding

Built on named science, technology, engineering and mathematics.

Every claim on Biodiversity Nexus rests on methods with a canonical page in the STEM Commons, so readers can see what a finding depends on and where its limits lie.

15Cycle

How work moves in this field.

A question becomes evidence, a governed build, an organised community, a controlled test, a reviewed publication and, finally, a decision taken by the competent authority under its own rules.

  1. Question Universe National, regional or institutional priority. Question in Biodiversity Nexus
  2. Evidence Foundry STEM foundation of the platform. Evidence in Biodiversity Nexus
  3. Build Foundry Foundry. Build in Biodiversity Nexus
  4. Organise Universe Nexus ecosystem. Organise in Biodiversity Nexus
  5. Test Universe Universe (independent site). Test in Biodiversity Nexus
  6. Publish Reports Reports. Publish in Biodiversity Nexus
  7. Decide Competent authority Competent authorities and institutions, through NXS-RLS (participants, agreements and handoffs). Decide in Biodiversity Nexus
  8. Renew Universe Corrections and the next annual agenda. Renew in Biodiversity Nexus

Each step of the cycle in the pillar it runs in; the decision stays with the competent authority, outside the programme.

16Six pillars

How this works across the six pillars.

Biodiversity Nexus works through six pillars of one annual programme, led by the Nexus Consortium, with GCRI, GRF and GRA each contributing in its role: explore, experiment and prototype in Labs, build, simulate and prepare in Foundry, convene and test in Universe, codify, correct and apply in Nexus Standards, publish in every format in Reports, teach in the open in Risk Academy.

What the work is read against.

The platform does not set standards. It reads its evidence against the frameworks that competent bodies have adopted, so a finding can be placed where a decision-maker already works.

22Questions

Questions and answers.

Who publishes Biodiversity Nexus?
The Global Centre for Risk and Innovation (GCRI) publishes Biodiversity Nexus and is responsible for what it publishes. GCRI is a research, development and policy institution. It is not a regulator, and it does not certify, license or approve; its findings carry their methods and uncertainty.
Is Biodiversity Nexus active?
Biodiversity Nexus is an established platform of The Global Centre for Risk and Innovation. Information and enquiries are open today. 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.
How can I contribute?
Start with the participation paths or write to the contact form. An enquiry receives a reference; it does not create membership, a role or an assignment.
Where are findings published?
Reviewed outputs appear on the publications page, and contributions to the Reports series are listed on Publish in Reports.
Which values on this platform are real?
Indicator names, units, sources, methods and frameworks are real. Levels in figures and canvases are examples in a design. A programme replaces them with labelled evidence it owns.
How do I report an error?
Use corrections and concerns, or write to the integrity concern form. A correction is recorded as a new version, never a silent edit.
What does Biodiversity Nexus mean by nature-related risk?
The risk that loss or degradation of ecosystems harms people, infrastructure or economic activity that depends on them, for example through reduced flood buffering, lower crop pollination or the collapse of a fishery. It includes both the physical consequences of decline and the way they travel through supply chains, public budgets and livelihoods.
Who is the platform for?
Ecologists, conservation scientists, land and sea managers, Indigenous and community stewards and biodiversity data specialists, together with the public bodies and organisations that use their evidence. Participation is by competence and interest; an enquiry does not create membership or a role.
