The areas of biodiversity and nature this platform takes on.
Biodiversity Nexus studies the living fabric of the planet and the risks its loss creates for people and economies: ecosystem integrity, species and genetic diversity, forests, wetlands, coasts and oceans, restoration, ecosystem services and the rights that govern nature data. Its pages set out the science, the data, the methods and the decisions for each part of that system, with every value labelled by its evidence and every limit stated.
Ecosystem integrity
Condition, thresholds and collapse risk across terrestrial, freshwater and marine ecosystems, measured against a stated reference.
Species and genetic diversity
Populations, extinction risk and genetic variation, with the gaps in data across groups and regions made explicit.
Forests and landscapes
Forest loss, degradation and fragmentation, and the commodity and finance links that drive them.
Wetlands and freshwater
Rivers, lakes, floodplains and peatlands, their connectivity, and the resilience they give to watersheds.
Coasts and oceans
Coral reefs, mangroves, seagrass, fish stocks and the open ocean under fishing, warming and acidification.
Restoration and nature-based solutions
Monitoring and evaluating restoration and ecosystem-based measures against credible counterfactuals.
Ecosystem services and dependencies
Pollination, flood buffering, water and livelihoods, and how their loss propagates into food systems and finance.
Nature data and rights
Licences, consent, sensitive locations and benefit sharing in the collection and use of ecological data.

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.

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.
Its community
Ecologists; conservation scientists; land managers; Indigenous/community stewards; biodiversity data experts.
Its methods
Habitat observations; ecological indicators; remote sensing; impact uncertainties.
Its outputs
Biodiversity evidence notes; ecosystem maps; restoration evaluation guides.

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.
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.

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.
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.
Condition and change
Habitat surveys, species monitoring and satellite records combined into indicators of ecosystem condition, with the gaps in coverage stated.
Dependencies and risk
Analysis of which communities, sectors and infrastructure depend on which ecosystem functions, and how loss would propagate.
What works
Restoration and conservation outcomes compared against counterfactuals, so that effort follows evidence rather than intention.
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.
- Climate and Nature Governance at GRFInstitutionGRFWhat it addsConvening and dialogue on nature policy and law, including source and consent limits.
- Climate and Nature Financial Risk at GRAInstitutionGRAWhat it addsShared industry understanding of how nature dependencies reach balance sheets.
- Asset Management NexusInstitutionGRAWhat it addsHow investors frame nature-related exposure as sector analysis, not advice.
- Oceans and CoastsInstitutionGCRIWhat it addsSteward of ocean and coastal science, shared with the marine topic here.
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.
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.

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.

GCRI studies a field as science, GRF governs it and GRA builds shared financial understanding of it. Biodiversity Nexus links to its counterparts so that work on one side is visible on the others.
