The Nexus Standards, and where they are taught

Every area rests on the same few commitments: one identifier that identifies and never certifies, a public process that decides with written reasons, open licences, conformance shown from evidence, and closed standards named but never reproduced. This subsite holds those commitments and the machinery that keeps them.

The Foundations and Governance subsite on nexustandards.com, with 10 areas, among them Constitution and principles, The UNI and the artifact catalog, How a standard is made, Governance and liaison, Licensing and intellectual property, Conformance programme.

Climate, atmosphere, oceans, land and biodiversity are one coupled system: heat, water and carbon move between them, and a shift in one changes the hazard and exposure records of all the others. This subsite holds the observation, projection, disclosure and alignment standards that let those records be read together with their provenance intact.

The Climate and Earth Systems subsite on nexustandards.com, with 10 areas, among them Climate risk standards, Atmosphere and air quality risk standards, Oceans and coasts risk standards, Land and soil risk standards, Biodiversity and nature risk standards, Environmental degradation hazard standards.

Water allocation, crop production and food access fail together: a drought shows first in a basin, then in a harvest, then in a market price and a nutrition record. This subsite crosswalks the hydrological, agricultural and food-security instruments so that one shock can be traced along that whole chain.

The Water and Food Systems subsite on nexustandards.com, with 6 areas, among them Water risk standards, Food and agriculture risk standards, Agriculture and land use, Water utilities and basins, Food security and nutrition risk, FAO and food security.

Power, fuel, telecommunications, water and transport are interdependent networks: an outage propagates through them faster than any one operator can see. This subsite relates the asset, reliability, continuity and critical-entity standards that make those dependencies explicit and recordable.

The Energy and Critical Infrastructure subsite on nexustandards.com, with 5 areas, among them Energy risk standards, Energy utilities and grids, Critical infrastructure and critical entities, Technological and industrial hazard standards, Business continuity and resilience.

Human, animal and environmental health share pathogens, data systems and surge capacity, so an outbreak is also a logistics, finance and information event. This subsite relates surveillance, health-security and emergency standards to the identifiers and evidence records the rest of the ecosystem reads; on biosecurity it covers capacity and oversight only.

The Health and Biosecurity subsite on nexustandards.com, with 6 areas, among them Health risk standards, Biological hazard standards, Health systems, Health security and One Health, International Health Regulations alignment, WHO and health emergencies.

Cities concentrate exposure: people, buildings and networks share the same streets, codes and service footprints, and urban growth decides tomorrow's losses today. This subsite relates urban risk, construction, real-estate and urban-agenda instruments so that a building, a district and a city plan can carry one consistent record.

The Cities and the Built Environment subsite on nexustandards.com, with 5 areas, among them Cities and urban systems risk standards, Cities and the built environment, Construction and real estate, New Urban Agenda alignment, UN-Habitat and urban areas.

Hazards rarely arrive alone: an earthquake triggers landslides, a cyclone a flood, a heatwave a wildfire and a power failure. This subsite holds the hazard-family standards and the disaster risk reduction frameworks that describe events, losses and cascades in comparable records, with CAP 1.2 as its worked package.

The Hazards and Disaster Risk Reduction subsite on nexustandards.com, with 11 areas, among them Geophysical hazard standards, Hydrometeorological hazard standards, Chemical hazard standards, Wildfire and vegetation fire standards, Compound and cascading hazard standards, Space weather, spectrum and timing risk standards.

A warning helps only if it reaches people with time to act and if the action it triggers was agreed in advance. This subsite relates alerting protocols, hydrometeorological services and anticipatory-action triggers so that a forecast, a message and a release of funds can be traced to one another.

The Early Warning and Anticipatory Action subsite on nexustandards.com, with 3 areas, among them Early warning and anticipatory action, Alerting and messaging, WMO and hydrometeorological services.

Risk becomes financial when it is priced, insured, lent against or disclosed, and it becomes systemic when those positions move together. This subsite relates prudential, insurance, disclosure, payments and risk-finance standards to the hazard and exposure records they depend on; it never gives investment advice.

The Finance, Insurance and the Economy subsite on nexustandards.com, with 15 areas, among them Financial and economic risk standards, Finance, insurance and capital markets, Banking, Insurance and reinsurance, Asset owners and asset management, Development finance institutions.

Production and trade run on long chains of suppliers, carriers and chokepoints; a disruption at one node reaches firms that never knew it existed. This subsite relates the sector, logistics, continuity and operational-risk standards that let firms record and share those dependencies.

The Industry, Trade and Supply Chains subsite on nexustandards.com, with 7 areas, among them Industry and manufacturing, Transport, logistics and supply chains, Mining and extractives, Tourism and hospitality, Small and medium-sized enterprises, Supply chain and trade risk.

Digital systems, cyber threats and AI models now sit inside the records and decisions of every other system. This subsite relates cyber resilience, AI governance, telecommunications and model documentation standards so that a model, a dataset or an incident can be identified, described and verified.

The Digital, Cyber and AI subsite on nexustandards.com, with 9 areas, among them Cyber and digital risk standards, AI and autonomous systems risk standards, Frontier technology risk standards, Digital, telecom and platforms, Cyber resilience and digital operational resilience, AI governance frameworks alignment.

Institutions, conflict, information integrity and public trust decide whether any other risk can be managed at all. This subsite relates the governance, security, societal and information standards that make public decisions traceable, without turning them into scores of countries or people.

The Governance, Security and Society subsite on nexustandards.com, with 8 areas, among them Political and governance risk standards, Conflict and security risk standards, Societal and information risk standards, Geopolitical and security risk, Information integrity and trust, Media and information.

Humanitarian response and development planning serve the same people and places at different horizons. This subsite relates humanitarian, development and global-agenda instruments so that needs, commitments and results can be recorded once and read across organisations in their own public terms.

The Humanitarian Action and Development subsite on nexustandards.com, with 9 areas, among them Humanitarian and civil society, Humanitarian standards alignment, OCHA and humanitarian data, UNDP and development, SDG and 2030 Agenda alignment, International organisations and multilaterals.

Some risks live in the connections between systems, or on horizons beyond any budget cycle. This subsite relates global, catastrophic and long-term risk practice and the scenario and foresight methods that let those risks be stated, compared and revisited as evidence changes.

The Systemic Risks subsite on nexustandards.com, with 4 areas, among them Global and systemic risk, Global catastrophic and existential risk standards, Future generations and long-term risk, Scenarios, models and foresight.

Satellites observe every other system and depend on a space environment that can itself fail. This subsite relates the Earth observation, geospatial and space-sector standards, with STAC as its worked package, so that imagery and the maps derived from it carry their provenance.

The Space and Earth Observation subsite on nexustandards.com, with 4 areas, among them Space industry, UNOOSA and space, Geospatial and Earth observation, Visualization, figures and maps.

Every claim in the ecosystem is only as good as the record behind it. This subsite holds the identifier, data, provenance, statistics, publication, decision-record, privacy and streaming standards, with PROV-O as its worked package.

The Data and Evidence subsite on nexustandards.com, with 8 areas, among them Identification (the UNI), Data and datasets, Provenance and evidence, Indicators and statistics, Documentation and publication, Decision records and accountability.

Assurance here means evidence anyone can check: who evaluated what, against which clause, with which result and when. This subsite holds the identity, supply-chain, verification, conformance and ethics standards, the verification console and the conformance pipeline; it does not certify anything.

The Open Infrastructure and Developers subsite on nexustandards.com, with 11 areas, among them Registries and the resolver, Deployment services, Monitoring services, Developers and APIs, Commons and command rooms, Indexing and discovery.

Adoption is a path, not a badge: an institution, a country or a chapter decides what evidence it needs and reads it under its own rules. This subsite holds the readiness pathways and adoption routes, with the routing console and the composer as the way in.

The Readiness and Adoption subsite on nexustandards.com, with 9 areas, among them Conformance programme, National adoption pathway, Regional chapter pathway, Institutional adoption pathway, Sovereign deployment pathway, For institutional communities.
