01Scope
Scope and questions
This thematic series comes from the NXS-GRX (canonical data, provenance and risk) mechanism (Nexus, DRR, DRF and DRI architecture).
- Where do the five systems fail together?
- Which couplings are strongest per country?
- Which interventions reduce risk in more than one system?
02Construction
Domain indices to the series index
The series index is the expert-weighted geometric mean of its domain indices, with the intervals and class rule of the methodology.

List
- Water security riskDomain index · IDX · WAT0-10 index of water security risk combining scarcity and stress, WASH access, water quality and transboundary dependence; geometric so that good access does not offset severe scarcity.
- Energy security riskDomain index · IDX · ENEIndex of energy access deficit, fuel import dependence, mix rigidity, supply unreliability and critical-mineral dependence on a 0-10 scale, higher meaning riskier.
- Food insecurity riskDomain index · IDX · FOOWeighted aggregation, on 0 to 10, of acute and chronic food insecurity, food price stress, supply fragility and agricultural dependence.
- Health security riskDomain index · IDX · HLTINFORM-style aggregation, on 0 to 10, of epidemic and AMR hazard, disease burden and undernutrition against health-system and IHR capacity, each component oriented by its own polarity.
- Environmental pressureDomain index · IDX · ENV0-10 index of environmental pressure and ecosystem condition combining air pollution, land and forest degradation, biodiversity status, ocean condition and waste pressure.
- Nexus Interdependency indexSeries index · SERIES · TH-01The water, energy, food, health and biodiversity systems read together: drought to energy stress, energy disruption to health stress, biodiversity loss to food-system stress, flood to water contamination, heat to health and grid stress, cyber-physical disruption across all five.

Each country profile carries the domain indices this series is built from.
Status
The methodology, structure and definitions of The Global Risks Index are a preparatory working draft (2026), circulated for review and comment and not for implementation. No value appears until an edition is released from a governed evidence cut; values then carry intervals, classes, sources and their correction pathway. Simulators run the published methods on numbers you choose and never show a NXS-GRX value.
What NXS-GRX is not
NXS-GRX is research and risk-analytics information. It is not a credit or ESG rating and uses no rating scale, not a benchmark for financial instruments, not official statistics, not an emergency warning or official classification, and not advice. It must not be used to evaluate natural persons. Risk classes are bands on a published scale, never rankings of countries or people.
Institutions and sources
The Nexus Consortium is stewarded by three independent not-for-profit institutions: GCRI Canada as Lead Institution, Consortium Secretariat and lead contracting organization, The Global Risks Forum (GRF) and The Global Risks Alliance (GRA). Technology, infrastructure and service providers work with the Consortium at arm's length under written agreements, like every other external party in the public-private-planet model, and hold no role in its stewardship.
Every value carries the attribution of its sources, which keep their own licences. External names are cited for interoperability only. Nexus-authored text is intended for CC BY 4.0 on release.
Avis en français
La méthodologie et les définitions du NXS-GRX sont un projet de travail préparatoire (2026). Le NXS-GRX est une information de recherche et d'analyse des risques : ni notation, ni indice de référence financier, ni statistique officielle, ni alerte, ni conseil. Les classes de risque sont des bandes sur une échelle publiée, non des classements.
