What this area brings to the editions.
The faculty studies risk that arises from the interdependence of systems, from cascades and complexity to global catastrophic risk. It is the academic home of Nexus-Based Risk Management, the Academy’s paradigm, and of the water-energy-food-ecosystems nexus.
9 findings of the drafted editions that bear on Faculty of Systems and Nexus Studies.
Drawn from the Baseline Edition 2026 drafts through the systems this area reads. Each opens at its anchor in its edition, with its numbered sources.
- JPNJapanThe leading compound pathway for 2027 testing is a large earthquake in an ageing region that cuts water, power, roads and care together.EXPERT INPUT · COUNTRY-JPN-SYS-012
- GLBGlobal SystemsThe leading compound pathway for 2027 testing is a concurrent breadbasket shortfall coinciding with an energy and fertiliser price shock.EXPERT INPUT · GLOBAL-SYSTEMS-SYS-012
- CANCanadaThe leading compound pathway for 2027 testing runs from heat and drought through hydro shortfall, wildfire smoke and rail disruption into health and food logistics in Western Canada.EXPERT INPUT · COUNTRY-CAN-SYS-012
- USAUnited StatesThe leading compound pathway for 2027 testing runs from Western heat and drought through wildfire and grid stress into health, water and insurance availability.EXPERT INPUT · COUNTRY-USA-SYS-012
- GBRUnited KingdomThe leading compound pathway for 2027 testing is a hot, dry summer in which heat, drought, water shortage and grassland fires load health, water, rail and power at once.EXPERT INPUT · COUNTRY-GBR-SYS-012
- FRAFranceThe leading compound pathway for 2027 testing is a hot, dry summer in which low river flows constrain nuclear cooling while heat, drought, wildfire and clay subsidence load health, food and insurance.EXPERT INPUT · COUNTRY-FRA-SYS-012
- DEUGermanyThe leading compound pathway for 2027 testing is a hot, dry summer in which low Rhine water cuts freight and industrial supply while heat, drought and forest fires load health, forests and power.EXPERT INPUT · COUNTRY-DEU-SYS-012
- ITAItalyThe leading compound pathway for 2027 testing is a drought-to-flood year: a hot, dry summer on the Po followed by autumn cloudbursts on dried soils.EXPERT INPUT · COUNTRY-ITA-SYS-012
- GS-01Global WaterThe leading compound pathway for 2027 testing is a multi-basin drought that cuts hydropower and irrigated yields at once while heat raises demand.EXPERT INPUT · SECTOR-WATER-GLOBAL-SYS-012
From Foundry evidence to the series.
The evidence, step by step, from the systems this area reads to the series it feeds.
How Faculty of Systems and Nexus Studies reaches Reports: what it reads, how it reads it, the sealed cut and the series it feeds.
| Step | What happens | Source |
|---|---|---|
| 01 What it reads | Faculty of Systems and Nexus Studies reads The Global Risks Index (NXS-GRX) and NXS-DSS (decision cases and deliberation): governed sources with their releases, never a value without its source. | |
| 02 How it reads them | Systemic, compound and cascading risk and Complex systems and systems modelling turn the evidence into findings, with assumptions and limits stated beside each value. | |
| 03 The cut is sealed | Each quarter the evidence is sealed in one cut, so OBSERVED, REPORTED and ESTIMATED values stay apart and every edition can be rebuilt. | |
| 04 The series it feeds | The cut feeds Global Systems Risk and Resilience and Country Systems Risk and Resilience, from the Baseline Edition 2026 into the quarterly series. | |
| 05 Who decides | Decisions stay with the authorities that hold them, under their own rules; an edition informs a decision and never makes it. |
A teaching model of the evidence path, not a forecast and not a record of any run; the systems, methods and series named come from the registries. Sources: Faculty of Systems and Nexus Studies in Reports (2026); Faculty of Systems and Nexus Studies home (2026).
The series it feeds, and what backs each.
| Series | Foundry systems it draws on | Academy disciplines | Series home |
|---|---|---|---|
| Global Systems Risk and Resilience | NXS-GRX coupled-system cascades and the fused indicator series behind a global synthesis NXS-DSS the cross-field scenario sets an edition compares | Systemic, compound and cascading risk Water-energy-food-ecosystems nexus Global catastrophic risks | Global Systems Risk and Resilience series home |
| Country Systems Risk and Resilience | NXS-GRX one country’s dependency map and its indicator baselines NXS-CMD (integrated posture and executive synthesis) the national portfolio of risk reduction work the edition reads against NXS-EOP (earth observation and digital twins) exposure and change layers at subnational detail | Nexus-Based Risk Management (NRM) Disaster risk reduction Critical infrastructure and lifelines | Country Systems Risk and Resilience series home |
| Regional Systems | NXS-GRX transboundary couplings and the shared indicator series NXS-EOP basin, coast and corridor change products across borders NXS-NET (network topology and continuity) the regional connectivity a shared grid or corridor depends on | Diplomacy, cooperation and the global commons Water-energy-food-ecosystems nexus Climate and nature governance | Regional Systems series home |
| Scenario and Stress-Test | NXS-DSS combined scenario sets and the option appraisals run on them NXS-GRX the cascade paths a stress test follows | Scenario analysis and stress testing Uncertainty and decision making Systemic, compound and cascading risk | Scenario and Stress-Test series home |
| Labs Evidence | NXS-LAB (research, experiments and simulations) what was tried, under which conditions, and what happened, including negative results | Research, evidence and the science-policy interface Complex systems and systems modelling | Labs Evidence series home |

Mirrors and harvest
The DOI is canonical. At release each signed bundle is also given an IPFS content identifier and a bloxberg anchor as mirrors; both are listed in the record once they exist. Zenodo exposes every record over OAI-PMH, and reviews and endorsements can arrive through COAR Notify where the repository supports it.
