Risks cascade across systems
Water, energy, food, health, ecosystems and infrastructure fail together through shared dependencies. Assessments made one sector at a time miss the compound events that do the most damage.
The Global Centre for Risk and Innovation (GCRI) is the Lead Institution of the Nexus Consortium and its technical office. It builds the science, the models and the evidence standard that countries use to see systemic risk, test their options and decide. GCRI Canada holds the Secretariat and contracts for the Consortium; GCRI US is a separate institution with its own mandate.
The institutional record · service level R0
A drought becomes a power shortage, a food price shock and a health emergency. A software failure halts ports, payments and hospitals at once. Mandates, data and budgets stay divided by sector and border, so the risks that matter most are the ones nobody examines whole.
Water, energy, food, health, ecosystems and infrastructure fail together through shared dependencies. Assessments made one sector at a time miss the compound events that do the most damage.
Artificial intelligence, biotechnology, quantum and autonomous systems create new capability and new exposure faster than institutions can evaluate, govern or absorb them.
Ministries, operators and financial institutions often decide without shared evidence, tested options or a clear view of uncertainty. Finance for resilience follows events instead of preparing for them.
GCRI is the Consortium's technical office. It turns a national question into science others can examine, technology others can test and options a competent institution can adopt.
Multi-hazard and climate risk science, systemic and cascading risk, strategic foresight on emerging risk, and country evidence published with its methods and uncertainty.
The shared Nexus Foundry environment, earth observation and geospatial intelligence, sovereign data and AI, shared computing, and resilience engineering for critical infrastructure and cyber systems.
Evidence and technical options for public decisions: risk governance, adaptation, digital and AI governance, interoperable data and methods, and technical assistance to the institutions that decide.
GCRI supplies the technical basis. Policy dialogue and convening are led by GRF, finance readiness by GRA, and every decision stays with the competent authority.

We start from the dependencies between water, energy, food, health, biodiversity and critical infrastructure. We trace how stress in one system reaches the others, find the shared points of failure and test which interventions strengthen several systems at once. Select a system to see what it depends on and what it takes down with it.
Fig. 02Six systems, each coupled to every other.
Drought, flood and contamination, and the dependence of power, irrigation, sanitation and industry on the same basins.
Rainfall and groundwater, ecosystems that regulate flow, and energy for pumping and treatment
Power generation and cooling, irrigated food production, sanitation and health, industrial supply
How a cascade unfolds. A drought lowers reservoirs, hydropower and thermal plant cooling fall, and water treatment loses power at the moment demand peaks.
Grid stability, fuel and critical mineral supply, and the transition, with the water, cooling and digital systems that energy depends on.
Water for cooling and hydropower, fuels and minerals, digital control systems
Every lifeline: water treatment, hospitals, food cold chains, communications and payments
How a cascade unfolds. A heatwave raises demand while cooling water warms, forcing curtailment that cascades into water, health and digital services.
Yield shocks, input and logistics disruption, price transmission and nutrition, from field to cold chain to household.
Water, soils and pollinators, fertiliser and fuel, ports and cold chains
Nutrition and health, household finances, social stability and public budgets
How a cascade unfolds. A drought and an export restriction coincide, prices spike, and nutrition and public finances absorb the shock for years.
Outbreaks, heat and pollution, and the continuity of hospitals that rely on power, water, supply chains and data.
Clean water and sanitation, reliable power, medical supply chains, digital records and a healthy environment
Workforce and productivity, household income, education and public trust
How a cascade unfolds. Extreme heat raises admissions while power cuts disable cooling and records, and pharmaceutical supply chains slow.
The ecosystem services that regulate water, soils, pollination and disease, and the land-use choices that erode or restore them.
Land-use policy, water flows, climate and pollution levels
Water regulation, food yields, disease control, coastal protection and livelihoods
How a cascade unfolds. Upstream deforestation raises flood peaks and sediment, damaging water treatment, hydropower reservoirs and downstream farms.
Transport, ports, communications, data centres and payment systems, where single points of failure turn local events into national ones.
Power, water, skilled operators, software supply chains and satellite services
Trade and food logistics, health supply chains, emergency coordination and finance
How a cascade unfolds. A port outage halts fuel and food imports, while a regional data-centre failure stops customs, payments and hospital records together.
Every pair of systems is coupled in both directions. Each row shows how stress in one system reaches the others.
| From · to | Water | Energy | Food | Health | Biodiversity | Infrastructure |
|---|---|---|---|---|---|---|
| Water | Hydropower, thermal cooling | Irrigation, livestock | Drinking water, sanitation | River flows, wetlands | Treatment, ports and navigation | |
| Energy | Pumping, treatment, desalination | Fertiliser, cold chain | Hospital power, cooling | Land use, emissions | Every lifeline | |
| Food | Irrigation demand, runoff | Biofuels, processing demand | Nutrition, food safety | Land conversion, pesticides | Freight, storage, ports | |
| Health | Outbreak response, workforce | Workforce availability | Labour, food safety | Zoonotic pathways | Workforce, surge demand | |
| Biodiversity | Watershed regulation | Reservoir sediment, biomass | Pollination, soils | Disease regulation, medicines | Coastal protection, flood buffering | |
| Infrastructure | Networks, control systems | Grid control, fuel logistics | Logistics, cold chain, markets | Supply chains, records, access | Fragmentation, spills |
Fig. 03The channels through which stress passes between systems. Mechanisms, not measured strengths.
Each analysis states the systems it couples, the mechanism of transmission and the assumptions behind it. A dependency map is never presented as a validated causal model.
Observed, published statistics, estimated, modelled, forecast and scenario results carry their own labels. Missing data is shown as missing, never as zero.
We examine how events combine and propagate, how long recovery takes and which constraints bind, rather than scoring hazards one at a time.
Questions come from national demand and local knowledge, analysed at the scale where consequences are felt, with rights-holders involved on their own terms.
Findings move into controlled exercises, portfolio choices and handoffs to the institutions that act, and the results return as corrections for the next cycle.
The sectors drought touches and how strongly they depend on each other: what a study has to observe and model together.

Every programme runs the same eight steps. GCRI leads the evidence and the build, runs the technical office for the annual test and hands each decision to the institution that holds it.
Fig. 04A computational graph of the Nexus cycle: nodes with their type, metrics and state, connectors for what feeds what, the owners as groups, the year as a run timeline. Design, not a record of a run.
GCRI stewards the shared infrastructure national and regional programmes run on. Every country works with the same methods and the same evidence standard, and keeps its own data under its own control.
The whole architecture: consortiums, platform, annual programme, shared computing and publications, working as one programme. GCRI keeps its records, registers and technical coherence.
The operating environment where projects, data, models, maps, analysis and evidence persist all year, in twenty systems with ten command rooms each. GCRI runs its global-to-local deployment under a strict not-for-profit mandate.
The annual operating and proving cycle governed by GRF, with its own website. GCRI provides the technical office: mission scoping, data and method qualification, the Core build and evidence capture. The final stage is a planned stand-down; review, reconciliation and corrections continue afterwards.
A durable federation of retained national and regional sites, and each year a temporary Core of qualified computing, high-speed networks and technical teams. Offered capacity is never counted as allocated capacity.
One governed publication programme: quarterly country editions, an annual flagship and specialist series, with methods, uncertainty, review and correction history. GCRI stewards the evidence and methods behind every edition.

Global risks reach a country through specific systems. Every national programme examines the same twelve domains, so findings compare across borders without collapsing into one score.
| Family | Domains | What we examine |
|---|---|---|
| Environmental | Climate and hazards · Water · Biodiversity and land · Food | Compound hazards, resource stress, ecosystem loss and the limits of adaptation |
| Societal | Health and biosecurity | Outbreaks, health-system continuity, heat and pollution, and unequal exposure |
| Infrastructure | Energy · Lifeline infrastructure · Critical minerals | Single points of failure, restoration constraints and supply concentration |
| Economic | Trade and supply chains · Finance and insurance | Chokepoints, price transmission, protection gaps and fiscal exposure |
| Technological | AI and cyber · Data and compute | Digital dependence, provider concentration, cyber disruption and AI failure modes |
Each frontier technology changes what can go wrong and what a country can do about it. We assess both sides against real use cases, real operating conditions and the skills a country actually has.
Failure modes, misuse, concentration of models and compute, and automated decisions without accountability
Forecasting, risk intelligence and decision support under human oversight
Future threats to today's encryption and the long transition to quantum-safe systems
Optimization and simulation for networks, materials and logistics
Safety in shared spaces, cyber-physical attack and accountability for autonomous action
Inspection, response and operations where people should not go
Biosafety, biosecurity and dual-use research
Diagnostics, vaccines and resilient agriculture
Supply concentration, export controls and the energy and water demands of data centres
Sovereign computing environments with a portability and exit plan
Dependence on satellite services and signal disruption
Earth observation, monitoring and verification at national scale
Critical mineral dependence and the safety of new energy systems
Storage, grid flexibility and resilient construction
Network concentration, interception and cascading outages
Resilient connectivity for warning, response and continuity
A technology's novelty or a vendor's benchmark does not establish its fitness for a national mission. Capabilities still in research are labelled as research.
Each country builds its own National Nexus programme with accountable national counterparts. GCRI supplies the technical backbone, so national work meets one standard and compares across borders.
A formation dossier with the local ownership model, host options, first risk questions, safeguards, resources and exit conditions.
Coordination, routing, cadence, records and continuity for the country programme.

Missions tested each year in Nexus Universe, and progress published in the quarterly Nexus Country Systems Risk and Resilience Report.
The Africa programme is designed around the systems that cross the continent's borders: transboundary river basins, regional power pools, trade and mineral corridors, food and pastoral systems, and cross-border health. Country programmes set the agenda; regional work compares compatible evidence so each government, operator and community can decide with a clearer view of what it depends on.
| Planned hub | Focus |
|---|---|
| Senegal | Sahel and coastal dependencies, basins, food, water, energy and regional capability development. |
| Kenya | Drought, pastoral systems, geothermal energy, health, ports and regional connectivity. |
| South Africa | Water, energy and mining dependencies, municipal systems, industrial continuity and transition. |
The Asia and the Pacific programme spans dense manufacturing and logistics networks, large monsoon and glacier-fed basins, and Pacific island states facing compound climate and connectivity risk. The East Asia Nexus Consortium programme, in formation, sits within this region. Work is organised by subregion so that national programmes can compare semiconductor, port, energy and hazard dependencies without merging their data or authority.
| Planned hub | Focus |
|---|---|
| India | Monsoon and heat, river systems, food, health, digital infrastructure, grids and Indian Ocean connections. |
| Singapore | Import dependencies, ports, urban continuity, digital systems and finance. |
| Japan | Seismic and tsunami resilience, manufacturing, robotics, ageing, energy and supply chains. |
The Europe and Eurasia programme covers highly interconnected power, gas, data and transport systems, alongside the Caucasus and Central Asian corridors that link Europe to Asia. The Eurasia Nexus Consortium programme, in formation, sits within this region. Regional work focuses on cascading infrastructure failure, the energy transition, heat and flood risk, and the digital and financial dependencies that cross jurisdictions.
| Planned hub | Focus |
|---|---|
| United Kingdom | Four-nation context, coastal and North Sea systems, infrastructure continuity and finance readiness. |
| France | Metropolitan and overseas contexts, Mediterranean systems, grids and European interoperability. |
| Switzerland | Alpine systems, watersheds, methods, standards, international institutional interfaces and finance readiness. |
| Türkiye | Seismic resilience, cities, reconstruction readiness and strategic corridors. |
The Latin America and the Caribbean programme connects the Amazon and Andean water systems, major agricultural export corridors, and Caribbean and Central American states exposed to hurricanes, sea-level rise and seismic risk. Country programmes lead; regional work makes evidence compatible across basins, ports and power systems so that small and large states can test the same questions on their own terms.
| Planned hub | Focus |
|---|---|
| Brazil | Amazon and basin systems, biodiversity, food, energy, land and bioeconomy dependencies. |
The Middle East and North Africa programme addresses severely water-stressed systems, the transition of major energy economies, extreme heat, and maritime and overland corridors of international importance. North African states also take part in the Africa programme. Regional work compares desalination, groundwater, power, food-import and heat dependencies while each country keeps control of its data and its decisions.
| Planned hub | Focus |
|---|---|
| United Arab Emirates | Heat, desalination, power, compute, ports, logistics and development readiness. |
| Saudi Arabia | Heat, water, cities, industrial systems, compute and Red Sea dependencies. |
The North America programme covers deeply integrated electricity, energy, transport and manufacturing systems across Canada, the United States and Mexico, together with wildfire, heat, flood, hurricane and Arctic change. The Consortium Secretariat sits with GCRI Canada in Toronto, and the Canada Nexus Consortium programme, in formation, sits within this region. Mexico also takes part in the Latin America and the Caribbean programme.
| Planned hub | Focus |
|---|---|
| Canada | National adaptation, sovereign compute, Indigenous and Arctic interfaces, infrastructure and North American coordination. |
| United States | Federal, state, Tribal and territorial interfaces; power, digital infrastructure, hazard resilience and supply chains. |
Nexus Reports puts country risk, capability and the National Portfolio into one continuing record. Each quarter answers one defined question; the fourth edition is the annual flagship.
What matters this year, and what is the starting position?
What new evidence and capability have been developed?
What do scenarios and tests reveal?
What did the year establish, and what changes next?
A planned report appears as a publication intention, never as a cover without a release. Release follows review, not publicity deadlines.

A reference institution is trusted for what others can check, not for what it says about itself. Six commitments govern everything GCRI publishes.
We state what has been observed, estimated, modelled or assumed, with its uncertainty, before we state a conclusion.
A role, a partnership or a capability exists when a record shows it. A logo, a meeting or a plan is not that record.
Work passes to a decision-maker only when it is fit for that step, with its limits stated beside its findings.
No funder, sponsor, member or host can buy a finding, a ranking, an appointment or the suppression of a limitation.
We prepare evidence. Governments, operators and licensed institutions decide and act under their own authority.
Anyone can challenge a public finding without membership or payment. A correction creates a new recorded version, never a silent edit.
| Decision | Who is accountable | What that means |
|---|---|---|
| Consortium Secretariat and contracting | GCRI Canada, as Lead Institution and lead contracting organization | One coordinated programme with separate institutional responsibilities |
| Evidence, methods and technical assistance | GCRI technical and evidence stewardship | National questions become testable work and reusable capability |
| National agenda and participation | Competent National Nexus structures | National ownership precedes federation |
| Scientific and editorial acceptance | Qualified, conflict-managed reviewers and the publisher | Findings are accepted on method, not on who funded or hosted the work |
| Decisions of the authorities and execution | The relevant government, operator or licensed institution | Nexus prepares evidence and supports lawful continuation |
