Also: enrichment dependency, fuel fabrication bottleneck

A shortage of ships, containers, trucks or crews that drives freight costs up and delays deliveries worldwide.

Growing swings in orders and stocks moving up a supply chain, as each stage overreacts, producing alternating gluts and shortages.

Sudden loss or restriction of minerals concentrated in few countries, such as lithium, cobalt, rare earths or gallium, stalling batteries, electronics, defence and grids.

Also: rare earth shortage, battery metal shortage

Sharp loss or price spike in nitrogen, phosphate or potash fertiliser, from gas prices, sanctions or export bans, cutting yields in the following seasons.

A failure in one infrastructure system that spreads through dependency links to power, water, transport, communications and health.

Also: critical infrastructure failure, cascading failure

Loss of electricity that stops, in turn, pumps, signalling, telecom masts, refrigeration and hospital support.

Also: blackout knock-on

A shock to one of water, energy or food supply that propagates to the others through shared inputs, such as power for pumping and water for cooling.

Also: nexus shock

Spread of a financial shock between institutions, markets and countries through shared exposures and loss of confidence.

Also: market contagion

Demand for care exceeding capacity, from a surge of cases or injuries or from loss of staff and supplies, so that avoidable deaths rise.

Also: hospital surge, care capacity exceeded

Simultaneous demands that exceed the capacity of rescue, relief and coordination, delaying aid.

Also: responder saturation

Loss of a digital service, such as payments, cloud, identity or navigation, that stops the physical services built on it, from fuel pumps and pharmacies to logistics and power control.

Also: IT outage knock-on, digital service cascade

A blocked restart in which power, telecoms, fuel and water each need another to recover first, prolonging a widespread outage.

Also: circular dependency, restoration interdependency

A grid disturbance in one country that spreads across interconnections and splits or blacks out a multinational power system.

Also: interconnected grid disturbance, synchronous area split

A loop in which physical damage or risk prompts insurers, lenders and investors to withdraw, which blocks repair and adaptation and raises future physical losses.

Also: insurance retreat spiral, climate asset repricing loop.

Flooding made worse by two or more drivers acting together, such as storm surge with heavy rain or high river flow.

Also: surge and rain flooding, coincident flooding

A hot spell on dry soils in which heat and water deficit reinforce each other, cutting crops and raising fire and power-demand risk.

Also: hot-dry extreme

Harvest failure in several major producing regions in the same season, tightening global food supply.

Also: multiple breadbasket failure

Extreme cold that raises heating demand while freezing or limiting fuel and generation, risking blackouts.

Also: winter blackout risk

Extreme heat that raises cooling demand while lowering line and plant capacity and river-cooling margins.

Also: summer peak stress

A technological accident, such as a toxic release, fire or explosion, triggered when a natural hazard damages a plant, pipeline or store.

Also: natural-hazard-triggered technological accident

Back-to-back hazards in the same place before recovery, so that damage and vulnerability accumulate.

Also: back-to-back disasters

A natural or technological disaster striking during an outbreak, which blocks distancing, care and supply and may seed new spread.

Also: disaster in a pandemic

Armed conflict combined with drought, flood or other climate stress in the same place, which multiplies food and displacement crises.

Also: climate-conflict nexus

Dependence of a service, region or industry on one asset, site, route or provider whose loss stops the whole, with no tested alternative.

Also: critical node, sole route

Concentration of critical digital, financial or logistic services in very few providers, so that one provider’s failure becomes a failure of whole sectors.

Also: cloud concentration, hyperscale dependency, Critical digital-provider concentration, vendor lock-in, compute concentration.

Failure of supposedly independent backups or systems together because they share a design, supplier, software, location or hazard exposure.

Also: shared-cause failure, correlated failure, single point of failure.

Also: software monoculture, uniform platform dependence, Software monoculture failure, faulty mass update, common-mode software fault.

Operating with minimal stocks and spare capacity for efficiency, which leaves supply chains and services with no buffer when a flow is interrupted.
