Infrastructure dependencies
Power, water, transport, ports, telecommunications, data centres and payment systems are lifelines: when one fails, the others feel it within hours. Most depend on electricity and digital control, and many share the same corridors, suppliers and skilled operators. The Global Centre for Risk and Innovation (GCRI) studies these physical and digital dependencies, the single points of failure that turn local events into national ones, and the bottlenecks that slow recovery. This page is part of global challenges.

The short answer.
Infrastructure dependencies are the physical and digital links between lifelines such as power, water, transport, ports, telecommunications, data centres and payment systems, so that when one fails the others feel it within hours. GCRI studies these dependencies and the single points of failure that turn local events into wide disruption, keeping restricted operator detail restricted.
Infrastructure networks in Kenya.
Major roads, railways, ports and airports, and the density of the transport network, shown for Kenya as an example geography for this subject.
Lifelines depend on each other more than their owners can see.
Everything needs power
Water treatment, hospitals, cold chains, communications and payments all stop when the grid fails, and the grid needs communications and water to restart.
Hidden single points
A shared substation, cable landing, fuel terminal or cloud region can sit beneath services that appear independent.
Bottlenecks after the event
Spare transformers, specialist crews, fuel logistics and access routes often decide how long an outage lasts.
From dependency maps to tested options.
- 01
Map dependencies
Which services depend on which assets, suppliers and operators, using network science and systems engineering.
- 02
Find common-mode failure
Where one hazard, failure or attack can disable several systems at once.
- 03
Test under stress
Controlled scenarios using reliability and resilience engineering, with results labelled as modelled.
- 04
Hand off to the operator
Options and their limits go to the operator or authority that decides. GCRI never operates infrastructure.
Restricted detail stays restricted.
Infrastructure studies often involve sensitive topology. Public pages describe mechanisms and published findings only; operator data is used under agreed terms and never appears in public examples. Membership of a programme never grants access to production systems.
GCRI does not regulate, inspect or certify infrastructure.
Terms used on this page.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Critical infrastructure | The physical structures, facilities, networks and assets that provide services essential to the functioning of society and the economy. |
| Interdependency | A two-way dependency between infrastructures, such as power needing telecoms for control while telecoms need power to run. |
| Single point of failure | A component or supplier whose loss stops a function because no substitute exists. |
| Lifeline | An infrastructure system, such as power, water or telecommunications, whose service other systems and people need continuously. |
Fields, platforms and counterparts.
Field work is organized through the Critical Infrastructure platform, in development, and the critical infrastructure field gateway. Operators can start at infrastructure and industry. The Global Risks Alliance (GRA) examines the finance questions under infrastructure preparedness. See also digital and cyber dependencies.
