The Global Centre for Risk and Innovation (GCRI)
Topics at Critical Infrastructure: the pages in this section are listed below, each with its own scope and status.
GCRI · In development · service level R0
The Critical Infrastructure topics are the nine subject dossiers of its field, among them electricity and lifelines, water and wastewater assets, and telecommunications and cables. Each dossier sets out how the risk develops, what is measured and in which units, the public sources and their licences, the methods, who decides and the limits of the evidence.
GCRI is a research, development and policy institution. It is not a regulator, and it does not certify, license or approve; its findings carry their methods and uncertainty.
The topics cover each lifeline (electricity, water, telecoms, transport, health services, urban assets), then the interdependencies between them and the standards that shape them.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| SAIFI | The System Average Interruption Frequency Index, the average number of interruptions per customer per year. |
| Non-revenue water | Water produced but not billed, including leakage, theft and metering errors. |
| Submarine cable | A fibre-optic cable laid on the seabed that carries telecommunications between landmasses. |
| Logistics node | A place where goods are transferred, stored or processed, such as a port terminal or distribution centre. |
| Safe hospital | A health facility that remains accessible and functioning at maximum capacity during and immediately after a disaster. |
