Cities concentrate population, assets and interdependent services, so hazards become disasters where urban exposure, informal settlement and fragile networks meet. This section of the Cities and the Built Environment subsite sets records for urban exposure, settlement and building stock, urban heat and flood, and service networks so that municipalities, planners and investors analyse urban risk with consistent urban definitions and traceable inputs. Every artifact of the area carries a UNI (Unique Nexus Identifier), which identifies and never certifies.

Jurisdictions No jurisdiction note is recorded for this area yet; jurisdiction narrows what applies and never implies that a Nexus profile satisfies a law.
Each coupling names the mechanism that links this area to another; select a card on the canvas to trace it. Mechanisms are stated in the context bank (PROPOSED).
Fig.RUNNING marks the area you are reading; DONE an area in the same subsite, QUEUED an area elsewhere and GATE a subsite reached. Tags give reading order only, never a status. Design, not a record.

Sources the area reads or proposes. Delivery follows GRIx first; a source is shown live only after an owner decision admits it for public pages.
No legal register row admits any of these sources for live display on public pages yet, so nothing is read from them here. A register row that exists records the source for the governed GRIx path; admission for public pages is a separate owner decision.

Relations are register entries (NS-14), never conformance or equivalence statements; hover or focus a relation for its meaning. Names of standards bodies and their standards belong to their stewards and are used only to identify the documents; no text of an external standard is reproduced here.
Indicator names and codes as their stewards publish them; values appear only from a governed GRIx source, never typed into a page.
The Nexus Standards the area context entry lists. Every one is proposed or specified; none is adopted by an authority.

Closed or paywalled standards appear by name and link only; any compatibility profile of one is built on simulated data and kept on protected pages until an institutional arrangement with the issuing body is recorded. Nexus Standards is not affiliated with, endorsed by or certified by any standards body named here.
The working group may name closed standards later; they would be listed here by name and link only.
GCRI Canada may admit urban exposure records that state footprint source, date and completeness as research evidence; GCRI Canada decides under its own evidence and research rules, and no approval is implied.
GRF may record municipalities that adopt the urban records in local DRR strategies as a recognition dialogue; GRF decides under its own recognition rules, and no recognition or endorsement is implied.
GRA may read urban exposure and service-network records when it considers municipal resilience finance; GRA decides under its own capital-readiness rules, and no approval, rating or investment view is implied.
Each institution decides under its own rules what it reads as evidence; no pathway is an approval, a readiness statement or investment advice.
Version and feed state per standard; every row reads source feed pending admission until a register row admits a feed.

Peer-reviewed sources and published statistics on the publishers' own domains, as the context entry cites them. No Risk Academy faculty pathway is linked to this area yet; one is linked when a faculty publishes a pathway that fits.
Risk Academy disciplines that teach Cities and urban systems risk standards, with their courses; the GCRI Canada, The Global Risks Forum (GRF) and The Global Risks Alliance (GRA) subsites that carry those disciplines; and the Nexus Foundry systems the standards name. Mappings are proposed for review (Risk Academy standards map, 2026-10-17); a link says a page on the same subject exists, never an endorsement or a conformance statement; framework names in course titles are named and linked, never reproduced.
Propose a change, join the working group or name a source. Area entries are PROPOSED content for the Nexus Standards registry; a UNI identifies and never certifies, and nothing on this site is a certification, an approval or a readiness statement.
