Water is the medium through which most climate hazards reach people and the coupling variable of the water-energy-food nexus: floods, droughts and water-quality failures propagate into power generation, irrigation, health and trade. This section of the Water and food systems subsite sets common records for hydrological observations, forecasts, warnings and water-security indicators so that a basin authority, a utility and a ministry can exchange evidence with known provenance, licence and uncertainty rather than incompatible spreadsheets. 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.
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.

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.

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.
GCRI Canada may admit basin observation and forecast records that carry NS-3 record UNIs, station calibration history and stated licences as research evidence; GCRI Canada decides under its own evidence and research rules, and no approval is implied.
GRF may record a basin authority's or utility's adoption of the water profiles as a dialogue item between riparian states; GRF decides under its own recognition rules, and no recognition or endorsement is implied.
GRA may read service-continuity and water-stress records when it assesses resilience investment in utilities; 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.

This area has a row in registry/subsites.yaml (status planned), so it carries five depth pages and the register crosswalk of its domains.
The rules of each listed standard, read through the specification reader.
Depth · CrosswalkEvery register entry in the area's domains, by relation, with the crosswalk graph.
Depth · Records and schemasScope, record, schema explorer and how a UNI resolves.
Depth · ConformanceClauses, evidence and attestations; no step is a certification.
Depth · ReadinessThe area beside the three pathways, as a matrix.
7 Nexus Standards · 5 domains · 50 external standards · 39 issuing bodies · 2 consumers. Relations are register entries (adopt, profile, crosswalk, cite), never compliance claims; names belong to their stewards.
Crosswalk graph103 nodes and 142 links from registry/external-standards.yaml, registry/subsites.yaml and registry/consumers.yaml. Relations (adopt, profile, crosswalk, cite) are register entries, never compliance claims.
The registry holds no geography for the area itself: areas are not places. The one geography it implies is where the bodies that issue the area's external standards sit.

From the ecosystem coverage register: what the GCRI Canada, The Global Risks Forum (GRF) and The Global Risks Alliance (GRA) sites publish on this area, as claimed there and not evaluated here.
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 Water 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.
