Risks and capability
Four regional risk objects open the portfolio. Order carries no rank. Each is read across driver, exposure, vulnerability, capacity, cascade and consequence; loss metrics are added only where they can be modelled.

4.1Risk objects
Each risk is read across the chain from hazard to consequence, with its status and evidence-quality level.

4.2Capability ladder
Existence is not readiness. Each of the fifteen capability functions is placed on the ladder by the strongest public evidence at the regional level, from a policy listing to performance in real events.
| Function | Rung | Level | Strongest public evidence at baseline |
|---|---|---|---|
| Prevention and mitigation | EXISTS | national inventories and reduction reporting are published1416 | |
| Monitoring and observation | EXISTS | statistical series are published1; reservoir and drought records are not bound at the close | |
| Early warning | NOT BOUND | source: weather and flood-warning services · blocker: not retrieved | |
| Preparedness and planning | LISTED | Colorado River decision record and 2027 to 2028 guidelines issued19; delivery not bound | |
| Redundancy and reserves | NOT BOUND | source: gas storage and reserve margin data · blocker: not retrieved | |
| Response | NOT BOUND | source: after-action records for fire and drought events · blocker: not retrieved | |
| Continuity of critical services | LISTED | reliability organisation exists30; performance not bound | |
| Recovery | NOT BOUND | source: recovery agency and insurer records · blocker: not retrieved | |
| Adaptation | LISTED | international water treaties and commissions exist273536; delivery not bound | |
| Social protection | NOT BOUND | source: income-support and disaster-payment records · blocker: not reviewed | |
| Finance and insurance | NOT BOUND | source: insurer and reinsurer loss data3133 · blocker: not retrieved | |
| Institutional coordination | EXISTS | the International Joint Commission and the boundary and water commission exist2327; performance not bound | |
| Technical infrastructure | NOT BOUND | source: asset-condition registers · blocker: not published | |
| Workforce | NOT BOUND | source: health and emergency workforce registers · blocker: not retrieved | |
| Research capacity | EXISTS | peer-reviewed compound-event and nexus research is published4142 | |
| A capability listed in policy is not a tested one; each rung is the strongest public evidence at baseline. | |||
