4.1Risk objects
Each risk is read across the chain from hazard to consequence, with its status and evidence-quality level.
ReportedEQL 3RSK-ZAF-CLI-001
Heavy-rain flooding in a populated province
- Driver
- intense rainfall and cut-off lows
- Exposure
- informal settlements, roads, river corridors
- Vulnerability
- dense low-lying housing; damaged networks
- Capacity
- disaster-management framework; warnings25
- Cascade
- CLI → INF, WAT, HLT
- Horizon
- annual
ReportedEQL 4RSK-ZAF-WAT-002
Wastewater and supply system failure
ReportedEQL 4RSK-ZAF-ENE-003
Electricity supply shortfall
InferredEQL 3RSK-ZAF-CLI-004
Multi-year drought and water restriction
- Driver
- successive dry seasons
- Exposure
- metropolitan supply, irrigated farming
- Vulnerability
- high urban losses; dependence on few dams
- Capacity
- demand management proven in Cape Town 201818
- Cascade
- CLI → WAT → FOO, FIN
- Horizon
- 1–5 years
4.2Capability ladder
Existence is not readiness. Each of the fifteen capability functions is placed on the ladder by the strongest public evidence at baseline.
| Function | Rung | Level | Strongest public evidence at baseline |
|---|---|---|---|
| Prevention and mitigation | NOT BOUND | source: building and land-use records · blocker: not reviewed by evidence close | |
| Monitoring and observation | EXISTS | national wastewater, drinking-water and water-loss assessments are published89 | |
| Early warning | NOT BOUND | source: South African Weather Service and National Disaster Management Centre records · blocker: not retrieved | |
| Preparedness and planning | LISTED | the Disaster Management Act sets the planning framework; its use is not bound25 | |
| Redundancy and reserves | NOT BOUND | source: fuel, water and grain reserve data · blocker: not retrieved | |
| Response | NOT BOUND | source: disaster-response after-action records · blocker: not retrieved | |
| Continuity of critical services | EXISTS | load-shedding energy fell 82% in a year, but water-works power continuity is not bound5 | |
| Recovery | NOT BOUND | source: reconstruction records after the 2022 and 2025 floods · blocker: not retrieved | |
| Adaptation | LISTED | the Climate Change Act provides for adaptation planning; delivery is not bound21 | |
| Social protection | NOT BOUND | source: social-grant and unemployment-insurance records · blocker: not reviewed | |
| Finance and insurance | NOT BOUND | source: Prudential Authority and SARB statistics29 · blocker: not retrieved | |
| Institutional coordination | LISTED | the Disaster Management Act sets national and provincial centres; function is not bound25 | |
| Technical infrastructure | LISTED | wastewater condition documented as critical in 47% of systems9 | |
| Workforce | NOT BOUND | source: municipal engineering and operator registers · blocker: not retrieved | |
| Research capacity | ADEQUATE | a national inventory and a national biodiversity assessment are published213 | |
| A capability listed in policy is not a tested one; each rung is the strongest public evidence at baseline. | |||
