4.1Risk objects

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

  1. 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
  2. ReportedEQL 4RSK-ZAF-WAT-002

    Wastewater and supply system failure

    Driver
    poor maintenance, power loss, flood damage
    Exposure
    rivers and towns downstream of critical systems
    Vulnerability
    47% of systems critical9
    Capacity
    Green and Blue Drop oversight; turnaround evidence not bound
    Cascade
    WAT → HLT, BIO, FOO
    Horizon
    1–5 years
  3. ReportedEQL 4RSK-ZAF-ENE-003

    Electricity supply shortfall

    Driver
    low fleet availability and demand peaks
    Exposure
    water works, clinics, industry, households
    Vulnerability
    availability near 58%5
    Capacity
    load-shedding fell 82% in a year; new capacity528
    Cascade
    ENE → WAT, HLT, FIN
    Horizon
    1–5 years
  4. 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.

Table 4.1Capabilities on the ladder of evidence: listed, exists, demonstrated, tested
FunctionRungLevelStrongest public evidence at baseline
Prevention and mitigationNOT BOUNDsource: building and land-use records · blocker: not reviewed by evidence close

Finance and insuranceNOT BOUNDsource: Prudential Authority and SARB statistics29 · blocker: not retrieved
Institutional coordinationLISTEDthe Disaster Management Act sets national and provincial centres; function is not bound25

WorkforceNOT BOUNDsource: municipal engineering and operator registers · blocker: not retrieved
Research capacityADEQUATEa 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.
