Engine & Framework

Deterministic. Reproducible. Auditable. Every result can be re-run from the same inputs and will return the same output.

◆ Inkanyamba

Named after a storm-force from Southern African tradition — Inkanyamba appears when systems are under stress and decisions cannot wait. That is exactly the context this engine is built for.

Early Warning

Purpose

Early warning tracks signals that conditions are changing before a full response decision is made. It sits between baseline preparedness and emergency response — watching for the shifts that mean a reassessment is needed.

What This Section Holds

Key Concepts & Definitions

Term Definition
Risk Signal Indicator of a potential change in hazard intensity, exposure, or vulnerability.
Reassessment Trigger Pre‑defined rule that flags a need to revisit baseline assumptions.
Alert Level Graded severity (Info, Watch, Warning, Emergency) based on signal confidence.

Process Flow

  1. Signal Ingestion – Automated feeds from weather services, market data, and incident reports.
  2. Normalization & Scoring – Convert raw feeds into CDI‑compatible risk scores.
  3. Threshold Evaluation – Compare scores against trigger thresholds.
  4. Alert Generation – Create alerts and update the Early‑Warning dashboard.
  5. Stakeholder Notification – Notify municipal partners via email/WhatsApp when a trigger fires.

Evidence & Data Sources

Decision Brief Template

Signal Summary – Rising river levels (Risk Score: 0.78) crossing Reassessment Trigger.

Implication – Potential flood impact on transport corridors; baseline accessibility assumptions may no longer hold.

Recommendation – Initiate rapid feasibility check in Emergency Response phase.
