DELTA Resilience — Data Sync Architecture for Malawi

How a national resilience data spine reduces the exposure-data lag from 11 days to under 48 hours.

§ Abstract

Malawi's resilience data is not missing — it is siloed. NSO holds population, NDMO holds shelters, MoH holds clinics, NMS holds hazard. None of these systems speak to each other on a cadence that matches a cyclone.

DELTA proposes a thin, open, schema-light spine: nightly snapshots into a shared partition, with event-driven push during active hazards.

The note is deliberately technology-agnostic; the constraint is governance, not stack.

§ Key findings

  • ·Exposure-data lag collapses from 11 days to <48h under nightly snapshots.
  • ·Event-driven push reduces IBF composition window to <90 minutes.
  • ·Data-sharing MoU is the longest-lead item (target: 90 days).

§ Methods

  • →Interface inventory across 6 ministries and parastatals
  • →Schema reconciliation (population, structures, hazard, response)
  • →Latency benchmark on synthetic cyclone trigger
