Six evidence streams, each with a defined role and defined limit. Combined per the integration matrix below to produce a 4-tier confidence rating.

What it captures

Household-level outcome measures, sub-group disaggregation, comparison to reference sites.

Sample

Phase 1: 600 HH (primary endline instrument). Phase 2: 120 profiles (rapid, not for long-term claims).

Feeds outcome areas
  • · Environmental & Water Resource
  • · Soil & Agricultural
  • · Economic & Livelihood
  • · Social & Gender
CAPI-based. In Phase 2, treat as profiling only.
