Morning — Spatializing IsDB Projects (PCN–PCR)

Day 2 · 09:00–12:30 · Modules 2 & 3


Session 4 — Spatializing IsDB Projects from PCN to PCR (09:00–10:30)

Slide decks — three worked examples of the same framework:


The spatialisation procedure: PCN to PCR

Day 2 introduced a step-by-step procedure for spatialising a project through its full lifecycle. The same boundary and data approach applies regardless of sector — agriculture, water, infrastructure, health, education.

What to collect at each stage:

Stage Document What to collect How to get it
Identification PCN Site coordinates / rough boundary · feasibility layers Google Earth Web · GADM · GeoBoundaries
Preparation PPRR Refined boundary · area of influence Google Earth KML export · admin boundary download
Design PAD / RRM Detailed boundary · hazard/land-use/climate layers eToolkit · WaPOR · EarthMap
Supervision PIASR Same boundary + monitoring period eToolkit (same boundary, new time window)
Completion PCR Same boundary + end-line date eToolkit baseline vs end-line comparison
Post-evaluation PPER Same boundary + 3–5 years post-completion Long-term trend from eToolkit / GEIDA platform

Why the same boundary matters

From PCN to PPER there can be a gap of 10+ years. If you don't store the same spatial boundary in a project database, you lose the ability to make a before/after comparison at evaluation. The Minimum Project Data Submission Form (introduced on Day 3) is the first step to fixing this.

Three worked examples

The three versions of the Day 2 slide deck demonstrate the same approach for:

A generic project area used to introduce the methodology — shows how to go from a text description to a boundary, then to an eToolkit report, step by step.

An irrigation scheme project: boundary corresponds to the command area. Key indicators: ETa (actual evapotranspiration), root zone soil moisture (RZSM), surface water extent, LULC. Relevant documents: PAD (environmental baseline, water availability), PIASR (crop status, irrigation efficiency), PCR (irrigated area change before/after).

A road corridor project: the spatial element is a line plus a buffer (e.g. 1–5 km). Key indicators: land cover within buffer, flood risk, population exposure, settlement density. Relevant documents: PCN (feasibility, hazard screen), PAD (alignment options, environmental assessment), PCR (construction verification), PPER (infrastructure intact, economic activity change).


Bio-physical EO analysis (10:00–10:30)

Earth Observation provides a range of bio-physical indicators that map directly onto IsDB sectors:

Indicator What it measures Relevant sector(s)
RZSM (Relative Root Zone Soil Moisture) Soil moisture availability in the root zone Agriculture · Water · Environment
ETa (Actual Evapotranspiration) Water used by vegetation and bare soil Agriculture · Water · Irrigation
Surface water extent Mapped water bodies and change over time Water · WASH · Flood risk
Land Use / Land Cover (LULC) Classification of surface types All sectors
Topography / DEM Elevation and slope Infrastructure · Flood risk · Agriculture
Nighttime lights Human activity, electrification Energy · Urban · Economic development
Precipitation trends Rainfall over time Agriculture · Water · Climate
Temperature change Surface temperature trends Climate · Health · Infrastructure

Exercise 2 — eToolkit Continued (11:30–12:30)

Building on Exercise 1, participants applied the eToolkit to a more specific project-relevant area — selecting the correct Theme for their sector and a relevant Phase to get outputs aligned to an actual project document.

Key difference from Exercise 1: move from a generic "identify an area" to a sector-specific analysis:

  • Agriculture project → select Agriculture theme → ETa, root zone soil moisture (RZSM), water productivity outputs become more relevant
  • Infrastructure project → select Infrastructure → LULC, flood risk, climate projections emphasised
  • Water project → select Water → surface water, precipitation, groundwater trend outputs

Participants also explored using a project boundary from GADM (downloaded as GeoJSON, imported into eToolkit) rather than drawing one manually.
