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:
- Day 2 Deck 1v1 — Demo Area
- Day 2 Deck 1v2 — Irrigated Agriculture Project
- Day 2 Deck 1v3 — Road Project
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.
