Geospatial analysis for development finance

Geospatial methods place projects, hazards, people and habitats on a common map. In development finance they support site screening, exposure of assets to climate hazards, safeguard footprints and the location of beneficiaries, with care taken over what can be published.

02Application

What geospatial information systems does here.

Geospatial information systems capture, store, analyse and present location-referenced data. They provide the common spatial frame for combining hazard, exposure and vulnerability information. In development finance, critical infrastructure and economic development, geospatial analysis identifies where hazards overlap critical assets and vulnerable populations. It supports location-based planning across infrastructure, health and finance. The canonical description is on the STEM Commons.

Safeguard screening of a project footprint

Alignments and sites are overlaid on protected areas, key biodiversity areas, settlements and land tenure layers to set the classification and the scope of assessment.

Physical climate exposure of assets

Asset locations are intersected with flood, heat, drought and cyclone hazard layers by return period to estimate exposure and downtime for design and credit review.

Locating beneficiaries and gaps

Gridded population, service locations and travel time are combined to show who a programme reaches and where coverage gaps remain.

03Spatial finance

06Validation

How results are checked.

Positional and attribute accuracy are checked against surveyed control points and reference datasets. Topology rules and metadata standards ensure consistency.

CheckHow it is done
Positional accuracyProject locations are checked against documents; geocoding precision is recorded for each point
Common projectionAll layers are reprojected to a common equal-area grid before overlay
Disclosure reviewPublished maps are generalised so that no household, complainant or sensitive site can be identified

Errors in projection, scale and data currency propagate through analysis. Aggregation to administrative units can mask local variation.

07Scenario model

Policy paths and what they do to the risk.

How three families of instruments change a risk outcome over time with adoption lags, coverage and compliance, the policy scenarios behind transition and physical risk assessments. Scenario: named assumptions about the future, not a forecast. The map on this page shows Southern Africa; the model itself is not tied to a place.

09Twin and cascade simulator

Trace a shock in geospatial analysis for development finance to the balance sheet.

Assembled from the Nexus Standards area profile Disaster and climate risk finance: the shocks it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Pick an initiating shock and step through the cascade to see which exposures it reaches and where losses could concentrate. The Map view places the run on an example geography with open data. Every weight is a stated assumption. An exercise, not a forecast, a valuation, a rating or investment advice. To model a place of your own choosing, open the full System Builder.
