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.

Spatial financeWhere capital meets hazard, exposure and transition
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.
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.
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.
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.
Gridded population, service locations and travel time are combined to show who a programme reaches and where coverage gaps remain.

Datasets and records used by geospatial information systems on this platform, with the role each plays and the label its values carry. Sources are listed in the source register.
| Data | Role | Label |
|---|---|---|
| Gridded population | Exposure and beneficiary counts | ESTIMATED |
| Hazard layers by return period | Physical risk to assets | MODELLED |
| Protected area and biodiversity layers | Safeguard screening | Published statistics |
| Administrative boundaries | Reporting units | Published statistics |
| Project location data from IATI and MDB portals | Where finance goes | REPORTED |
The screen a team would use to follow this method: its measures, states and decisions. Names are examples and values are illustrative.
Positional and attribute accuracy are checked against surveyed control points and reference datasets. Topology rules and metadata standards ensure consistency.
| Check | How it is done |
|---|---|
| Positional accuracy | Project locations are checked against documents; geocoding precision is recorded for each point |
| Common projection | All layers are reprojected to a common equal-area grid before overlay |
| Disclosure review | Published 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.
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.

Across the six pillars, led by Nexus Consortium
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.

The exposure, loss, scenario and capital views a risk officer, supervisor or ministry of finance would ask for, with the frameworks they report against. Structures follow supervisory and actuarial practice. Values are illustrative: never prices, ratings or advice.
