Two places. What can each learn?
Line up documented issues, causes, impacts and solutions. TerraLens does not rank places or produce an overall score — context differs, and so do the right answers.
Jakarta
Indonesia · 2 documented issues
A low-lying coastal capital affected by land subsidence from groundwater extraction, tidal and river flooding, and dense urban air pollution.
Rotterdam
Netherlands · 2 documented issues
A major European port city largely below sea level, internationally known for delta engineering, climate adaptation and port decarbonisation.
Categories
| Category | Jakarta | Rotterdam |
|---|---|---|
| Air | Severity: High | Not documented |
| Water | Severity: Critical | Not documented |
| Climate | Not documented | Severity: Moderate |
| Energy | Not documented | Severity: High |
“Not documented” means the atlas has no write-up for that category there — not that the place is free of it. Severity is descriptive editorial metadata summarising documented effects. It is not a measured index or a score.

- Intense rainfall and river discharge
Impacts
Jakarta
Land subsidence and flooding in Jakarta
- Increased flood frequency and depth
- Damage to buildings and infrastructure
- Saltwater intrusion

Learning across locations
Both places are dealing with flooding.
These documented approaches from one place address a shared category or theme in the other. Whether they transfer depends on local climate, governance, resources and the specific causes involved. Themes are matched from the wording of each issue.
floodingFrom Jakarta relevant to Rotterdam
Piped water expansion
Extending reliable piped supply so users no longer need private wells.

Groundwater extraction control
Licensing, metering and restriction of extraction, particularly for large commercial users.

Storm surge barriers and dikes
The Maeslant barrier and the national dike system close off or hold back extreme water levels.

Water plazas and green roofs
Public squares designed to hold stormwater temporarily, plus roof-level retention.
