  • Sparse: 500 people/km² within 1 km · WorldPop 2026
  • Outside the modelled 1-in-100-year river/coastal flood extent; 0% intermittent surface water within 250 m; local elevation comparison unavailable.
  • 100% of land within 500 m is green (tree cover 99%).
  • 2050 outlook (high-emissions scenario): none in the model in a 1-in-100-year flood (today: none in the model). Scenario, not a forecast.
  • Water stress: High (40–80%) (baseline); projected High (40–80%) by 2050 (business as usual). WRI Aqueduct 4.0; catchment-level.
