3.2Domain posture
Each of the twelve coupled domains is read through Earth observation, in words, not scored. The coupling column names the dependency that carries Earth observation risk into each domain.
| Domain | Posture at baseline | Coupling | Status |
|---|---|---|---|
| WAT | Surface extent, snow, ice, rainfall and ocean heat are tracked from space; glacier loss in 2024 to 2025 was among the five most negative on record3. Water use volumes are not bound here. | EO → WAT | Reported EQL 4 |
| ENE | Observation networks and ground segments need reliable power; no consolidated series is bound here. | ENE → EO | Expert input EQL 2 |
| FOO | Monthly consensus crop condition reports for countries at risk of food insecurity have run since 2016 and reached a 100th issue in December 202421. | EO → FOO | Reported EQL 4 |
| HLT | 119 countries report multi-hazard early warning; heat caused an average of 546,000 deaths a year in the Lancet Countdown series234. | EO → HLT | Reported EQL 4 |
| BIO | Forest change is mapped at 30 m from Landsat; 2.3 million km2 lost and 0.8 million km2 gained in 2000 to 201232; tropical primary forest loss fell 36% in 20255. | EO → BIO | Reported EQL 5 |
| CLI | 2025 was 1.43 °C above 1850 to 1900 on WMO’s basis and 1.47 °C on the Copernicus basis; sea level 4.75 mm a year34. | EO → CLI | Reported EQL 5 |
| INF | About 54,000 objects larger than 10 cm are in orbit; 1,200 intact objects re-entered in 2025; ground stations and data hubs carry the system1. | INF ↔ EO | Reported EQL 4 |
| FIN | EUR 3.4 billion subscribed to the ESA Earth Observation Programme; institutional space budgets EUR 106 billion in 2023724. | FIN → EO | Reported EQL 4 |
| DAT | Nearly 80 PB online at one European service; 145 million Landsat downloads; a unified data policy adopted at WMO in 202191018. | EO ↔ DAT | Reported EQL 4 |
| AIC | Data-driven forecasts operational at ECMWF since 25 February 2025; foundation models trained on Landsat and Sentinel-2 archives2630. | EO ↔ AIC | Reported EQL 4 |
| MIN | Satellite and ground hardware depends on materials supply chains; no consolidated evidence is bound here. | MIN → EO | Expert input EQL 1 |
| TRD | Launch services, imagery and data cross borders; the EU Space Act proposal would set common rules for operators serving the Union25. | EO ↔ TRD | Inferred EQL 3 |
3.3Sector screens
All sixteen sectors are screened for their dependence on Earth observation, on the same grammar as every national edition. The evidence column describes coverage of the baseline evidence, not the performance of the sector.
| Code | Sector | Baseline evidence | Exposure to watch | Evidence coverage |
|---|---|---|---|---|
| GS-00 | Cross-system | Earth observation makes every system’s change visible32 | observation gap under extremes | PARTIAL |
| GS-01 | Water | surface water change mapped at 30 m33 | flood and low-flow monitoring | PARTIAL |
| GS-02 | Energy | networks and ground stations need power | loss of ground segment | THIN |
| GS-03 | Food and Agrifood Systems | monthly crop condition consensus reports21 | crop shock monitoring | PARTIAL |
| GS-04 | Health and One Health | 119 countries report early warning2 | heat and outbreak warning | PARTIAL |
| GS-05 | Finance and Economy | EUR 106 billion institutional space budgets24 | funding shift to defence | PARTIAL |
| GS-06 | Development and Humanitarian | small island developing States at 43%2 | warning gap in vulnerable settings | PARTIAL |
| GS-07 | Climate and Earth Systems | 1.43 °C above 1850 to 19003 | record continuity | GOOD |
| GS-08 | Disaster and Resilience | mortality six times lower with comprehensive systems2 | concurrent hazards | PARTIAL |
| GS-09 | Infrastructure, Transport and Logistics | ground stations, launch and data hubs1 | single points of failure | THIN |
| GS-10 | Cities and Urban Systems | heat exposure mapped from space34 | urban heat season | THIN |
| GS-11 | Biodiversity and Ecosystems | forest loss detected from satellite data56 | fire-driven loss | GOOD |
| GS-12 | Earth Observation and Planetary Intelligence | the sensing layer itself1012 | mission continuity | PARTIAL |
| GS-13 | Cyber and Digital Systems | ground segments and cloud archives9 | attack on a data hub | THIN |
| GS-14 | Policy, Institutions and Governance | unified data policy18; EU Space Act proposal25 | data and space rules | PARTIAL |
