B.3Regional reading, the Länder by region
Map plates for each Land follow in Q2 2027. This page gives the regional reading in table form, and ranks no Land.
| Region | Principal hazards | Systems most exposed | Baseline evidence |
|---|---|---|---|
| Rhineland-Palatinate and Saarland | flash floods, heat | valley towns, transport | 2021 floods14 |
| North Rhine-Westphalia | flash floods, low Rhine water | industry, freight, housing | 1424 |
| Baden-Württemberg | heavy rain, heat, low water | industry, cities | 824 |
| Bavaria | river floods, heat, Alpine change | cities, agriculture | 8 |
| Hesse | heat, heavy rain | cities, data centres | 8 |
| Lower Saxony and Bremen | storm surge, drought | coasts, agriculture | 9 |
| Schleswig-Holstein and Hamburg | storm surge, sea-level rise | ports, coasts | 9 |
| Berlin and Brandenburg | drought, heat, forest fires | water supply, forests, health | 420 |
| Saxony, Saxony-Anhalt and Thuringia | river floods, drought, heat | forests, agriculture | 20 |
| Mecklenburg-Western Pomerania | drought, storm surge | agriculture, coasts | 9 |
The leading compound pathway runs along the Rhine, where low water meets the industrial heartland.
RHINE CORRIDOR
Freight and industry
Small, steep catchments in the west hold the 2021 reference case.
UPLAND VALLEYS
Flash floods
Brandenburg and Saxony carry dry sandy soils, pine forests and growing fire risk.
EAST
Drought, fire and forests
B.4Atlas card, the Ahr valley and the Rhine corridor
- catchment
- waterway
- industrial corridor
- district
- Systems in view
- water, infrastructure, industry, health
- Defining events
- July 2021 Ahr flood, 135 deaths14; low Rhine water in 2018 and 202224
- Couplings
- CLI → WAT → INF flash floods; WAT → TRD low water; TRD → industry inputs
- Capability evidence
- reconstruction after 2021; part-loading and diversion in low water
- Gaps
- warning reach in small catchments; freight alternatives
- Agenda items
- A-01 · A-02 · A-03
The Ahr rose faster than warnings could travel; most deaths occurred at night in the lower valley [14].
FLOOD
Hours, not days
Chemical and steel plants along the Rhine rely on barges for bulk inputs; low water cuts their supply [24].
FREIGHT
One river, many plants
With many homes uninsured, reconstruction rested on federal and Land funds [13] [14].
RECOVERY
Public funds carry the load
B.5Germany system card
The card through which Germany appears in the Europe regional edition and the global series. It summarises; it does not rank.
| System | Baseline state | Coupling to watch | Coverage |
|---|---|---|---|
| Water | flash floods and low Rhine water | freight and industry | GOOD |
| Energy | about 54% renewable power | flexibility after coal | GOOD |
| Food | major EU producer | drought | PARTIAL |
| Health | heat burden among older people | heat and care capacity | GOOD |
| Biodiversity | insects and forests declining | drought and pests | GOOD |
The Germany card sits beside its neighbours; the Rhine, electricity trade and supply chains are read as one regional system.
EUROPE REGIONAL EDITION
One regional system
German evidence enters the water, energy, food, finance and climate sector reports through the same finding identifiers.
GLOBAL SECTOR SERIES
Same findings, same IDs
In the global edition Germany is read against peer distributions and thresholds, never placed in a league table.
GLOBAL FLAGSHIP
Peers, not ranks
