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

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.

Energyabout 54% renewable powerflexibility after coalGOOD

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
