B.3Regional reading, Italy by macro-region
Map plates for each region follow in Q2 2027. This page gives the regional reading in table form, and ranks no region.
| Area | Principal hazards | Systems most exposed | Baseline evidence |
|---|---|---|---|
| North-west | floods, landslides, Alpine change | cities, industry, hydro | 1126 |
| Po valley and Emilia-Romagna | drought, floods, heat | agriculture, water, health | 1424 |
| North-east and the Alps | glacier loss, storms, landslides | hydro, forests, tourism | 26 |
| Central Italy | earthquakes, landslides, heat | buildings, cultural heritage | 15 |
| Lazio and Rome | heat, flash floods | health, cities | 4 |
| Campania and the Campi Flegrei | volcanic unrest, earthquakes, landslides | dense settlement, health | 16 |
| Apulia and Basilicata | drought, Xylella, heat | agriculture, water | 19 |
| Calabria and Sicily | wildfire, earthquakes, drought | forests, water, agriculture | 20 |
| Sardinia | wildfire, drought | forests, agriculture | 20 |
The leading compound pathway runs through the Po basin and Romagna, where 2022 drought was followed by the 2023 floods.
PO BASIN
Drought, then flood
Ground uplift and earthquakes beneath a densely populated area make readiness the central question.
CAMPI FLEGREI
A volcano under a city
Drought, wildfire and Xylella combine in Apulia, Sicily, Calabria and Sardinia.
THE SOUTH
Water, fire and olives
B.4Atlas card, the Po basin and Romagna
- river basin
- irrigation district
- floodplain
- region
- Systems in view
- water, food, energy, health, infrastructure
- Defining events
- record low Po flows in summer 202224; May 2023 floods in Emilia-Romagna, 17 deaths, about €8.5 billion14
- Couplings
- WAT → FOO irrigation; WAT → ENE hydro; CLI → INF floods on dried soils
- Capability evidence
- water-severity observatory and regional civil protection used in real events
- Gaps
- storage and allocation in drought; exposure of homes and lifelines

- A-01 · A-02 · A-03
The Po basin carries much of Italy’s farm output; in 2022 its flows fell to the lowest in about seventy years [24].
DROUGHT
The river that feeds a third of the harvest
In May 2023 two storms in two weeks broke riverbanks and triggered hundreds of landslides in Romagna [14].
FLOOD
Rain on hardened soils
With few homes insured, reconstruction relied on public funds and emergency decrees [13].
RECOVERY
Public funds carry the load
B.5Italy system card
The card through which Italy appears in the Europe regional edition and the global series. It summarises; it does not rank.
| System | Baseline state | Coupling to watch | Coverage |
|---|---|---|---|
| Water | network losses and drought on the Po | drought into food and energy | GOOD |
| Energy | 41.2% renewables in demand | hydro in dry years | GOOD |
| Food | leading EU producer | drought and Xylella | PARTIAL |
| Health | Europe’s highest heat-death count in 2022 | heat and care capacity | GOOD |
| Biodiversity | rich, under wildfire and pest pressure | fire and land use | PARTIAL |
The Italy card sits beside its neighbours; Alpine water, electricity trade and Mediterranean hazards are read as one regional system.
EUROPE REGIONAL EDITION
One regional system
Italian 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 Italy is read against peer distributions and thresholds, never placed in a league table.
GLOBAL FLAGSHIP
Peers, not ranks
