Why one of Europe's wealthiest regions is choking on its own success — and what history tells us about the way out.
There is a stretch of land in northern Italy where civilisations have risen and fallen with the rhythms of a single, restless river. The Po Valley, cradled between the Alps to the north and the Apennines to the south, has been one of Europe's most consequential landscapes for over three millennia. It has nurtured Bronze Age glass artisans, Etruscan merchant princes, Venetian hydraulic engineers, and Fascist-era land reformers. Each generation faced the same fundamental challenge: how to master the water that gave the valley its extraordinary fertility, giving rise to highly productive agricuture, and innovative industries, while threatening to swallow its settlements whole.
Today, the Po Valley faces a new environmental crisis — not of water, but of air. The same bowl-shaped topography that once funnelled trade routes from the Baltic to the Mediterranean now traps atmospheric pollutants with devastating efficiency. Fine particulate matter regularly exceeds both European Union limits and World Health Organization guidelines, and the region endures some of the worst air quality on the continent. The question posed in this article is as simple as it is uncomfortable: if historical republics and authoritarian regimes alike could summon the political will to conquer water, why can't modern Europe conquer the air?
