Po drought exposes Italy's fragile water web

Italy's Po River has fallen to historically low levels as the country endures its fourth heatwave of the summer, exposing wide stretches of dry riverbed near Pavia and raising fresh concerns over water supplies and farming across northern Italy, according to Euronews.

The drought gripping the north is not an isolated phenomenon. It is the same weather system that has pushed temperatures toward 40C across the peninsula, with forecasters warning of a sweltering Ferragosto weekend, as The Local Italy reported.

For Basilicata, the Po's plight is a distant but instructive mirror. This southern region, like the Po valley, depends on irrigation for its agriculture — from wheat and olives to the vineyards that have made the area known abroad.

The Po River basin feeds nearly a third of Italy's agricultural production, and its low levels have prompted warnings about water rationing for farms and cities in the north. Euronews reported that the river has exposed dry riverbed near Pavia, a sign of the cumulative effect of successive heatwaves and scarce winter snowfall in the Alps.

In Basilicata, the stakes are comparable even if the scale differs. The region's agriculture relies on reservoirs and aquifers that have been under strain in recent dry summers. While the current crisis is centred on the Po, water managers across the south are watching the same weather patterns, aware that a prolonged drought would hit the region's crops and its livestock.

The heatwave that has driven the Po to historic lows is forecast to persist through the Ferragosto holiday weekend, with highs of 40C expected in parts of Italy, The Local Italy reported. That heat accelerates evaporation from reservoirs and increases demand for water just as the summer tourist season peaks along Basilicata's coasts.

The Italian government has not yet declared a national water emergency, according to the foreign press, but regional authorities in the north have begun discussing restrictions. For the deep South, the lesson of the Po is that water scarcity is no longer a northern or southern problem alone — it is a national one, and the regions most dependent on irrigation will feel it first.
