Farmers fear drought as Italy's longest river runs dry

Seawater is seeping into Italy’s longest river as the waterway starts to run dry in the heatwave, hitting a farming heartland that produces the milk for Parmesan cheese. The Po River has never fallen this low so early in the year, raising fears of a devastating drought in July in this corner of northern Italy. On the bank of one of its branches, farmer Federica Vidali looked anxiously at her sunflower field. The first bloom of the season has appeared, but part of the field is already dry and starting to crack.

But we’re not second-division farmers!” Vidali told AFP. The Po River’s flow has collapsed in a matter of days, dropping below 300 cubic meters per second, compared with an average of around 1,500 in June, according to the Interregional Agency for River Po (Aipo).

Sandbanks are multiplying, depths fall to barely one metre in places and the river’s few remaining fishermen swelter in the heat.

The many Alpine lakes that feed the Po Valley, Italy’s agro-industrial heartland, are still about 60 per cent full. But farmers are drawing heavily from the waterways to irrigate fields parched by the heat. It rained this winter, but the mountain snow that used to replenish the lake has already melted due to climate change.

Drought last struck the Po Valley in 2022 — but only at the end of July. ‘Really big problems’ Further downstream, at the river’s mouth, the situation is already serious: seawater has pushed about 20 kilometres upstream. Saltwater is beginning to contaminate farmland reclaimed over the past five centuries from the delta marshes. Barriers have been placed in the river to stop seawater, but they only work if the river’s flow is strong enough.

Laurenti called for cooperation and solidarity between regions to manage water in the event of a crisis. Farmers are also considering new dams or water retention basins, but “we’re afraid that all these structures will still never be enough,” Laurenti said. A few kilometres closer to the sea, clam fishermen are also struggling with soaring June temperatures. The heat has warmed the lagoons, boosting the growth of algae that cover the shellfish.
