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.
Farmer Federica Vidali looked anxiously at her sunflower field, where part of the field is already dry and starting to crack.
The 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.
Farmers are drawing heavily from the waterways to irrigate fields parched by the heat, but experts warn there's less than three weeks of water left in reserve.
Further downstream, seawater has pushed about 20 kilometres upstream, contaminating farmland and threatening fisheries.
Clam fishermen are also struggling with soaring June temperatures, which have warmed the lagoons and boosted the growth of algae that cover the shellfish.
