Farmers Fear Drought as Italy's Longest River Runs Dry
Farmers and fishermen face worsening losses as river flow drops below 300 cubic meters per second, according to the Italian irrigation agency.
Seawater has pushed about 20 kilometres upstream into Italy's longest river, the Po River, as the waterway dries during a heatwave, threatening the farming heartland that produces milk for Parmesan cheese.
According to Aipo, the Po River's flow has collapsed to below 300 cubic metres per second, far below the June average of around 1,500, a decline Stefano Calderoni of the Italian irrigation association says is unprecedented.
In Scardovari, Paolo Mancin, head of the local fishermen's cooperative, reports water temperatures reached 31 deg C, causing macroalgae to form and high clam mortality as farmers struggle with invasive blue crabs from North America.
Saltwater is contaminating farmland reclaimed over five centuries, forcing farmers to shut irrigation canals to protect crops, though barriers placed in the river only function when water flow remains sufficiently strong.
Damiano Di Simine, an expert with environmental group Legambiente, warns there is less than three weeks of water in reserve, while engineer Rodolfo Laurenti notes proposed dams may never be sufficient.
