Dall’Aglio’s family has been investing in cooling systems for around 15 years, recently adding solar panels to help offset their growing electricity needs.
Across the Parmigiano Reggiano supply chain, such technology is becoming commonplace. Around half of its dairy farms, responsible for 70 percent of its milk, have invested in advanced cooling systems, including fans, motion-sensitive water sprays and automated temperature monitoring, according to the consortium president, Nicola Bertinelli.
The remaining 30 percent of milk comes largely from farms in the cooler hills and mountains, he said.
With persistently high temperatures, insufficient rainfall and water levels in major Alpine lakes approaching historic lows, authorities in the Po River basin, which supports agriculture across northern Italy through a network of tributaries and canals, have declared a high level of drought severity.
Alfalfa, an important source of forage for the cows, is relatively resistant to drought because of its deep roots. But Dall’Aglio said her family had already been irrigating heavily to ensure a good hay crop this year.
When rivers run too low for irrigation, some farmers have to pump groundwater instead, which can make irrigation around five times more expensive because of the energy required to extract it, according to Lorenzo Catellani of farmers’ association CIA Agricoltori Emilia-Romagna.
