The association said the long period of intense heat and lack of rain has badly hit both crops and livestock.
At least 10 Italian regions are preparing requests to the agriculture ministry for a state of natural calamity to be declared because of the drought, ANSA news agency quotes sources as saying.
In Rome, water utility company ACEA is considering rationing water for around 1.5 million people after authorities in the Lazio region ordered an end to pumping water out of the nearby Lake Bracciano.
The lake’s water level has fallen significantly due to the recent drought.
The move could kick in next weekend, with water being cut off for around eight hours, mostly in the night and in the morning.
A meeting will be held at the environment ministry in Rome on Wednesday or Thursday in an attempt to avert the possibility of water rationing in the capital due to the drought.
Environment Minister Gian Luca Galletti and officials from the Lazio region and ACEA are set to be among those taking part, sources said.
