Italy's drought-hit farmers face sea water threat

SCARDOVARI, Italy, June 29 (Reuters) - The worst drought in 70 years has meant salt water from the Adriatic sea is flowing back into the sluggish Po, Italy's longest river, doing further damage to crops hit by an early summer heatwave.

The flow of sea water into the Po makes irrigation almost impossible in parts of Italy's agricultural heartland, as it risks burning the already parched crops.

Some four kilometres from where the Po meets the sea in the small village of Scardovari in northeast Italy, waves crash through the anti-salt barriers and push downstream.

"You can see what happens, salt water enters the water table. There are parts of the fields with no plants and others where they grow regularly," said Giancarlo Mantovani, director of a group called "Reclaiming the Po" that tries to protect the river.

"If there is no rain in the next 10 or 15 days, the crops that are not yet lost will be gone. At this stage, we are progressively losing the harvest," he added.

The Po runs for more than 650 km from west to east across the north of Italy, a region which accounts for around a third of the country's agricultural output.

The river is suffering the effects of a lack of winter snow compounded by a baking early summer. Large areas of sandbanks lie exposed on stretches of the river as the water levels drop and its flow slows, making it easier for sea water to encroach.

Not far from the Po delta, Federica Vidali, 29, walks through a dried out field of soy plants where she works as an agricultural entrepreneur.

"Without rain, the water flow of the Po has dropped considerably and so it's not enough to counteract the rising sea water in the river. This means that in our (irrigation) channels we have salt water that is not suitable for irrigation," she said.

Vidali is also a beekeeper and the drought is also damaging honey production, because it means alfalfa and soybean flowers have no nectar for the bees to feed on... Read More
