Greek valley that became a lake stirs drought debate

Gracefully rising above a din of croaking frogs as the sun sets, a pelican flies over Lake Karla, one the largest inland expanses of water in Greece.

Drained in 1962 to combat malaria and restored again from valley to wetland in 2018 to remedy drought, the lake is now triple its normal size after deadly floods last year.

How to deal with the aftermath of the disaster has morphed into a debate about the future of farming in the Thessaly region as a whole.

The farmers around Karla — many the descendants of lake people who had transitioned to land only two generations earlier — saw their holdings and flocks decimated by last year’s floods.

“A great field stood here,” said Yiannis Tsiantos, the son of a fisherman and one of the few people in the lakeside village of Kanalia who still own a boat.

“We used to ride tractors here to collect almonds,” the 57-year-old said, steering his boat past half-sunken animal pens and groves. “Now it’s under water.”

Riding along is his friend Apostolos Polymerou, a 32-year-old sheep farmer.

“This used to be pastureland for four to five thousand cattle,” he recalled.

In September, Storm Daniel, a Mediterranean cyclone of unprecedented intensity, unleashed months’ worth of rain in just hours on Thessaly, Greece’s most fertile plain.

The deluge, which left 17 people dead, destroyed roads and bridges and drowned tens of thousands of farm animals.

‘Worst floods’ in history

Daniel, which arrived on the heels of a major wildfire wave, was followed just weeks later by Storm Elias.

Combined, they triggered what Prime Minister Kyriakos Mitsotakis later called “the worst floods” in Greek history.

Polymerou’s sheep are still traumatised by nearly drowning last year, and being cooped up in their pens for six months caused them further stress.

“They develop deformities in their lungs and liver. Had we known where this would end up, it would have been better to let them drown,” he said.

The lakeside village of Sotirio, once bordered by fields of corn and cotton, now lies at the edge of a swamp.

Dark green water buzzing with insects covers the fields. Even where the flood has receded, only silt and withered stems remain.

Angelos Yamalis, a third-generation farmer, said his family lost 50 hectares (120 acres) of cotton, 30 hectares of wheat and 15 hectares of pistachio trees.

“It was a complete disaster… Even after the water recedes, we don’t know if the fields will be productive,” the 25-year-old told AFP beside the swamp.

“We based our entire future on this area, on these crops,” Yamalis said, adding that new trees would need at least seven years to bear fruit.

Future of cotton

Greek authorities have not provided a timeframe for recovery and there are conflicting views on how to move forward.

Authorities in Thessaly favour digging a large canal that would let the water drain into the Aegean Sea.

But a Dutch water management company advising the Greek government advocates a different approach, aimed not just at stemming floods but also at preventing future drought.

The firm, HVA International, suggests building dozens of small dams that would contain rainwater in the mountains.

Thessaly also needs to rethink its reliance on cotton, Miltiadis Gkouzouris, CEO of the Amsterdam-based firm, told AFP.

The region needs to switch away from cotton production while there is still time to conserve what remains of its underground water reserves, he said.
