Amalfi, Italy (CNN) — Above the green hills of the Amalfi Coast in southern Italy, an agile farmer leaps across terraced lemon groves overlooking the Mediterranean Sea.

Balancing between one wooden pole and another, the not-so-young acrobat defies gravity, bending to pick lemons and transport them in crates weighing more than 25 kilograms (55 pounds) between vertical gardens more than 400 meters (1,312 feet) above the ground.

A strong aroma of rosemary surrounds him, blended with jasmine, sage, and, of course, the unique bittersweet scent of citrus. The sound of waves below masks the hum of car traffic and noise from tourists in the main square of the UNESCO-protected town of Amalfi.

“Not blood, but lemon juice runs through my veins,” says 87-year-old farmer Gigino Aceto, whose family has been growing lemons here since the 1800s.

From dawn to dusk, Aceto’s life revolves all around lemons. He sleeps in his lemon groves and feeds on lemon food. He was even conceived among these plants.

“In my parents’ old days, the lack of space and intimacy meant that love was made outdoors, underneath the citrus trees,” he says with a smile.

The lemons are the beating heart of the area’s complex, biodiverse ecosystem, which has remained unchanged for centuries. But Aceto is among the last guardians of this vulnerable tradition now threatened by industrialization, changes in society and climate change.

The large Sfusato or Amalfi lemon is cultivated in an area that stretches along the Tyrrhenian Sea between Naples and the Gulf of Salerno. One single lemon can weigh up to three kilograms.
About 2,000 metric tonnes are currently harvested each year around the Amalfi Coast, according to local figures, but surveys show that these lemon grove areas have been in decline for the past 60 years.

“In Amalfi alone, lemon terraces have decreased from 72 hectares to 48 between 1954 and 2015, while wild forests and urbanization advanced considerably,” says Giorgia De Pasquale, an architect and researcher at Roma Tre University, who is looking for ways to preserve family lemon-growing businesses.
