Across the stony heel of
Italy, a peninsula ringed by the blue-green waters of the Mediterranean,
olive trees have existed for centuries, shaping the landscape and
producing some of the nation’s finest olive oils. Except now many of the
trees are dying.
Sprinkled
among the healthy trees are clusters of sick ones, denuded of leaves
and standing like skeletons, their desiccated branches bereft of olives.
The trees are succumbing to a bacterial outbreak that is sweeping
across one of Italy’s most famous olive regions, as families that have
manufactured olive oil for generations now fear ruin, even as officials
in the rest of Europe fear a broader outbreak.
“It
is devastating,” said Enzo Manni, director of ACLI-Racale, an olive
cooperative in the heart of the outbreak area. “It is apocalyptic. I
compare it to an earthquake.”
Today,
scientists estimate that 1 million olive trees in the peninsula, known
as the Salento, are infected with the bacterium, Xylella fastidiosa, a
figure that could rise rapidly. The bacterium steadily restricts water
flow from the roots of a tree to its branches and leaves.
More details at the
StarTribune. The bacterium "is believed to have arrived with plants imported from Costa Rica and has
destroyed citrus trees in Brazil and vineyards in California."
