Beehives on a farm in the Agri Valley. Although the pollution caused by oil production affects only a small part of the Agri Valley, it affects agriculture throughout the valley. Who wants to buy products from an area that you think is totally contaminated? Even if only part of the valley is contaminated, the distant customers do not know that. That had devastating consequences. In the last 20 years, the share of agriculture in the gross national product of Basilicata has plummeted by 50%.
Bees once had cultic significance in Matera and the surrounding area. In many rock churches you can still see the beehives hewn from the stone of the hermits, and Saint Ambrose, patron saint of beekeepers, can be found on many frescoes on the cave walls. Today beekeepers have sales problems outside Basilicata.
