The Federation of Agricultural Cooperatives of Catalonia (FCAC) has expressed concern over the potential damage to key crops following the Dana passage. The storm is predicted to cause significant losses in citrus and olive crops in the Baix Ebre and Montsià regions, with clementines and certain orange varieties facing up to 40% loss in citrus crops and a 30% drop in olive crops. The intense october rains have led to fruit fall or rot, and high humidity and temperatures have allowed fungi to develop, threatening the marketability of the fruit. The FCAC emphasizes that some areas may see a 70% harvest decrease and quality issues due to fungi, with olive trees also suffering from olive fall and advanced fungal issues, exacerbating the previously expected 70% drop in production in Terres de l’Ebre, Catalonia's main oil-producing area.
