Xylella impact and crisis response in Salento
Overview
The Salento region in Puglia continues to face ecological and economic challenges due to the Xylella fastidiosa bacterium, which has destroyed over twenty million olive trees.
Scientific research published in Scientific Reports by the University of Salento and Argentina’s CONICET has quantified the environmental damage. Using satellite imagery from 2006 to 2022, researchers found that the loss of olive groves led to soil temperature increases of 2.4°C, whereas holm oak forests helped mitigate these rises to within 1°C. The study emphasizes that the groves previously served as vital carbon sinks and biodiversity stabilizers, prompting the development of reforestation scenarios for 2023 through 2032 to restore ecological balance.
In response to the ongoing crisis, local administrations are expanding efforts to secure official recognition for the region as a “disadvantaged area” or “agricultural crisis area.” While municipalities such as Mesagne, Torre Santa Susanna, and Villa Castelli initially led the push with support from Alpaa Puglia, the movement has grown. On October 8, 2026, the Unione dei Comuni del Nord Salento officially joined the mobilization, extending the effort from the province of Brindisi into the province of Lecce.
These local authorities are seeking extraordinary, multi-year support measures to address productive desertification, water shortages, soil salinization, and the socio-economic decline affecting small producers, cooperatives, olive oil mills, and rural workers.
