• Living under threat of landslides: The Italian villages at risk of disappearing

Contesto

ROME – More than 500,000 buildings and nearly 38,000 churches, monuments, and historic sites across Italy are situated in areas exposed to landslides, according to official assessments, placing a vast swath of the nation's population and cultural heritage under a constant and growing threat. The country's unique geological profile, characterized by its mountains, hills, and fragile cliffs, renders it one of Europe's most susceptible nations to hydrogeological disasters, including sinkholes, severe erosion, and floods. This pervasive risk is now causing profound concern among local authorities from the Alpine north to the southern coasts, where entire villages face the prospect of gradual disappearance or sudden catastrophe. The scale of the vulnerability is staggering, encompassing not only residential homes but the very fabric of Italian history and identity. The nearly 38,000 cultural heritage sites at risk represent an irreplaceable chronicle of art, architecture, and community memory, from ancient Roman ruins and medieval hilltop villages to Renaissance churches and Baroque palazzos. This intertwining of modern habitation with ancient patrimony complicates both the practical and emotional calculus of mitigation and response, turning every potential landslide into a dual tragedy of displaced families and lost history. Experts point to a confluence of natural predisposition and human activity as the root causes of the accelerating crisis. Italy's tectonic youth and varied topography have always created instability, but decades of urbanization, deforestation, and intensive agriculture on marginal lands have significantly exacerbated the fragility of the terrain. Climate change acts as a potent force multiplier, with increasingly intense and erratic rainfall events overwhelming aged drainage systems, saturating slopes, and triggering ground failures in areas previously considered stable. The result is a national map increasingly dotted with red zones, where the ground itself can no longer be trusted. For the residents of countless small towns and villages perched on steep slopes, life is now measured in a tense awareness of the weather forecast and the slow,...
