The Cinque Terre National Park is a summer holiday hotspot in Liguria known for its colourful houses, fishing harbours and steep cliffsides threaded through with hiking trails.

But a new analysis suggests its villages could be at serious risk of flooding within the next 125 years.

The study by an international team of researchers analysed two of the most exposed areas of the Cinque Terre coastline, which are home to the villages of Monterosso and Vernazza.

One of the key measures is the maintenance and preservation of stone walls, which are essential structures for hydrogeological stability especially in the face of increasingly frequent and violent weather events, as well as the conservation of the historic agricultural landscape.
