Picture Italy’s famed coastlines – sun kissed sands stretching from the Amalfi Coast’s rough cliffs to Sardinia’s blue bays. These beaches? More than just pretty postcards; they prop up a tourism economy, supporting tons of lives. But, get this, a new report is saying paradise is in trouble. By 2050, Italy could lose almost a fifth of its beaches because of rising seas and erosion – a “bathing shock” that could really change the country’s shape, economy, and just, you know, life.
This concerning forecast comes from *”Sunken Landscapes”*, a big study out recently from the Italian Geographical Society (IGS). Using climate models, old data, and looking at geography, the report paints a bad picture of Italy’s 8,000-kilometer coast. If we don’t do something big, the study figures that 40 to 45 percent of Italy’s beaches could disappear by the end of the century, depending on emissions and how we try to adapt.
Causes of Italy’s Coast Crisis
At the core of this erosion issue is climate change, mainly rising sea levels. Warmer oceans grow, moving onto shores, and stronger storms bring floods and take away sand. “Italy’s coasts are super open to this because of their low land and lots of people living there,” the report says, pointing out that even small sea-level rises – like 0.3 to 1 meter by 2100 – could flood huge areas.
But nature isn’t the only problem. People are making it worse. Tourism, which makes over €200 billion each year, has put a lot of development on fragile coastal spots. Hotels, resorts, and boardwalks are crowding the water, messing up natural sand movement and making erosion worse.
“Too much tourist stuff creates a bad situation,” the IGS authors say. “It not only puts more pressure on beaches but also doesn’t leave room for nature to adapt.”
To top it off, defenses that were supposed to help are causing issues. Seawalls and barriers, built to protect beaches, often don’t work. By stopping sand from moving along the shore, these things make nearby areas lose sand, speeding up their end. “Short-term fixes are becoming long-term problems,” the report warns, pushing for less “hard engineering” and more nature-friendly solutions.
Hotspots of Hazard
Some shores are in worse shape than others, and the places are the ones people love to visit. The northern Adriatic coast, with its busy towns, is in big trouble, like the Gargano Peninsula in Puglia – a UNESCO spot known for caves and beaches.
Farther south, Tuscany’s Maremma beaches, Lazio’s volcanic shores near Rome, and Campania’s Gulf of Naples are really at risk. Sardinia, a pretty island, is also getting hit: big areas around Cagliari and Oristano could wash away, hurting the island’s tourism economy.
Even Italy’s wetlands – areas shaped by tides – are in danger. The Po Delta, with rivers and marshes full of birds, and Venice Lagoon show how risky it is. Here, rising waters don’t just take beaches; they blur the line between land and sea, covering old sites and nature spots.
A Cascade of Consequences
The issues from these “sunken landscapes” go way beyond losing beaches. Socially, the report thinks around 800,000 Italians – often in fishing towns – might have to move, causing displacement and loss of culture. “These aren’t just beaches; they’re homes and history,” stated the study.

The economic impact is, quite frankly, enormous, a researcher mentioned to reporters. Think of it: around half the port infrastructure in Italy, so crucial for trade and even fishing, is exposed. This potentially cripples logistical hubs, places like Genoa, Trieste, Bari. Then there’s agriculture, also facing an uncertain future. It is estimated that about 10 percent of farmland nationwide is at risk of salinization, basically rendering the soil unusable. The Po Delta, a place well known for producing a quarter of Europe’s arborio rice, is particularly at risk. The salty irrigation water? It could decimate harvests, which obviously has implications for food security and export income, the study points out.
And environmentally, it’s a similar story of cascading problems. Those barrier beaches, the ones that protect inland ecosystems from storms, they’re at risk of crumbling. This, in turn, endangers wetlands, dune systems, and marine nurseries. Hotspots of biodiversity, such as the flamingo flocks in the Po Delta or the seagrass meadows, are facing risks of extinction, which just amplifies Italy’s broader vulnerabilities related to climate change.
Paths to Preservation
Despite the rather gloomy picture, the IGS report doesn’t simply lament. Actually, it offers a course of action. The authors strongly suggest “renaturation” as a key part of recovery: essentially restoring mangroves, dune systems, and oyster reefs to act as natural defenses, as buffers that can absorb wave energy and trap sediment. “Nature-based solutions,” they suggest, “can rebuild resilience in areas where concrete structures have proved inadequate,” referencing some fairly successful examples in places like the Netherlands and Louisiana.
Then there is strategic retreat, admittedly a tough but probably unavoidable step. This involves gradually reducing development in high-risk locations – maybe even buying back properties located along the beach and relocating infrastructure – which could allow ecosystems a bit more time to recover. Combined with tighter regulations regarding zoning to limit coastal development and providing incentives to promote eco-tourism, this could potentially cut projected losses by as much as half.
The good news is that Italy isn’t starting completely from nothing. Initiatives such as the European Union’s Green Deal, along with funds like the PNRR (National Recovery and Resilience Plan), provide substantial resources for adapting to changing coastlines. However, the report emphasizes that time is perhaps the most precious thing they have. The authors conclude that “decisive, coordinated efforts taken now have the potential to protect Italian coastlines for future generations.”
As Italy deals with these dramatic shifts, the entire world is watching closely. Considering that coastlines everywhere are facing similar threats – from the sinking suburbs in Miami to the disappearing deltas of Bangladesh – “Sunken Landscapes” is, in many ways, a wake-up call. Will Italy show the way forward in how to coexist with the sea, or instead end up a cautionary example? The tides, alas, wait for no one.
