Coastal erosion and rising sea levels threaten Black Sea ecosystems

The Black Sea coastline is facing increasing pressure from coastal erosion and rising sea levels, driven by climate change and human activity. Recent observations across the region show that sections of the coast are retreating at a faster rate, putting both natural habitats and coastal communities at risk.
In areas of Romania and Ukraine, researchers have reported significant shoreline loss over the past decade. Stronger storms, higher wave energy, and gradual sea level rise are accelerating the erosion process. As coastlines shrink, critical habitats such as wetlands, dunes, and breeding areas for marine and bird species are being lost.
These ecosystems play an essential role. Wetlands act as natural filters, dunes protect inland areas from flooding, and coastal zones provide feeding and nesting grounds for a wide range of species. Their degradation weakens the resilience of the entire marine environment.
Human activity adds further pressure. Coastal construction, tourism infrastructure, and poorly planned development reduce the natural ability of coastlines to adapt. When combined with climate driven changes, this leads to faster and often irreversible damage.
The impact is not limited to nature. Coastal erosion also threatens local economies, particularly in regions that depend on tourism and fisheries. Damage to infrastructure and loss of land create long term economic challenges.
Addressing this issue requires a combination of policy, planning, and restoration. Protecting natural coastal barriers, limiting unsustainable development, and investing in ecosystem based solutions can help slow the process and reduce risk.
The Protection of Biodiversity in Bulgaria Foundation supports efforts to protect coastal ecosystems and raise awareness about the long term risks facing the Black Sea. Safeguarding these environments is essential for maintaining biodiversity and ensuring the stability of coastal regions.
