Although it is one of the most important river ecosystems in this part of Europe, the Una River still lacks adequate protection. Significant parts of its middle course in Bosnia and Herzegovina, as well as a smaller section flowing through Croatia, remain unprotected, increasing pressure on the entire Una basin. If the initiative to establish a cross-border national park is accepted, the situation could change.

Around 60 representatives of public institutions, academia, environmental organisations, and citizens gathered today in Konjic for an expert symposium titled “Neretva - One Year Since the Fish Kill: What Were the Causes and How to Prevent a New Disaster?” 

Following seven days of intensive fieldwork, an international team of over 70 scientists and students has officially concluded Una Science Week.

More river kilometres have been saved! The Ministry of Spatial Planning, Construction, and Ecology of Republika Srpska has officially rejected the Environmental Impact Study for the proposed Nevačka small hydropower plant in the Bosna Basin in Bosnia and Herzegovina. 

A coalition of international and Bosnian scientists, together with leading environmental NGOs, reveal evidence linking the mass mortality of fish and other aquatic life on the affected stretch of the upper Neretva on September 12, 2025, to operational practices at the Ulog Hydropower Plant.

A recent study conducted by researchers from Austria’s Boku University provides crucial insights into the status and conservation needs of Danube salmon, or huchen, populations within Bosnia’s Upper Drina Basin. 

New threats to the Sutjeska and Jabušnica rivers are emerging, as construction of a new hydropower plant threatens the ecosystem of Sutjeska National Park. Concerns over outdated permits and environmental impacts have sparked protests urging authorities to halt these destructive activities. Join the fight!

Neretva Science Week 2023 took place from May 30th to June 7th. A diverse team of 62 scientists from 17 countries gathered in small town Ulog, to contribute to the conservation of the Neretva river system. Here, we gathered the preliminary results of Neretva Science Week 2023, covering 19 studies or fields of expertise. READ MORE

On November 11th, 2,000 nature enthusiasts and nine NGOs from across Bosnia-Herzegovina gathered in Konjic. United with slogans like "Neretva has its defenders" and "Let’s Save Neretva," they voiced their demands for authorities to halt hydropower projects in the Neretva basin, particularly the
