Bringing life to the Oder River, from the source to the sea

CCB • July 31, 2023

In the coming days, July 31st-August 4th, 2023, various river stakeholders (academic staff, water-related institutions, municipalities and government representatives, locals, NGOs, business owners, individuals) from 11 European countries will visit the Oder Delta during the 4th edition of the international River University (1), organised by Coalition Clean Baltic (CCB) in collaboration with Rewilding Oder Delta (ROD).

Taking the Oder River as an example and focusing on water pollution and risk management, they will explore the impact of the river's condition on the Baltic Sea, as well as climate change's consequences on the waters in the region.

The need for recovery

In 2022, the Oder, the transboundary river of Poland, Germany and Czech Republic, having one of the extraordinary European deltas, experienced the worst scenario of environmental catastrophe on Europe's scale, caused by anthropogenic pollution (2). To this day, the Oder River still registers a high level of salinity and conductivity. Saline discharges are an ongoing threat, and the toxic “golden algae” Prymnesium parvum are still present in the waters, with fish kills at specific points observed. These issues represent significant challenges for a smooth recovery.


"The Oder River recovery should be addressed holistically rather than in silos. We need a source-to-sea approach and awareness of the role that healthy rivers play in achieving a Good Environmental Status in the Baltic Sea. Sustainable use and protection are the only long-term, wise approaches to such riverine areas. It is a well-known fact that natural rivers have a greater self-cleaning capacity, offering many benefits to their users," - says Peter Torkler, Managing Director at Rewilding Oder Delta, and co-organiser of this year's River University edition.


Protection Plans for the Lower Oder River

The concept of a cross-border protected area of the Lower Oder River and its valley was made decades ago. Today, this initiative is still considered, needed and wanted, as it will benefit the river's health and the region's economy. Polish citizens of the Oder basin renewed these efforts with the initiative of Lower Odra Valley National Park (3). Already in the 1990s, a national park was established in the German part of this area. The need to create a coherent transboundary area of a protected Oder River valley should go from the old visionary papers to the bright new reality. The reality in which people not only use the rivers but also protect them, taking care of water security.


During the River University, participants will go on a canoe trip in the vicinity of an existing German national park and a planned Polish national park, in order to experience the ecological state of the river and discuss the topics of sustainable use and protection of natural resources and water safety.


Between rivers and the sea

On Thursday, the participants together with the staff of ZERUM educational centre in Ueckermünde will conduct water quality studies on the Szczecin Lagoon and Uecker River. Water samples and aquatic organisms will be examined from a boat and analysed directly on-site. The lagoon with its direct connection to the Oder River and Baltic Sea is sensitive habitat; fluctuations in salinity and high water temperatures have always made the lagoon susceptible to algal blooms. The expertise on the condition of the lagoon is crucial for preventing such events from happening as well as awareness raising on the importance of healthy and clean waters.


Connecting stakeholders and river practitioners

Initially founded in 2018 by Ewa Leś, this year's edition of the CCB River University is co-organised by Rewilding Oder Delta. The course will bring together various river stakeholders for five days of engaging indoor and outdoor workshops. The program includes presentations and hands-on activities led by top European academic staff and professionals. Among other sessions, the updated "International Warning and Alarm Plan for Oder Basin" (4) will be analysed due to its significance for the Oder Basin community regarding alarming procedures and communication. Can people feel safe and well-informed in case a similar disaster happens again?

The release and presentation of the new CCB research analysis, "The Greatest Water Management Challenges in the Baltic Sea Region" (5) is planned, aiming to support and foster positive changes in integrated sustainable water management in the Baltic Sea region countries.


"
There is a great need for up-to-date applied knowledge of river ecosystems and sustainable integrated water management practices. The River University delivers it in a practical and multi-sectoral manner while still being in contact with the river and its valley," - says Ewa Leś, River University founder and CCB Eutrophication Working Area Leader.

EU Council decision on 2026 fishing limits fails to implement legally required safeguards, jeopardising the fragile marine ecosystem
By CCB October 3, 2025
3 October 2025 - Coalition Clean Baltic, together with its Member Organization BUND - Friends of the Earth Germany and the citizens’ initiative “ Lebensraum Vorpommern ”, have launched a petition to stop new oil and gas drilling projects in the Baltic Sea . The petition comes in response to plans to exploit a deposit just 6 km offshore Świnoujście , Poland, in the transboundary waters of the Oder Estuary and Pomeranian Bay. The planned site lies at the heart of NATURA 2000 protected areas , which are vital for biodiversity, climate action, and local communities. Oil and gas extraction in the Baltic Sea poses severe threats to its fragile ecosystems. Industrial activities such as drilling, pipeline construction, and ship traffic risk polluting the water with chemicals, oil leaks, and toxic waste. Underwater noise from pile driving and increased traffic would further degrade marine habitats. These pressures add to the already critical challenges faced by the Baltic Sea, including biodiversity loss, eutrophication, and the accelerating impacts of climate change. The consequences extend far beyond nature. Local communities rely on a clean and healthy Baltic for tourism, fishing, and quality of life. Expanding fossil fuel infrastructure would also undermine Europe’s climate commitments and lock in carbon emissions for decades to come. The petition calls on the Ministry of Climate and Environment of Poland, the Helsinki Commission (HELCOM), the European Commission, and the Secretariat of the Espoo Convention to : Stop the plans for oil and gas extraction in the Oder Estuary and the Pomeranian Bay; Ban any new oil and gas extraction across the Baltic Sea; Ensure strong cross-border cooperation and communication amongst all involved states. The petition is open through the WeMove Europe´s platform and can be signed here .
