On June 18 and 19, 2026, the Blue Community Berlin, together with GRÜNE LIGA and its partner organizations, welcomed Australian legal scholar and Blue Community Ambassador Assoc. Prof. Dr. Erin O'Donnell to Berlin. As part of her European tour, she discussed river rights, water protection and new legal approaches to nature with representatives from academia, civil society and environmental organizations.
In addition to the public panel discussion and a film evening, the program also included visits to Berlin schools and an excursion to innovative water concepts.
In mid-June 2026, Blue Community Ambassador Erin O’Donnell, who is an Associate Professor at the University of Melbourne Law School in Australia and the author of "Legal Rights for Rivers: Competition, Collaboration and Water Governance", will be in Europe, delivering lectures in Zurich, Berlin and Vienna. The Blue Community Berlin welcomes her with a series of events on June 18 and 19 in Berlin.
In March 2024, the GRÜNE LIGA submitted a position paper to the European Commission as part of the Commission’s public consultation on the Nitrates Directive (91/676/EEC). The GRÜNE LIGA strongly advocates for the European Commission to uphold the Nitrates Directive. This crucial piece of legislation is needed to protect European citizens, farmers, and economies from the harmful effects of nitrate pollution.
The intensification of agriculture, driven by unsustainable use of fertilisers, has led to widespread nutrient pollution, affecting over 30% of surface waters, 14% of groundwater, and 80% of marine waters in the EU. Livestock production contributes to more than 80% of nitrogen emissions in groundwater, in particular through the excessive use of nitrogen-based fertilisers for feed.
The Nitrates Directive aims to protect water quality across the EU by reducing water pollution caused by nitrates from agricultural sources and promoting the use of good agricultural practices.
The importance of water for our life on Earth is undisputed. It nourishes us, cools us, rejuvenates us. In Berlin, the water supply system is currently in crisis. To draw attention to the urgent problems and to emphasize the need for binding solutions, our Water Policy Office, GRÜNE LIGA Berlin and the initiative "WasserZeichenBerlin" calls for a demonstration on the occasion of World Water Day on 22. March 2024.
Our demands:
1. consistent water retention and effective protection of our water bodies;
2. improved protection and enhancement of natural habitats in and around water bodies
3. binding measures against the drying out of small bodies of water and the lowering of the groundwater level;
4. community-oriented revitalization of urban water bodies and shoreline areas;
5. promotion of environmental education programs and campains;
6. introduction of innovative recycling methods for sustainable water use.
The route starts from the main train station along the banks of the River Spree to Lustgarten on Museum Island. The march will be accompanied by two boats. A mid-rally is planned at Friedrich-Ebert-Platz, very close to the memorial site "Weiße Kreuze."

The GRÜNE LIGA Federal Contact Point Water has been a member of the EEB's Water Working Group for over 20 years and is a founding member of both the Water Working Group of the Forum Environment and Development and the "Living Lakes Germany" network.
Michael Bender represents the GRÜNE LIGA as an observer at the International Commission for the Protection of the Elbe (IKSE).
In 2021, the cooperation between the GRÜNE LIGA and the Living Rivers Foundation was intensified and a joint office was established at the federal association.
Together with the GRÜNE LIGA Berlin, we were active in the Aktionsnetz Kleingewässer Berlin, in 2022.
Since January 2023, the GRÜNE LIGA Berlin e.V. is partner in the pilot project Wassernetz Berlin. We will organise 24 dialogues at water over 3 years (around 8 per year) to raise awareness of the public on the issues faced by water bodies and offer training in their management (biodiversity, physical and chemical status, etc.), as well as helping our partners in the project to prepare for the enhancement and restoration measures that will be implemented in the framework of this pilot project. You can find the schedule of dialogs on our events page.
On the European level, the GRÜNE LIGA e.V. is also member of the European Water Movement. The EWM aims at reinforcing the recognition of water as a commons and as a fundamental universal right.

On a global level, the GRÜNE LIGA e.V. is also involved in the People's Water Forum, a coordinating space for Water Justice Movements around the world.
