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.
