This user manual supports the members of the German Roundtable on Marine Litter in using the internet platform https://muell-im-meer.de. In the internal area of the platform, members have various possibilities to present their organization and its activities for reducing marine litter as well as to participate in working groups. Distribution list maintenance and communication within the Roundtable on Marine Litter is also handled and documented via the platform.

Climate change is already causing an increase in extreme weather events, including an increase in the frequency and duration of periods of dry and drought conditions. In this paper, colleagues of the Emschergenossenschaft and Ecologic Institute summarize discussions on coordination and cooperation approaches for low water management and prevention at a workshop in the Emscher region.

Berlin is increasingly developing as a dynamic innovation field of the circular economy – a circular, resource-saving economy. (Social) innovations are no longer generated only in the field of waste recycling, but increasingly in the design and manufacture of sustainable products or with new business models. The event provided insights into current research on the development of the circular economy and the commitment of Berlin's innovators in this field.

Training the next generation of environmental lawyers is crucial for ensuring that environmental law is complied with and can thus serve its function of protecting the environment. Christiane Gerstetter, Senior Fellow at the Ecologic Institute, co-moderated an online course for German and Russian students entitled "Ecolaw and ecoactivism in Germany and Russia".
