The webinar "Effective measures promoting biodiversity – implementation in practice" on 5 October 2023 takes a look at the implementation of concrete measures to promote biodiversity in the context of urban development funding. What challenges arise in the creation and maintenance and how can these be overcome?

At the practical forum "Climate Adaptation on the Ground", around 40 participants discussed political and legal options for promoting nature-based solutions for municipal climate adaptation in Germany.

The webinar "Considering biodiversity in urban development funding areas – insights and experiences" on 14 September 2023 will focus on how biodiversity can be considered in urban development funding areas. How, for example, can biodiversity, quality of life and climate adaptation be brought together in integrated urban development concepts and integrated into the overall concept?

In the webinar "Fit for the summer: How can nature-based solutions make municipalities more resilient?", the opportunities that nature-based solutions offer municipalities were discussed.

The first International Symposium of the NICHES project will combine presentations about international successful examples of nature-based solutions and provide a forum for discussion about current challenges and opportunities in the Metropolitan Area of Barcelona.

This webinar was jointly organised by the projects: INTERLACE, CONEXUS, REGREEN and CLEARING HOUSE as an official side-event of the European Week of Regions and Cities 2022. The webinar brought together about 500 representatives from cities, regions and local authorities, city network representatives, policy-makers, researcher, civil society and experts on nature-based solutions and urban ecosystem restoration from Europe, China and Latin America.

What might social-ecological data governance look like that preserves individual rights and freedoms, ensures participation, and contributes to sustainable urban development? Is the data generated by daily mobility behaviour private or public in nature? What does this mean for data sharing or for targeted and sustainable use of the data? What roles can so-called intermediaries like a data trustee play? In the eleventh edition of Wandelwecker, our morning feature for a social and ecological metropolis, we discussed these questions with two renowned experts.

On the 12 and 13 May 2022, the INTERLACE project held the first Latin American Cities Talk Nature Engagement Event in San José, Costa Rica. The project is led by Ecologic Institute.

Berlin has set ambitious standards for the prevention of CO2 emissions, with significantly stricter targets in the new Climate Protection Act (EWG Bln). What are the targets and opportunities, and what are still the major challenges and barriers? In order to become climate-neutral, it is imperative that the building sector be given greater consideration. The Climate Protection Act and the Berlin Energy and Climate Protection Program (BEK) 2030 emphasize the exemplary role of the public sector in this area. This means that public buildings such as school buildings are a key factor. In the districts' renovation roadmaps, schools sometimes account for more than 80 percent of the buildings that need to be renovated for energy efficiency in the next few years.

The more stringent climate targets of the state of Berlin require that both the heat supply is converted to renewable energies in the next few years and that the building envelopes are ambitiously renovated to make them more energy efficient. This poses great challenges for the state and districts as well as the real estate industry. At the same time, due to the tense situation on the Berlin housing market, there is a need for regulations to protect tenants, which is why the number of milieu protection areas in Berlin's districts has risen sharply. In these areas, which already contain a relevant proportion of old buildings which are in need of refurbishment, there are additional obstacles to climate protection measures that are in line with the objectives.

Nature-based solutions (NbS) are crucial for cities to jointly address the climate and biodiversity crises, while creating quality green jobs and wellbeing for local communities. This COP26 EU Side Event featured different sector practitioners (policy makers, entrepreneurs, international organizations) delivering inspiring presentations and engaging in a panel discussion highlighting a variety of perspectives on key challenges, opportunities, and pathways to mainstream urban NbS and boost local economies.

In the Ecornet Berlin research partnership, five Berlin institutes of transdisciplinary sustainability research were jointly providing impetus for Berlin's transformation. Their annual conference, "Knowledge. Change. Berlin. 2021" brought current research findings into dialogue with experiences from other cities and the voices of Berlin's practitioners and civil society – for a social and ecological capital.

In Berlin, a variety of initiatives show how the economy can be different: with more solidarity, more democracy, more ecological and better for all. We discuss why this is not easy, but can be promising. In the sixth edition of Wandelwecker, our morning impulse for a social and ecological metropolis, we discussed these questions with two experts.

On September 2021 at the online Future Forum, the research network Ecornet Berlin discuss the future of cities and their relationship to the surrounding areas with an expert panel

The Berlin Energy and Climate Protection Program 2030 gives solar energy a central role, as it is the most important renewable energy source that can be developed locally. The state government wants to cover 25 percent of Berlin's electricity supply from solar energy as quickly as possible. In the densely populated city, this also requires the roofs of apartment buildings to be used. In the discussion format Wandelwecker on 8 September 2021, Fabian Zuber from the Reiner Lemoine Foundation and Ecologic Institute's Katharina Umpfenbach discussed options transforming the regulation of tenant electricity and local solar power supply. The event was moderated by Valentin Tappeser from IÖW. It became clear that solar expansion can only be achieved at the required speed with a fundamentally new regulatory approach centered around joint self-supply that intelligently links on-site power generation via solar systems with charging of electric vehicles and heat generation.
