The biodiversity and climate crises are increasingly threatening planetary biodiversity and dependent livelihoods. Linkages between these two crises are already recognised by science and policy, but they are still not sufficiently addressed in integrated manner in practice. Nature-based solutions (NBS) and ecosystem-based approaches have the potential to enhance these synergies and deliver multiple benefits for ecosystems, biodiversity, climate change mitigation and adaptation, human well-being among other objectives. This topic was explored during the "International workshop on strengthening synergies for biodiversity and climate in multifunctional landscapes", organized by the German Federal Agency for Nature Conservation (BfN). Sandra Naumann, Senior Fellow at the Ecologic Institute, was a keynote speaker, presenting on the potential but also limitations of NBS to achieve climate and biodiversity goals.

On 4 July 2022, McKenna Davis from the Ecologic Institute spoke to the 2nd step of this methodology: EXPLORING existing urban greening policies, plans and regulations to identify gaps and understand local needs. Representing the CLEVER Cities project, she provided insights on how to ensure coherent and coordinated policymaking and align objectives across sectors and policies. She also highlighted relevant EU policies and initiatives supporting nature-based solutions to contextualise local action towards NBS mainstreaming.

On 22 June 2022, experts from various disciplines exchanged views on the transformation of the food system towards a more plant-based diet. More than 400 interested participants attended the event, which is part of the National Dialogue on Sustainable Food Systems in the context of the UN Food Systems Summit.

On 19 January 2022, Dr. Stephan Sina, Senior Fellow of Ecologic Institute, participated as an expert in a hearing of the Committee for Environment, Agriculture, Nature and Consumer Protection of the North Rhine-Westphalian Parliament on the motion of the parliamentary group BÜNDNIS 90/DIE GRÜNEN "Bekämpfung von Umweltkriminalität in NRW endlich stärken – Schwerpunktstaatsanwaltschaft und Koordinierungsstelle für NRW einrichten" (Drucks. 17/14258). Together with three other experts and the working group of the municipal umbrella organizations of North Rhine-Westphalia, he commented on the motion and answered questions from members of parliament.

What kind of Europe do we want for the year 2035? This question is addressed by the EU initiative 'Conference on the Future of Europe', which enables European citizens to discuss their own ideas for Europe's future. Within the member states respective National Citizens' Panels, participants developed policy recommendations that were later passed on to the Conference. Ecologic Institute's Matthias Duwe gave a presentation on the topic of Climate and Environment at the Citizens' Forum in Germany on 15 January 2022.

The climate crisis is impacting cities and communities across the globe. As extreme weather events become increasingly frequent, cities must work together to find effective nature-based solutions (NBS) to adapt to their changing climates. As lead partner in the BEGIN project, the Dutch city of Dodrecht welcomed cities, practitioners, researchers and citizens to join the conversation on the future of livable cities. To this end, the NEXT LEVEL 2021 conference was held as a hybrid event on the 20th of October 2021. Ecologic Institute's McKenna Davis was invited as an expert to present on NBS governance and policy.

Mandy Hinzmann, fellow researcher at the Ecologic Institute, gave a presentation in a scientific session of the World Resources Forum, which took place from 12 until 14 October 2021. She presented key policy options on how to foster the circular economy in the European textiles sector. She also participated in the discussion session after the presentations.

In this presentation, Ecologic Institute's International Climate Protection Fellow Mario Alejandro Delgado Galarraga reviews whether the evolution of Rights of Nature in America has influenced International Environmental Law, especially at a Regional level. It appraise and contrast national legal conducts with the Inter-American Court of Human Rights' Advisory Opinion "OC-23/17" (Environment and Human Rights). Thus, it centre on Comparative Law and International Environmental Law. The presentation was held during the IUCN World Conservation Congress 2021.

On 1 September 2021, Dr. Stephan Sina, Senior Fellow at Ecologic Institute, participated as an expert in a hearing of the Hessian State Parliament's Committee for Environment, Climate Protection, Agriculture and Consumer Protection on the draft of the SPD parliamentary group for a law to protect people and nature from climate change and its consequences. Together with twelve associations and experts, he commented on the draft law and answered questions from members of parliament. The written statement of Stephan Sina is published on the website of the Hessian State Parliament (Part 1, page 39 ff.) and is available here separately as a download.

Dr. Stephan Sina, Senior Fellow of Ecologic Institute, gave a keynote speech at the China-EU Conference on Climate Change Legislation on 29 June 2021. He presented the main features of the Climate Change Act (KSG) and its latest amendments based on the decision of the Federal Constitutional Court on 24 March 2021. He also participated in the discussion session after the presentations.

Climate change, biodiversity loss and ecosystem degradation are linked and interdependent challenges needing to be addressed in an integrated manner. Synergies can be enhanced by building on the multifunctionality and multiple benefits of biodiversity and healthy ecosystems, captured under Nature-based Solutions (NbS). These topics were explored in the session "Nature as a solution: For resilience, mitigation and sustainable development" during the 5th European Climate Change Adaptation Conference (ECCA2021). Ecologic Institute's McKenna Davis was a keynote speaker, presenting on the EU and global environmental policy landscapes and their role as a help or hindrance to NbS uptake.

The 2021 annual conference of German Association of Dietitians has put a focus on sustainability and its relevance for the work for dietitians as well as policy makers. Stephanie Wunder gave a impulse presentation on this topic entitled "Effectively using synergies between health-promoting and environmentally friendly nutrition".

The Urban Agenda for the EU recognizes the importance of nature-based solutions as tools for sustainable recovery and development. Yet implementation and mainstreaming at city level remain limited. Can the European Green Deal support these efforts? What role can European research projects play? To answer these questions, McKenna Davis was invited as an expert to contribute to the European Urban Knowledge Network’s (EUKN) Policy Lab on 'The Urban Agenda for the EU, its 'green' actions and the European Green Deal'. The 18 March 2021 event aimed to unravel the 'green' actions of the Urban Agenda for the EU and develop concrete messages for the ministers under Slovenia's Presidency on how to support cities dealing with regulatory obstacles when trying to reach environmental goals.

Invited by the Indian Centre for Science and Environment (CSE), McKenna Davis (Ecologic Institute) joined the "International Knowledge Conclave on Green Infrastructure" and presented on 'Policy instruments to promote urban nature-based solutions in Europe'. She focused on the range of policy, planning and financial instruments relevant for nature-based solution design, implementation and maintenance within a European context. Her presentation slides and a guidance document she co-authored are available for download.

Doris Knoblauch gave a presentation on plastic waste at the Freudberg School in Berlin on 9 December 2020. The lecture took place as part of the "Plastic Pirates" project.
