Climate adaptation and climate protection are among the most important challenges of our time and have therefore become a major policy responsibility. The same applies to protecting biodiversity and ensuring the availability of water. Nature-based solutions (NBS) can play an essential role in addressing these challenges, as they are multifunctional and can generate high synergy effects. But what exactly are NBS, what do they have to do with climate adaptation, and can they be implemented? Sandra Naumann, Senior Fellow at Ecologic Institute, answered these questions in an interview with adelphi. The interview was published in the fifth issue of the Center for Climate Adaptation's Newsletter.

On 23 November 2022, 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 Government draft of a Hessian Act on the Promotion of Climate Protection and Adaptation to the Consequences of Climate Change. Together with about 40 associations and experts, he commented on the draft law and answered questions from members of parliament.

Diverse crop rotation, mechanical weed control, beneficial insects to protect crops: According to a study commissioned by BUND, standard practice in organic farming could also be used more often by conventional farmers. Aaron Scheid from the Ecologic Institute and author of the study in an interview with Deutschlandfunk radio about non chemical plant protection measures.

Leading institutes from the fields of sustainability and futures studies welcome the development of a "Future Strategy for Research and Innovation" by the Federal Ministry of Education and Research. At the same time, they point out that, while the presented draft provides significant momentum, it does not yet fully consider the societal challenges and the urgency to act.

Representatives from EU institutions and experts from 10 EU Member States discussed the Conference on the Future of Europe (CFE), and its impacts on EU climate and energy policies. Participants also discussed whether citizens' panels should become a standard feature of EU decision-making. The event concluded the project "The Future of the EU – Make Climate Action its Trademark", funded by the European Climate Initiative (EUKI).

This international conference provides an opportunity to learn and exchange knowledge on the topic of microplastics in soils, and is aimed at scientists and decision-makers alike. The first day of the event focuses on the state of the science, the second day on identifying policy solutions and recommendations for action at the European and international level. This hybrid event took place on 19 and 20 October 2022 in Berlin (Germany). Ecologic Institute organised the conference as a hybrid event, which was attended by 60 people on site and up to 150 people online.

Mandy Hinzmann and Doris Knoblauch (both Ecologic Institute) each accompanied a class in October 2022 with the Plastic Pirates, a Citizen Science campaign to collect data on (plastic) waste pollution in rivers. The students take on the role of scientists and collect, sort and catalogue litter according to scientific methods. The results are checked and incorporated into a large study.

In her presentation, titled "Evaluating environmental policies with citizen science data? An example from the Plastic Pirates investigating plastic pollution of rivers", Linda Mederake (Ecologic Institute) presented an approach to evaluate the Single-Use Plastics Directive with the help of citizen science data.

In an interview with "Bürger schaffen Wissen", the central platform for citizen science in Germany, Linda Mederake (Ecologic Institute) and Tim Kiessling (Kiel Science Factory) talk about the history of the citizen science project "Plastic Pirates", their experiences in working with school classes and their expectations for the ECSA Conference 2022.

The environmental disaster on the Oder River has brought the issue of environmental crime back into the spotlight. In a video report by the TV station Deutsche Welle, experts, including Stephan Sina from Ecologic Institute, explain the reasons for the difficulties in prosecuting environmental crimes and possible approaches for improvement. The contribution "Environmental Crime – How do they get away with it?" can be viewed online.

In an interview with Sinan Reçber of the Berlin daily Der Tagesspiegel, Rodrigo Vidaurre and Benedict Bueb of Ecologic Institute discussed what measures can be taken in various sectors to lessen the impact of droughts in Germany. In addition to water-sensitive urban development, which increasingly relies on nature-based solutions to store water during dry periods, this includes the cultivation of drought-resistant agricultural varieties as well as the rewetting of peatlands.

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.

Concrete and asphalt make cities up to 10 degrees hotter than the rural areas. In Poland, however, there is a persistent impression that greenspace is a nuisance that is best gotten rid of, says Ewa Iwaszuk of the Ecologic Institute in Berlin. She points out that the situation in Germany is better because nature has been considered an indispensable part of the city since the 1990s. She talks about innovative nature-based solutions that can mitigate climate change in cities and explains the introduction of blue-green infrastructure. Monika Sędzierska from the COSMO editorial office moderated the conversation.

Carbon farming refers to a range of agricultural techniques that increase the ability of the soil to sequester carbon from the atmosphere. This is crucial to achieving the European Green Deal goal of becoming CO₂-neutral by 2050. However, there are still many political and technical issues. Ecologic Institute's panel discussions included input on the report "Carbon farming. Making agriculture fit for 2030" and presented further thinking on carbon farming.

The two-day workshop, funded under the BMUV's Environmental Research Plan, took place on 30 and 31 May 2022 at the Federal Environment Agency in Dessau (Germany) and was dedicated to the topic of "Technical-Hydraulic Assessment of Fish Protection and Downstream Migration at Hydropower Plants".
