Plastikmüll ist ein zentrales Umweltproblem des 21. Jahrhunderts. Ein Großteil dieses Mülls stammt aus lediglich kurzzeitig genutzten Einwegverpackungen. Lebensmittelhersteller und Lebensmittelhandel stehen vor der Herausforderung, eine nachhaltige Gestaltung, Nutzung und Reduktion von Kunststoffverpackungen voranzutreiben. Drei Überlegungen sind hier zentral. Erstens muss der Einsatz von kurzlebigen Einwegverpackungen möglichst vermieden und reduziert werden. Zweitens müssen in den Bereichen, in denen Vermeidung nicht möglich oder ökologisch sinnvoll ist, Materialien nach Nachhaltigkeitskriterien (Ökobilanzen, toxikologische Tests) ausgewählt und Verpackungen dementsprechend gestaltet werden. Drittens müssen Unternehmen Ressourcen für betriebliche Innovation bereitstellen und Veränderungsprozesse möglichst transparent und partizipativ gestalten. Neben technischen Innovationen sollten soziale Innovationen und organisatorische Anpassungen im Mittelpunkt stehen. Dieser Policy Brief bietet eine wissenschaftlich fundierte Grundlage insbesondere für Unternehmen und Verbände in der Lebensmittelversorgung, aber auch für politische Entscheidungsträger*innen sowie Mitarbeitende in
Behörden, die sich diesen Erfordernissen stellen und damit als Pioniere der Nachhaltigkeit zu einer Lösung des Plastikmüllproblems beitragen wollen.

The Eastern Steppe of Mongolia is one of the world's largest mostly intact grassland ecosystems and is characterised by a close coupling of societal and natural processes. In this ecosystem, mobility is one of the key characteristics of wildlife and human societies alike. The current economic development of Mongolia is accompanied by extensive societal transformation and changes in nomadic lifestyles, which potentially affects the unique steppe ecosystem and its biodiversity. The changing lifestyles are mainly characterised by rural-urban migration, resulting in reduced mobility of herders and their livestock, and presumably affecting wildlife. The question is how mobility can be fostered under these transformation processes. Time is pressing as a new generation is born which is growing up in urban environments and with new skill sets but a potential loss of the tight connection to nature and the nomadic lifestyle.

Droughts threaten millions of people in Sub-Saharan Africa, leading to famines, water shortages, migration and casualties. Climate change will most probably exacerbate the devastating consequences as exceptional droughts are expected to occur more frequently. Conventional drought risk assessments however, do not provide adequate tools, as they often limit their focus to environmental parameters, ignoring social vulnerabilities. Integrated strategies are required to carry out holistic drought risk assessments that serve to find adapted technological and institutional solutions to ensure water and food security. This will contribute to the Sustainable Development Goals 1 “No Poverty”, 2 “Zero Hunger” and 6 “Clean Water and Sanitation”.

Despite various policy and management responses, biodiversity continues to decline worldwide. We must redouble our efforts to halt biodiversity loss. The current lack of policy action can be partly linked to an insufficient knowledge base regarding the conservation and sustainable use of biodiversity. Biodiversity research needs to incorporate both social and ecological factors to gain a deeper understanding of the interrelations between society and nature that affect biodiversity. A transdisciplinary research approach is crucial to fulfilling these requirements. It aims to produce new insights by integrating scientific and nonscientific knowledge. Several measures need to be taken to strengthen transdisciplinary social-ecological biodiversity research: Within the science community: firstly, scientists themselves must promote transdisciplinarity; secondly, the reward system for scientists must be brought into line with transdisciplinary research processes; and thirdly, academic training needs to advocate transdisciplinarity. As for research policies, research funding priorities need to be linked to large scale biodiversity policy frameworks, and funding for transdisciplinary social-ecological research on biodiversity must be increased significantly.

Um weltweit die Wasser- und die Sanitärversorgung zu sichern, muss zeitnah in großem Umfang in neue Trinkwasser- bzw. Abwassersysteme investiert werden. Nicht nur die Länder des globalen Südens stehen im Wassersektor vor erheblichen Herausforderungen, auch die meisten Industrieländer haben Nachholbedarf und massive Investitionserfordernisse. Angesichts des globalen Investitionsbedarfes ist mit einem rasant wachsenden Markt für Wasser- und Abwassertechnologien zu rechnen, der auch der deutschen Industrie gute Absatzchancen bietet. Die vorhandenen Stärken der deutschen Wasserwirtschaft auszubauen und deren Innovationsfähigkeit zu fördern, ist daher eine zentrale politische und gesellschaftliche Aufgabe. Dafür muss die derzeitige Forschungs- und Entwicklungsförderung intensiviert und neu justiert werden, wobei auf sehr guten Vorarbeiten aufgebaut werden kann.

Increasing bike traffic in many European countries is a sign of a shift in planning paradigms towards more sustainable mobility cultures. It is also the result of 20 to 30 years of evolution and refinement in the training of urban and transport planners. Capacity development is therefore key when it comes to changing mobility cultures. Nevertheless, the day-to-day work of transport planners still focuses mostly on motorised traffic and the tasks of creating a smooth traffic flow, improving accessibility, and maintaining infrastructure. Cycling plays only a minor role, with efforts often still concentrated on the building of cycle lanes. The broader strategic goal of how to make urban mobility culture more sustainable – and within this the need to focus on cycling as an everyday mode of transport – is often neglected. Direct regulation is not possible when it comes to mobility cultures. Instead they represent a community-wide (communication) process that calls for a new planning paradigm: Besides the political will to establish a sustainable urban mobility culture, emphasis must also be placed on skills and training for urban and transport planners.

Debates about climate-induced migratory movements – and their possible links to instability and conflict – along with the discussion on migration flows across the Mediterranean Sea frequently highlight the West African Sahel as a region of concern. However, findings from recent empirical research on Sahelian regions in Mali and Senegal suggest no evidence for increasing population movements towards Europe as a direct result of environmental stress and climate change. It is the patterns of migration that are changing and not so much the volume. A closer look at the social-ecological conditions of migration in the Sahel allows for an alternative characterization of the problem dynamics. It reveals a rich and comprehensive picture of mobility and the importance of climate and environment in this respect, and identifies starting points for policy options.

Rain- and floodwater harvesting (RFWH) technologies and water reuse are ideal and generalpurpose technologies to improve water security and to contribute to climate adaptation – in particular for semi-arid regions. These technologies are part of a multi-resources mix within an integrated water resources management (IWRM). They create capacities to buffer water fluctuations and alleviate water scarcity. In this way, they reduce the pressure on existing resources, and can stimulate local economies. However, in order to be sustainable, these technologies need to be adapted to the local context – through suitable design, adapted operation requirements, and a back-up by training users and operators accordingly.
