This study shows that a commitment to a regional food policy promises positive effects in a whole range of policy areas, including environmental protection, sustainable land use, health, strengthening local value chains, education, and participation. Regional food policy in Germany requires the establishment of new structures and can only succeed if administrations work together across disciplines and sectors, if there is cooperation between the city and its environs and if it is shaped in a participatory process together with all the actors concerned. Due to the high media interest and the mobilisation potential that the topic of nutrition has to offer, it might be easier to set up these processes compared to many other topics.

This working paper identifies the main overarching trends affecting the food supply system, sets out the environmental and socio-economic implications of spatial decoupling of food production, consumption and disposal, and addresses the particular role of urbanisation in changing supply systems. The effects in industrialised and developing countries are considered in equal measure.

The German article "Seven at one blow! Regional Food Strategies as key to more sustainable Urban-Rural cooperations" deals with the role of regional food strategies as a promising approach for an integrated, sustainable development of urban and rural areas. The article, written by Stephanie Wunder, Coordinator Food Systems at the Ecologic Institute and Franziska Wolff, Head of Environmental Law & Governance at Öko-Institut summarizes the results of the UBA project "Rural Urban Nexus", led by Ecologic Institute. The text is part of "The Critical Agricultural Report". Since 1993 "Der kritische Agrarbericht" is an annually published flagship book, that critically reflects about agriculture in Germany in the context of the EU Common Agricultural Policy. The 2020 edition focused on the changing relationship between rural and urban areas.

The report "Integrated approaches for sustainable urban-rural development" published by the German Federal Environment Agency at the end of 2019 summarizes the results of the three-year research project "Rural Urban Nexus – Global Land Use and Urbanization" (RUN). The findings of the project, that was led by Ecologic Institute, show that there is already a wide range of strategic approaches, instruments and institutional forms for better collaboration between cities and their surrounding areas. Rather than establishing new instruments, administrations and policy makers should make greater use of existing possibilities – especially informal instruments of regional planning – and to integrate sustainable urban and peri-urban development into existing policies. In particular, the development of regional food strategies can be an important entry point and catalyst for achieving sustainable urban rural development.

The report first presents non-institutional factors that influence the relationship between urban and rural areas. In the second part, it provides an overview of institutional framework conditions and instruments for the design of sustainable urban-rural linkages. The third section of the report analyses existing instruments and policies for the sustainable design of urban-rural linkages. It covers instruments at the German, EU and international levels. Examples of good practice from European and non-European countries in the field of "regional food systems" have a complementary, illustrative function.

"More organic, more regional food, fit for the future – Transition of food systems through urban-rural cooperation" was the motto of this year's STADTLANDBIO Congress. Stephanie Wunder presented the policy recommendations of the research project "Rural Urban Nexus". She focused on the relevance of secure access to land for regional food producers.

The development of regional food strategies and cooperative approaches between urban and rural areas to reduce land take represent a suitable approach to the development of sustainable rural-urban linkages. Concrete policy recommendations can be found in the discussion paper of the Rural-Urban-Nexus project led by Ecologic Institute, which was discussed in the final workshop on 29 November 2018.

The workshop "Regional Food Systems and Sustainable Land Use in the Rural Urban Nexus" on 11 April 2018 discussed the potential that food systems can play to improve rural urban linkages. The workshop aimed to discuss the available insights at international level about success factors of regional food policies and if these are also relevant in the German context. To do so, the workshop brought together local policy makers, federal policy makers as well as participants from research and civil society. Stephanie Wunder, Senior Fellow at the Ecologic Institute and project leader of the Rural Urban Nexus project, presented success factors known from international examples and studies that promote rural urban linkages through regional food systems.

The project "Rural Urban Nexus – Global Land Use and Urbanisation" is developing approaches and policy recommendations directed at an integrated and sustainable rural and urban development.
