Sustainability science aims not only to understand pressing challenges but also to generate positive effects that drive sustainable transitions. However, little is known regarding how well this field achieves the latter goal. To address this gap, we explore the sustainability effects of research projects that have been conducted over 20 years in five biosphere reserves (BRs). Document analysis and expert interviews with BR man...

Transitions to more sustainable food systems are urgently needed, but they are also very complex and hard to achieve. The integration of transdisciplinary approaches into transition research can help to understand and promote sustainable food system transitions, but remains an agenda item in this research field. To fill this gap, this article describes how the multi-level perspective (MLP) can be used as a framework for explor...

Urbanization processes are accompanied by growing global challenges for food systems. Urban actors are increasingly striving to address these challenges through a focus on sustainable diets. However, transforming food systems towards more sustainable diets is challenging and it is unclear what the local scope of action might be. Co-production of knowledge between science and non-science is particularly useful for analysing con...
