Research is ever deepening its knowledge in a multitude of fields. Such research contributes in great depth to identifying and understanding problems (e.g. in the field of climate change). However, when it comes to societal implementation, it may ultimately lead to zero knowledge at infinite depth, as it has been ironically put. To tackle sustainability, respectively to achieve the 17 sustainable development goals (SDGs) set by the UN, science has to come together and work in transdisciplinary teams. Scientists are poorly prepared for such an exercise and standard procedures of scientific work, sharing and publication of results in specialised conferences and journals do not help.In view of this problem, the Austrian Alliance of Sustainable Universities and research centres has created a project, UniNEtZ (Universities and Sustainable Development Goals), to jointly address the issues raised by the SDGs and develop suggestions for policies in a multidisciplinary approach. In order to facilitate this for the scientists involved, UniNEtZ is preparing collaborative measures and methods to address the issue of cooperation between disciplines to guarantee that all important interactions among SDGs are considered and addressed in equal detail. It is expected that changes in the way science and scientists are used to work together are necessary to achieve that. The developed concepts will be published in a handbook for UniNEtZ,In a next step, the  handbook also hints at the need for municipal, regional, and national administrations to transition towards a kind of governance, that enables implementation of policies towards the SDGs. Current hierarchically organised structures don’t seem ideal for the kind of transsectoral cooperation that will be needed to implement the expected measures.The contribution presents the findings of this work on cooperative research and governance structures.Keywords: SDGs, Sustainable Development Goals, transdisciplinary research, transsectoral implementation

The water, energy, and food security nexus (WEF Nexus) is the interlinkage between water security, energy security, and food security. An increasing world population is projected to increase energy and food requirements, which will increase the need for freshwater drastically in the coming decades. Projected climate change impacts will aggravate water availability, especially in urban areas. Nature-based solutions (NBS) have proven to generate multiple benefits that defuse the expected merging tensions within the WEF Nexus. This paper outlines the theories, provides examples, and discusses the potential of NBS to address the future WEF Nexus. For this purpose we reviewed recent papers on the theories of WE, WF, EF, and WEF Nexus, we described and summarized 19 representative real-life case studies, and we identified the knowledge gap within the theory and the case studies. We provide quantitative potentials and qualitative benefits for NBS described in the literature over the past decades. Our review demonstrated the impressive potential of NBS to address the projected challenges within the WEF Nexus. The study concludes by recommending NBS for specific WEF Nexus challenges and highlighting the need for decision-makers to consider the implementation of NBS in urban planings.
