In this way, the DKN provides a platform for,exchange on new scientific findings and research needs in the field of sustainability research and to foster,interdisciplinary collaborations within Future Earth and beyond. Future Earth is a network of scientists,,researchers and innovators designed to provide the knowledge needed to support transformations,towards sustainability. The focus of the summit was explicitly dedicated to national and international,interdisciplinary and integrative sustainability science, while discussing the previous and future work of,the DKN.,Around 500 participants from 46 countries from all over the world registered for the German,Sustainability Science Summit 2021. The conference was held as an online event on 8th and 9th July 2021,,with about 150 participants acting as hosts and speakers of the 29 different summit sessions.The summit,was preceded by an early-career researcher workshop on 7th July 2021 on opportunities and challenges,for early-career scientists in inter- and trans-disciplinary sustainability science.,One important item on the summit program was the discussion of the DKN position paper on central focus,topics and open research questions in sustainability research. The position paper was brought forward,by the DKN committee members, c oming from very different disciplines, and prior to the summit was,provided to all participants. The paper comprises the focus topics which were discussed during several,sessions of the summit, such as (1) Normativity in sustainability research, (2) Extreme events: collapse or,resilience? - the role of health, well-being and social cohesion for reaching the sustainable development,goals, (3) Diet, biodiversity and h ealth - the role of sustainable diets for healthy people and healthy,ecosystems, and (4) Scale challenges in climate change, risk and adaptation research in the context of,sustainable development. The lively discussions and interesting comments on the position paper will be,reflected in the future work of the DKN.,Most of the summit sessions were set up in response to an open call for session proposals. In addition to,the various scientific sessions and science-policy sessions with presentations and lively discussions, the,online conference platform enabled networking via v arious innovative tools including a poster and,networking session with a virtual art exhibition. The sessions covered a broad range of topics, including,climate change adaptation finance, the role of participation in just science and governance, water security,,biodiversity, planning and construction, systemic risks, and others. Also the three active DKN working,groups outlined their topics on (1) Modelling the human environmental interactions in the anthropocene,,(2) Antici pating and transforming coastal f utures, and (3) Sustainable, transformative and circu lar,bioeconomy.,The diverse program was rounded up with two vivid plenary panel discussions, shedding light on the new,social contract for climate change adaptation in dynamic societies and concluding the summit with,perspectives of international sustainability science.,The DKN thanks all panelists, speakers, presenters and participants for joining the summit, for all their,contributions and for participating in the enlightening and lively discussions. Many thanks also go to the,event agency Con Gressa for the technical realization of the event and for the creation of the summit,logo. And last but not least, strong thanks to the German Science Foun dation (DFG), without which the,summit would not have been possible.}, note = {Online available at: \url{} (DOI).
