Andreas Blum is a sociologist and senior researcher at the Leibniz Institute of Ecological Urban and Regional Development (IOER). His research addresses societal developments and trends in sustainable construction and urban development, with a focus on social issues of resource consumption for the built environment. He is involved in the implementation and support of quantitative and qualitative surveying projects on different thematic issues. A recent project is the implementation of a nation-wide representative online survey of German cities and communities on building land and infill development capacities (https://www.ioer.de/en/projects/building-land-survey-2020). He was also substantially involved in a qualitative expert survey on the contribution of local environmental initiatives to an urban sustainability transition as a part of the EU-HORIZON-funded Project "Accelerating and Rescaling Transitions to Sustainability" (ARTS; http://acceleratingtransitions.eu/).

Dr Ir Inge Bobbink I am an associate professor at the section of Landscape Architecture since 2007, in the department of Urbanism at the Technical University Delft at the Faculty of Architecture and the Built Environment in the Netherlands. I hold a post-master degree from the Berlage Institute and obtained my PhD at Delft for the dissertation entitles "The Landscape Architecture of the Polder-boezem system, structure and form of the water network, water pattern and water work in the Dutch lowlands". In cooperation with others, I wrote, developed and since 2010 coordinate the educational program for the master track of Landscape Architecture. In addition, I teach and supervise master and PhD students, lecture internationally, and take part in the department's management team and different advisory boards. My research focuses on identifying landscape architectonic and sustainable values in (traditional) water systems worldwide. The goal is to learn from them and to transform this knowledge for today's challenges. Various book publications and articles in corporations with colleagues and students bear witness to this research agenda: https://circularwaterstories.org.

Tomas is a PhD candidate at the School of Architecture of the University of Queensland, Australia. His thesis explores urbanisation’s alteration of the natural water cycle and ways to restore it using urban design. He proposes a novel indicator framework for assessing and designing water-sensitive urban precincts. This framework is based on a spatial model of the urban water cycle -the Waterspace model, presented here-, which has been tested on an existing precinct in Brisbane. Tomas is a trained architect and urban planner, and also holds a MSc in Water and Coastal Management. His main research interests are in urban sustainability, adaptation to climate change, and coastal management and planning. He has already deposited his thesis and is currently working at the environmental consultancy Salt, in Lofoten, Norway, where he investigates climate risks and alternative adaptation pathways for Norwegian municipalities, among other pressing environmental issues for coastal communities.
