A Citizen Science Approach to Build a Knowledge Base and Cadastre on Earth Buildings in the Weinviertel Region, Austria

Clay played a decisive role as a building material in the Austrian Weinviertel region. Its traditional use in vernacular architecture started to disappear in the 19th century, triggered, for example, by upcoming industrial processes to produce construction materials such as burnt bricks, and by making them available as mass building products in course of the time—even for vernacular purpose and at remote places. Following a debate on ecological sustainability during the last decades, the striking advantages of clay as a building material have been rediscovered. However, to support restoration activities and develop new uses, a vital and profound knowledge of properties of the local clay and its traditional local use is required. It is therefore important to increase the knowledge of this unique heritage among the local population and the scientific community. This article aims to present the development of an earth building cadastre (Lehmbaukataster) based on an innovative Citizen Science approach using mobile technologies for activating and integrating the local population with specific local and historical knowledge of earth architecture in the Weinviertel. The results show that citizens can provide essential information to develop a cadastre on earth buildings. Supported by a web application with GPS location facilities, camera, and low entry barriers, citizens can contribute to the expansion of the scientific database. The research results are a strong impetus for the development of strategies for the valorization and protection of cultural heritage

Urban Living Labs as a Driver for Sustainable Food-Water-Energy Innovations

The Food-Water-Energy (FWE) nexus provides a useful frame for considering sustainable urban development, due to the inevitably close linkages among demand for energy, freshwater and food by the growing urban population, and the availability of these resources. To facilitate sustainable development on a global scale, local and regional solutions concerning food, water and energy challenges need to be established and tested. The exchange of best practices and their potential transfer and upscaling should be fostered. The project GLOCULL (Globally and Locally-sustainable Food-Water-Energy Innovation in Urban Living Labs) has been initiated by an international consortium to address the above-mentioned needs: to create evidence of potential solutions with respect to FWE nexus in seven Urban Living Labs, to share results and experiences, and to provide methodological and practical guidelines and recommendations, with a local and global scale outlook. Urban Living Labs (ULLs) represent an experimental approach of university involvement in a real-world setting, where academic and non-academic actors, including local administration and stakeholders, collaborate on various urban development challenges. Despite the recognition of ULLs as a promising form of urban governance on the EU level (EU 2011), their successful implementation requires further evidence-based elaboration (De Kraker et al. 2016). Each of the GLOCULL partners (the consortium includes: Maastricht University / Netherlands, Leuphana University Luneburg / Germany, The University of Natural Resources and Life Sciences, / Austria, Arizona State University / United States, University of Sao Paulo / Brazil, Lund University / Sweden and Stellenbosch University / South Africa) has developed and implemented experiments focusing on local innovations in various aspects of the FWE nexus, within an ULL. The innovations have been co-created by universities and non-academic partners in each country, using transdisciplinary approaches, resulting in co-production of knowledge, shared with the international project partners. Moreover, flow- and causal-loop diagrams were used to integrate knowledge gathered through participatory, integrated assessments in each of the implemented experiments. The impacts of the project include: the academic impact through advancing knowledge on sustainability transitions through ULL in the FWE nexus and different economic and societal impacts. The latter provides evidence on the local and global sustainability of local food systems, the acceleration of the transition towards sustainable food system, the integration of the FWE nexus and related inputs into decision-making and the contribution to practice partners (local individuals and organisations) through facilitating closer collaborative relationships, network-building and solution orientated approaches to their FWE challenges. Furthermore, the project is also focusing on capacity building. Practice partners are developing technical and personal skills, as well as individual and collective agency, and are sharing their practice and lessons institutionally. This should help to strengthen scholars-local actors-collaboration and co-production of knowledge. An evaluation and case study reporting framework is being developed by the partners to reflect on and assess the implementation of each ULL and compare the process and outcomes across the seven ULLs. Moreover, local and international partner experiences will be synthesised into an implementation guide for practitioners and a participatory assessment toolkit.
