The section of Environmental Technology and Design (ETD) contributes to inter- and transdisciplinary, context-driven and problem/solution-focused research and education for the sake of a better environment. It involves a collaborative design and engineering approach, with social- and environmental-based methods and techniques as operative instruments, as well as the development and application of advanced urban data science and geospatial information technologies to support this primary aim. Research and education blend environmental technology, urban ecology, citizen participation and environmental behaviour at different scales. There is a strong emphasis on the interaction of these fields in terms of theories, methods and techniques, as well as their application via concepts, strategies and spatial interventions, as a significant part of ETD’s research portfolio concerns applied science for and often with public and private partners.
