Her research lies at the intersection of critical analysis, projective cartographies and design. Her work focuses on the development of landscape urbanism in times of global warming and the development of strategies that work with water, vegetation and topography. She has published widely and works on design research consultancy projects, mainly for the Vietnamese and Flemish governments.Chiara CavalieriChiara Cavalieri, architect and Doctor of Urbanism (IUAV, University of Venice), is associate professor of Urbanism at the Université Catholique de Louvain (UCLouvain). Over the years, she has coordinated and directed several research activities and regional visions such as ‘The Blue Space’, Eurometropolis Lille–Kortrijk–Tournai (StudioPaolaViganò, Lab-U, EPFL Lausanne), ‘The Horizontal Metropolis’ (EPFL Lausanne), ‘The Language of Water’ (UCLouvain with Latitude), LABOXXI (Atlas, L’urbanisation du 20e siècle dans et autour de Bruxelles). She is currently developing research on water and landscape urbanism in transboundary urban territories, with a particular focus on mapping and representing the territorial dynamics involved.Cecil KonijnendijkCecil Konijnendijk is an urban forestry scholar who currently codirects the Nature Based Solutions Institute, a think tank for the evidence-based urban greening. He is also an honorary professor at the University of British Columbia and a visiting scholar at Wageningen University. Cecil has published widely and has advised international organizations and local authorities in more than 30 countries on the development and implementing of urban forestry programmes and plans.
