In this PhD research, the major environmental challenges of our time, such as climate change, sustainable energy transition and scarcity of resources, are approached from a spatial, landscape-architectural perspective. The goal is to accelerate the transition to liveable, low carbon cities. The focus of the research is at the local scale and attempts to turn challenges into opportunities for a better quality of life and living environment. This research contributes to sustainable urban development and emphasizes the role of landscape architecture in this regard as it provides synergies within urban metabolism (flows in the city). It also leads to closer cooperation with other disciplines. New approaches have been developed through SULP some of which have already been successfully applied, for example the ‘Rotterdam Energy Approach and Planning’ (REAP) as well as the ‘Smart City Planner’. Approaches that accelerate the transition to a liveable, low carbon city!
