Abstract

Urban densification is promoted as a solution for reducing emissions and energy consumption. Denser cities are more sustainable, so goes the theory, and can create a ‘city of short distances’, especially if transport hubs are used, assuming that people who live near a station will use the train more often. It is unclear whether this assumption is correct or if it should be considered more spatially and target-group-specifically in the future. The approach has been criticized from different perspectives, e.g. for its negative effects on biodiversity and human well-being and for the unanswered transport planning questions. Our research looks at the conceptual approach from an interdisciplinary perspective and seeks solutions that reconcile the competing objectives of the disciplines outlined above. To this end, we develop an integrated evaluation model that synthesizes and compares the target levels of the different inter- and transdisciplinary approaches. We propose an evaluation at district level. The focus is on the public area, i.e. street space and traffic junctions. A comprehensive literature review has revealed common conflicts and synergies between urban densification and the provision of ecosystem services. While densification can potentially lead to increased pollution and reduced green space, it also offers opportunities to enhance urban ecosystem services through strategic planning and design. By integrating the assessment of ecosystem services in the decision-making process, it is possible to mitigate negative impacts and create more sustainable, resilient cities with healthier and happier dwellers. Only considering the full range of environmental, social, and economic impacts, can we develop strategies that promote both urban densification and ecosystem health.
