Walk further and access more! Exploring the 15-minute city concept in Oslo, Norway

Abstract

The 15-minute city theory has recently become a popular paradigm in urban development. It claims that everyone should have access to the essential services, facilities and green spaces within a 15-minute walk. This article tests this concept in Oslo, Norway using a mixed-methods approach, based on a Geographical Information Systems (GIS) analysis of accessibility, review of relevant plans, interviews with planners and a case study of the Hovinbyen area. The objective was to find out to what extent Oslo is a 15-minute city, and discuss how this concept can be integrated in urban planning strategies more generally. The study shows that the central part of Oslo is already a 15-minute city, and that several areas are transforming in this direction. However, many suburban neighborhoods have low accessibility scores, and, according to the plans, will likely not change much in the future. This article argues that the 15-minute city concept cannot serve as the main development strategy, but such an analysis can be useful as a diagnostic study or to assist planning in rapidly changing areas or city extensions. The concept can therefore be considered as a flexible tool to support other planning strategies that share the same goals and ambitions. Any interventions that such accessibility analyses suggest should be contextualized and developed in combination with other qualitative assessments and in partnership with local communities.
