Samenvatting

Infrastructure and adjacent areas represent extensive social value. However, infrastructure and areas are still often developed sectoral and independent. In the Netherlands, national spatial policies strive for combining infrastructure and area as one integrated approach as this is expected to result in more spatial quality. Taking this perspective, this article discusses trendy concepts in current Dutch planning, such as: adaptive planning, public and private cooperation and challenge-oriented approaches (‘opgave-gericht werken’ which focuses less on realising a project but more on the current and future issues and challenges in an area). This article argues that these concepts are closely related. Adaptive planning defines the rules of the game and the playing field, within which cooperation may develop. Cooperation is a means for creating spatial quality in interaction within this playing field. After all, generated quality can be considered as a contribution to the specific objectives and interest of the various partners. A challenge-oriented approach is the process for generating spatial quality from synergies in combined infrastructure and spatial development. This article aims to explore the relationships between adaptive planning, public and private cooperation and challenge-oriented approaches and to provide starting points for further research and discussion.
