Metropolitan regions result from spatial rescaling processes and region formations and are considered as "soft spaces of governance", referring to international debates on the "new regionalism". This paper addresses the criticism that the focus on competitive metropolitan regions distracts from the need for action on classic spatial planning issues. For this, the paper examines and discusses the institutional integration of regional planning in the German metropolitan regions and the activities of regional growth management as well as the regulatory intensity of regional plans based on a group comparison of metropolitan regions. As a result, the thesis of an institutionally fragmented regulatory growth management by regional planning can only be confirmed for a few metropolitan regions, where no relevant institutions and instruments are implemented in the core area. Regarding the "soft" instruments of growth management, the situation is very different. Here, the action potential is not yet fully utilized, even in metropolitan regions with strong institutional cores. [ABSTRACT FROM AUTHOR]

As a contribution to the debate on deregulation of spatial planning and lean regional plans, this paper presents the first long-term study for Germany analysing the regulatory intensity of all regional plans legally valid in 2017 on the topics of settlement and open space development over time. As a final result, the assumption of a general deregulation and streamlining of regional plans cannot be confirmed. In contrast, changes in the legal basis, such as the priority of inner over outer urban development, have led to a continuous increase in the regulatory intensity over time, particularly in the case of positive growth management policies with an active role of regional planning. At the same time, there is evidence of streamlining tendencies in some states, which can partly be interpreted as deregulation tendencies. To date, however, they are merely an expression of state-specific ways of shaping regional planning and not a sign of an accelerated deregulation competition. [ABSTRACT FROM AUTHOR]

In Germany and Switzerland, land use and urban sprawl there has been a central topic of public debate for several years. Cantonal structure plans in Switzerland as well as state and regional plans in Germany contain binding regulations for managing settlement development. Studies that examine the implementation of these regulations are lacking. This paper analyses the implementation of selected instruments of supra-local spatial planning for managing settlement development in Germany and Switzerland using the Policy Arrangement Approach. The case study covers the regions Oberland (Bavaria), Südlicher Oberrhein (Baden-Württemberg) and the cantons of Zurich and St. Gallen. The results show that actors implement spatial-planning instruments in situative negotiation processes in which they exploremargins and alternatives. Central to these processes is a regional specific overlapping of (i) interlinkings of formal and informal instruments, (ii) the interplay between local autonomy, supra-local control and superordinate context factors, and (iii) the overlapping of supra-local and regional discourses. The results show that the Policy Arrangement Approach helps to better understand how spatial planning works. [ABSTRACT FROM AUTHOR]
