Landscape is an important public interest with social, cultural, ecological, and environmental dimensions. It is central to the formation of local cultures and contributes to human well-being. Some areas are protected by supranational agreements that have significant international value. The European Landscape Convention (ELC) calls for integrating landscape considerations into other policy areas such as motorway planning that may directly or indirectly impact the landscape. The key challenge is the integration of existing institutional backgrounds and governing traditions. This paper compares how two qualitative case studies managed landscape protection while planning motorways. Specifically, we examine two internationally protected areas – one in Hungary that focuses on nature and one in Sweden the focuses on culture – to consider how these areas were assessed during the planning of the new motorways. Analysing the cases through the theoretical lens of institutional interplay, we found that the main differences between the two cases can be attributed to the different governing traditions and interpretations of landscape. 相似文献

Intermodal road-rail freight transport works best within markets with relatively large flows occurring over long distances, which corresponds poorly to the current demand for transport in the European Union. The purpose of this paper is to compare the capabilities of conventional European intermodal transport, with special reference to the competitiveness in markets with small flows over short distances, and to explore innovative concepts. Using a technological systems approach, key functions are identified as being the inducement and blocking mechanisms that affect the development and diffusion path of this 'small flows over short distances' (SFSD) system, providing a tool for empirical delineation of the system. These concepts are illustrated and analysed through a case study of the Swedish development project Light-combi. The results show that market and financial uncertainties, insufficient network connectivity and policies favouring the existing technology paradigm, severely hamper the development and diffusion of SFSD systems. 相似文献
