This paper explores and discusses the fairly recent phenomenon of cultural clustering strategies in the Netherlands. Amongst other things based on ideologies of 'enterprise culture', the quest for urban imagery and positioning strategies, the changing spatial fabric of cities and a search for economic and cultural revitalisation, for the past 5-10 years, the formation of cultural clusters has turned into something of an urban cultural development hype. However, what at first glance appears as a common model, often accompanied by boldly expressed slogans concerning the new role of culture and creativity in the physical and economic revitalisation of cities, in more detail unfolds as an ambivalent and conflict-ridden mixture of cultural, economic, social and spatial interests and sentiments. From a short-term perspective, such an eclectic blending of interests and sentiments might be considered as a good opportunity for urban cultural developments within a 'post-modern' urban development regime. However, from a long-term perspective, there is the danger that the divergent sentiments and interests start to undermine and constrain each other, in the end resulting in adverse effects, mutual distrust and a standstill of developments. Following a detailed investigation of five cultural clustering projects in the Netherlands, and based on Zukin's account of the exchange of cultural and economic values in the contemporary city, the paper argues that, in order to get out of this potentially self-defeating situation, and to enable a more sensitive but also strategic involvement of the cultural sector in the governance of cultural cluster projects, it is necessary to develop a more sophisticated understanding of the complex dynamics involved. Central to this is a locally specific appreciation of the changing interaction between culture (place) and commerce (market) in today's mixed economy of leisure, culture and creativity. This implies both a critique and advancement of existing theories concerning the role of culture in urban development and the development of a more detailed comparative perspective on urban cultural policy projects, thus moving beyond overgeneralised perceptions of the developments concerned.

-TransForum is an innovation program which aims to make a substantial contribution to the transition towards more sustainable development of the Dutch agricultural sector. This article describes the scientific foundation and architecture of this program. TransForum operates on the basis of five working hypotheses which together constitute one integrated analytical framework. These hypotheses are: (1) sustainable development is a dynamic system property; (2) sustainable development needs system innovation; (3) system innovation is a non-linear learning process; (4) system innovation requires active participation of relevant key players from knowledge institutes, governmental bodies, civil society organisations and the business community; (5) the program requires transdisciplinary collaboration of all players. TransForum identifies three new innovation strategies: (1) vital clusters; (2) regional development; (3) international agro-food networks; as alternatives to the current arrangements. Innovative projects are organised in these innovation strategies. The aim of the scientific program is threefold: (1) it addresses research questions raised in the innovative projects; (2) it investigates the need for system-innovations and the way in which they can be realized; (3) it designs research projects to test the 5 main working hypotheses of the program. The scientific program is organised in four themes following a cyclic innovation process which is constantly monitored. The cycle starts with people's preferences and images, followed by studies on which inventions are required to achieve a successful innovation. Subsequently, it is investigated how to organize new innovations and transitions and finally, how citizen/consumers behaviour and preferences mobilizes sustainable development, closing the loop. sustainable development / transition / system innovation / networks

This article gives an overview of the present day discourses on the sustainable development of Dutch agriculture. It aims to advance rural sociology by illustrating how these sustainability discourses actually contain completely opposing views of the future of the countryside. A qualitative analysis of interviews done with innovators in the agricultural sector indicates that the different discourses on the sustainable development of agriculture are a natural continuation of the different views of rurality previously identified by Jaap Frouws (1998). The redefinition of Dutch agriculture and the Dutch countryside is still contested; each discourse has its own vision on the sustainable development of the sector and the surrounding space. We conclude, therefore, that sustainable development has not functioned as an unifying concept to help different parties overcome their differences and work on win-win solutions. The sustainability agenda seems to have intensified an already slumbering difference of interests and perspectives, with the utilitarian, the agri-ruralist and the hedonist discourse each incorporating their own sustainability perspective. The hedonist and utilitarian discourses in particular aspire to sustainable agriculture on different scales and with opposing arguments. In a many respects they are polar opposites, and this has consequences for the possibility of bringing together stakeholders working towards sustainable agriculture.

In this article, we argue that current research on sustainable tourism mobility can be divided roughly into two streams. One covers primarily the organisational and technological side of tourism mobility, while the other concentrates on travellers' attitudes. To date, these streams have been organised as separate bodies of research. There is much to be gained by being able to create linkages between the two. To do this, tourism research will have to develop a less generalised and more context-specific approach to travelling behaviour. In this paper, the Social Practices Approach is suggested as an interesting conceptual tool to interrelate current approaches. By giving greater consideration to the contextual dimension of tourism practices, citizen-consumers might be mobilised more effectively as change agents. To analyse the potential roles of citizenconsumers in transition processes towards sustainable tourism mobility, two citizenconsumer-led change processes are differentiated. The first is directed at tourists in their consumer-role, by providers developing sociotechnical innovations enabling and tempting tourists to behave more sustainably, and by incorporating consumer-logics in supply. Second, tourists can be mobilised in their role as citizen-consumers through processes of sub-politics, social movements and political consumerism.
