For more than a decade, firms, governmental organizations, knowledge institutes and other relevant actors in the Sloe Area and Canal Zone have been engaged in multiple initiatives dedicated to the sustainable industrial development of their region. In this article, a reconstruction is made of these developments, using Event Sequence Analysis (ESA), to study how actors built and maintained the collaborations that drive these initiatives, and to study the extent to which these initiatives mutually influence each other. The analysis reveals that there are no direct mutual influences between the developments, but that there are indirect influences based on partially overlapping sources of institutional capacity (i.e. the capacity for collective action). Based on the results, several additions are made to existing models of industrial symbiosis that describe the stages through which industrial symbiosis develops. The first addition is the idea that industrial symbiosis can be understood to build on stable intermediate components that develop autonomously from each other. The second addition is that the development of industrial symbiosis itself can be understood as a stable intermediate for more comprehensive developments at a higher system level. The third addition is that the development of industrial symbiosis can be understood to be embedded in a larger social context that influences the opportunities that actors see for collective action towards industrial symbiosis.

One of the assumptions underlying much of the research on Industrial Symbiosis (IS) that has been performed over the past decades is that besides technical and economic feasibility collaboration between firms is of central importance to the development of IS. So far, there has been little systematic research into the process through which firms and other relevant actors build up collaborations for IS. I present Event Sequence Analysis as a research approach that allows for a systematic, longitudinal analysis of process phenomena and I outline the steps to be taken in the application of the approach. I demonstrate the value of the approach by offering a first analysis of how companies in the Canal Zone of Zeeland in the Netherlands build up the institutional capacity that enables them to address the development of IS collaboratively. The analysis reveals that institutional capacity did not build up in a linear way. The generation of institutional capacity enabled the involved actors to engage in increasingly complex byproduct synergies and utility synergies. It also enabled the actors to develop a strategic vision in which they articulated the development of a bio based industrial cluster as a common purpose. This common purpose stimulated the actors to shift their focus from the development of individual synergies to the development of a regional network of such synergies. Event Sequence Analysis proves to be a promising approach to investigating phenomena such as institutional capacity building and the emergence and development of Industrial Symbiosis.

Social Network Analysis (SNA) can be used to investigate complex social systems. SNA is typically applied as a quantitative method, which has important limitations. First, quantitative methods are capable of capturing the form of relationships (e.g. strength and frequency), but they are less suitable for capturing the content of relationships (e.g. interests and motivations). Second, while complex social systems are highly dynamic, the representations that SNA creates of such systems are often static. These limitations can be overcome by balancing a quantita- tive approach to SNA with a qualitative approach. In the article two different approaches that seek this balance are demonstrated. The illustrations show that in this combination quantitative SNA is most useful for revealing system-level patterns, but that a deeper understanding of the mechanisms that produce these patterns is more easily achieved through the interpretation of qualitative data.

This paper aims to contribute to understanding the dynamics of industrial symbiosis. More specifically, we focus on the dynamics of anchoring as they can be observed in the Chinese context of eco-industrial development. We define anchoring as those activities that (typically local) actors perform to create local physical and institutional conditions conducive to the emergence and further development of industrial symbiosis in a specific regional industrial system. We argue that, in the study of industrial symbiosis dynamics, it is conceptually more useful to focus on anchoring as an activity, rather than anchor tenants as actors. Based on a systematic literature review, we distinguish two types of anchoring activities: institutional and physical. We analyze anchoring dynamics in the case of Qijiang Industrial Symbiosis (Chongqing Municipality) in China. We have identified the physical and institutional anchoring activities, the actors responsible for these activities, and how different anchoring activities build on each other over time. Our case study shows that the attempt to bring about industrial symbiosis in the Qijiang industrial park can be described in a richer way than just 'governmental planning'.

Several strands of literature have developed around the ambition to influence or bring about transitions toward greater sustainability. In this context researchers have come to be interested in the types of actors involved in sustainability transitions and the roles these actors play. However, there is a lack of clear definitions of actors, and their roles. Our research takes an exploratory approach and is designed to describe and analyse the actors concerned and to identify their roles in sustainability initiatives. Our aim in doing so is to contribute to the body of scientific knowledge on transitions and to provide sustainability initiatives themselves with helpful information. Data were collected using the Net-Map tool, a well-established method in actor and stakeholder analysis. In our results we identify and define six actor roles: catalysts, opponents, intermediaries, frontrunners, drivers and visionaries. In the literature, particular roles are connected to common actor categories (civil society, governmental actors, private sector, etc.). Our results imply that sustainability initiatives are neither necessarily hindered by the absence of certain actors, nor are they hindered per se by the presence of an actor - rather, a broad mix seems to be helpful.

[Abstract] A participatory backcasting methodology has been developed for the GLAMURS project, entitled participatory backcasting for sustainable lifestyles and a green economy. It consists of two stakeholder workshops; a first workshop for problem exploration and development of visions for sustainable lifestyle and a green economy followed by a second workshop focussing on pathways and implementation.In six regions studied in the GLAMURS project vision workshops have been successfully executed. Thirteen visions have been generated. Visions have been compared on several dimensions including (1) sufficiency versus green growth, (2) individual versus community orientation, (3) governance by government or market, and (4) urban versus rural focus. ; The research leading to these results has received funding from the European Community's Seventh Framework Programme (FP7/2007-2013) under grant agreement Nº 613420
