ABSTRACT


Social networks among actors and stakeholders are gaining attention in studies of natural resource management, particularly those of adaptive management based on different forms of participation and co-management. In this sense, social networks have primarily been envisioned as enabling different actors to collaborate and coordinate management efforts. Here, we continue the discussion initiated by Newman and Dale (2005), which highlighted the fact that not all social networks are created equal. We discuss the relation between some structural characteristics and functions of social networks with respect to natural resource management, thus focusing on structural implications that are often overlooked when studying social networks within the context of natural resource management. We present several network measures used to quantify structural characteristics of social networks and link them to a number of features such as learning, leadership, and trust, which are identified as important in natural resource management. We show schematically that there may be inherent juxtapositions among different structural characteristics that need to be balanced in what we envision as social network structures conducive to adaptive co-management of natural resources. We argue that it is essential to develop an understanding of the effects that different structural characteristics of social networks have on natural resource management.

INTRODUCTION


Social networks are gaining attention in discussions of adaptive natural resource management based on different forms of participation and co-management (Holling 1978, Schneider et al. 2003, Anderies et al. 2004, Olsson et al. 2004, Ostrom 2005). This is a response to Tompkins and Adger (2004) and Newman and Dale (2005). Tompkins and Adger (2004) argued that social networks between stakeholders and actors can build community resilience and increase the adaptive capacity for environmental change. Newman and Dale (2005) extended this idea and noted that “not all social networks are created equal,” and that a dynamic balance between bonding and bridging links is needed. Bridging links extend outside the community and provide access to a diverse set of resources, whereas bonding links within the community are necessary to absorb these benefits. Newan and Dale (2005) thus point out that social networks are more than just binary variables that either exist or do not exist. Here, we further unravel the social network variable to show its multidimensional nature when the structure of the social network is taken into account.

Thus, we address social networks as real observable phenomena that can be measured using quantitative techniques (Marsden 1990) and analyzed using social network analysis (Degenne and Forsé 1999, Scott 2000). The social networks primarily in focus are those that contain different stakeholders within a fairly well-defined management area and can be used to mobilize and maintain the co-management of common-pool resources.

We begin by explicitly examining the relation between the structures and functions of social networks. We ask the question: How does the structure of a social network affect the ability to manage natural resources adaptively? We take our standpoint from a number of features identified in the literature as important for adaptive natural resource management and discuss how these are linked to network structure based on a review of social network literature. Secondly, we present some network measures that can be used to quantify network structure. Finally, we discuss how social roles and leadership in co-management can be understood based on their structural positions. Because most research on social roles in adaptive management lacks a structural perspective, we hereby hope to add to the understanding of these roles.



ROLE OF SOCIAL NETWORK STRUCTURE FOR NATURAL RESOURCE MANAGEMENT


Research has identified a number of features that are seemingly important for the adaptive management of ecosystems. We have chosen six of these as examples to be discussed further: social memory, heterogeneity, redundancy, learning, adaptive capacity, and trust (Table 1). In Table 1, we describe how each of the features is linked to social network structure and provide examples of measures (Table 2) that can be used to assess how each feature is affected by the network structure. Neither the list of features nor the linked structural characteristics should be viewed as exhaustive. They serve merely to illustrate the interaction between function and network structure within the framework of resource management.

It is evident that a network structure that enhances one feature may simultaneously inhibit another; an example is centrality (Table 1). A high degree of centrality may in some respects be very good for facilitating the process of solving simple tasks because relevant information can be relayed and synthesized to a few actors who can make a decision and take action (Leavitt 1951). For the same reason, high centrality might also be good in times of change when effective coordination of actors and resources may be needed. On the other hand, social networks in which a few individuals have a high degree of centrality may lead to increasingly centralized decision making, which in turn may have negative effects on, for instance, learning because it reduces the access of individual actors to multiple sources of information (Weimann 1982, Abrahamson and Rosenkopf 1997).

Density is another network measure that may have different effects depending on the feature in focus. For example, high density may contribute to the strengthening of trust between individuals and groups and thereby also increase the possibility for social control (Granovetter 1985, Coleman 1990, Pretty and Ward 2001). This is important in two ways; first, it decreases the risk and cost of collaborating with others, which is an essential prerequisite for collective action and collaboration (Ostrom 1990, Cohen et al. 2001, Burt 2003). Second, it promotes the development of and compliance with mutual norms in relation to what is considered acceptable with respect to resource use and extraction (Coleman 1990). High density may also benefit the spread of information through increased accessibility to information (Weimann 1982, Abrahamson and Rosenkopf 1997). However, very high density of relations among actors can result in homogenization of experiences and knowledge (Oh et al. 2004, Bodin and Norberg 2005, Crona and Bodin 2006). This occurs, for example, through a high density of interaction among individuals that leads to a situation in which all individuals tend to adopt similar perceptions of issues at hand.

A final example of a relevant network measurement is betweenness (Freeman 1979). This is a measure that can be used to describe the degree of modularity in a network. Modularity is the tendency to form multiple groups; a network with high modularity consists of several internally dense groups that are either isolated or relatively loosely connected to each other, i.e., clusters or cliques. High modularity increases the ability of the different groups to develop partly distinct knowledge systems such as local ecological knowledge (see Ghimire et al. 2004, Crona and Bodin 2006) about the same ecological system, which in turn bestows the ability to perceive different changes in the ecosystem that may be conveyed to others. High modularity thereby opens the network to a potentially large number of feedback possibilities from the ecosystem to the management system, i.e., it enhances monitoring, provided that the groups of actors in the network are not completely isolated. Because of high density within separate groups of actors, a very high degree of modularity can, however, foster a mind-set of “us vs. them,” which consequently contributes to locking actors in fixed political positions and limiting their common ability to act and seek consensus (Borgatti and Foster 2003). The network measurement of betweenness can also be used to identify individual actors occupying bridging positions, that is, contributing to the linking of otherwise isolated groups (Freeman 1979, Gould and Fernandez 1989).



ROLES AND STRUCTURAL POSITIONS IN NATURAL RESOURCE MANAGEMENT


In addition to the abovementioned features, the importance of leadership and other social roles in adaptive natural resource management has been discussed (e.g., Folke et al. 2003). Many of these roles coincide with what Frances Westley describes as social entrepreneurship (F. R. Westley, personal communication; see also Westley and Vredenburg 1997). In social network theory, scholars have often sought to explain roles based on structural position (e.g., Scott 2000, Borgatti and Foster 2003). Here, we highlight the structural position that, in our view, seems to be one of the most important for social and institutional entrepreneurship: the broker.

Brokers are individual or organizational actors who carry many exclusive links, that is, links to groups that would otherwise not be in direct contact with each other (Burt 2003). In relation to Newman and Dale’s (2005) discussion, we can view the broker as the actor who embodies the bridging links of the community. Consequently, and in relation to our discussion on different network measures, the broker acquires a high score of betweenness (Table 2) while also linking otherwise disconnected groups. Thus, a broker, merely by its structural position, gains access to many pieces of group-specific information captured inside the different groups, which allows the broker to synthesize a large knowledge pool. In addition, through its structural position, the broker learns about the inner life of many of the different groups and therefore achieves, through the position, an advantage in knowing which groups or individuals to connect and not to connect, how to connect them, and when (Burt 2003). In times of crisis, this is critical knowledge. Burt (2003) calls this capacity acquired by the broker adaptive implementation, i.e., the ability to navigate in a continuously changing social landscape and coordinate the actions of a network. The broker, which in a real setting could be an individual, a group of individuals, or an organization, can thus find new collaborative solutions for different situations at different points in time. It is also clear from this description that brokers are powerful actors in the sense that they can control the behavior of social groups and the information flow between groups in the network to a higher extent than can other actors. Burt (2003) further points out that brokers, with early access to critical information, often create new understandings and see new opportunities that other actors never recognize. The broker seems gifted with creativity and could be critical for the innovative and adaptive capacities of communities that Newman and Dale (2005) search for (see also Westley and Vredenburg 1997).

The broker is thus an important position and plays a critical social role in adaptive natural resource management. Other social roles important for such management have been identified (see, for example, Folke et al. 2003). Although a discussion of these roles lies outside the scope of this reply, we believe that an understanding of their importance can be further improved through discussions similar to the one presented here for brokers.



CONCLUDING REMARKS


We have discussed the relation between social network structure and function in natural resource management. We have furthermore highlighted network measures used to quantify structures in social networks and linked these to features identified as important in enhancing adaptive management of ecosystems. As in Janssen et al. (2006), our discussion deals with structural characteristics of networks, but with a stronger focus on the interplay between social structures and actors. We have shown, if only schematically, that there may be inherent juxtapositions between different structural characteristics that need to be balanced in what we envision as social network structures conducive for co-management of natural resources. One beneficial structure for this appears to be a network containing separate groups with internal trust and with some degree of trust among them, linked together by motivated brokers who are interested in using their structural positions to initiate and maintain adaptive co-management. This structure could be seen as supporting the dynamic balance between bonding and bridging links envisioned in the reply by Newman and Dale (2005), in which the broker embodies the critical bridging links. It also resembles the advantages of intermediate modularity as discussed by Webb and Levin (2005), who took a mainly ecological perspective. However, there are several issues we have not addressed. These issues relate to (1) problems of scale matching, i.e., how network structures match the different scales of ecosystem processes, both temporal and spatial; (2) temporal dynamics, i.e., how different structures can provide different benefits at given phases of the management process (compare with adaptive cycle phases as described by Gunderson and Holling 2002); (3) the role of leadership in organizational change (Danter et al. 2000); (4) the dynamics of structures, i.e., how and why network structures change and the effects on management; and (5) the social effects of structure on the distribution of power and influence. To increase our knowledge of the structures that serve adaptive natural resource management, we think that more emphasis should be placed on developing an understanding of the effect of different structures on co-management (compare Carlsson and Berkes 2005 and Crona and Bodin 2006). This line of research should be based on empirical studies of social networks in which we can use many of the methods and techniques already available and under constant development by a growing group of transdisciplinary-oriented researchers that has been partly assembled in the International Network of Social Network Analysis (see http://www.insna.org). In our current projects, we are generating empirical data on the networks of existing management structures, and we know that other researchers of natural resource management are using similar approaches. We look forward to the results of this ongoing effort and a continued discussion on the role played by social networks in the management of ecosystems.
