A network approach to understand co-management, governance and complex social-ecological systems is becoming part of the toolbox used by researchers in our field, now recently in an article by Marín and Berkes (see below). A bunch of us is trying to form a community of researchers to exchange ideas on how to use network analysis in social-ecological studies and to join our NASEBERRY group, you can mail me (Henrik Ernstson, henrik(at)ecology.su.se).
Andrés Marín and Fikret Berkes uses a 2-mode social network approach in their recent article entitled “Network approach for understanding small-scale fisheries governance“. They make the argument that many studies up until now have focussed on collaborative ties, which might miss how conflicts could drive the structuration of social networks:
[S]tudying only collaborative (or facilitating) relationships may show an incomplete representation of co-management. In the Chilean case, co-management appeared as a dynamic equilibrium between opposing forces: facilitation or collaboration and hindrance or conflict. The existence of conflict and power disputes should not be seen as blocking the functioning of the system but as a driver of change and adaptation 
NASEBERRY – A community would be great to have
Within the field of social-ecological network studies, several other studies are on their way in both marine, terrestrial and urban ecosystems. Further, at the upcoming international conference on social network analysis (SUNBELT) there is a special session on network analysis and natural resource management (June 2010), and several of us are participating in a book project led by Örjan Bodin and Christina Prell to further develop this field.
It is clear that several reserach groups are forming at various universities in the world, and at all continents. We hope our NASEBERRY group could be a good forum for many others to exchange exciting ideas. The name originates from “Network Analysis in Social-Ecological Studies” but has further borrowed its name from a long-lived evergreen tree growing in the Caribbean. The group include scholars that strive to advance both social, ecological and social-ecological network analysis in social-ecological studies. If you would like to join, please contact me Henrik Ernstson (henrik(at)ecology.su.se).
Stay cool. Stay networked. Stay in the (naseberry)tree!
