Abstract:This article examines how social networks among actors in the tourism sector have facilitated the evolution of self-organized institutions for governance on the island of Gili Trawangan, Indonesia. Increasing tourism for SCUBA diving and nightlife is driving rapid social-ecological change and challenges for sustainability in relation to waste management, social-political cohesion and conservation. While strong social networks were a sufficient means to initiate governance among the island's few early businesses in the 1990's and early 2000's, an increasing number of actors (i.e., new SCUBA businesses and hotels) and more tourists are challenging the ability of social networks to be the foundation of effective governance, where there is now an evident need for the evolution of governance to more effectively address sustainability challenges. This article combines quantitative social network analysis with the qualitative analysis of interview data, participant observations and an ethnographic examination of the island's changing social-political sphere of cooperation to examine the evolution of governance. Our results can be separated into two parts. (1) From past to present, examining how governance institutions and collective action have emerged from strong social networks. (2) From present to future, how these social networks are being undermined as the foundation for the island's governance institutions that they created, due to growth and changing social-ecological conditions. This article draws on Evolutionary Governance Theory (EGT) as an overarching frame to examine the linkages between social networks and collective action, looking specifically at the role of multi-level governance, institutional change, path dependencies and discourse analysis.
