Information exchange networks among actors for the implementation of SDGs

Abstract

This article emphasizes the importance of actor networks for the implementation of the Sustainable Development Goals (SDG), and suggests how a network perspective can contribute to our understanding of (global) sustainability governance. Actor networks are often driven by homophily, as actors tend to interact with those similar to them. Yet, not least in a context sustainability governance, heterophily of actor cooperation is claimed to be beneficial. In contrast to homophily, heterophily represents situations where actors cooperate with those that are different, and thus combine diverse sets of knowledge and competences. Based on the case of Swiss actors involved in the implementation of the SDG 6 on water in countries of the global South, we use social network analysis and qualitative interview data to study how homophily and heterophily influence actors' information exchange. According to quantitative network data, information exchange between actors is indeed influenced by homophily regarding the type of actor and the policy forums actors are participating in. Nevertheless, we also find evidence for heterophily, as actors tend to exchange information with actors with different methodological foci. Furthermore, qualitative interview data show that actors perceive heterophilous network ties as beneficial for SDG implementation.
