Since the Millennium Ecosystem Assessment, ecosystem science domain has made tremendous progress in the study of ecosystem services, but debates on neglected cultural ecosystem services (CES) have persisted. A recent approach established by the Intergovernmental Panel for Biodiversity and Ecosystem Services (IPBES) identifies and advocates incorporation of the CES through the role of local knowledge across other ecosystem services. However, approaches and tools that enable engagement of CES are limited. In this study, we examine how cultural contexts influence the appreciation of different CES, by identifying the behavioural aspects and the indigenous knowledge that has evolved on the basis of Social Network Analysis (SNA). SNA measures the network of relations between people and groups developed traditionally for a long time and their relational values with natural resources and ecosystem services. Through a comprehensive literature review of scholarly research published in Scopus data base, this study explicitly illustrates the interrelationship between SNA and CES. Keywords associated with SNA and cultural ecosystem services including forests, fisheries and agriculture (farming) were used. It was found that various aspects of social network uphold relational values of cultural importance and enhance resilience in groups amidst the social changes and times as societies progress. For instance, in the case of homophily, actors who are attracted to one another chose to interact in their defined network (e.g. fishing network) forming a strong social capital. Consequently, they shared similar beliefs and values that were eventually handed to the next generation of the network which shaped their heritage and identity. Social learning networks in various communities were also found to play a key role in information exchange and knowledge sharing among members compared to information from foreign technical experts. To fully integrate CES into sustainable decision making, this review suggests incorporation of the analysis of social networks formed in different cultural contexts globally.
