The conservation and management of natural resources operates in social-ecological systems in which resource users are embedded in social and environmental contexts that influence their management decisions. Characterizing social networks of resource users can be used to inform understanding of social influences on decision making, and social network analysis (SNA) has emerged as a useful technique to explore these relationships. We synthesized how SNA has been used in 85 studies of natural resource management. We considered how social networks and social processes (e.g., interactions between individuals) influence each other and in turn influence social outcomes (e.g., decisions or actions) that affect environmental outcomes (e.g., improved condition). Descriptive methods were used in 58% of the studies to characterize social processes, and 42% of the studies compared multiple networks or multiple points in time to assess social or environmental outcomes. In 4 studies, authors assessed network interventions intended to affect social processes or environmental outcomes. The heterogeneity in case studies, methods, and analyses preclude general lessons. Thus, to structure and further learning about the role of social networks in achieving environmental outcomes, we created a typology that deconstructs social processes, social outcomes, and environmental outcomes into themes and options of social and ecological measures within each. We suggest shifts in research foci toward intervention studies to aid in understanding causality and inform the design of conservation initiatives. There is a need to develop clearer justification and guidance around the proliferation of network measures. The use of SNA in natural resource management is expanding rapidly; thus, now is the time for the conservation community to build a more rigorous evidence base to demonstrate the extent to which social networks can play a role in achieving desired social and environmental outcomes.

“…Another study with injecting drug users in Lithuania found that betweenness centrality was associated with HIV prevalence, highlighting the importance of engaging people with high betweenness centrality as peer educators in HIV prevention interventions (50). Strategically recruiting individuals who occupy certain positions in their networks in line with a recent review of social network strategies to prevent HIV that recommended that future network interventions “optimally use the power of social networks to reduce HIV transmission” (10). To fully understand the role of network position in influencing health leader’s performance in HIV prevention trials, however, research that longitudinally examines the co-evolution of social networks and intervention-related communication patterns is needed.…”

Engaging social networks in HIV prevention interventions, therefore, provides an opportunity to target these network-level factors by leveraging the peer influence processes underpinning associations between network-level determinants and the HIV-related behaviors of network members (10). …”

Structural Network Position and Performance of Health Leaders Within an HIV Prevention Trial

The effectiveness of peer leaders in promoting health may depend on the position they occupy within their social networks. Using sociocentric (whole network) and behavioral data from the intervention arm of a cluster-randomized HIV prevention trial in Dar es Salaam, Tanzania, we used generalized linear models with standardized predictors to examine the association between heath leaders' baseline structural network position (i.e., in-degree and betweenness centrality) and their 12-month self-reported (1) confidence in educating network members about HIV and gender-based violence (GBV) and (2) number of past-week conversations about HIV and GBV. As in-degree centrality increased, leaders reported fewer HIV-related conversations. As betweenness centrality increased, leaders reported greater number of conversations about GBV. Network position was not significantly associated with confidence in discussing either topic. Our results suggest that peer leaders who occupy spaces between sub-groups of network members may be more effective in engaging their peers in sensitive or controversial topics like GBV than more popular peer leaders.

“…7,27,28 Indeed, network-based or peer-interventions targeting a reduction in risk behaviors, such as syringe sharing have been shown to be feasible and efficacious. For example, peer-intervention studies conducted in Baltimore found lower engagement in HIV risk behavior among active PWID who were trained to be peer educators within their networks compared to those who did not receive training.…”

“…However, as noted in a recent systematic review, little is known about how network characteristics are associated with outcomes along the HIV care continuum. 7 As a consequence, while several network based interventions have focused on HIV prevention via reducing risk behaviors 8,9 , these types of interventions should also consider targeting adherence to antiretroviral therapy (ART) and achieving viral suppression.…”

Background People who inject drugs (PWID) who are highly connected within their injection drug networks may be important HIV transmission nodes if they frequently share syringes with other PWID and are not engaged in HIV care. In India, HIV transmission fueled by injection drug use is increasing, however little is known about the associations between injection network size and syringe sharing and viral suppression. Methods We recruited 14,481 PWID between October 2012 – December 2013 by respondent driven sampling across 15 sites in India. Interviewer-administered questionnaires assessed network characteristics, substance use, HIV testing experience, and access to health services. We used multilevel logistic regression modeling to evaluate the relationship between injection drug network size and 1) syringe sharing at last injection and 2) viral suppression among HIV-positive participants (<150 copies/ml). Findings The median injection network size was 3 [IQR: 1–5] and 7% of participants injected with >10 members in the past 30 days. PWID who had >10 members in their network were 1.65 times (95% CI: 1.12 – 2.42, p=0.0111) more likely to have shared a syringe at last injection compared to those in the 0–1 members in their drug networks. Additionally, individuals with the largest injection drug networks were also 31% (95% CI: 0.53 – 0.90, p=0.006) less likely to be virally suppressed compared to individuals in the smallest injection drug networks. Discussion Individuals with larger networks may be important in HIV transmission within injection drug networks since they were the most likely to engage in recent syringe sharing and least likely to be virally suppressed.
