DESCRIPTION:Social networks are increasingly used to explain variation in a
 gricultural decision-making\, including the adoption of innovations\, resp
 onses to environmental change\, and collective action. Recognition of the 
 importance of networks is increasingly shaping intervention programs and e
 xtension strategies that seek to accelerate desirable outcomes\, particula
 rly by targeting highly connected individuals. However\, despite growing i
 nterest in both the explanatory and practical applications of social netwo
 rk analysis\, the strength of the empirical evidence linking network chara
 cteristics to land management and environmental outcomes has not been syst
 ematically assessed. \nThis study provides a systematic review of social n
 etwork literature in the domain of agriculture to evaluate the empirical e
 vidence supporting claims that social network structure influences environ
 mental outcomes. Agriculture provides an important context for this assess
 ment because it contains one of the longest and most extensive traditions 
 of research examining relationships between social networks and behavioura
 l change. Using a systematic review protocol\, we identified and analysed 
 327 empirical studies examining social networks in agricultural settings. 
 \nWe first provide a broad assessment of the evidence base\, examining the
  characteristics of studies\, analytical approaches\, network metrics and 
 outcomes investigated. The review reveals a rapidly expanding field domina
 ted by cross-sectional\, survey-based studies. Degree centrality was by fa
 r the most frequently measured network metric\, appearing in 242 studies a
 nd substantially exceeding all other metrics. However\, fewer than half of
  studies measuring centrality reported a relationship between centrality a
 nd the outcomes examined. Moreover\, among those reporting a relationship\
 , less than half provided strong empirical evidence supporting the claim\,
  suggesting that confidence in effects attributed to centrality may exceed
  the strength of the available evidence. \nWe then synthesise findings fro
 m the subset of studies providing the strongest evidence to examine when a
 nd how centrality appears to influence adoption-related outcomes\, the mec
 hanisms proposed to explain these relationships\, and the contexts in whic
 h they are most consistently observed. We conclude by identifying methodol
 ogical priorities for strengthening causal inference and advancing the evi
 dence-based use of social network analysis in agricultural and environment
 al management.
