This paper presents a literature review examining the role of social capital in adopting sustainable agriculture, given the growing importance of sustainable agriculture for addressing climate change, food security, and resource scarcity. The review focuses on exploring the construct of social capital and its key dimensions and reviewing the impact of these dimensions on adoption. A Web of Science (WOS) database search identified 17 eligible articles for inclusion following a screening process. The review highlights that various social capital dimensions emerged from previous studies. However, these dimensions can be grouped into three primary constructs of social capital; social network, social norm and social trust. This paper also discussed how these three constructs could lead to better adoption of sustainable agriculture. The findings of this paper provide an understanding of social capital's role in promoting sustainable agricultural practices. By unpacking the construct of social capital and examining its dimensions and influence on adoption behaviours or outcomes, this paper contributes to a better understanding of the factors that influence farmers' decisionmaking processes and highlights social capital's importance in achieving sustainable agricultural development. Ultimately, this review can promote sustainable agriculture and enhance the sustainability and resilience of global food production systems.
