Agricultural systems are important for the livelihoods and food security of millions of people. These systems are increasingly interconnected across scales and face challenges in responding to multiple, and coalescing types of environmental, social, and economic change. Most studies on how actors respond to change have focused on farmers and farming communities. In this study, we investigate the connectivity of farming systems to markets, to understand how social relationships across the supply chain influence how actors respond to multiple types of changes. We used a participatory network mapping method to interview actors across a fruit supply chain in the Western Cape, South Africa, that is connected to both global and national markets. We identified droughts, climatic variations, changes related to the COVID-19 pandemic, and other social shifts as the most important changes affecting the production and trade of fruit in this region. We also identified three types of responses to these changes: i) responses concerning the dynamics of trade relationships (e.g., changing or maintaining trade relationships); ii) responses based on changes at the individual level (e.g., changes in farm management); and iii) responses based on social relationships (categorized into four types, namely collaboration, knowledge transfer, financial assistance, and marketing coordination). Within these four types, we found that different types of social networks, that include actors operating at different scales and within and outside of supply chains, mediate responses to change. We also found that networks of collaboration, knowledge exchange and financial assistance show a positive correlation, where actors with an export orientation engage in multiple social relationships that enable responding to changes. However, we found limited participation of local market actors in most of these networks. Further investigating these social networks, and the actors participating in them, is essential to better understand and anticipate how and why agricultural systems respond to multiple types of changes, ultimately influencing their trajectory in an increasingly changing world. • Multiple types of changes are together affecting the production and trade of fruit. • Social networks across supply chains are crucial to respond to such diverse changes. • Responses can rely on collaboration, knowledge, financial and marketing relations. • Actors' uneven network participation influence their capacity to deal with change. • We developed and applied an adaptation of a participatory network mapping method.

Global change is threatening the production and livelihoods of millions of smallholders. The capacity of smallholders to deal with such changes is influenced by the increasingly complex trade networks that connect them to local and global markets. Moreover, the social relationships (e.g., trust, reciprocity) in which these trade networks are embedded likely influence smallholders' capacity to respond to change. However, the prevalence and influence of such "social embeddedness" of trading across different fisheries and agricultural small-scale food systems is still largely unknown. Here, we characterize the social embeddedness of trade networks in small-scale food systems across different production and institutional contexts. We then explore how actors in small-scale food systems could respond to environmental changes in relation to their existing trade networks. We used a methodology based on the qualitative comparison of three different case studies of small-scale fisheries and agriculture in Mexico and South Africa. We analyzed and compared expert interviews among case studies and against the backdrop of embeddedness theory and a previous empirical study. We found key similarities in the level of social embeddedness of trade networks across cases. For example, business relationships characterized by stability and trust prevailed, whereby smallholders are often interdependent through networks of connected traders. There were also differences across cases, such as the higher formalization of business relationships in the agricultural cases, and the influence of institutional and country-specific factors on trade structures. Actors mostly responded to environmental change based on their existing trade networks, although these networks were also subject to change. The findings allowed us to propose more detailed hypotheses outlining how social embeddedness in trade networks play different roles in responding to environmental changes. These hypotheses aim to inspire future research toward the improved understanding of trade networks' influence on small-scale food systems' resilience. [ABSTRACT FROM AUTHOR]

Abstract: We investigated the capacity of a natural resource governance system to absorb a disturbance while maintaining its major structures and functions (defined as institutional resilience). Exemplified by East German recreational fisheries governance being disturbed by the German reunification, we studied why in five out of six East German states the former centralized governance system persisted while in one state a decentralized governance system was implemented. Based on resilience thinking and new institutional economics, three analytical steps were developed to assess: (1) the structure and function of the governance system, (2) the attributes of the disturbance and the reorganization process, and (3) human motivations. The centralized system persisted because leading managers wanted to preserve customary structures and functions, minimize transaction costs of change, and maintain powerful positions. This was possible because of their influential positions in the reorganization process. Our results suggest that in externally induced, fundamental, and rapid disturbances decision-makers tend to prevent transformations in their governance system. However, key managers in the sixth state faced the same disturbance but their lack of leadership and an emerging rivalry for fishing rights facilitated a transformation to decentralized governance. Thus, attributes of disturbances can be leveraged by actors' motivations in the reorganization process. [Copyright &y& Elsevier]
