| Seed circulation among farmers, which is embedded in composite social networks, is a key process in the dynamics of seed systems that shape crop diversity. We analyzed the daily circulation of biological objects, i.e., cultivated plants (31 species, 284 landraces), within a community of first-generation migrants (16 households, 30 persons) living on the island of Vanua Lava in the South Pacific archipelago nation of Vanuatu. By combining participant observation, ethnobiological inventories, and social network analysis, we investigated how farmer social status and plant biocultural value affect plant circulation. Plant biocultural value was estimated by referring to their local classification according to uses, cultivation practices, growing environments,... |

| Environmentally induced farmer migration is an important livelihood strategy, yet little is known of the effects on the destination region agroecosystem information networks and management practices. In the forest-savanna transition zone (Brong Ahafo Region) of Ghana, where migration from northern regions (migrant) and from neighboring regions (settler) is active, we chart the role of migrant famers and the type of agroecosystem management practices embedded in information networks using a social networks approach. Based on empirical network data from 44 respondents across three communities, we illustrate a diffuse information network, with variable tie frequency between settlement categories (local, settler, or migrant) of farmers. The cohesion of this... |

| Exploitation and degradation of urban green areas reduce their capacity to sustain ecosystem services. In protecting and managing these areas, research has increasingly focused on actors in civil society. Here, we analyzed an urban movement of 62 civil-society organizations—from user groups, such as boating clubs and allotment gardens, to culture and nature conservation groups—that have protected the Stockholm National Urban Park. We particularly focused on the social network structure of the movement, i.e., the patterns of interaction between movement organizations. The results reveal a core-periphery structure where core and semi-core organizations have deliberately built political connections to authorities, whereas the periphery... |

| This paper makes both a theoretical and empirical contribution to a better understanding of how specific forms of network governance play a crucial role in enhancing sustainable development in rural areas. Drawing on the literature on social capital and social networks, I argue that a region has to achieve a certain level of cohesion in the network structure among actors from different societal sectors and governmental levels to strengthen rural sustainable development. However, to sustain positive regional development in the longer term, network structures also need to guarantee fragmentation and flexibility by including actors with varying views and interests. Empirically, the paper looks at the new policy of regional nature parks in Switzerland. The... |

| In the face of apparent failures to govern complex environmental problems by the central state, new modes of governance have been proposed in recent years. Network governance is an emerging concept that has not yet been consolidated. In network governance, processes of (collective) learning become an essential feature. The key issue approached here is the mutual relations between network structure and learning, with the aim of improving environmental management. Up to now, there have been few attempts to apply social network analysis (SNA) to learning and governance issues. Moreover, little research exists that draws on structural characteristics of networks as a whole, as opposed to actor-related network measures. Given the ambiguities of the concepts at... |

| What is social structure, and how does it influence the views and behaviors of land managers? In this paper, we unpack the term "social structure" in the context of current research on institutions, social networks, and their role(s) in resource management. We identify two different kinds of structure, formal and informal, and explore how these link to views of land management and management practice. Formal structures refer to intentionally designed organizations that arise out of larger institutional arrangements; informal ones refer to social networks, based on the communication contacts individuals possess. Our findings show significant correlations between respondents' views regarding land management and their social networks; it is these informal... |

| Local participation of stakeholders in governance of protected areas is considered to be important to natural resource management and biodiversity conservation. Social network analysis (SNA) is a useful tool for analysis because it allows the understanding of stakeholders’ relationships, interactions, and influences through communication networks. We combine quantitative and qualitative data to undertake a SNA for the natural park of Sant Llorenç del Munt in Catalonia, Spain. This is aimed at (1) assessing the structure of the communication network; (2) comparing the informal communication network with the formal participatory bodies of the natural park; and (3) selecting participants for subsequent analyses of the adequate governance... |

| Community based natural resource management groups contribute to landscape scale ecological change through their aggregation of local ecological knowledge. However, the social networks at the heart of such groups remain invisible to decision makers as evidenced in funding cuts and strategic policy documents. Our research is a pilot study of the social networks in two peri-urban landscapes in Victoria, Australia. We describe the social network analysis undertaken with regard to natural resource management issues. The findings are assessed against the qualities of resilience: diversity, modularity, connectivity, and feedback loops. A social network analysis tool is discussed with participants to assess its usefulness on-ground and with agency staff... |

| Access to knowledge on farm management practices is essential for the maintenance of productive agroforestry systems. Farmers who lack the means to acquire farming knowledge from formal sources often rely on information within their informal social networks. However, little research has explored the explicit structure of farmer communication patterns. We examined advice network structures by using farmer attributes, i.e., kin relationships, community involvement, and imitation, to characterize structural positions and investigated the consequences of such structure on farming practices in cocoa agroforestry systems in Ghana, West Africa. Furthermore, we used a multicommunity approach; we constructed networks for four communities to increase replication... |
