Tertius gaudens: germplasm exchange networks and agroecological knowledge among home gardeners in the Iberian Peninsula

摘要

BackgroundThe idea that knowledge flows through social networks is implicit in research on traditional knowledge, but researchers have paid scant attention to the role of social networks in shaping its distribution. We bridge those two bodies of research and investigate a) the structure of network of exchange of plant propagation material (germplasm) and b) the relation between a person’s centrality in such network and his/her agroecological knowledge.
