Abstract
This study develops amethod thatidentifies social networks formed through the irrigation water users. Adjacency matrixes of farmers who cultivate neighboring parcels are used to construct network graphs, in which the upstream-downstream relationships of each parcel's cultivators are clarified based on GIS. Weexamine the relationships between the network structure indices and the cultivators' recognition of irrigation practice and derive several features of the degree of centrality from network graphs. Afuture application of the network analysis to consensus building about irrigation facility management isfinally discussed.
