概要 We argue that plot exchange based on the component-wise individually rational priority algorithm (Manju- nath & Westkamp 2021) is effective for land consolidation of fragmented farm plots. Using agricultural field p in d ata from farmers cultivating 5ha or more in Iwate Prefecture, Japan, we show the following: First, under the "larger farmer-higher priority" rule, 14.12% of paddy plots can be traded through our plot exchange system; this reduces farmers’ travel time by 6.70%. Second, under the "smaller farmer-higher priority" rule, 20.11% of paddy plots can be traded; this reduces farmers’ travel time by 9.45%. Thus, the system’s effectiveness heavily depends on the chosen priority rule.
