Edible wild plants, Sansai as an ecosystem service are possible resources to enhance regional development for depopulated regions. Sansai has been sold at roadside stations called as Michi-no-Eki. The amount of Sansai sold at the roadside station is considered to be determined by the purchasers and by availability of Sansai in the area. The availability is probably affected by land mosaic, proximity between residents and (semi-)natural lands.
We got the data of sales of Sansai 22 road side stations, Michi-no-Eki in Gifu and Aichi Prefectures in 2016, and analyzed geographic conditions that affect sales and items of Sansai. Geographical conditions affecting item composition and sales were analyzed by simple correlation analysis, generalized linear models (GLM).
As a result, 33 kinds of wild plants were sold. The number of units sold per roadside station had a positive correlation with the number of items sold and the number of users, and a negative correlation with the distance from the population center of the nearest-large city, Nagoya. The number of users had a negative correlation with the distance from the center of population. In the GLM analysis using the number of sales per user as the response variable, the model that included only the number of items as the explanatory variables was the best model with the smallest AIC. On the other hand, there was no significant correlation between the number of items and regional attributes such as land use diversity and population density, but a model with a quadratic curve with a high distance of about 115 km from the city was selected by GLM.
The number of Sansai sold was affected by the number of visitors and the number of items sold. The former is mainly affected by the distance from the city center, so it is difficult to improve it. However, the latter is expected to be improved by roadside stations and sellers.
