本研究旨在评估日本最近的“本地生产本地消费”（LPLC）运动，特别关注日本中部大阪市地区的蔬菜。在收集统计数据和空间数据后，我们利用地理信息系统软件，沿着蔬菜流动路径（国家、区域和地方）三个空间尺度对蔬菜生产和消费以及相关能源消耗进行了多尺度分析。大阪市地区消费的蔬菜来自日本各地，我们以 1 公里的空间分辨率绘制了该地区的食品棚地图，以及农田、农民和其他市场的分布。我们还进行了情景分析，通过有机农业和利用城市附近的废弃农田来替代从遥远地区进口的粮食来减少能源消耗。我们发现，目前大阪市地区消耗的蔬菜大部分来自偏远县，这与高水平的能源消耗有关。在大阪市区内，城郊蔬菜种植为区域蔬菜供应做出了贡献，导致市中心80公里半径内约70%的生产/消费比；如果所有废弃农田面积都恢复生产，这一比例将增至75%左右。研究区域的许多地方都出现了将农民和城市居民聚集在一起的有机农业活动，从而促进了 LPLC 的增加。情景分析表明，通过更广泛地采用当地有机农业供当地消费以及完全利用大阪市地区的废弃农田，可以减少超过 1 x 10(6) GJ 的能源投入。
This study aimed to assess Japan's recent "local production for local consumption" (LPLC) movement, with a special focus on vegetables in the Osaka city region of central Japan. After collecting statistics and spatial data, we conducted a multi-scale analysis of vegetable production and consumption along with the associated energy consumption, using geographical information system software at three spatial scales along the vegetable flow paths: national, regional, and local. Vegetables consumed in the Osaka city region came from prefectures throughout Japan, and we mapped the foodshed within this region at 1-km spatial resolution, as well as the distribution of farmland, farmers' and other markets. We also conducted a scenario analysis for reduced energy consumption through organic farming and the utilization of abandoned farmland near a city to replace food imports from distant areas. We found that the large majority of vegetables consumed in the Osaka city region currently come from remote prefectures, and that this is associated with a high level of energy consumption. Inside the Osaka city region, peri-urban vegetable farming contributes to regional vegetable provision, resulting in an approximately 70 % production/consumption ratio within an 80-km radius of the urban center; if all of the area of abandoned farmland were restored to production, this ratio would increase to approximately 75 %. Organic farming activities that bring together farmers and urbanites are emerging in many parts of the study area, contributing to increased LPLC. Scenario analysis suggested that a decrease of more than 1 x 10(6) GJ of energy inputs could be achieved through wider adoption of local organic farming for local consumption and complete utilization of abandoned farmland in the Osaka city region.
