Urban Farm DB summary
Through multiple regression on fees at growing corporate-run kitchen gardens in metropolitan areas, this paper shows pricing reflects urban land-use factors such as rail access, distance from city center, and surrounding population, discussing expansion potential for private rooftop and non-farmland farms.
Key points
- 1Deregulation of agricultural land laws has led to an increase in private citizen farms in metropolitan areas.
- 2Private citizen farms offer enhanced facilities and services, resulting in higher fees compared to traditional public citizen farms.
- 3Fees for private citizen farms are set based on urban land-use factors such as rail access, distance from the city center, and surrounding population, in addition to facilities and services.
- 4This pricing model challenges conventional arguments that agriculture cannot exist in cities due to differences in agricultural and urban land-use bid-rent curves.
- 5Applying urban land-use bid-rents to urban agricultural land could help curb agricultural land conversion and promote agricultural use of unused urban land.
- 6Public citizen farms, competing with private ones, are expected to focus on more public-oriented initiatives, such as agri-welfare farms.
Abstract and stored text
OpenAlex農地関連法の規制緩和により，大都市圏で民間市民農園が増加している．民間市民農園は従来の公設市民農園に比べ，施設・サービスが充実し，高い料金が設定されている．その料金を重回帰分析した結果，設備・サービスのほか，鉄道でのアクセス，都心からの距離，周辺人口等，都市的土地利用の視点で設定されていることが分かった．これは，農業的土地利用と都市的土地利用の付け値曲線の違いから，都市の中に農業は存在しないとしていた従来の議論では見過ごされていた土地利用である．都市農地に都市的土地利用の付け値を設定することができれば，農地転用の抑制や，都市の未利用地の農業的利用に貢献する可能性がある．また，民間市民農園と競合する公設市民農園は，農福連携農園など，より公共性の高い農園に重点化することが期待される．
Why it matters for urban farming
This research highlights that the economic value of urban citizen farms is significantly influenced not only by agricultural production but also by urban factors such as transportation access, distance from the city center, and surrounding population. This suggests that citizens planning and operating urban farms can create more sustainable and attractive farms by innovating their location choices and services. Furthermore, it implies that new urban farm developments might be possible in locations previously considered unsuitable for agriculture, such as rooftops and unused urban land, by adopting operation models that consider urban value. The focus of public citizen farms on highly public initiatives like agri-welfare is also expected to make citizen farms as a whole a place that meets diverse needs.
