The Study of Utilization and Issue for Preservation Productive Green's Multifunction

Abstract

The urban green space and the urban farmland play an important role in improving the urban environment. However, the farmland in urban have been decreasing in every year. This study attempts to alter the urban farmland, especially Productive Green Zone, to the parkland for keeping multifunction. This paper presents four choices, (1) to maintain Productive Green Zone, (2) to buy for construction Standard Park, (3) to lease for Leasehold Park with payment, (4) to lease for Leasehold Park without payment. The way of comparing to them is to calculate the cost paid by local government. The details of this cost are (1) the amount of exempt the fixed assets tax and the city planning tax every year, (2) the purchase cost of Productive Green Zone, (3) the payment of lease for the owner every year, (4) the exempt tax every year. To create park choices (2)~(4) includes the park maintenance cost every year. The result shows that to keep Productive Green Zone is the cheapest plan. It exempts about 4.42 million yen every year, so this is the most efficient for local public finance. There are two future issues. The one is to draw up strict model of land owner intent to convert farmland. The other is necessary to compare with some benefits: farming, disposing of farmland, and economic value of green space.
