Study on the Factors related to the Farmland Diversions in Urbanization Control Area in Sakai City

Abstract

In order to get the basic ideas for preserving urbanization control area in good condition from the viewpoint of town assembly, data are collected on the number of and purpose of farmland diversions from 1990 to 2005 in Sakai city, and statistical analysis is conducted. It is shown that the farmland diversion is decreasing since 1998, but that the diversion to the facilities that can be cheaply built such as open material storages and parking lots is not the case. Also it is shown that the assemblies having large size of land whose distance from urbanization promotion area is less than 250m, as well as assemblies that have longer roads of their width more than 22m in their area make significantly increase farmland diversions. These findings indicate the importance of regulatory control that takes into account the environment of each town assembly in detail.
