Scientific Real Estate Considerations of Land Value Development and Regulations Including Topographical and Geological Factors Based on the History of Development of Slope Land

Abstract

The history of slope land development in Japan is closely related to the industrial makeup of the area and the economic trends at the time of development. On the other hand, does the monetary value of land（land prices）account for the risk of natural disasters? Research into land rent theory, a subject that has mainly been examined in classical economics, sometimes examines land rent in terms of differences in the fertility of land for agricultural purposes. When considering the “utility” of real estate in real estate appraisal standards in the present age, it is necessary to reflect the value inherent to the physical properties of land, including safety for habitation, agricultural productivity, and cultivation management of farmland, in terms of “utility”, and to use suitable land for residential purposes. In the current social environment, it is difficult for the value of land to be reflected correctly unless regulations are strengthened.
