A Study on Changes in Satoyama Landscapes in Kunisaki, Japan
SANO YAE
The Kunisaki Peninsula in Oita, Japan is a site of Globally Important Agricultural Heritage Systems. However, it faces the problem of an aging and declining population. A decrease in the working-age population is leading to deterioration of its traditional rural landscape, known as Satoyama. The purpose of this study was to examine changes in Kunisaki’s society and land use. Based on government population projections, 57.9% of Kunisaki’s population in its 702 agricultural communities will be over 65 years old by 2030. To examine how land use changed in the Morota District, we analyzed aerial photographs taken between 1947 and 2016, and found a large decrease in crop land and a steady increase in forested areas. The increase in forested areas are caused by both plantation and transition from abandoned crop land. Although the proportional area of crop land has consistently declined since 1947, this decrease has accelerated since 2006., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2015/04 -2018/03, Grant-in-Aid for Scientific Research (C), Nagoya Keizai University
