人口減時代における近未来の農地利用を考える─食料生産と生物多様性，生態系サービスの持続的な両立を目指して─

抄録

 In recent years we are facing a “declining population era” which means a continuously declining population. Along with population, agricultural activities are going into a decline especially in hilly and mountainous areas. Agricultural ecosystems have several ecosystem functions other than food production such as biodiversity conservation. Although traditional agricultural practices maintained biodiversity, recent agricultural situations may have negative consequences on biodiversity. In this paper, I reviewed the current agricultural situation in Japan, summarized studies on agricultural land use in a macro-scale, and discussed the future prospects for agricultural land use in Japan.
