A Study on Sustainability of Compact City as a City Strategy in the Population Decrease

本研究的背景是，在人口减少、出生率下降和人口老龄化的背景下，需要制定政策方法来减轻自然灾害的脆弱性，重点关注紧凑型城市在“人工环境”和“社会环境”方面的可持续性。该研究证明了紧凑型城市对两种环境危害的脆弱性，并审查了缓解和适应的政策方法。最后，该研究表明，尽管反城市化正在发生，但它并不被认为是非常可能的“城乡化”。

This study started from the background that, in a population decrease as well as in a declining birthrate and aging population, it was needed to prepare policy approach to mitigate vulnerability to natural hazards with focus on sustainability of compact city in terms of 'artificial environment' and 'social environment.' The study demonstrated vulnerability of compact city to hazards from the two environments and examined policy approaches for mitigation and adaptation. Finally, the study showed that however counter-urbanization was occurring, it was not 'urban ruralization' regarded as very likely.
