Outline of Final Research Achievements

This paper explains the characteristics of land use management after three mega coastal disasters: Canterbury Earthquake in Christchurch, Hurricane Sandy in New York and the Great East Japan Earthquake in Tohoku region. These three cases have led to spatial transformation after each disaster, thus, examined as mega-disaster. Three ability; sustainability, livability and resilience in the built environment were utilized to infer the expected outcomes and challenges in post-disaster land use management. Municipalities in each country combined and operated land use management tools, which can be adapted to local context, in order to reduce coastal risks and assist survivors’ housing reconstruction, although several challenges were found as an integrated system which cannot cope with mega disasters.

Academic Significance and Societal Importance of the Research Achievements

東日本大震災のような沿岸域を襲う巨大災害の長期的復興過程では被災者の居住移転や行政による土地利用計画変更により、アーバンフットプリントが短期間かつ大幅に変容する。そのような不確実性の高い復興に対応できる計画論を提起した。
