本研究は、災害リスクの軽減と復興ガバナンスの観点から、クライストチャーチ市における地震後の土地利用計画について検討するものである。カンタベリー地震後、クライストチャーチでは、住宅地レッドゾーン(Residential Red Zone)、復興計画、暫定的な土地利用規制、ならびに液状化や洪水リスクを組み込んだ改定地区計画(District Plan)が導入された。Ōtākaro Avon River Corridorは、高リスク住宅地を緑地やコミュニティ志向の空間へ転換した事例を示している。本研究は、柔軟かつ暫定的な計画手法が、災害リスクや環境リスクを統合しながら、緊急的な復興と長期的な都市開発を結びつけることができる点を明らかにする。これらの取組は、リスクを踏まえた土地利用ガバナンスを通じて「Build Back Better」を実現するための重要な示唆を提供する。
