While a cost-benefit analysis is usually \nconducted for flood protection projects to confirm the viability of any new project, long-term \neconomic analysis at the river basin or the regional scale has rarely been conducted. Policymakers \nneed evidence that investments in flood protection contribute to regional growth. This study \nproposes a methodology for economic analysis of flood protection investments at the river basin \nscale and applies it to the Natorigawa River basin as a case study. The study estimates benefits, \nboth past and future, by reducing damage caused by observed and simulated floods. It finds that \nthe methodology is applicable and investments over the last seven decades in the river basin have \nbeen efficient, with an estimated benefit-cost ratio of 6.1. The methodology needs to be further \nsimplified for application to developing countries, given the limited data and capacity in these \ncountries. Moreover, methods for estimating the effects of climate change and the cost of \nreplacing facilities need to be developed.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_full_name_3":{"attribute_name":"著者（英）","attribute_value_mlt":[{"names":[{"name":"Ishiwatari,Mikio","nameLang":"en"},{"name":"Sakamoto,Masashi","nameLang":"en"},{"name":"Sasaki,Daisuke","nameLang":"en"}]}]},"item_10001_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18884/0002000059","subitem_identifier_reg_type":"JaLC"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"JICA Ogata Sadako Research Institute/緒方貞子平和開発研究所"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-02-17"}],"filename":"Estimating the Economic Viability of Long-Term  Investment in Flood Protection: Case Study of the Natorigawa River","url":{"url":"https://www.jica.go.jp/jica_ri/publication/research/__icsFiles/afieldfile/2023/09/11/Research_Paper_No.4_rev1_1.pdf"},"version_id":""}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Investment for DRR, Cost-benefit analysis, Flood simulation, Evidence-based  policymaking","subitem_subject_language":"en"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Estimating the Economic Viability of Long-Term Investment in Flood Protection: Case Study of the Natorigawa River","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimating the Economic Viability of Long-Term Investment in Flood Protection: Case Study of the Natorigawa River","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"18","path":["674"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-09-01"},"publish_date":"2023-09-01","publish_status":"0","recid":"2000059","relation_version_is_last":true,"title":["Estimating the Economic Viability of Long-Term Investment in Flood Protection: Case Study of the Natorigawa River"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2025-04-16T04:34:37.023114+00:00"}
