In Japan, the seacoast law is the institutional framework most closely related to integrated coastal management, but it does not have enough authority. At present, integrated coastal management is not satisfactory. Reviewing the time scales of various elements in coastal management, we understand that natural processes normally have much longer time scales than those of socio-economic processes. The natural coastal geography was roughly formed during the-Holocene glacial retreat until 6,000 years ago, whereas rapid change has been occurring due to economic development during the past 70 years since the second world war. Since we cannot prevent long-term natural processes, socio-economic activities should be consistent with them. The spatial scale of natural processes can be defined as a length of coastal zone that roughly covers from the input to the output of natural flows such as longshore sediment transport and nutrient budget. Thus, the same type of coast can be seen for more than several tens of kilometers of coastline. This can be defined as a unit of coastal zone subject to integrated management. On the other hand, socio-economic activities have much smaller scales. Development of ports and airports, energy storage bases and recreational beaches has scales of at most several kilometers and is mostly within a city, town or village. Based on the above analysis, a two-layer management model is proposed. For the upper layer that covers an almost closed natural system, basic policy should be given for the sustainability of natural processes by maintaining geography and keeping balance in the flow of fresh water, nutrients, and sediment. For the lower layer, development and conservation activities should be planned and implemented in accordance with the policy of the upper layer through consensus building.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海洋政策学会"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"磯部, 雅彦"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-02-13"}],"displaytype":"detail","filename":"27-46.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"27-46.pdf","url":"https://kutarr.kochi-tech.ac.jp/record/255/files/27-46.pdf"},"version_id":"05a98a48-8499-4960-8507-a8950bde82e7"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"総合的沿岸域管理の枠組み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"総合的沿岸域管理の枠組み"}]},"item_type_id":"2","owner":"2","path":["5"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-25"},"publish_date":"2016-03-25","publish_status":"0","recid":"255","relation_version_is_last":true,"title":["総合的沿岸域管理の枠組み"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T13:40:14.800697+00:00"}
