Such degradation results from various factors, including climatic variations and human activities. We studied inter-annual variations of land cover around Maroua, Northern Cameroon using Landsat MSS data in order to evaluate a degree of land degradation. The results of this study are summarized as follows: (1) We found increases in area of bare land and cultivating land, and a decrease of biomass in savanna vegetation after 1973. These features show a progress of land degradation in the study area. (2) The degradation trends correspond to climatic fluctuation. Especially, area of bare land correlates closely with annual rainfall. (3) About 100 km^2 of the study area shows irreversible degradation between 1973 and 1987.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Department of Geography, Tokyo Metropolitan University"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00200173","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868710","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"Imagawaf, Toshiaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamoto, Katsuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fukuhara, Michikazu"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-04"}],"displaytype":"detail","filename":"20005-30-003.pdf","filesize":[{"value":"607.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20005-30-003.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2916/files/20005-30-003.pdf"},"version_id":"934efe33-ce80-4949-943d-9ca221a7476e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"land degradation","subitem_subject_scheme":"Other"},{"subitem_subject":"inter-annual variations","subitem_subject_scheme":"Other"},{"subitem_subject":"land cover","subitem_subject_scheme":"Other"},{"subitem_subject":"Landsat MSS","subitem_subject_scheme":"Other"},{"subitem_subject":"Cameroon","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Inter-annual variations of land cover in and around maroua, northern cameroon","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Inter-annual variations of land cover in and around maroua, northern cameroon"}]},"item_type_id":"3","owner":"3","path":["553"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2916","relation_version_is_last":true,"title":["Inter-annual variations of land cover in and around maroua, northern cameroon"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:25:26.904378+00:00"}
