This study seeks to understand why rice farming is so productive in this region; analyzing this situation from the viewpoint of the management efficiency of large versus small scale irrigation schemes. Contrary to popular belief, the study found that farmers in large-scale irrigation schemes achieve significantly higher yields and profits than those in small-scale irrigation schemes.","subitem_description_type":"Abstract"}]},"item_6_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18884/00000751","subitem_identifier_reg_type":"JaLC"}]},"item_6_issue_6":{"attribute_name":"号","attribute_value_mlt":[{"subitem_issue":"Working Paper;105"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takeshi, Sakurai","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"911","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-04-26"}],"displaytype":"detail","filename":"JICA-RI_WP_No.105.pdf","filesize":[{"value":"393.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"JICA-RI_WP_No.105.pdf","url":"https://jicari.repo.nii.ac.jp/record/757/files/JICA-RI_WP_No.105.pdf"},"version_id":"4e961973-c030-449b-b54f-82f7e092350c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"large-scale irrigation schemes","subitem_subject_scheme":"Other"},{"subitem_subject":"small-scale irrigation schemes","subitem_subject_scheme":"Other"},{"subitem_subject":"roductivity","subitem_subject_scheme":"Other"},{"subitem_subject":"rice farming","subitem_subject_scheme":"Other"},{"subitem_subject":"Senegal river valley","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"On the Determinants of High Productivity Rice Farming in Irrigated Areas in Senegal: The Efficiency of Large Compared with Small-Scale Irrigation Schemes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the Determinants of High Productivity Rice Farming in Irrigated Areas in Senegal: The Efficiency of Large Compared with Small-Scale Irrigation Schemes"}]},"item_type_id":"6","owner":"3","path":["595"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-04-23"},"publish_date":"2015-04-23","publish_status":"0","recid":"757","relation_version_is_last":true,"title":["On the Determinants of High Productivity Rice Farming in Irrigated Areas in Senegal: The Efficiency of Large Compared with Small-Scale Irrigation Schemes"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T17:44:05.323231+00:00"}
