To explore this possibility, we analyze how triple rice cropping correlates with input use, productivity, and profitability in the Vietnamese Mekong Delta. We construct a new pooled cross-sectional dataset of representative rice farmers from 2006 to 2012, using a satellite imagery panel of commune-level rice cropping patterns from 2001 to 2012. Our empirical analysis controls for district and province-year fixed effects and finds that triple cropping continued for 4 years or more is correlated with increased chemical fertilizer costs. However, we do not find any negative effects on rice yield, rice income per hectare, farm income, or household income. Based on our results,we discuss policies to improve the environmental sustainability of rice production.","subitem_description_type":"Abstract"}]},"item_14_geolocation_18":{"attribute_name":"地域/国名","attribute_value_mlt":[{"subitem_geolocation_place":[{"subitem_geolocation_place_text":"Vietnam"}]}]},"item_14_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Developing Economies　(IDE-JETRO)"}]},"item_14_rights_5":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyrights 2023 by author(s)"}]},"item_14_subject_17":{"attribute_name":"JEL分類","attribute_value_mlt":[{"subitem_subject":"JEL:O13 - Agriculture • Natural Resources • Energy • Environm...","subitem_subject_scheme":"Other"},{"subitem_subject":"JEL:Q12 - Micro Analysis of Farm Firms, Farm Households, and ...","subitem_subject_scheme":"Other"},{"subitem_subject":"JEL:Q56 - Environment and Development • Environment and Trade…","subitem_subject_scheme":"Other"}]},"item_14_text_32":{"attribute_name":"著者別名","attribute_value_mlt":[{"subitem_text_value":"塚田,和也"},{"subitem_text_value":"荒神,衣美"}]},"item_14_version_type_15":{"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":"Tsukada, Kazunari"}],"nameIdentifiers":[{"nameIdentifier":"63470","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arimoto, Yutaka"}],"nameIdentifiers":[{"nameIdentifier":"63471","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kojin, Emi"}],"nameIdentifiers":[{"nameIdentifier":"63472","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mano, Yukichi"}],"nameIdentifiers":[{"nameIdentifier":"63473","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Lan, Nguyen Kim"}],"nameIdentifiers":[{"nameIdentifier":"63474","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":"2023-05-18"}],"displaytype":"detail","filename":"IDP000899_001.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Full-text PDF","url":"https://ir.ide.go.jp/record/53752/files/IDP000899_001.pdf"},"version_id":"87176d54-e123-4bd6-9ada-5de5b14e66f5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Triple rice cropping","subitem_subject_scheme":"Other"},{"subitem_subject":"sustainability","subitem_subject_scheme":"Other"},{"subitem_subject":"Mekong Delta","subitem_subject_scheme":"Other"},{"subitem_subject":"Vietnam","subitem_subject_scheme":"Other"},{"subitem_subject":"Rice","subitem_subject_scheme":"Other"},{"subitem_subject":"Agricultural innovations","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Cumulative Effects of Intensified Cropping Cycles: Triple Rice Cropping in the Vietnamese Mekong Delta","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cumulative Effects of Intensified Cropping Cycles: Triple Rice Cropping in the Vietnamese Mekong Delta"}]},"item_type_id":"14","owner":"3","path":["5564"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-05-18"},"publish_date":"2023-05-18","publish_status":"0","recid":"53752","relation_version_is_last":true,"title":["Cumulative Effects of Intensified Cropping Cycles: Triple Rice Cropping in the Vietnamese Mekong Delta"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T13:45:28.843258+00:00"}
