After deforestation, it is often difficult to sustain annual crop production since nutrients are rapidly leached from the soil due to high rainfall in the tropics. There are several sites and systems of agroforestry where agriculture is combined with forestry to provide food and wood without causing a degradation of the ecosystems in the Philippines. We investigated sites where agroforestry is applied using sloping agriculture land technology in Ilocos Norte and multistoried cropping systems in Cavite in 1991. Although the topography of these sites was different, the common feature was the emphasis placed on soil and water conservation as well as on soil fertility maintenance using trees and crops at the same time and sequentially, since these were the major factors affecting further development and sustainability of the upland areas.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"イロコスノルテ州の実践地では土壌保全のため等高線上に早生樹のカカワテが帯状に植栽され，その間に陸稲，豆類及び野菜が輪作されていた。カビテ州では上層にココナツ，下層にカカワテ，パパイヤ，コーヒー，バナナ，パイナップル，サトイモなどが連続的に植栽され，空間の高度利用が行われていた。これらの地域の地形は傾斜地と平坦地とそれぞれ異なるが，どちらの技術も同時あるいは連続的に林木と作物を植栽することによって土壌の肥沃化や土壌保全化が図られ持続的農業を担っている点で共通していた。\n一方でアグロフォレストリーの研究は，まず実行形態を把握し，社会的背景の究明や経営·経済的な分析が不可欠である。これには農業や林業における様々な研究分野に跨ることから，多くの分野の専門家が協力して研究を進めていくことが重要になる。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available"}],"filename":"jircas_journal6-_83-88.pdf","filesize":[{"value":"1.18MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_journal6-_83-88","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000163/files/jircas_journal6-_83-88.pdf"},"version_id":"2182b7e3-947b-42cd-9524-dcb679eb6046"}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000163","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan International Research Center for Agricultural Sciences","subitem_publisher_language":"en"}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"13407686","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AA11030483","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"agrisilviculture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"soil erosion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"multistoried cropping system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sloping agriculture land technology","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Introduction of Agroforestry in the Philippines","subitem_title_language":"en"},{"subitem_title":"フィリピンにおけるアグロフォレストリーの紹介","subitem_title_language":"ja"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"Introduction of Agroforestry in the Philippines","item_type_id":"40039","owner":"8","path":["1705364364835"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-03-13"},"publish_date":"2024-03-13","publish_status":"0","recid":"2000163","relation_version_is_last":true,"title":["Introduction of Agroforestry in the Philippines"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2024-03-13T04:31:01.198929+00:00"}
