In the San Jose District, which is designated as the model project site, the permeability of the soil in the upland areas was extremely poor at a saturated hydraulic conductivity of the order of 10-8 cm/s and a basic intake rate of 0.1 mm/h attributable to the densely grained soil texture with few macro pores, whereas the permeability of the soil in the lowland areas was classified as medium to low level. The rainwater runoff was shown to differ conspicuously between the rainy and dry seasons, and the monthly and annual rainwater runoff rates were obtained. The amount of annual recharge in the shallow groundwater was estimated by the water balance method and the porosity method, based on which the amount of water stored in the shallow groundwater and reservoirs available as water resources for irrigation was estimated. These results will provide useful fundamental data for drawing up plans and designs when constructing new irrigation facilities in the future. Meanwhile, fruit trees and greenhouse vegetables were cultivated in the model fields where drip irrigation facilities were installed, based on which the amount of irrigation water required, the state of crop growth, and the yields of crop production were identified. Eight farming households in the San Jose District constructed drip irrigation facilities in their orchards with financial support from the Instituto de Desarrollo Agropecuario (INDAP: Institute of Agricultural Development) which provided the farmers with advance loans for construction. The breakdown and the ratios of construction expense items incurred were identified, and a method for mitigating the burden on farming households in return for their labor was established.\nThese results will provide farming households with a strong incentive for constructing irrigation facilities in the future. To follow the model case of the San Jose District for promoting agriculture in the inland arid regions, the Ministerio de Agricultura (MINAGRI: Ministry of Agriculture) of Chile needs to take the following actions.\n1) To implement an agricultural development project covering the entire San Jose District, plans for land use, irrigation farming, and the construction of irrigation facilities for the respective groups of 10 to 20 farming households, each group sharing the same single watershed, should be drawn up jointly with the departments in charge of farming and cultivation systems and soil management.\n2) A comprehensive method for exploiting water resources, including the surface runoff water, shallow groundwater, and deep (bedrock) groundwater, should be developed.\n3) The precision of estimating the water storage at source should be improved by prospecting the deep groundwater and conducting hydrological surveys on a routine basis.\n4) An irrigation management method for producing high quality crops should be developed.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"チリ共和国政府は，全人口のほぼ1/3にあたる低所得者層の経済的自立を，重要政策課題の一つとして掲げている。この低所得者層は，チリ中央部の南緯32度～37度にわたる第５州から８州までの内陸乾燥地で，天水農業を行っている農村部に多く居住している。チリ政府は，対象とする天水農業地帯に，水と土壌保全を踏まえた灌漑技術を導入し，この条件を生かした栽培作物の多様化と高品質生産によって，農業収入の増大を図る基本政策を策定した。この事業計画の立案と実施，普及に至るまで一連の技術移転を，住民参加型手法によって行う体制整備を目的として，1997年３月，我が国へ技術協力の要請を行った。\nこれをうけて，2000年３月より2005年２月までの５カ年計画で，国際協力事業団（JICA）のプロジェクト方式技術協力「チリ住民参加型農村環境保全計画（CADEPA）」が開始された。プロジェクトのタイトルにある環境保全の内容は，利用可能水量の増大による水資源開発と侵食防止農法を中心とした土壌保全技術の開発である。\n筆者は，本プロジェクトの灌漑・水資源の長期専門家として，2000年３月から３年間，首都サンチアゴ市から南へ約400kmのチジャン市に所在するチリ農業省キラマップ農牧研究所（INIA）に派遣された。ここで，CADEPAの活動のうち，水資源開発と灌漑施設整備について調査を行ったので報告する。\nなお，本調査の実施に際して，カウンターパートINIA研究員Hamil URIBE， Octavio LAGOS， HaraldWAGEMANNの３氏，JICA長期専門家の眞鍋　糺氏（前高知県果樹試験場），短期専門家として現地に来られた緑資源公団小林　勤調査役，奥田幸夫課長，成岡道男係長から御協力を頂いた。ここに深く感謝の意を表する。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_12_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/0002000051","subitem_identifier_reg_type":"JaLC"}]},"item_12_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人農業工学研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"NATIONAL INSTITUTE FOR RURAL ENGINEERING INDEPENDENT ADMINISTRATIVE INSTITUTION","subitem_publisher_language":"en"}]},"item_12_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-3314","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"太田, 弘毅","creatorNameLang":"ja"},{"creatorName":"オオタ, コウキ","creatorNameLang":"ja-Kana"},{"creatorName":"OTA, Koki","creatorNameLang":"en"}],"familyNames":[{"familyName":"太田","familyNameLang":"ja"},{"familyName":"オオタ","familyNameLang":"ja-Kana"},{"familyName":"OTA","familyNameLang":"en"}],"givenNames":[{"givenName":"弘毅","givenNameLang":"ja"},{"givenName":"コウキ","givenNameLang":"ja-Kana"},{"givenName":"Koki","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"11303","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":"2024-02-28"}],"displaytype":"detail","filename":"TRNIREJ202_1-17.pdf","filesize":[{"value":"273 KB"}],"format":"application/pdf","license_note":"©　 国立研究開発法人 農業・食品産業技術総合研究機構\nNational Agriculture and Food Research Organization, Japan","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://repository.naro.go.jp/record/2000051/files/TRNIREJ202_1-17.pdf"},"version_id":"aa52b2ee-1aea-4b73-b2d7-139b71c426e0"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"チリ共和国内陸乾燥地における水文調査と灌漑施設整備 －住民参加による水利施設整備の負担事例－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"チリ共和国内陸乾燥地における水文調査と灌漑施設整備 －住民参加による水利施設整備の負担事例－","subitem_title_language":"ja"},{"subitem_title":"Hydrological Surveys and Construction of Irrigation Facilities in Inland Arid Regions of the Republic of Chile － A Case Study of Cost-Sharing Construction of Hydraulic Structures by Public Participation －","subitem_title_language":"en"}]},"item_type_id":"12","owner":"12","path":["1707895637859","1"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-02-28"},"publish_date":"2024-02-28","publish_status":"0","recid":"2000051","relation_version_is_last":true,"title":["チリ共和国内陸乾燥地における水文調査と灌漑施設整備 －住民参加による水利施設整備の負担事例－"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2024-08-07T23:57:38.786284+00:00"}
