In a case study of inland valleys in central Nigeria, we investigated the farming strategy of Nupe farmers who have a long-term tradition of wet rice cultivation and indigenous methods of land preparation for soil, water and weed management. In this region, a new method of land preparation has recently been introduced along with a recommendation to use improved seeds and chemical fertilizers. Our findings reveal that Nupe farmers directly sow traditional seeds and apply a marginal amount of fertilizer to paddy plots prepared by labor-saving methods on drought-prone hydromorphic valley fringes and flood-susceptible valley bottoms, whereas they preferentially transplanted improved seedlings and applied a relatively large quantity of fertilizer to paddy fields prepared by a labor-intensive and mechanized method on a valley position where they can access to optimum water condition (less risky against the drought and flood).","subitem_description_type":"Abstract"}]},"item_14_geolocation_18":{"attribute_name":"地域/国名","attribute_value_mlt":[{"subitem_geolocation_place":[{"subitem_geolocation_place_text":"ナイジェリア"}]}]},"item_14_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20561/00037814","subitem_identifier_reg_type":"JaLC"}]},"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 日本貿易振興機構（ジェトロ）アジア経済研究所 / Institute of Developing Economies, Japan External Trade Organization (IDE-JETRO) http://www.ide.go.jp"}]},"item_14_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_14_subject_17":{"attribute_name":"JEL分類","attribute_value_mlt":[{"subitem_subject":"JEL:N57 - Africa;
