Crop\nproduction is largely characterized by smallholder subsistence farmers who depend solely on highly\nunpredictable and irregular seasonal rainfall. In recent times, rainfall variability has led to numerous\nincidences of drought and floods. This phenomenon has the potential to adversely affect crop production and\nfood security in the area. This study analyses inter- and intra-annual variability of rainfall so as to identify\nthe relationship between rainfall variability and crop production in a representative district of Northern\nGhana. Available monthly rainfall data for 33 years (1980 - 2012) recorded at Babile station of the district\nwas analyzed for seasonal and annual variability using the coefficient of variation (CV) and the precipitation\nconcentration index (PCI). Total annual quantity of crop production data on main crops (i.e. maize, millet,\nsorghum, groundnut and cowpea) was used. The available data covered a period of 21 years (1992 - 2012).\nTo verify the influence of rainfall variability on crop production, correlation analysis was conducted.\nAlthough the results showed moderate seasonal rainfall distribution, (i.e. PCI\u003e11), the inter-seasonal and\ninter-annual rainfall variability (CV=0.19 and C=0.18 respectively) were moderate/less erratic. The results\npoint to a negative correlation between annual rainfall and crop production for maize, millet, sorghum,\ngroundnut and cowpea. At seasonal level sorghum, millet and groundnut showed negative correlation while\nmaize and cowpea showed positive correlation. These results also point to a need for further studies to\ndetermine the influence of rainfall on arable land use and the periods of occurrence of drought in the study\narea. The results of this study would enable farmers to improve their crop production strategies.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_36": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Society for Social Management Systems"}]}, "item_5_version_type_19": {"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": "NDAMANI, Francis"}], "nameIdentifiers": [{"nameIdentifier": "3376", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "WATANABE, Tsunemi"}], "nameIdentifiers": [{"nameIdentifier": "3377", "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": "2019-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "sms13-9480.pdf", "filesize": [{"value": "134.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 134800.0, "url": {"label": "sms13-9480.pdf", "url": "https://kutarr.kochi-tech.ac.jp/record/1257/files/sms13-9480.pdf"}, "version_id": "286170e0-4b3d-45fc-a6b5-f2cb0139d06e"}]}, "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": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "RAINFALL VARIABILITY AND CROP PRODUCTION IN NORTHERN GHANA: THE CASE OF LAWRA DISTRICT", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "RAINFALL VARIABILITY AND CROP PRODUCTION IN NORTHERN GHANA: THE CASE OF LAWRA DISTRICT"}]}, "item_type_id": "5", "owner": "2", "path": ["25"], "permalink_uri": "http://hdl.handle.net/10173/1261", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-02-28"}, "publish_date": "2015-02-28", "publish_status": "0", "recid": "1257", "relation": {}, "relation_version_is_last": true, "title": ["RAINFALL VARIABILITY AND CROP PRODUCTION IN NORTHERN GHANA: THE CASE OF LAWRA DISTRICT"], "weko_shared_id": -1}
