日本の農水産業におけるエネルギー消費の実態

タイトル（英文）

ACTUAL ENERGY CONSUMPTION BY AGRICULTURE ANDFISHERYIES IN JAPAN

概要 （図表や脚注は「報告書全文」に掲載しております）

農水産業の省エネルギー化に資するため，農業と漁業・養殖業におけるエネルギー消費の実態を調査し，省エネルギー化に必要な技術開発の要点を抽出した。〔エネルギー消費の実態〕農業では，平成２年の農家一戸当たりの平均消費量は，昭和５５年に比較し，２７％増加した。増加が著しいのは，軽油，電力，農業薬剤，飼料および肥料であった。漁業・養殖業では，平成３年の単位生産量あたりの消費量は，昭和５３年に比較し，遠洋・沖合漁業が８％，沿岸漁業が１９％，海面養殖が１７％増加した。〔省エネルギー技術開発の要点〕農業では，暖房用の重油，肥料，飼料および農業薬剤の節減である。沿岸漁業と養殖業では，船舶燃料と海水■み上げ電力の節減および飼料への投入エネルギーの節減である。

概要 （英文）

CREATION OF AN ENERGY-SAVING SOCIETY IS AN URGENT NECESSITY. HOWEVER THERE ARE MANY UNCLEAR POINTS IN THE ACTUAL CONDITIONS OF JAPANESE AGRICULTURE AND FISHERIES. THIS STUDY INVESTIGATEDACTUAL ENERGY CONSUMPTION IN AGRICULTURE AND FISHERIES,AND EXTRACTED THE KEY TECHNICAL DEVELOPMENTS NECESSARY FOR SAVING ENERGY. 1.AGRICULTURE THE ENERGY CONSUMPTION PER FARM IN 1990 WAS 44.7X10E6 KCAL,27% UP OVER 1980.OIL ELECTRICITY,AGRICULTUAL CHEMICALS,FEED AND FERTILIZER CONSURPTION INCREASED SIGNIFICANTLY BY 63% 58% 45% 41% AND39%,RESPECTIVELY. THE KEY POINT IN ENERGY-SAVING SHOULD CONSIDER REDUCTION OF HEATING OIL.TNCREASED ELECTRICITY DEMAND WITH AUTOMATION AND HIGH-TECHNOLOGY CAN NOT BE AVOIDED,SO EFFECTIVE USE AND LOAD SHIFTING TO NIGHT ARE NECESSARY.FURTHER,MOVE REDUCTION OF FERTILIZER,FEED AND AGRICULTURAL CHEMICALS IS IMPORTANT.TO DECREASE THE IMPACT OF AGRICULTURAL CHEMICALS AND FERTILIZERS ON THE ENVIRONMENT,TECHNIQUES TO PREVENT OUTFLOW TO THE ENVIROMENT ARE RECESSARY. 2.FISHERIES AND AQUACULTURE CONSUMPTION IN 1991 WAS 73,400X10E9 KCAL,ABOUT 5% OVER 1978. CONSUMPTION BY DEEP-SEA OFFSHORE FISHERIES DECREASED WHILE THAT OF THE COASTAL FISHERIES AND SEA-SURFACE AQUACULTURE INCREASED.THE CONSUMPTION YIELD IN 1991 FORL THE ABOUT THREE ITEMS INCREASED BY 8%,19% AND 17%,RESPECTIVELYCONSUMPTION OF BOAT FUEL IN INSHORE FISHERIES AND SEA-SURFACE AQUACULTURE,ELECTRICITY FOR PUMPING SEA WATER IN ON-SHORE AQUACULTURE,FEED IN BOTH SEA-SURFACE AND ON-SHORE AQUACULTURE INCREASED AND OCCUPIES A LARGE SHAVE ENERGY CONSUMPTION.REDUCTION OF BOAT FUEL,ELECTRICITY FOR PUMPING SEA WATER,AND ENERGY INPUT TO FEED IS NECESSARY.
