Outline of Final Research Achievements

In the present study, the yield gap was estimated for each municipality producing rice between 1994 and 2016 basically following the protocol in the international project named "The Global Yield Gap Atlas (GYGA)". The procedure of estimating the yield gap was to subtract the actual yield collected on municipality level as a part of statistical information released by the Ministry of Agriculture, Forestry and Fisheries from the potential yield defined by two major climate factors, i.e. solar radiation and temperature. Statistical analysis was conducted to find out climatic and socioeconomic factors affecting the actual yield and the yield gap differently for regions.

Academic Significance and Societal Importance of the Research Achievements

GYGAプロトコルに基づく収量ギャップは、収量の改善余地ないし未到達の作物生産能力をあらわす。本研究で実施した水稲の収量ギャップの推定は、わが国における市町村別収量データを用いた初めての試みであり、得られた推定値ならびにその要因をめぐる解析結果は農業政策立案に関する意思決定を行う際の基礎データとして活用することが出来る。
