| Outline of Research at the Start |
本研究は，わが国の有機農業を推進していくためには，どのような補助政策（環境農業直接支払い）が有効であるかを調査する．農業経営における生産活動の効果を経済面と環境面の両方について数式化したバイオエコノミックモデルを作成し，それを用いて現在の補助政策の改善シナリオを検討する．

| Outline of Final Research Achievements |
The present study examined whether organic rice was cultivated in Japanese rice farms under the direct payments for environmentally friendly agriculture. A bio-economic farm model with an economic objective function to be maximized and environmental objective functions to be minimized was built in the analysis. The environmental objective functions were made using the results of life cycle assessment. The results of multi-objective optimization show that organic rice production may be limited because it increases crop income but does not necessarily mitigate environmental impacts. Finally, improvements in the direct payments for environmentally friendly agriculture were suggested.
