途上国農家の技術採用においては，他人の知識や経験から学ぶ社会的学習を踏まえた行動介入の効果検証が近年急速に展開され，科学的知見が積み上がりつつある．これらの研究は，農家による技術の新規採用行動に焦点を当てており，短期的な観点から行動介入の設計と効果の検証が行われてきた．しかし開発の持続可能性を考慮した環境保全型農業技術の採用においては，短期的な観点のみならず，いかにその採用行動の継続を促すかといった長期的な観点からの行動介入の設計とその効果の検証が強く求められる．そこで本研究では，途上国の小規模農家に環境保全型農業技術の長期的な採用を促すために，社会的学習を踏まえた行動介入の長期効果や，その介入効果を維持・増進させるための社会的コミットメント・メカニズムの併用効果を，フィールド実験手法を用いて明らかにする．この研究目的を達成するために，次のような5つの主要な研究課題を設定した．[1]2018 年に行ったフィールド実験研究の追跡調査，[2]ベースライン調査と介入の無作為割当，[3]フィールド実験における介入開始，[4]短期フォローアップ調査，[5]長期フォローアップ調査2022年度は，[1]，[2]に主眼を置いた研究活動を実施した．具体的には，現地における茶生産農家の家計行動調査を2022年11－12月にかけて行い，行動介入の基礎となるデータベースを構築した．また同時に，各農家の農地の土壌検査を行い，土壌の劣化状況に関する科学的結果を農家に知らせることが，彼らの有機肥料導入・使用を促進するかという行動介入フィールド実験のパイロットを実施した．今後は得られた予備的結果を精査し，本実験のデザインを調整，最終化する予定である．

On the way to the national farmers' technical equipment, others know that the students of the society are involved in the activities of the society. As a result, the knowledge of science has been expanded rapidly in recent years, and scientific knowledge has been actively studied. The focus of the new regulations on technology and technology has become an important focus. Short-term intervention of environmental protection in agricultural technology, short-term environmental protection, environmental protection, environmental protection On the way to the national small-scale model farmers' long-term environmental protection agricultural technology training program, the national small-scale model farmers' long-term environmental protection agro-technical training program is on the way to the national small-scale model farmers' long-term environmental protection agro-technical training program, and the social science training program is involved in the long-term environmental protection agricultural technology training program. The purpose of this study is to improve the quality of the society. [1] in 2018, the main research topics are set up. [1] in 2018, the main research topics are set up. [1] in 2018, the main research project settings. [2] due to the failure of intervention, [3] the beginning of intervention, [4] short-term health care, [5] long-term health care in 2022, [1], [2] major research activities have been implemented. The farmers of the land and rural areas planned to conduct activities from November to December of 2022, and the actions were involved in the basic agricultural activities. At the same time, the farmers in the same period, the farmers in the rural areas, the agricultural land and the poor condition of the soil, the results of the science, and the farmers knew the results of the science. The other party has the opportunity to apply fertilizer to promote the use of information technology to facilitate the operation of the equipment. In the future, we have obtained the results of the equipment. We have obtained the results of the operation. The results show that the system is in good condition.
