| Outline of Final Research Achievements |
In SSA, the platform for rice growing environment, "sawah", and its product, "paddy", are described by the same word paddy. This is an obstacle to scientific development of rice farming. Sawah ecotechnology to improve rice growing platform and biotechnology to improve seed are equally important. Through the dissemination of sawah technology, Kebbi farmers have developed portable pump irrigated sawah platform by their self-help efforts (endogenously) in the floodplains and deltas of the Rima River and the Niger River since 2011. Sawah Technology can be spread not only Kebbi, but also to the floodplains, inland deltas and numerous small inland valleys throughout Nigeria and the West African countries within the next decade or so. Furthermore, looking at the future several decades, the Sahel belt areas around Lake Chad and South Sudan has similar ecological environment to the Nile Delta and the Deccan Plateau of India, and has the potential to become the core rice cultivation zone of SSA.

| Academic Significance and Societal Importance of the Research Achievements |
SSAでは稲の生育環境,水田と生産物,籾がpaddy一語で混同されているため、水田稲作発展の阻害要因となっている。水田(Sawah)の改良進化を実現するエコテクノロジーと品種改良技術はSSAの水田稲作発展の車の両輪である。アフリカ水田農法(Sawah Technology)は、Kebbi州の氾濫原のみならず、今後10数年以内にナイジェリア全土と西アフリア諸国の氾濫原や内陸デルタ及び内陸小低地に普及可能である。さらに、数10年後を展望すれば、チャド湖周辺や南スーダン等のサヘル帯は、ナイルデルタやインドのデカン高原のバーテソル地帯と生態環境が類似し、SSAの中核的稲作地帯になるポテンシャルがある。
