Outline of Final Research Achievements

A study area was set up in the lowland of Bangladeshi floodplain where rice cultivation and inland fishery were thriving, to conduct environmental engineering researches. Observations and computational approaches have revealed hydro-environmental dynamics in the study area. Field studies were conducted to clarify conflict and coexistence relationship between rice cultivation and inland fishery. It was expected that introducing groundwater into a fish pond during cool fallow season from December to January would raise the water temperature promoting faster growth of juvenile fish, and its feasibility study was implemented. In addition, several mathematical models were constructed for water quality management and optimal biological production in general.

Academic Significance and Societal Importance of the Research Achievements

対象地区における観測と調査の結果,不圧帯水層は地域のコモンズである一方,人口貯水池の所有と管理は基本的に個人で行われていることが明らかとなった。とくに,養魚の生産性向上のため,有機物の投入,ポンプによる給水や排水,てぐす張りによる鳥類からの食害防止,水田との連結などの工夫がなされている場合が数多く見られた。農閑期に地下水を養魚池に導入することは,十分に実行可能であることは明らかとなったが,経済的に有利となるとは結論できなかった。
