バングラデシュにおける飲料水ヒ素汚染災害の軽減に関する研究

Abstract

バングラデシュにおけるヒ素汚染問題に関して，先行研究により，ヒ素汚染被害軽減のためには住民の水運びの負担を軽減することが重要であると認識した。本研究ではこのような認識のもと，現地調査（村の地図の作成，ヒアリング）を行い，これらをもとに，「安全な飲料水に対する欲求度」及び「水運びストレス」という2つのモデルを構築する。そしてこれらのモデルを用いることによって，住民の水運びに着目したヒ素汚染災害軽減のための計画プロセスを示す。

In Bangladesh there are many disasters, such as floods, droughts, and hurricanes; moreover in recent years, arsenic contaminated drinking water has become one of their major problems. Long term effects of drinking arsenic contaminated water include illness, possible cancer, and in the worst case, death. Because of the economic problem in Bangladesh, the effective prevention of arsenic contamination can not be conducted. From our previous study which includes the survey and analysis, the burden of carrying drinking water is one of the most serious issues for local people. In this study, based on the recognition from the previous study, the social investigation in a village is carried out again, and the models related their burdens of carrying water are suggested.
