Water pollution and eutrophication are becoming manifest in Japan's closed water areas, such as agricultural reservoirs, lakes, and marshes, as well as in coastal, shallow water areas. This is due to the increased amount of industrial and residential water discharge that has arisen both from the growing use of agricultural chemicals and chemical fertilizers as well as from the progressive urbanization of Japan's agricultural regions since the 1970s. The problem is even more serious in the developing countries of Southeast Asia, where, according to our investigations in northern Vietnam, water pollution is spreading rapidly into agricultural and closed water areas. Due to a serious deterioration in the water environment, developing countries are on the verge of experiencing the same rapid water contamination in their agricultural areas as Japan experienced since the 1970s. Urgent measures are needed in these countries to protect water environments in downstream closed water areas and to reduce the contamination load discharged from land areas, while sustaining high agricultural productivity.

Meanwhile, the environment of the watersheds is formed by material flow systems that reach closed, inner basins located anywhere between land areas upstream and downstream. Therefore, in order to protect the water quality in such regions, it is necessary to formulate an integrated management approach that comprehensively oversees the water and material recycling systems for watershed areas, including both land and sea.

This project aims to develop integrated watershed environment management tools, tailored specifically to the Red River Watershed in the northern Vietnam and the Mekong River Watershed in the southern Vietnam, both of which are subject to serious water pollution. Another aim of this project is to form a center for research and education pertaining to watershed environments in collaboration with staff at the Hanoi and Ho Chi Minh City campuses of Water Resources University, which is under the administration of the Ministry of Agriculture and Rural Development.

Research into watershed environment management encompasses a diverse range of areas, including upstream agricultural and forestry areas, middle- to downstream agricultural and industrial regions on the outskirts of urban areas, as well as closed water areas, rivers, irrigation and drainage canals, and coastal shallow water areas. Investigation into more extensive research tools for water, soil, meteorological, botanical, and other environments is also undertaken as part of watershed environment management. This project is conducted primarily by researchers in the Faculty of Agriculture at Kyushu University and the Institute of Tropical Agriculture at Kyushu University, with full support provided by the Research Institute for East Asia Environments at Kyushu University.
