The eutrophication of Lake Biwa, the most important water resource in Japan, has focused national and international attention on the need for integrated land and water management within the context of the Catchment Ecosystem. An exceptional rate of economic growth since 1954 coupled with a lack of awareness of the relationships between human activities and water quality led to the rapid pollution of the lake. The control of industrial point-sources of pollution failed to reduce the pollution loads of nitrogen and phosphorus entering the lake which were found to be dominated by domestic effluents. These latter represent quasi non-point sources and in a country where sewage treatment facilities are sparse, water management has developed through active public cooperation. River loadings have been controlled by a set of well co-ordinated activities influencing industrial location, modes of production and life-style, and including water treatment measures, land use controls and environmental education. However, once established, the recycling of nutrients within a lake can cause management problems for tens of years and for integrated river basin management to be effective an anticipatory approach must be developed.
