Discussion between countries/regions in similar geologicaland meteorological condition will provide more improved
technology for rich river environment restoration.

Summary of Discussion in the Session on WWF4
River restoration is of vital importance to socio-economic sustainable
development in parallel with flood and water use management.
Basin is a basic unit for river environment management.
Establishing suitable methodological technology for river restoration thatsuit for Asian monsoon region is necessary.
In Asia monsoon region,g , human-influence to a cultural landscapep isharmonized with the ecosystem traditionally.
It is important to develop a database of projects and knowledge ofinternational experts in river restoration, and this activity should be
supported by engineers, scientists, ecologists, managers and public.
It is urgent to establish a river restoration guideline suitable for the Asianmonsoon region for countries with similar social and natural conditions.
