*1 Integrated Water Resource Management (IWRM)

IWRM aims at (1) giving integrated consideration to all forms and stages of the hydrological cycle in the natural system (such as land and water, water quantity and quality, surface water and groundwater), (2) giving consideration to a cross-sectoral approach among various sub-sectors related to water (river/flood control, water supply and sewage, and (3) a participatory approach including all levels of stakeholders such as the central government, local governments, the private sector, NGOs and inhabitants. Finally by managing water through such co-ordinated methods, it aims to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of the vital ecosystems.
