Water Environment Crisis
The water environment crisis in Asia will be more
and more serious mainly because of rapid increaseof population and more rapid economic growth
mainly due to industrialization/urbanization.
Deterioration of water resources in quantity and inquality will certainly limit future achievement ofsustainable development. Domestic, industrial andagricultural demands are to be carefully adjusted
based upon the limitation of local renewable watersupply.
To cope with complex types of water environment
problems, cooperation among all the stakeholders isneeded so that integrated solution may be reached.

Water Environment Partnership in Asia(WEPA)Past activities of WEPA contributed to streamlining
various information among diversified member
countries. Water environment-related problems on
qualities/states, technologies, policies,
governmental/nongovernmental activities etc. havebeen identified, organized and archived.
Future step-up programs of WEPA are expected(1) to focus on solution findings for industrial and/or
domestic water and/or wastewater management, a(2) to strengthen local governance capabilities onwater environment control, and (3) to expand its
activities by involving private sectors in designingsustainable and appropriate water management
systems.
