Abstract
Malaysia has a climate of high humidity, high temperature and abundant rainfall. Rivers supply about 97% of the country's total water needs while ground water accounts for the rest. About 40% of the treated water is lost through man-caused leakages. With a population of 18.3 million people, the total annual domestic, industrial and irrigation water demand is about 11.6 x 106 MI. This figure is projected to rise to 15.2 x 106 MI by year 2000. At present, the total daily water demand is about 4,979 MI and the production capacity is 6,513 MI. Water use and misuse now strain the nation's fragile aquatic environment and natural ecosystems. Current water resource management priorities include water quality improvement, river rehabilitation to restore over-channalized or polluted rivers and development of the inland fisheries potential especially in large man-made reservoirs. A River Basin Information System has been developed to provide integrated information on catchment characteristics, landuse, population and socio-economic profile, river flow, pollution sources, water quality classification, and aquatic biota. Vision 2020 challenges call for a long-term perspective in inland water resource management. Critical post-audits of largescale development and strategic research aimed at alternative and interacting patterns of landwater use are urgently needed.
