Inland water resources and limnology in Indonesia
Indonesia has a vast area of inland waters, consisting mainly of lakes, Reservoirs, rivers and swamps. There are an estimated 14 million ha of inland waters, consisting of 220 significant rivers, 50 big lakes and reservoirs, all over the country. The high population density and rapid development in all sectors has raised a lot of environmental issues, including those inland waters. The increasing demand for space, food, water and industrial products, forces Indonesia to its utilization of inland waters. The utilization of inland water resources creates some problems, such as water pollution, siltation, eutrophication and the spreading of aquatic weeds and decreasing of indigenous species. Limnological on Indonesia is still limited. Due to the large extent of inland waters in Indonesia, the have not been studied entirely. Many inland waters have been researched, however data has not been compiled to allow to the construction of an environmental information system, which is crucial to balance development and conservation of inland water resources.
