Abstaract. This research was focused on the evaluation of functions of lowlands swamp ecosystem for food production, conducted in Pempangan sub district of Ogan Komering Ilir, South Sumatra Province. During rainy season the area’s of aquatic environment is suitable for fishing ground while during dry seasonthe area becomes rice field. Animal husbandry activities used the area as grazing field of swamp buffalo (kerbau rawa). Rice cultivation is only oe time a year with sequence activies begin with land clearing, collection of plant litter, growing rice seedling, wee control, and harvest. There were four variesties of rice cultivated in the area such as: Celiwung Serang, IR-42, and INPARA-3. Rice productivity was quite low (about 1 ton per ha per year) from the total areas of 11,070 ha paddy field. Integration of rice cultivation – fisheries – and animal husbandry within swamp area can increase fermer’s Income. In order to reach sustainable use of swamp esosystem, some management schemes should be practiced by balancing rate of exploitation with conservation of the resources.

Indonisia areas of lowland swamp is about 33 million hectares which were grouped into tidal and non tidal swamps. About 13,296,770 hectares area (39.8%) is categorized as non tidal swamp and only 341,526 hectares of which has been developed into agricultural land (Ditjen Pengairan Depertmen PU in Susanto 2010). Therefore, the swampland have potentials to develop in order to produce food. In South Sumatra Province, there were 1.1 million hectares non tidal lowlands swamp areas (Sumsel in figure 2005), whice are still under utilized.
Lowland swamp is a haif way world between terrestrial and aquatic ecosystem and exhibits some of the characteristics of aech (Smith 1980). Mitsch & Gosselink (1986) described that lowlands are distinguished by the presence of water, have a unique soils that differ from adjacent uplands, and support geowth of vegetations adapted to the wet condition. Zinn and Copeland (1982) defined although water is present for the least part the time, the depth and duration of flooding very considerably from wetland to wetland, and often at the margins between deep water and terrestrial uplands, and are influenced by both systems.
