This report contains the assessments of availability and use of aquatic organisms in rice ecosystems conducted in late 2013 in four sites in Indonesia. The documentation was made of the animal and plant organisms found in the study sites and being collected by the people, the methods and tools to capture or gather them, and their uses as food, medicine and for other purposes. Local people have generally acknowledged a general decline in the abundance and diversity of the species. Factors included the intensification of rice cultivation accompanied by the use of chemical inputs, increasing exploitation driven by population increase and in some cases a high market demand for some species, and destructive fishing.
