| Summary: | Integrated crop-animal systems are important in Asia. Both ruminants and non-ruminants are used in a variety of combinations with annual and perennial crops in Indonesia, the Philippines, Malaysia, China and Sri Lanka. These combined systems provide distinct economic benefits, and are more compatible with ecological and environmental sustainability. Increased investment in these systems is likely and research is needed on feed resources, use of indigenous animal genetic resources and livestock disease to increase livestock production. In addition, available research results should be applied and enabling policies developed to promote increased investment in livestock production and natural resource use and management in the rainfed warm humid/subhumid and arid/semiarid tropics.
