Crop-livestock systems research in Asia : design and testing OFR

In recent years, the Network"s methodology has moved incrementally from a cropping systems to a farming systems focus. After describing the Network"s progress in research design, and noting the importance of livestock and increasing land constraints to smallholder production, the report analyzes three current, on-farm trials of crop-livestock systems - in the Philippines, Indonesia, and Thailand - taking both crop and animal production needs and objectives into consideration, describing research sites (e.g., rainfall patterns), and discussing methodology. A planning strategy for crop-livestock systems research is presented in outline form, identifying the system"s objectives, socioeconomic research studies, and biological research components (food crops, perennial crops, livestock, and mixed crop/livestock).
