Popis: The rapid specialization of livestock production contributes to spatially decoupled crop and livestock production. Relinking croplands and livestock to promote wastes and by-products exchange has been suggested to provide opportunities for sustainable intensification of agriculture systems. However, the environmental and economic performances of such crop-livestock systems remain highly context specific and unclear. This study proposed an emergy-LCA-based framework to study the GHG mitigation and ecological and economic benefits of the integrated crop planting and livestock feeding systems, by taking wheat maize rotation-swine systems (WMRS), tea-swine systems (TS) and citrus alfalfa intercropping-swine systems (CAIS) as the empirical cases. The results showed the three case modes can generally promote GHG mitigation and ecological and economic benefits. CAIS had the lowest carbon footprint per kcal product (0.12 g CO
