By enhancing the exchange of materials and energy between livestock and crop systems within and between farms, crop-livestock integration contributes to improving productivity, increasing the value of plant resources, maintaining soil fertility, and improving the sustainability of agricultural systems and territories. The Vietnamese agricultural systems, driven by public policies and private sector investments, have evolved rapidly with a strong intensification of production systems (use of mineral fertilizers, improved seed and breed, industrial feed, biosecurity). The fast intensification is combined with a specialization of farms and territories, along with the appearance of large intensive farms (industrial farming). These recent changes therefore raise the question of the future of crop-livestock integration in the development of the Vietnamese agricultural sector. The loss of crop-livestock integration practices will impact the sustainability of agricultural systems and the territories. This study aims to understand the trajectories and the main change regarding crop-livestock integration practices at the farm and beyond the farm level to understand the potential future of the integrated crop-livestock systems in the territory. Ði¿n Biên District (Province of Ði¿n Biên) is located in North-West Vietnam and presents a diversity of farming systems with a wide rice valley surrounded by mountainous massifs. The importance of bovo-bubaline livestock for the local economy, the land resources, and the ongoing changes in agriculture raise interest in the development of agriculture, and livestock in particular. A typology focusing on the 3 dimensions of crop-livestock integration (feed, fertilization, animal labour) has been developed based on previous work classifying farms according to the degree of feed intensification and crop-livestock integration. It distinguishes six groups of farms according to the orientation of their production (animal, crop) and the degree o
