摘要

In the mountains of northern Vietnam, paddy rice plays a major role in the food security of most households. A survey of 300 households in the province of Bac Kan revealed the importance of mountain paddy rice in recent agrarian changes. Households' production strategies were found to develop according to two key factors: access to paddy fields (mountains, valleys, and terraces), and each household's rice self-sufficiency level. A multivariate statistical analysis helped explain the production relationships between mountain paddy rice, crop-livestock systems on the hillsides, and off-farm activities. When households lack paddy rice, they turn to upland rice on the hillsides, cattle and pig breeding, and off-farm activities to sustain their livelihoods. Households whose paddy rice requirements are met begin to diversify their production systems with cash crops and buffalo breeding. The analysis of production systems that have resulted from differing levels of rice self-sufficiency led to the development of a farming system differentiation model. An understanding of the different strategies in the regions studied makes it possible to target more precisely development interventions and technical and economic advice to farmers.
