英文文献摘要：
Despite the many potential benefits of legume cultivation, there is scarce empirical evidence on the effects of improved legume technologies on household food security and nutrition. This paper begins to fill that knowledge gap by empirically estimating the effects of adoption of cereal-legume intercropping and cereal-legume rotation on indicators of food security and nutrition for smallholder farm households in Zambia. The results indicate that cereal-legume rotation is positively and statistically significantly associated with household dietary diversity, months of adequate household food provisioning, and calorie and protein production, but is significantly negatively correlated with net crop income. In contrast, we find little evidence of statistically significant cereal-legume intercropping effects on the food security and nutrition status of Zambian smallholder farm households.
