Abstract
Background
High-yielding variety (HYV) seed breeding has been one key approach to improving agricultural productivity and to reduce global hunger and poverty. This paper explores the causal relationship between high-yielding rice variety, rice productivity, farm income and household nutrition. A challenge with evaluating the impact of changes such as crop varieties on yield is self-selection and endogeneity. This article robustly identifies marginal input contributions, correcting for self-selection potential by applying matched Difference in Difference method.
Results
We found that the farms that switched from local to HYV, experienced around 35% higher yield and 76% higher profit from Aman rice than non-adopting farms. More calorie intake, more protein and especially higher fruit and vegetable intake meant less calorie poverty for adopted households.
Conclusion
This recent evidence suggests improved seed remains a high potential return investment for regions of the world where smallholder farming and malnutrition is a wider phenomenon.
