How to make farming and agricultural extension more nutrition-sensitive: evidence from a randomised controlled trial in Kenya
通过肯尼亚的随机对照试验，研究了农业推广如何更有效地促进农民采用生物强化作物等营养敏感型技术，发现强化农业培训能显著提高采用率，而额外营养培训则进一步帮助农民认识营养益处。
We analyse how agricultural extension can be made more effective in terms of increasing farmers’ adoption of pro-nutrition technologies, such as biofortified crops. In a randomised controlled trial with farmers in Kenya, we implemented several extension treatments and evaluated their effects on the adoption of beans biofortified with iron and zinc. Difference-in-difference estimates show that intensive agricultural training can increase technology adoption considerably. Additional nutrition training helps farmers to better appreciate the technology’s nutritional benefits and thus further increases adoption. This study is among the first to analyse how improved extension designs can help to make smallholder farming more nutrition-sensitive.
