人们普遍认为，农业将有助于发展中国家农民的粮食安全和营养。然而，直接探索农业生产力和农民摄入微量营养素之间联系的研究很少。在这篇文章中，我们通过探索农业生产影响饮食结果的两个关键渠道来填补这一缺口：食物消费途径和现金收入途径。为了实现这一点，我们使用了马达加斯加Vakinankaratra地区收集的三年水稻种植者的面板数据。结果表明，尽管观察到的弹性很低，但水稻产量与农民的卡路里和微量营养素摄入量呈显著正相关。其次，提高水稻产量不仅对稻米消费有积极的显著影响，而且对稻米销售的产量份额和现金收入也有积极的显著影响。最后，研究结果表明，从大米销售中获得较高现金收入的家庭购买更多营养食品。因此，我们得出结论，市场代表了增加水稻产量转化为改善微量营养素摄入量的渠道。这项研究的结果表明，为了通过农业生产改善农户的营养，以提高产量为目标的干预措施应该伴随着市场准入措施。
It is widely expected that agriculture would contribute to farmers’ food security and nutrition in developing countries. However, studies that directly explore the link between agricultural productivity and micronutrients intake by farmers are scarce. In this paper, we contribute to filling this gap by exploring two key channels by which agricultural production can influence dietary outcomes: a food consumption pathway and a cash revenue pathway. To achieve this, we used three-years panel data of rice farmers collected in the Vakinankaratra region of Madagascar. The results suggest that rice yield is positively and significantly associated with farmers’ calorie and micronutrients intake, though the observed elasticities are low. Secondly, raising rice yield has a positive significant impact not only on rice consumption but also on the share of the output sold and the cash revenue from rice sales. Lastly, the results suggest that households with higher cash revenue from rice sales purchase more nutritious foods. Therefore, we conclude that the market represents the channel through which increased rice yield translates into improved micronutrient intake. The findings of this study imply that in order to improve farm households’ nutrition through agricultural production, interventions that target yield enhancement should be accompanied by market access measures.
