进入安全,负担得起的饮食对于改善营养结果至关重要。然而,利益相关者如何看待有约束力的约束和必要的政策行动,以增加食品安全和负担能力?专注于尼日利亚,本文使用了对200个政府和农业食品系统利益相关者进行的调查的最佳-最差缩放技术,以检查他们对蔬菜和鱼类价值链的安全性和可负担性的政策信念。我们发现,对于食品安全而言,利益相关者之间的分歧大于可负担性。抗生素过度使用和毒素暴露,缺乏知识,不同的利益相关者将薄弱的立法确定为食品安全的约束性约束,投入和基础设施的高成本,以及安全威胁,被视为大多数人负担能力的共同挑战,虽然不是全部,这两个价值链的利益相关者。总的来说,本文强调了信念在农业食品系统政策制定过程中的重要性,并强调不仅需要更深入地探索政策参与者之间存在分歧信念的来源。
Access to safe, affordable diets is paramount for improved nutritional outcomes. Yet, how do stakeholders perceive the binding constraints and requisite policy actions to increase food safety and affordability? Focusing on Nigeria, this paper uses best-worst scaling techniques applied to a survey of 200 government and agrifood system stakeholders to examine their policy beliefs on safety and affordability vis-à-vis the vegetable and fish value chains. We find that divergence among stakeholders is greater for food safety than affordability. While antibiotics overuse and toxin exposure, lack of knowledge, and weak legislation were identified by different stakeholders as the binding constraints for food safety, high costs of inputs and infrastructure, as well as security threats, were seen as common challenges for affordability across most, though not all, stakeholders for both value chains. Overall, the paper highlights the importance of beliefs in the agrifood system policymaking process and emphasizes the need to explore not only the existence but also the source of divergent beliefs among policy actors in greater depth.
