Situated within the sociological debate on social change, the present article examines the potential for food movements to transform agrifood systems. Existing analyses within the field of food studies predominantly examine agrifood systems at either the global or local level. By contrast, our analysis begins with the national sphere, and seeks to demonstrate how national transformations relate to those on the global and local scales. We, thus, challenge the approach of dichotomous scales by providing categories and perspectives that highlight the relational and interdependent character of food movements. To do so, we examine the Marcha das Margaridas – a movement based in Brasil – and its achievements in transforming the national agrifood system. Established in 2000, the Marcha das Margaridas is a feminist mobilization that plays a central part in the fight against inequalities in agrifood systems and foments discussion of food politics on a multiplicity of scales. We demonstrate this by mapping the march’s public policy achievements, and by analyzing three of these in detail.

在关于社会变革的社会学辩论中，本文探讨了粮食运动改变农业食品体系的潜力。食品研究领域中的现有分析主要在全球或地方一级检查农业食品系统。相比之下，我们的分析从国家领域开始，力图证明国家转型与全球和地方尺度的转型之间的关系。因此，我们通过提供突出食物运动的相关性和相互依存性的类别和观点来挑战二分法的方法。为此，我们考察了总部设在巴西的玛格达达·玛格丽达斯运动（Marcha das Margaridas）及其在改变国家农业食品体系中所取得的成就。Marcha das Margaridas成立于2000年这是一次女权主义动员，在反对农业食品系统中的不平等斗争以及在多种尺度上引发对食品政治的讨论中发挥着核心作用。我们通过绘制三月的公共政策成就并详细分析其中三项来证明这一点。
