Abstract In many parts of the world, people are coming together to experiment with ways to collectively take care of their livelihoods and create practical solutions to their needs. Guided by principles of solidarity, these grassroots initiatives represent rich contexts for research on the urban commons: what qualifies them as commons, and how do they emerge, develop, sustain and dissolve – or transform over time? This research dissects the commons character of a food network which emerged from Porto's solidarity economy movement in a post-crisis context. Following an action-research approach and methodological triangulation, we develop a qualitative analysis of a “prosumers” group, where both production and distribution were performed weekly by consumers themselves. We first analyze how the initiative emerged and then look at how its principles and democratic qualities relate to commons theories and frameworks. We then delve into the main dilemmas of its commoning practices and reflect about its transformative character and liminal role as a temporary urban commons. Despite ceasing its activities, there was a lived-experience and a knowledge commons which allowed it to be appropriated in new terms, and thus food networks as urban commons persist.

作为城市公共资源的食品网络：葡萄牙“产消者”群体的案例研究

摘要 在世界许多地方，人们聚集在一起尝试共同照顾他们的生计并为他们的需求创造实用的解决方案的方法。在团结原则的指导下，这些草根倡议代表了研究城市公地的丰富背景：什么使它们成为公地，以及它们如何出现、发展、维持和消解——或随着时间的推移而转变？这项研究剖析了在后危机背景下从波尔图的团结经济运动中出现的食物网络的公共特征。遵循行动研究方法和方法论三角测量，我们对“产消者”群体进行了定性分析，其中消费者自己每周进行生产和分销。我们首先分析该倡议是如何出现的，然后研究其原则和民主品质如何与公地理论和框架相关联。然后，我们深入探讨其共同实践的主要困境，并反思其作为临时城市公地的变革性特征和阈限作用。尽管停止了活动，但仍有生活经验和知识公地，使其能够以新的方式被占用，因此作为城市公地的食物网络仍然存在。
