This editorial introduces the Special Section “Commons and Social Movements”, which centers on how social movements and commons initiatives shape each other. The Section responds to the recent momentum gained by the “commons movement” in Europe and across the world, as well as the consolidation of a critical scholarship that expands the frontiers of institutional ecological economics for the study of the commons. The diversity of contributions included in the Section illustrates the novelty of the topic. Still, some transversal themes emerge, including the coevolution of movements and commons, the role of heterogeneities, and cross-scalar dynamics. Also promising are the authors' efforts to put the commons and social movement theories in dialogue via concepts like water rooted collectives, management opportunity structures, collective reactions to commons grabbing or liminal commons. Also important is the common understanding across all contributions about the potential of commons movements as sustainability transformation actors. Commons movements can break policy status quos but also prefigure, perform and scale up-and-out alternatives. This is probably the main take home message of this Section and we hope also a motivation to further a research agenda around it.

这篇社论介绍了“公地与社会运动”特节，重点关注社会运动和公地倡议如何相互塑造。该部分回应了欧洲和世界各地“公地运动”最近获得的势头，以及为研究公地扩展制度生态经济学前沿的批判性学术研究的巩固。本节中包含的贡献的多样性说明了该主题的新颖性。尽管如此，还是出现了一些横向主题，包括运动和公地的共同进化、异质性的作用和跨标量动力学。同样有希望的是作者努力通过水根集体、管理机会结构等概念将公地和社会运动理论进行对话，对公地抢夺或限制公地的集体反应。同样重要的是所有贡献的共识，即公地运动作为可持续性转型参与者的潜力。公地运动可以打破政策现状，但也可以预测、执行和扩大替代方案。这可能是本节的主要带回家的信息，我们希望也是围绕它推进研究议程的动力。
