Farmland abandonment is common in the southern EU countries. This complex phenomenon has a set of interlinked causes and consequences, among the latter the undermining of farmers’ cooperatives role as supply aggregators. The paper discusses a multi-actor farmland consolidation model that avoids some of the drawbacks identified by literature to some models of land mobilization, mostly transaction and agency costs. This model consists on a local-based strategy of common land management, led by a cooperative and supported by a set of external agents. As empirical evidences, we show the attitudes of cooperatives’ managers surveyed towards common land management and present a case study implementing this multi-actor model. This piece of evidence shows that strengthening social capital is crucial to the success of these social innovation experiences.

遗弃农田在欧盟南部国家很常见。这种复杂的现象有一系列相互关联的原因和后果，其中包括破坏农民合作社作为供应聚合者的作用。本文讨论了一种多参与者农田整理模型，该模型避免了文献中指出的某些土地动员模型存在的一些缺陷，主要是交易和代理成本。该模型包括以当地为基础的公共土地管理战略，由合作社领导并由一组外部代理提供支持。作为经验证据，我们展示了接受调查的合作社经理对共同土地管理的态度，并提供了一个实施这种多参与者模型的案例研究。这一证据表明，加强社会资本对于这些社会创新经验的成功至关重要。
