Given the impact of agriculture on the environment, pro-environmental farming practices are growing in importance. Collaboration has an essential role to play in addressing environmental problems and promoting pro-environmental behaviors. As ecosystems are interdependent and diverse, their management is shared among numerous groups of people who are bound to collaborate to achieve common objectives. Through their farming practices and behaviors, farmers have a key role to play in protecting the environment, and by collaborating with each other or with other experts in ecology, objectives at a larger environmental scale could be achieved. However, a systematic review of the effect of collaboration on farmers' pro-environmental behaviors has not been conducted yet. We identified and reviewed 44 articles published in peer-reviewed scientific journals. We classified the articles into 4 categories reflecting reasons for collaboration: program participation, technical training, collaboration among farmers, and peer influence. Moreover, to consider the hierarchical structure in which collaboration unfolds, we differentiated between symmetrical and asymmetrical collaboration, allowing us to estimate whether one type of collaboration is more efficient than another. Overall, collaboration has a positive effect on farmers’ pro-environmental behaviors in all four categories, and both in symmetrical and asymmetrical collaborations. The review provides insights for future research directions. In particular, future collaborations with farmers may focus on groups of farmers instead of individuals, as well as on proactively involving them in the decision-making process.

鉴于农业对环境的影响，环保农业实践变得越来越重要。合作在解决环境问题和促进环保行为方面发挥着重要作用。由于生态系统是相互依存和多样化的，其管理由众多人群共同承担，这些人群必须合作以实现共同目标。通过农耕实践和行为，农民在保护环境方面可以发挥关键作用，通过相互合作或与其他生态学专家合作，可以实现更大环境规模的目标。然而，目前尚未对合作对农民环保行为的影响进行系统评价。我们确定并审查了同行评审科学期刊上发表的 44 篇文章。我们将文章分为 4 类，反映了合作的原因：项目参与、技术培训、农民之间的合作以及同行影响。此外，为了考虑协作展开的层次结构，我们区分了对称协作和不对称协作，从而使我们能够估计一种协作类型是否比另一种协作更有效。总体而言，合作对所有四个类别的农民的环保行为都有积极影响，无论是对称合作还是非对称合作。该评论为未来的研究方向提供了见解。特别是，未来与农民的合作可能会侧重于农民群体而不是个人，并积极让他们参与决策过程。
