Collaborative governance has been widely adopted since the early 2000s to manage complex natural resource issues, such as water quality and land degradation. Most research has focused on the main features and potential benefits of collaborative governance. However, few studies have studied how collaboration facilitates (or limits) implementation of natural resource planning policies, such as water planning. Studying how collaborative governance works during implementation sheds light on how the environmental outcomes are achieved. This research uses the Great Barrier Reef as large case study of water quality, which was implemented through six regional collaborative governance efforts. The Reef is one of the most important marine ecosystems of Australia. Water quality remains one of the main threats to the Reef's environmental health and resilience. Since the beginning of the 21st century, collaborative governance approaches have been adopted in the Reef's water quality planning to improve water quality conditions. Drawing on document analysis and semistructured interviews with key stakeholders, the study shows how nested collaborative governance arrangements operated in the achievement of environmental outcomes. Although the nested regional level of collaboration proved to be a useful spatial scale at facilitating reductions of land‐based runoff, the environmental outcomes achieved were moderate due to collaborative issues with state and federal levels, the powerful actors of the collaborative arrangements. This suggests the importance of improving collaborative processes within the nested governance approach (i.e., deliberation between the main actors on the policy instruments or collaborative “tools” for plan implementation).

研究协作治理如何促进自然资源计划政策的实施：大堡礁的水计划政策案例

自2000年代初以来，协作治理已广泛用于管理复杂的自然资源问题，例如水质和土地退化。大多数研究都集中在协作治理的主要特征和潜在收益上。但是，很少有研究研究协作如何促进（或限制）自然资源计划政策（例如水计划）的实施。研究协作式治理在实施过程中的工作方式，有助于了解如何实现环境成果。本研究使用大堡礁作为水质的大型案例研究，该研究是通过六个区域合作治理工作实施的。珊瑚礁是澳大利亚最重要的海洋生态系统之一。水质仍然是珊瑚礁的主要威胁之一 的环境健康和复原力。自21世纪初以来，在珊瑚礁的水质规划中采用了协作治理方法来改善水质状况。通过对主要利益相关者的文档分析和半结构化访谈，该研究显示了嵌套式协作治理安排如何在实现环境成果方面发挥作用。尽管嵌套的区域合作水平被证明是有助于减少陆上径流的有用空间尺度，但是由于与州和联邦级别（合作安排的强大参与者）之间的合作问题，实现的环境成果是中等的。这表明在嵌套治理方法中改善协作流程的重要性（即，
