The governance of several cross-cutting challenges, such as food security, climate change, and sustainable development, calls for integrative policy approaches. However, efforts to better theorize the drivers of integration beyond listing explanatory factors remain weak. Viewing integration as a process of policy change for dealing with complex problems, this study argues that policy integration analysis can benefit from an advocacy coalition approach (ACF) to address this theoretical gap. It illustrates the analytical framework by empirically investigating the drivers of policy (dis)integration in Brazil’s subnational water policy introduced in the 2010s. The level of conflict between coalitions, adjustment of policy beliefs, coordination within and across coalitions, and existence of venues for interaction and policy-oriented learning were presented as factors that can foster or hinder the integration of public policies. Moreover, the study discusses the potential to acknowledge in ACF the mechanisms for coordinating policy actors and instruments, which would facilitate the analysis of the policy processes of cooperation. It also demonstrates that recent droughts in Northeast Brazil have been increasingly related to the local impacts of climate change, contributing to reframing water management as a cross-sectoral climate and water governance issue. The analysis was based on a literature review, semi-structured interviews, and social network analysis.

对粮食安全，气候变化和可持续发展等若干跨领域挑战的治理要求采取综合政策方针。但是，除了列出解释性因素以外，为使整合驱动因素更好地进行理论化的努力仍然很薄弱。这项研究将整合视为解决复杂问题的政策变更过程，认为政策整合分析可以从倡导联盟方法（ACF）中受益，以解决这一理论空白。它通过对2010年代引入的巴西地方水政策中政策（解体）整合的驱动因素进行了实证研究，从而阐明了分析框架。联盟之间的冲突程度，政策信念的调整，联盟内部和整个联盟之间的协调，互动和以政策为导向的学习场所的存在被认为是可以促进或阻碍公共政策整合的因素。此外，该研究还讨论了在ACF中承认协调政策参与者和工具的机制的潜力，这将有助于分析合作的政策过程。它还表明，巴西东北部地区最近的干旱与气候变化对当地的影响越来越相关，这有助于将水资源管理重新定义为跨部门的气候和水治理问题。该分析基于文献综述，半结构化访谈和社交网络分析。该研究讨论了在ACF中承认协调政策参与者和工具的机制的潜力，这将有助于分析合作的政策过程。它还表明，巴西东北部地区最近的干旱与气候变化对当地的影响越来越相关，这有助于将水资源管理重新定义为跨部门的气候和水治理问题。该分析基于文献综述，半结构化访谈和社交网络分析。该研究讨论了在ACF中承认协调政策参与者和工具的机制的潜力，这将有助于分析合作的政策过程。它还表明，巴西东北部地区最近的干旱与气候变化对当地的影响越来越相关，这有助于将水资源管理重新定义为跨部门的气候和水治理问题。该分析基于文献综述，半结构化访谈和社交网络分析。有助于将水管理重新定义为跨部门的气候和水治理问题。该分析基于文献综述，半结构化访谈和社交网络分析。有助于将水管理重新定义为跨部门的气候和水治理问题。该分析基于文献综述，半结构化访谈和社交网络分析。
