在管理城市洪水风险时，优先考虑基础设施和技术解决方案的传统洪水风险管理很重要，但不足以将风险降低到可接受的水平，特别是在非正规住区。了解如何治理洪水风险需要补充洪水风险干预措施，以便能够采取更具协作性的应对措施来管理洪水风险。以南非开普敦为例，那里每年的洪水事件都会影响许多非正规住区，我们确定了协作治理的障碍，可以解决这些障碍，以帮助建立更全面的洪水管理方法，主动降低洪水风险。我们的重点是地方政府作为洪水风险管理的关键领域。使用节点治理框架，我们评估了开普敦市四个不同地方政府部门的心态、技术、资源和制度结构以及他们在洪水风险管理方面的合作程度。确定了协同城市洪水风险管理的四个关键制约因素：技术官僚方法的主导、缺乏特定能力、如何分担风险的挑战以及政治争论和短期主义。揭示节点治理的本质是确定合作可能性、从而加强城市洪水管理过程的关键一步。这对于南半球国家的城市环境风险管理尤为重要，因为南半球国家需要参与包括非正规政治以及社会和环境变化复杂性在内的发展议程。
When managing urban flood risk, traditional flood risk management which prioritizes infrastructural and technical solutions is important but is not sufficient to reduce the risk to acceptable levels, particularly in informal settlements. Understanding how flood risk is governed needs to complement flood risk interventions in order to be able to move towards a more collaborative response to managing flood risk. Drawing on the case of Cape Town, South Africa, where annual flood events impact on many informal settlements, we identify barriers to collaborative governance that could be addressed to help to build a more holistic flood management approach that proactively reduces flood risk. Our focus is on local government as a key arena of flood risk management. Using a nodal governance framework, we assess the mentalities, technologies, resources and institutional structures of four different local government departments in the City of Cape Town and the extent to which they collaborate on flood risk management. Four key constraints to collaborative urban flood risk management are identified: the domination of a technocratic approach, lack of particular capacities, the challenge of how to share risk, and political contestation and short-termism. Unpacking the nature of nodal governance is a key step in identifying possibilities for collaboration and thus strengthening processes of urban flood management. This is particularly important for urban environmental risk management in the global South, which needs to engage with a development agenda that includes the politics of informality and the complexities of social, as well as environmental, change.
