Due to the high concentration of people and infrastructures in European cities, the possible impacts of climate change are particularly high (cities’ social, economic and technical vulnerabilities). Adaptation measures to reduce the sensitivity of a city to climate risks are therefore of particular importance. Nevertheless, it is also common to develop compact and dense urban areas to reduce urban sprawl. Urban infill development and sustainable spatial climate policies are thus in apparent conflict with each other. This article examines how German cities deal with the tensions between these two policy fields. Using six case studies, a new heuristic analysis method is applied. This study identifies three key governance aspects that are essential for promoting the joint implementation: instruments, organisation and interaction. Based on our case studies, we conclude that successful implementation can only be achieved through integrative governance including all three domains.

由于欧洲城市人口和基础设施高度集中，气候变化的可能影响特别大（城市的社会、经济和技术脆弱性）。因此，降低城市对气候风险敏感性的适应措施尤为重要。尽管如此，开发紧凑和密集的城市地区以减少城市扩张也很常见。因此，城市填充开发和可持续的空间气候政策显然相互冲突。本文考察了德国城市如何处理这两个政策领域之间的紧张关系。使用六个案例研究，应用了一种新的启发式分析方法。本研究确定了对促进联合实施至关重要的三个关键治理方面：工具、组织和互动。
