Climate change has increased pluvial flood risks in cities around the world. To mitigate floods, pluvial risk maps with climate change scenarios have been developed to help major urban areas adapt to a changing climate. In some cases, subnational governments have played a key role to develop these maps. However, governance research about the role of subnational governments in geospatial data development in urban water transitions has received little attention. To address this gap, this research applies the Governance Assessment Tool as an evaluative framework to increase our understanding of the governance factors that support the development of pluvial flood risk maps at the subnational level. For this research, we selected the region of Flanders in Belgium. This region is considered among the frontrunners when it comes to the creation of a pluvial flood risk map with climate change scenarios. Data have been collected through in-depth interviews with steering committee actors involved in the development process of the map. The research identified that the current governance context is supportive of the creation of the flood risk map. The government of Flanders plays a key role in this process. The most supportive qualities of the governance context are those related to the degree of fragmentation (extent and coherence), while the less supportive ones are those related to the “quest for control” (flexibility and intensity). Under this governance context, government actors play the primary role. The Flemish government led the maps’ creation process and it was supported by the lower governmental levels. As the provincial government was an important actor to increase local participation, collaboration with private and non-governmental actors in the steering committee was more limited. The financial resources were also limited and the process required a continuous development of trust. Yet, the Flemish Environmental Agency, with the use of technology, was able to increase such trust during the process.

评估治理环境支持以创建带有气候变化场景的雨洪风险图：佛兰德地方政府案例

气候变化增加了世界各地城市的洪水泛滥风险。为了缓解洪水，已开发了具有气候变化情景的小雨风险图，以帮助主要城市地区适应气候变化。在某些情况下，地方政府在开发这些地图方面发挥了关键作用。但是，有关地方政府在城市水过渡中地理空间数据开发中的作用的治理研究很少受到关注。为了解决这一差距，本研究将“治理评估工具”作为评估框架，以加深我们对支持在国家以下一级支持开发洪水洪水风险图的治理因素的理解。为了进行这项研究，我们选择了比利时的法兰德斯地区。在创建包含气候变化情景的小洪水风险地图时，该地区被认为是领先者。通过与参与地图开发过程的指导委员会参与者的深入访谈收集了数据。研究表明，当前的治理环境支持洪水风险图的创建。法兰德斯政府在此过程中扮演着关键角色。治理环境中最支持的质量是与分散程度（范围和一致性）相关的质量，而次要支持的质量则与“寻求控制”（灵活性和强度）相关的质量。在这种治理背景下，政府行为者起着主要作用。法兰德斯政府领导了地图的创建过程，并得到了下级政府的支持。由于省政府是增加地方参与的重要角色，因此与私人和非政府角色在指导委员会中的合作更加有限。财务资源也很有限，该过程需要不断发展信任。然而，佛兰芒环境局通过使用技术在此过程中增加了这种信任。
