Cities are challenged by climate change, natural and technological disasters and related injustices. At least three fields address these challenges within cities: sustainability, emergency management and resilience. However, these three fields often still work in silos, separated by administrative structures. One way to promote a synergistic and integrative city-level approach across the three fields is through actively fostering collaboration. This can be facilitated through a competency-based capacity building program. So far, only few capacity building programs attempted to foster collaboration across departments and fields. To address this gap the researchers collaborated with the City of Tempe, Arizona, USA to implement a program that addresses the respective sets of competencies and concepts in these fields. The question was asked how these competency sets and concepts can be integrated into one capacity building program to support collaboration across departments. The focus was on emergency management and sustainability competencies respectively, as a literature review revealed paucity of a resilience competency framework. Three capacity building trainings were implemented and competency development was evaluated using a pre-post survey and analysis of training interactions. The results show that: i) overall collaboration across departments was facilitated; ii) participants demonstrated sustainability and emergency management competencies in at least one of the three trainings, iii) participants were satisfied with the trainings individually and combined into one training program. The work concludes with recommendations to increase the development of collaborative competencies and to foster collaboration in practice in the long-term as part of “institutional work” in order to influence administrative structures as well.

城市受到气候变化、自然和技术灾害以及相关不公正的挑战。至少三个领域应对城市内的这些挑战：可持续性、应急管理和弹性。然而，这三个领域通常仍然各自为政，被行政结构分隔开来。在三个领域促进协同和整合的市级方法的一种方法是积极促进合作。这可以通过基于能力的能力建设计划来促进。迄今为止，只有少数能力建设项目试图促进跨部门和跨领域的合作。为了解决这一差距，研究人员与美国亚利桑那州坦佩市合作实施了一项计划，该计划解决了这些领域的相应能力和概念集。问题是如何将这些能力集和概念整合到一个能力建设计划中，以支持跨部门的协作。重点分别是应急管理和可持续性能力，因为文献综述显示缺乏弹性能力框架。实施了三项能力建设培训，并使用对培训互动的事前调查和分析来评估能力发展。结果表明：i) 促进了跨部门的整体协作；ii) 参与者在三项培训中的至少一项中展示了可持续性和应急管理能力， iii) 参与者对单独的培训感到满意并将其合并到一个培训计划中。
