City-scale climate information is needed to inform policy, decision-making and climate action in the context of development agendas like Sustainable Development Goals (SDGs), Sendai Framework of Disaster Risk Reduction, New Urban Agenda and the Paris Agreement. Traditional approaches in climate services are often top-down and inadequate in meeting the needs of stakeholders in urban areas like African cities. To enhance the provision of relevant climate information, it is important to understand the context of the urban environment in question and decision-making processes. Researchers from the FRACTAL project used participatory, transdisciplinary co-production approaches to understand the context of Harare and to investigate perceptions and values that underpin decision-making in the water sector. These were tied to historical trends in climate and hydrological flows as well as narratives of future climate and hydrological scenarios to draw timely, relevant information for policy, and practice implementation and for building resilience in the city. Lessons learnt, which are applicable to similar African cities, show the importance of understanding decision-making in providing a context to build on for distilling, improving and mainstreaming climate information services and that engagement processes are useful in building sustained working relationships and trust.

在诸如可持续发展目标（SDG），《仙台减少灾害风险框架》，《新城市议程》和《巴黎协定》等发展议程的背景下，需要城市规模的气候信息来为政策，决策和气候行动提供信息。气候服务的传统方法通常是自上而下的，不足以满足非洲城市等城市地区利益相关者的需求。为了增加有关气候信息的提供，重要的是要了解所讨论的城市环境和决策过程。FRACTAL项目的研究人员使用参与式，跨学科的联合生产方法来理解哈拉雷的背景，并调查支持水务部门决策的观念和价值观。这些都与气候和水文流量的历史趋势以及未来气候和水文情景的叙述联系在一起，以便及时地获取相关信息，以用于政策，实践实施以及增强城市的适应力。吸取的教训适用于类似的非洲城市，显示出了解决策的重要性，为提炼，改进和主流化气候信息服务奠定基础，参与过程对于建立持久的工作关系和信任很有用。（198个字）。表明了解决策的重要性，为提炼，改进和主流化气候信息服务提供基础，参与过程对于建立持续的工作关系和信任很有用。（198个字）。表明了解决策的重要性，为提炼，改进和主流化气候信息服务提供基础，参与过程对于建立持续的工作关系和信任很有用。（198个字）。
