Ageing and urbanisation pose significant challenges for public health and urban planning. Ageing populations are at particular risk from hazards arising from urbanisation processes, some of which are in turn exacerbated by climate change. One approach for mitigating the negative effects of urbanisation on ageing populations is the leveraging of the beneficial effects of urban green infrastructure as a public health intervention in the planning process. We assessed the potential of available theoretical frameworks to provide the context for such leverage. This involved active engagement with academics and practitioners specialising in ageing, green infrastructure and health and well-being through a knowledge-brokering approach. We concluded that an integrated and comprehensive framework on the socio-cultural-ecological determinants of health is lacking. To address this, we present a set of principles for overcoming challenges to knowledge integration when working at the intersection of green infrastructure, ageing, health and well-being. Our findings—and the co-production process used to generate them—have wider significance for trans-disciplinary research into the benefits of the natural environment to human health and well-being as well as other complex and interconnected topics associated with global grand challenges.

老龄化和城市化对公共卫生和城市规划提出了重大挑战。人口老龄化特别容易受到城市化进程带来的危害的威胁，其中一些危害又因气候变化而加剧。减轻城市化对人口老龄化的负面影响的一种方法是利用城市绿色基础设施的有益影响作为规划过程中的公共卫生干预措施。我们评估了可用理论框架为此类杠杆作用提供背景的潜力。这涉及通过知识中介方法与专门研究老龄化、绿色基础设施以及健康和福祉的学者和从业者积极接触。我们的结论是，缺乏关于健康的社会文化生态决定因素的综合全面框架。为了解决这个问题，我们提出了一套原则，用于在绿色基础设施、老龄化、健康和福祉的交叉点工作时克服知识整合的挑战。我们的发现——以及用于生成它们的联合生产过程——对于跨学科研究自然环境对人类健康和福祉的益处以及与全球重大挑战相关的其他复杂且相互关联的主题具有更广泛的意义。
