There is a growing need to (1) better understand spaces in which human-animal interactions occur in ways that increase the risk of emerging infectious disease (EID), and (2) identify the opportunities for mitigating EID risk available to urban planning. Peri-urban areas—which are typically under-governed, undergoing significant environmental change and highly susceptible to zoonotic disease transfer--are especially important in this regard. In this research note, we briefly explore how climate change is contributing to both peri-urbanization and EID risk. First, climate change is linked to the displacement of people and other species into peri-urban areas, thereby increasing opportunities for zoonotic disease transfer. Second, whether coastal or inland, peri-urban space, characterized by low resources and inadequate services, is also typically vulnerable to mounting climate impacts including severe weather events, sea level rise, flooding, erosion, drought, salinization and heat waves that create socio-ecological conditions amenable to EID outbreaks. These relationships are particularly alarming given that peri-urban environments abut urban areas creating numerous pathways for the movement of EIDs into larger populations. In this research note, we briefly explore these relationships and illustrate them with a causal loop diagram of climate change-peri-urban displacement-EID interactions based on field work in Malawi. We conclude by emphasizing the need for improved EID risk management and suggest that bringing together the environmental expertise of the conservation community with that of planners through a more convivial urbanism that draws on the concept of working landscape conservation might be a beneficial approach.

研究报告:气候变化、城郊空间和新发传染病

越来越需要 (1) 更好地了解以增加新发传染病 (EID) 风险的方式发生人与动物相互作用的空间,以及 (2) 确定减轻城市规划可用的 EID 风险的机会。城郊地区——通常管理不善、环境发生重大变化且极易受到人畜共患病传播——在这方面尤为重要。在本研究报告中,我们简要探讨了气候变化如何导致周边城市化和 EID 风险。首先,气候变化与人类和其他物种迁移到城郊地区有关,从而增加了人畜共患病传播的机会。二、无论是沿海还是内陆,周边- 以资源不足和服务不足为特征的城市空间通常也容易受到气候影响的影响,包括恶劣的天气事件、海平面上升、洪水、侵蚀、干旱、盐碱化和热浪,这些影响造成社会生态条件易于爆发 EID。考虑到城市周边环境与城市地区相邻,为 EID 向更多人口转移创造了许多途径,这些关系尤其令人担忧。在此研究报告中,我们简要地探讨这些关系,并说明它们与气候的环路图变化-城郊-基于马拉维实地工作的城市流离失所-EID相互作用。最后,我们强调需要改进 EID 风险管理,并建议将保护社区的环境专业知识与规划者的环境专业知识结合起来,通过利用景观保护工作概念的更欢乐的城市化可能是一种有益的方法。
