植物疾病的爆发对全球粮食安全和全世界的环境可持续性构成重大风险，并导致初级生产力和生物多样性的丧失，对受影响地区的环境和社会经济状况产生负面影响。气候变化通过改变病原体进化和宿主-病原体相互作用以及促进新的致病菌株的出现，进一步增加了爆发的风险。病原体的范围可以转移，增加植物疾病在新地区的传播。在这篇综述中，我们研究了在未来气候情景下植物病害压力可能如何变化，以及这些变化如何与自然和农业生态系统中的植物生产力相关。我们探讨了当前和未来气候变化对病原体地理学，疾病发病率和严重程度的影响，以及它们对自然生态系统，农业和粮食生产的影响。我们建议修改现有的概念框架，并将生态进化理论纳入研究，可以提高我们对未来气候中病原体传播的机械理解和预测，以减轻未来疾病爆发的风险。我们强调，需要建立一个与相关政府间组织密切合作的科学政策互动机制，以便在未来气候情景下有效监测和管理植物病害，确保粮食和养分的长期安全以及自然生态系统的可持续性。在这篇综述中，Singh等人探讨了未来气候情景对植物病原体负担和植物地理学的影响，它们与植物微生物组的相互作用以及对不同生态系统中植物疾病和生产力的影响。他们提出了确保长期全球粮食安全的不同方法。
Plant disease outbreaks pose significant risks to global food security and environmental sustainability worldwide, and result in the loss of primary productivity and biodiversity that negatively impact the environmental and socio-economic conditions of affected regions. Climate change further increases outbreak risks by altering pathogen evolution and host–pathogen interactions and facilitating the emergence of new pathogenic strains. Pathogen range can shift, increasing the spread of plant diseases in new areas. In this Review, we examine how plant disease pressures are likely to change under future climate scenarios and how these changes will relate to plant productivity in natural and agricultural ecosystems. We explore current and future impacts of climate change on pathogen biogeography, disease incidence and severity, and their effects on natural ecosystems, agriculture and food production. We propose that amendment of the current conceptual framework and incorporation of eco-evolutionary theories into research could improve our mechanistic understanding and prediction of pathogen spread in future climates, to mitigate the future risk of disease outbreaks. We highlight the need for a science–policy interface that works closely with relevant intergovernmental organizations to provide effective monitoring and management of plant disease under future climate scenarios, to ensure long-term food and nutrient security and sustainability of natural ecosystems. In this Review, Singh et al. explore the impact of future climate scenarios on plant pathogen burden and biogeography, their interaction with the plant microbiome and the consequences on plant disease and productivity in different ecosystems. They propose different approaches to ensure long-term global food security.
