项目摘要

Three quarters of crop species depend on pollinators, but the service they provide is under increasing threat from climate change. Declines inpollinators are predicted to have negative impacts on human health as key dietary micronutrients in insect pollinated crops such as vitamin A andfolate are lost from the diet. This "hidden hunger" is predicted to cause significant global health burdens. Climate change is already affectingpollinators, for example, the geographic range of bumblebees is shrinking as their southern range moves northwards, the synchrony betweenflowering plants and their pollinators is being disrupted and climate change is predicted to decrease bee species richness by 8-18% in some areas.Pollinator loss disproportionately harms developing countries, as they are both less resilient to yield drops and more reliant on the micronutrientsfound in small-scale pollinator-dependent crops. Providing population-wide vitamin supplementation is neither practical nor sustainable in remoteparts of the world; instead, diversifying the diet by increasing access to micronutrient-rich fruits, vegetables and legumes could provide a solution.Fortunately, pollinator declines can be reversed, at least locally. Moreover, if the effect of climate change on pollinators is understood, habitatmanagement can be used to mitigate against its effects. There is evidence of climate change, pollinator declines and micronutrient deficiency in ourfocal country Nepal and our research vision has four components: 1) to predict the effect of climate change on crop pollinators in Nepal; 2) topredict the ensuing impact on crop production and micronutrient intake; 3) run a field experiment to test the resilience of insect pollinated crops toclimate change; 4) develop a policy and education package to mitigate the effects of climate change on crop pollination and micronutrient intake.Working with health professionals in Nepal, our international team of natural scientists and health scientists will provide information and innovativesolutions for an understudied impact of climate change on human health.

四分之三的作物物种依赖于授粉者，但它们提供的服务正受到气候变化的日益威胁。据预测，授粉昆虫的减少将对人类健康产生负面影响，因为昆虫授粉作物中的关键膳食微量营养素，如维生素A和叶酸，将从饮食中流失。据预测，这种“隐性饥饿”将造成重大的全球健康负担。气候变化已经影响到传粉者，例如，大黄蜂的地理范围正在缩小，因为它们的南部范围向北移动，开花植物和传粉者之间的同步正在被破坏，预计气候变化将使某些地区的蜜蜂物种丰富度减少8-18%。因为它们对产量下降的适应能力较低，而且更依赖于小规模授粉作物中发现的微量营养素。在世界偏远地区，提供全民维生素补充剂既不切实际，也不可持续。相反，通过增加富含微量营养素的水果、蔬菜和豆类的获取来实现饮食多样化可以提供一个解决方案。幸运的是，传粉媒介的减少是可以逆转的，至少在当地是这样。此外，如果了解气候变化对传粉者的影响，就可以利用生境管理来减轻其影响。我们的重点国家尼泊尔有气候变化、传粉媒介减少和微量营养素缺乏的证据，我们的研究愿景有四个组成部分：1）预测气候变化对尼泊尔作物传粉媒介的影响; 2）预测随之而来的对作物产量和微量营养素摄入量的影响; 3）进行田间实验，测试昆虫传粉作物对气候变化的适应能力; 4）制定一套政策和教育方案，以减轻气候变化对作物授粉和微量营养素摄入的影响。我们的国际自然科学家和健康科学家团队将与尼泊尔的卫生专业人员合作，为气候变化对人类健康的影响提供信息和创新解决方案。
