摘要
在气候变化背景下,确保全球粮食安全成为人类面临的最艰巨挑战之一。本文围绕粮食安全的四大维度,较为系统地表述了气候变化对全球粮食安全的压力传导机制,并详细阐述了气候变化和非气候因素对全球粮食安全的复合效应,力图多维度展现气候变化对全球粮食安全的影响程度。研究结果表明,气候变化通过扰乱粮食的生产、储存、运输、销售、消费等环节,对粮食安全的所有维度均造成了负面影响。气候变化具有倍增效应,它加剧了非气候因素对全球粮食安全的负面影响。为避免气候变化和其他环境问题引发的灾难性后果,确保所有人的粮食和营养安全,大力推动气候韧性的全球粮食系统转型是当务之急。未来世界各国应致力于构建更高效、更包容、更有韧性和更可持续的全球粮食系统,并将推行基于自然的农业生产方式、推广可持续的农业土地和水资源管理模式、加大对小规模农业生产者的支持力度、实施综合性的农业发展和气候变化政策等作为战略重点。
In the context of climate change,ensuring global food security becomes one of the most daunting challenges facing humanity.This paper centers on the four dimensions of food security,elaborates the pressure transmission mechanism of climate change on global food security,and the compound effect of climate change and non-climate factors on global food security in an attempt to show the extent of climate change’s impact on global food security in a multi-dimensional way.The analysis shows that climate change negatively affects all dimensions of food security by disrupting food production,storage,transportation,distribution,and consumption.Climate change has a multiplier effect,which exacerbates the negative impact of non-climatic factors on global food security.To avoid catastrophic consequences caused by climate change and other environmental issues and to ensure food and nutrition security for all,it is imperative to vigorously promote the transformation of climate-resilient global food system.In the future,countries around the world should strive to build a more efficient,inclusive,resilient and sustainable global food system and focus on pursuing nature-based agricultural production methods,promoting sustainable models of agricultural land and water management,increasing support for small-scale agricultural producers,and implementing integrated agricultural development and climate change policies,as strategic priorities.
