研究人员强调了气候变化作为农业环境影响的额外放大器，通过降低农业生产力、减少农药的效果、增加土壤侵蚀、加速作物疾病和害虫的增长及扩展范围以及增加土地开垦来加剧农业的环境影响。
研究人员识别出气候变化通过多种途径加剧农业温室气体排放，形成一个可能强大的气候变化强化反馈循环。气候变化带来的挑战突显了过渡到可持续、气候适应性农业系统的紧迫性。这需要去投资那些既加速采用提供多重效益的已验证解决方案又能够发现和推广新的有益过程和食品产品。
研究人员表示，农业的全球环境影响预计将继续扩大，这受到人口和经济增长以及饮食变化的驱动。

Abstract: Agriculture’s global environmental impacts are widely expected to continue expanding, driven by population and economic growth and dietary changes. This Review highlights climate change as an additional amplifier of agriculture’s environmental impacts, by reducing agricultural productivity, reducing the efficacy of agrochemicals, increasing soil erosion, accelerating the growth and expanding the range of crop diseases and pests, and increasing land clearing. We identify multiple pathways through which climate change intensifies agricultural greenhouse gas emissions, creating a potentially powerful climate change–reinforcing feedback loop. The challenges raised by climate change underscore the urgent need to transition to sustainable, climate-resilient agricultural systems. This requires investments that both accelerate adoption of proven solutions that provide multiple benefits, and that discover and scale new beneficial processes and food products.
