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.
农业的全球环境影响预计将继续扩大,这主要是由人口增长、经济增长和饮食变化所驱动的。本综述强调气候变化是农业环境影响的另一个放大器,它会降低农业生产力、降低农用化学品的功效、增加土壤侵蚀、加速作物病虫害的生长和扩大范围,并增加土地开垦。我们确定了气候变化通过多种途径加剧农业温室气体排放,从而形成一个潜在的强大的气候变化增强反馈循环。气候变化带来的挑战凸显了向可持续、有气候韧性的农业系统转型的紧迫性。这需要投资,既要加速采用已经被证明有多种益处的解决方案,也要发现和推广新的有益过程和食品。
