粮食是人类生存的基础,保障粮食安全是“2030年可持续发展议程”的重要目标之一。论文基于粮食系统视角,从全球气候变化对粮食系统的作用、保障粮食安全对全球气候变化的影响,以及应对全球气候变化的粮食安全适应性策略出发,揭示粮食安全与全球气候变化的相互作用,系统梳理全球气候变化下的中国粮食安全问题。研究结果表明:1)全球气候变化导致粮食系统不确定性增加,且对中国粮食生产的影响加剧;2)粮食需求是全球气候变化的主要驱动力,粮食生产要素的重新配置加剧了全球气候变化;3)多尺度有机结合应对全球气候变化保障粮食安全需在微观上“藏粮于技”实现提质增效,在中观上“藏粮于地”注重生态建设,在宏观上坚持市场为主导完善粮食政策体系。全球气候变化背景下,保障粮食安全研究呈现从单一学科、单一维度、单一手段向依靠多学科开展多尺度、多要素、系统综合集成研究保障粮食安全转变,从高碳粮食系统向低碳高效粮食系统转变的趋势。 |

Food is one of the basic human needs. Achieving food security is one of the important goals of“The 2030 Agenda for Sustainable Development”. However, there is lack of system review of mutual influence between safeguarding food security and global climate change. Accordingly, this paper reports a critical review of the existing researches related to interactions between ensuring food security and global climate change. Effects of global climate change on the food system, impacts of ensuring food security on global climate change and adapting food security strategies against global climate change were systematically reviewed. The results indicated that, firstly, global climate change had increased uncertainty in the food system which had great impact on China's food production. Secondly, demand for food was one of the main drivers of global climate change, and the reconfiguration of crop production elements exacerbated global climate change. Thirdly, a synthetic approach is required for food security adaption strategies against global climate change, specifically, in the micro- level promoting technological progress and scientific management, in the meso- level strengthening resources and environment protection, and in the macro- level adhering to the laws of market and improving food policy system. Moreover, under the background of global climate change, research on ensuring food security presents two major trends: one is the change from single discipline, one dimension and single means into multi- disciplinary, multi- scale, multi- factor, comprehensive and integrated approach; the other is to turn a high- carbon food system into a low-carbon and high-efficient food system. |
