全球化与粮食安全新格局

当今世界正面临“百年未有之大变局”,中国与全球的粮食安全面临重大挑战。为了系统认知全球化与粮食安全的新格局、新问题和新路径,邀请了十位来自不同专业领域的知名专家,就耕地增产潜力、农业水土资源与粮食生产、食物浪费、国际农产品贸易、重点农产品保供稳供、全球农业食物系统、双循环与企业行动、全球粮食生产与消费、国际粮安治理、粮食安全研究前沿等领域进行了一对一的交流访谈。访谈结果表明：全球农业食物系统进入复合型高风险时代,国际粮安治理面临资源、约束力、行动力等方面的挑战,凸显国家粮食安全尤其是进口依赖型农产品的保供稳供压力,需要加强国内农业供给侧改革与需求侧管理。全球化发生新变化,考验中国深化农业对外开放、参与全球粮安治理、实现国家粮食安全的能力水平。面对复杂的国际国内形势,国家粮食安全治理需要坚持系统思维、统筹国内国际、瞄准全产业链、强调风险管控、处理好政府与市场关系,进一步深入研究食物系统和粮食安全、生态系统和粮食安全、高质量发展与粮食安全、农业对外开放与粮食安全、双循环新格局与粮食安全等方面的具体方式路径,为新时期建立健全“以我为主、立足国内、确保产能、适度进口、科技支撑”的国家粮食安全战略提供科学参考。     

从安全防灾到韧性建设——国土空间治理背景下韧性规划的探索与展望

新形势下城市巨系统面临更多不确定性风险与未知扰动,要求安全防灾规划从目标对象、战略定位、技术手段与规划理念等方面做出适应调整,通过韧性城市建设引领区域安全稳定发展。对韧性城市的概念起源、理论发展与实践探索进行了梳理和评述,并结合我国“多规合一”后的国土空间规划体系改革,对空间治理背景下韧性规划的内涵特征、层级类型、流程形式与公共治理进行认识与思考;并从深化韧性城市的理论构建与机理研究、转变规划编制的设计思路和实践流程、完善韧性实践中的规划传导和尺度治理、关注韧性建设中的基层治理和公众参与四个方面,提出韧性规划的实践路径展望,力求有序推进我国城市公共安全现代化治理建设。     

Comprehensive and high-resolution emission inventory of atmospheric pollutants for the northernmost cities agglomeration of Harbin-Changchun, China: Implications for local atmospheric environment management

Using a bottom-up estimation method, a comprehensive, high-resolution emission inventory of gaseous and particulate atmospheric pollutants for multiple anthropogenic sectors with typical local sources has been developed for the Harbin-Changchun city agglomeration (HCA). The annual emissions for CO, NOx, SO₂, NH₃, VOC_S, PM_2.5, PM₁₀, BC and OC during 2017 in the HCA were estimated to be 5.82 Tg, 0.70 Tg, 0.34 Tg, 0.75 Tg, 0.81Tg, 0.67 Tg, 1.59 Tg, 0.12 Tg and 0.26 Tg, respectively. For PM₁₀ and SO₂, the emissions from industry processes were the dominant contributors representing 54.7% and 49.5%, respectively, of the total emissions, while 95.3% and 44.5% of the total NH₃ and NOx emissions, respectively, were from or associated with agricultural activities and transportation. Spatiotemporal distributions showed that most emissions (except NH₃) occurred in November to March and were concentrated in the central cities of Changchun and Harbin and the surrounding cities. Open burning of straw made an important contribution to PM_2.5 in the central regions of the northeastern plain during autumn and spring, while domestic coal combustion for heating purposes was significant with respect to SO₂ and PM_2.5 emissions during autumn and winter. Furthermore, based on Principal Component Analysis and Multivariable Linear Regression model, air temperature, relative humidity, electricity and energy consumption, and the urban and rural population were optimized to be representative indicators for rapidly assessing the magnitude of regional atmospheric pollutants in the HCA. Such indicators and equations were demonstrated to be useful for local atmospheric environment management.     

“十四五”时期生态环境重大制度政策创新的思考

用最严格的制度、最严密的法治保护生态环境,需要加快构建以治理体系和治理能力现代化为保障的生态文明制度体系。要增加制度供给,需从四个方面加快制度创新:一是发挥市场机制,健全多元体系;二是强化行政管理,落实地方责任;三是发挥社会机制,引导社会参与;四是强化法制建设,筑牢创新基础。

Developing sustainable products and services

In light of increasing pressures to adopt a more sustainable approach to product design and manufacture, the requirement to develop sustainable products is one of the key challenges facing industry in the 21st century. Hence, the concept of developing sustainable products as well as services is evolving as a key element of Cleaner Production. Sustainable product development initiatives (mainly through eco-design) have been evolving for some time to support companies develop more sustainable products. Ireland has been running the highly successful Environmentally Superior Products (ESP) initiative that supports industrial companies to incorporate a more sustainable approach to the development of products and/or services. The lessons learned from the ESP and other global Sustainable Product and Service Developments in industry and research, are being used to develop a method for effective sustainable product and/or service development (SPSD) in industry. The method is designed to provide pragmatic guidance to business and industry for developing sustainable products and services as well as incorporating this approach within existing corporate strategy, cleaner production and product development systems. This method is being developed by the authors at the Environmental Policy and Management Group (EPMG), Department of Environmental Science and Technology, Imperial College London, UK in conjunction with industry and practitioners. The method provides a framework for implementing SPSD throughout the entire lifecycle of a product and/or service. It can be used to identify, assess and implement the options for optimum sustainability in the design and development of a product and/or service. This paper describes the key features of this method.
