Project of Key Technologies of WEF Synergy Security Guarantee Passes Performance Evaluation
Post Time:2021-08-27Front:[ Large Medium Small ]

On April 26-27, 2021, the National Key Project Management Office of Nanjing Hydraulic Research Institute (NHRI) organized a performance evaluation meeting in Nanjing, China for the 6 subjects of the project of Key Technologies of Water-Energy-Food (WEF) Synergy Security Guarantee under the National Key R&D Program.The meeting invited 7 technical experts from Sun Yat-sen University, New Energy Chamber of Commerce of All-China Federation of Industry and Commerce, Hydrology Bureau of Yellow River Conservancy Commission, Tongji University, Zhengzhou University, Dalian University of Technology, and Institute of Geography Sciences and Natural Resources Research, CAS, and 2 financial experts from Beijing Institute of Certified Public Accountants and Chinese Academy of Agricultural Sciences, forming an expert panel. NHRI Vice President WU Shiqiang attended the meeting and delivered a speech. The meeting saw the attendance of more than 60 people, including project leader, subject leaders and technical backbones.

Subject 1: WEF interaction coupling mechanism and simulation technologies. Aiming at the overall goal of improving the intensive management of water, energy and food resources, the key scientific issues in WEF coupling mechanism have been sorted out, a WEF nexus simulation model established by disassembling the whole process of water, energy and food resources flows, and a coupling simulation software tool developed. Main innovations are the coupled simulation technology and calculation model of the whole process of WEF resources flows have been proposed, a coupled quantitative calculation of WEF flows in socio-economic process realized, and a new path provided for understanding the implicit relationship among the three types of resources flows. The technologies have been successfully applied in the study of WEF nexus and resources allocation simulation for Ordos City and Jiangsu Province with good application prospects.

Subject 2: National WEF synergy security development trend and spatial layout. The spatio-temporal evolution pattern of WEF supply-demand and synergy response relationship in China have been analyzed, the adaptation diagram and synergy security distribution map of WEF in China drawn, a synergy demand prediction model and a synergy security spatial layout optimization model established, and strategic suggestions for the optimal layout of resources allocation put forward based on the analysis of the development trend of WEF in 2030. Main innovations are a theoretical method of WEF synergy security evaluation has been constructed based on synergistic symbiosis theory, an evaluation index system of WEF synergy security established, and the synergy security evaluation and spatial layout optimization technology of WEF in China developed. Relevant results have provided important support for the Ministry of Natural Resources, China to study and formulate policies on land spatial use control, and for National Energy Administration to formulate policy documents of energy development in the Yangtze River Economic Belt and the Yellow River Basin. It is of great significance in optimizing WEF spatial layout, promoting the integrated management and sustainable utilization of resources, and improving the ability to guarantee people’s livelihood.

Subject 3: WEF nexus and guarantee technologies in major grain-producing areas of Northeast China. A quantitative analysis tool for the coupling simulation and multi-dimensional regulation of WEF has been constructed, a multi-level study completed for the entire region of major grain-producing areas in Northeast China and typical areas including Heilongjiang Province and Daqing City, the dynamic simulations of the internal relationships of WEF system and its external linkages with economic, social and environmental systems realized, current and future reciprocal feedbacks and synergy security evolution characteristics of WEF in study areas revealed, and the optimization pattern of regional WEF synergy security under different scenarios such as ecological priority, food production priority or economic benefit priority proposed. Main innovations are a quantitative “mechanism-simulation-evaluation” tool for WEF and economy-society-environment coupling study has been constructed, traditional computable general equilibrium model improved, and WEF nexus analyzed. The study results have provided a model tool support and regulation scheme reference for decision making related to regional WEF synergy security guarantee under new situation, with good application prospects.

Subject 4: WEF synergy security and guarantee technologies of energy bases in Northwest China. The statistical characteristics of water, energy and food resources in energy bases of Northwest China and their quantitative response linkage have been analyzed, the interaction mechanism and development law of WEF in typical energy bases revealed, the interaction pattern of WEF in typical energy bases adapted to the national energy development strategy proposed, and the synergy security technologies and schemes of WEF for energy bases in Northwest China proposed. Main innovations are the technology integrating inter-regional deployment, water rights transfer, and water saving-utilization combination for water resources development and utilization has been developed, the WEF synergy security guarantee technologies for energy development formulated, and the WEF synergy security guarantee schemes for energy bases in Northwest China proposed. The study results will help to improve the WEF synergy security guarantee level of energy bases in Northwest China and serve the ecological protection and high-quality development strategy of the Yellow River Basin, with bright application prospects.

Subject 5: WEF coordinated allocation and guarantee technologies of hydropower bases in Southwest China. The theory, technology and application of WEF synergy security guarantee based on resources flows have been studied for hydropower bases in Southwest China. Main innovations are the basic characteristics of regional water resources development and utilization, energy production and consumption, and food production and consumption and their correlation with hydropower development have been revealed, the statistical characteristics and supply-demand relationship of regional water resources, energy and food analyzed, and the WEF synergy security guarantee technologies proposed targeting at cascade scheduling, water deployment and allocation in main and tributary rivers, and irrigation and drainage alternation of water resources for the sustainable utilization of hydropower. The technologies have been successfully applied in the Yalong River Basin and served the national strategy for the development of the Yangtze River Economic Belt, with good application prospects

Subject 6: Study on WEF synergy security guarantee strategy. A WEF synergy security guarantee strategy has been constructed, and a risk management and control technology system for WEF cooperative governance systematically designed. Main innovations are a strategic framework of WEF synergy security guarantee with the concept of “water-dependent, ecological priority, food security-based and energy-based” has been proposed, a differentiated risk control technology of WEF synergy security developed, an operable risk control scheme of risk reduction-damage reduction-stability maintenance proposed, the inter-ministerial horizontal joint meeting system established for multi-departmental collaboration, and the legislation, system and mechanism of WEF synergy security guarantee innovated. The study results have been successfully applied in major grain-producing areas in Northeast China, energy bases in Northwest China, and hydropower energy bases in Southwest china, which have provided a solid theoretical basis and decision support tools to improve resource utilization efficiency in key regions of China, promote technology innovation and management innovation, guarantee the national water security, energy security and food security, and comprehensively promote the high-quality development of the country, with good application prospects.

The expert panel believed that the planned tasks and predetermined assessment indicators had been comprehensively completed in view of the above six subjects, achieving the expected goals and completing the assessment objectives set for the project in a high quality. Thus, it was unanimously agreed to pass the performance evaluation.
