However, with the SDG process now halfway through, the evaluation of SDG 14 has yet to be initiated. The study presents an evaluation system based on Pressure-State-Response and SDG 14, which evaluated the trend and spatial characteristics of CMSD in China from 2012 to 2021. In addition, the investigation estimated the scores of SDG 14 targets for 11 coastal provinces and analyses the synergies and trade-offs among SDG 14 targets. Finally, the trajectories of the CMSD and SDG 14 targets were simulated for different future scenarios. The main findings are as follows: 1) CMSD increased by 3.24 % from 2012 to 2021, accompanied by a decline in Response subsystem and an increase in both Pressure and State subsystems. 2) CMSD exhibited improvement in Zhejiang, Guangdong, and Hainan Provinces, while the most significant decline was observed in Liaoning Province. All coastal provinces in China were dominated by the subsystem of Pressure subsystem. 3) In terms of the scores of SDG 14's targets, the largest gap was found in the scores of SDG 14.5 which indicates that there are significant differences in the development of MPAs in different coastal provinces; and the smallest gap was found in SDG 14.1, which demonstrates their general concern for marine pollution management and reduction of pollution discharges in coastal areas. 4) The synergy-tradeoff analysis of the SDG 14 targets reveals four pairs that have consistently maintained synergy at the 5 % significance level, while only one pair has maintained trade-offs at the 5 % significance level. 5) The results of the scenario simulation suggest that SDG 14.2 and SDG 14.4 should follow the Management Strengthening Pathway, while other targets performed better under the Green Development Pathway. This study conducts a marine sustainable development assessment using China as a case study. It not only clarifies the development status of SDG 14 targets at both the national and regional levels in China but also offers valuable insights for international efforts to evaluate SDG 14.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"111 ","pages":"Article 107753"},"PeriodicalIF":9.8,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142747238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that China's grain production consumed 2308 billion cubic metres of GRSW in 2014. On the demand side, 97 % of this water usage was attributed to domestic consumers, with significant contributions from Shandong, Hebei, Henan, and Jiangsu provinces. Additionally, the demand of products from China's food manufacturing, accommodation, and catering sector by Japan, the United States, and South Korea markedly influences GRSW utilisation in China. From the supply perspective, the grain sectors in Shandong, Hebei, and Henan serves as the primary domestic suppliers.

Topsoil contains the highest amount of organic carbon in soil layers, and conserving topsoil can provide an important solution to climate change. In South Korea, an extensive amount of topsoil has been lost due to the development of industrial complexes through land conversion. This study aims to quantify the potential organic carbon losses resulting from reductions in forest and agricultural land caused by the development of industrial complexes over three years. Over the past decade, 6.2 % of the national agricultural land (equal to 1302.73 km<sup>2</sup>) and 1.2 % (equal to 801.68 km<sup>2</sup>) of forest land were lost. These losses in agricultural and forest land correspond to an estimated loss of soil organic carbon equal to 7,139,356 Mg from the agricultural land and 7,794,831 Mg from forest land. After mineralization, this can result in 551,606 and 1,637,011 Mg of CO<sub>2</sub> being released in the atmosphere from agricultural and forest land respectively. The most significant finding of this study is that the average annual potential organic carbon losses from the reductions of agricultural and forest land due to the development of industrial complexes over a recent three-year period are respectively equivalent to 30 % and 90 % of the average annual nationwide loss over the past 10 years. This indicates the urgent need for effective topsoil management within the Environmental Impact Assessment (EIA) framework.

The focus is on 11 kW, 4-pole motors, representing typical industrial applications. Results show that IE5 SynRMs and PMSMs offer significantly higher operational efficiency, with PMSMs reaching 95 % efficiency compared to 92.7 % for SCIMs. However, the environmental trade-offs are notable: SynRMs require 156.9 kg of materials, including 80.5 kg of electrical steel, while PMSMs demand 1.8 kg of rare earth materials, contributing to higher manufacturing impacts.

This study enhances the Well-to-Wheel (WTW) model to capture the interactions between vehicle emissions and the evolving energy sector by incorporating changes in energy mixes and regional energy trade across Chinese provinces. The enhanced WTW model aims to improve the accuracy of data and models, emphasizing the need to reflect distinct regional energy configurations and emission characteristics precisely. According to a WTW analysis, between 2030 and 2040, vehicles delivered in 2040 are expected to show a reduction in emissions of 55.5% to 62.5% compared to those delivered in 2030 across various provinces in China. Each province experiences varying degrees of reduction, influenced by the transition to cleaner energy sources, cross-regional trading of alternative fuels, and variations in annual vehicle driving distances. By 2040, the WTW emissions from BEVs could decrease by up to 31 g CO<sub>2</sub>eq/km, and those from HFCVs by up to 11 g CO<sub>2</sub>eq/km. For vehicles delivered in the midpoint year of 2035 during the 2030–2040 period, pronounced disparities in WTW emissions among provinces are observed: Hebei, heavily reliant on coal, exhibits the highest WTW emissions for all vehicle types (69.0 g CO<sub>2</sub>eq/km for Sedan-BEVs, 76.7 g CO<sub>2</sub>eq/km for SUV-BEVs, 49.2 g CO<sub>2</sub>eq/km for Sedan-HFCVs, and 67.9 g CO<sub>2</sub>eq/km for SUV-HFCVs), while Yunnan, rich in renewable resources, records the lowest (8.0 g CO<sub>2</sub>eq/km for Sedan-BEVs, 8.8 g CO<sub>2</sub>eq/km for SUV-BEVs, 1.7 g CO<sub>2</sub>eq/km for Sedan-HFCVs, and 2.3 g CO<sub>2</sub>eq/km for SUV-HFCVs).
