This research focuses on converting unused rooftops into extensive green roofs in Nador, Morocco, offering an innovative approach to enhancing outdoor thermal comfort in this region. Several advanced techniques were used, including photogrammetric restitution (for creating land use maps), integration of light detection and ranging data (for three-dimensional urban modeling), and meteorological data collection (for modeling urban climate conditions). The urban-multiscale-environmental-predictor solar and longwave environmental irradiance geometry (UMEP-SOLWEIG) model was crucial for precisely evaluating the thermal performance of green roofs and their influence on urban microclimates. This model considers considered various parameters, such as the sky view factor, wall height and aspect, and shading conditions, for accurate, comprehensive analysis. Additionally, for accurate, comprehensive analysis, a comparative evaluation was performed between the UMEP-SOLWEIG and ENVI-met models to assess the UMEP-SOLWEIG results. The findings were notable, demonstrating a substantial reduction (averaging over 3 °C) in the mean radiant temperature on 60% of rooftops, covering 55% of the total surface area. This highlighted the effectiveness of green roofs in improving outdoor thermal comfort. Furthermore, green roofs were closely associated with reductions in air-conditioning energy consumption, with considerable reductions ranging from 17.53% to 43.82%. These savings translated to estimated financial benefits ranging from USD 1.63–4.07 million. These figures clearly verified the notable economic impact of green roofs despite their initially high costs (approximately USD 84.44 million). These potential long-term savings indicated that these investments are financially viable in the long run. The collected data were used to create thermal maps of the area using geographic-information-system tools. A thermal cadaster specific to green roofs was also developed, accessible online through Web mapping. Overall, this approach facilitates decision-making in urban planning by providing visual information on thermal variations, thereby aiding in the precise planning of measures against urban heat and promoting the use of green roofs to reduce environmental impact.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"22 4","pages":"Pages 410-422"},"PeriodicalIF":3.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143156848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that publications on carbon footprint have been increasing since 2013, and more so after 2017. Regarding domain influence, China and its academic institutions show a strong influence. In addition, a cluster analysis of the keywords of all publications shows seven categories, encompassing carbon footprint accounting methods and research priorities. Furthermore, a qualitative analysis of the research methods and subjects related to carbon footprint reveals the need to increase communication and collaboration among different disciplines and countries/regions to strengthen the construction of carbon footprint systems.

The key findings include the following: ① Chinese research trends: scholars predominantly concentrate on the “three rural” issues (related to agriculture, rural areas, and small-scale farmers) and social support mechanisms for vulnerable rural populations. With policy shifts, rural revitalization, tourism, governance, social trust, and multi-dimensional poverty are poised to emerge as hot topics for the future. For further refinement, we suggest that the application of SNA in rural community research could benefit from content expansion, long-term studies, and innovative modelling techniques. ② Research by international scholars has been primarily directed toward the physical and mental health of rural residents, as well as socioeconomic issues. Despite these studies covering a range of typical cases across various nations, a conspicuous lack of thorough, systematic, and prolonged efforts focused on rural community development in specific regions remains. Additionally, health issues affecting rural residents are expected to sustain long-standing and focused international academic attention.

Following the principles of relevance, scientific rigor, universality, reliability, and timeliness, this study constructs an assessment index system for sustainable development, covering seven themes corresponding to the UN Sustainable Development Goal 11. Through detailed calculations, we obtained sustainable development indices for 139 Chinese cities from 2016 to 2022 and analyzed them in three dimensions: distribution dynamics, regional differences, and convergence. The key findings are as follows. First, the level of sustainable development showed improvement, with the average score of included cities increasing by 11.88% from 2016 to 2022. Second, the level of sustainable development was relatively balanced, maintaining low Gini coefficients between 0.05 and 0.06.

From a regional perspective, a σ convergence feature was observed in the northeastern but not in the western region. Fourth, both overall absolute <em>β</em>-convergence and conditional <em>β</em> effects were significant. Regional absolute <em>β</em>-convergence and conditional <em>β</em>-convergence were also significant.

As the global community intensifies its efforts to implement the sustainable development goals (SDGs), the demand for assessing progress in urban sustainable development has increased.

Cities participating in these evaluations often encounter difficulties in matching indicators or the absence of certain indicators. In this context, urban decision-makers and planners urgently need to identify substitute indicators that can express the semantic meaning of the original indicators and consider the availability of indicators for participating cities. Hence, this study explores the relationships of substitution between indicators and constructs a collection of substitute indicators to serve as a reference for sustainable urban development assessment. Specifically, building on a review of international and Chinese indicators related to urban sustainability assessment, this study employs natural semantic analysis methods based on the Word2Vec model and cosine similarity algorithm to calculate the similarity between indicators related to sustainable urban development.

Using a step-by-step “eliminate–replace–augment” indicator selection method that takes mature indicators from existing standards for city evaluation, we form an ILCSD that responds to the SDGs while meeting China’s specific needs. Using the ILCSD, cities can select a set of indicators to assess and monitor their strengths and weaknesses. Through empirical analysis, we verify the feasibility of using ILCSD to construct a CSD evaluation system for Beijing, China. For the first time, ILCSD has established a mapping relationship between the core indicators from domestic and foreign standards of city development and the SDGs . It provides a tool for cities in different regions, at different stages of development and with different endowment types to select high-quality indicators according to local conditions, effectively solving the “last mile” problem of SDGs implementation at the city level. In the process of implementing indicators, we further suggest that important indicators with incomplete statistical data should nevertheless be included in the scope of cities’ statistical monitoring.
