The main objective was to assess the adequacy and efficiency of communal septic tank systems in informal settlements while helping local planners and authorities in their decision-making regarding Target 6.3. Quantitative and qualitative approaches were employed with secondary data from previous researchers, and primary data were collected from field surveys, observations, and interviews with members of the local community. The research was delimited to two village administrative divisions known as Rukun Warga (Village Administrative Division, RW): RW 7 and RW 8 of Lebak Siliwangi Kampung in Coblong District, Bandung, West Java, Indonesia. The findings were also compared with situations in other informal settlements in Brazil, Bangladesh, and Nairobi. The results indicated the inadequacy of communal septic tanks in informal settlements due to factors such as substandard system design, limited support and communication between authorities and residents, and the gap between septic tank availability and capacity vis-a-vis demand. Other limiting factors included limited land availability and irregular geomorphology, the latter of which affected the siting and operation of septic tanks due a lack of room for upgrades or expansion in response to continuous population growth. These findings illustrate the need to complement communal septic systems with flexible centralized or decentralized systems to achieve Target 6.3 of SDG 6.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"23 1","pages":"Pages 121-131"},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768336","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}

A knowledge graph was constructed for Chenzhou’s sustainable development, comprising 515 nodes, 3 209 relations, and 28 157 attributes. Sustainable measures and pathways were proposed based on this knowledge graph. The results showed that Chenzhou’s future sustainable development should focus on innovation, growth, emissions reduction, centering around high-quality and sustainable development. Promoting the transfer and transformation of scientific and technological achievements, accelerating the optimization and upgrading of industrial structures, and enhancing talent cultivation and recruitment will foster new quality productive forces, providing strong momentum and support for the high-quality and sustainable development of Chenzhou. To accelerate the green economy transition, Chenzhou should improve the market-oriented allocation system for resources and environmental factors, explore the “gross ecosystem product + eco-environment-oriented development” project implementation model, encourage enterprises to adopt environmental, social, and governance principles, and foster synergies between supply and demand. Furthermore, coordinating Chenzhou’s low-carbon city pilot projects and constructing carbon sequestration pathways that leverage nature-based solutions will help implement the “dual carbon” actions and enhance the city’s ability to respond to climate change.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"22 4","pages":"Pages 455-468"},"PeriodicalIF":3.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143156846","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}

Under China’s implementation of the “carbon peak and carbon neutrality” dual carbon strategic background, ESG has become an important tool to promote the achievement of the “dual carbon” goals and high-quality development. How enterprises can reasonably and effectively improve their ESG performance and promote their green and sustainable development has become a major practical problem that urgently needs to be solved. Based on social learning and dynamic competition theories, this study takes Shanghai-Shenzhen A-share listed companies from 2011 to 2021 as research samples, empirically tests whether there is a peer effect in the ESG performance of listed companies in China, and examines the generation mechanism and influencing factors of the peer effect in the ESG performance of enterprises. The results show that: (i) There is an industry and regional peer effect on the ESG performance of enterprises, where the average ESG performance of other enterprises in the same industry and region, except for the focus enterprise, significantly affects the ESG performance of the focus enterprise.This core conclusion still holds true after robustness tests such as instrumental variable method, propensity score matching method, and first-order difference method to eliminate endogeneity issues, replace key measurement indicators, and control for macro factors. (ii) The mechanism analysis results show that the “information learning” and “competitive pressure” mechanisms promote the peer effect of ESG performance. (iii) Further research has found that institutional investors’ attention and government environmental regulations positively and significantly impact the peer effect of corporate ESG performance. (iv) Heterogeneity analysis shows that the ESG performance peer effect is more significant for large-scale, eastern, and state-owned enterprises than for small-scale, central, western, and non-state-owned enterprises.

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}
