In the face of escalating urbanization and a dwindling rural populace in China, reconstructing rural settlements to enhance public service accessibility has become a fundamental strategy for achieving the SDGs in rural areas. However, few studies have examined the optimal methods for rural settlement reconstruction that ensure accessible and equitable public services while considering multiple existing facilities and service provisions. This paper focuses on rural settlement reconstruction in the context of the SDGs, employing an inverted MCLP-CC (maximal coverage location problem for complementary coverage) model to identify optimal rural settlements and a rank-based method for their relocation. Conducted in Changyuan, a county-level city in Henan Province, China, this study observed significant enhancements in both accessibility and equity following rural settlement reconstruction by utilizing the MH3SFCA (modified Huff 3-step floating catchment area) and the spatial Lorenz curve method. Remarkably, these improvements were achieved without the addition of new facilities, with the accessibility increasing by 44.21 %, 4.97 %, and 3.11 %; Gini coefficients decreasing by 19.53 %, 1.64 %, and 3.18 %; Ricci-Schutz coefficients decreasing by 21.09 %, 2.09 %, and 4.33 % for educational, medical, and cultural and sports facilities, respectively. It indicated that rural settlement reconstruction can bolster the accessibility and equity of public services by leveraging existing facilities. This paper provides a new framework for stakeholders to better reconstruct rural settlements and promote sustainable development in rural areas in China.</div></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"6 1","pages":"Article 100215"},"PeriodicalIF":8.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143139318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

This study aims to enhance the accuracy of the SDG11.3.1 evaluation and explore the impact of varying precision levels in urban built-up area on the indicator’s assessment outcomes. We developed an algorithm to generate accurate urban built-up area data products based on China’s Geographical Condition Monitoring data with a 2 m resolution. The study evaluates urban land-use efficiency in China from 2015 to 2020 across different geographical units using both the research product and data derived from other studies utilizing medium and low-resolution imagery. The results indicate: (1) A significant improvement in the accuracy of our urban built-up area data, with the SDG11.3.1 evaluation results demonstrating a more precise reflection of spatiotemporal characteristics. The indicator shows a positive correlation with the accuracy level of the built-up area data; (2) From 2015 to 2020, Chinese prefecture-level cities have undergone faster urbanization in terms of land expansion relative to population growth, leading to less optimal land resource utilization. Only in extra-large cities does urban population growth show a relatively balanced pattern. However, urban population growth in other regions and cities of various sizes lags behind land urbanization. Notably, Northeast China and small to medium cities encounter significant challenges in urban population growth. The comprehensive framework developed for evaluating SDG11.3.1 with high-precision urban built-up area data can be adapted to different national regions, yielding more accurate SDG11.3.1 outcomes. Our urban area and built-up area data products provide crucial inputs for calculating at least four indicators related to SDG11.</div></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"6 1","pages":"Article 100210"},"PeriodicalIF":8.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143139300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Drawing on a perspective of systems, this study compiles a panel dataset of 832 nationally designated poverty-stricken counties in China from 2013 to 2020 and employ the coupling coordination degree model to examine the coupling and coordination relationships among economic, social, and environmental systems in the PAC. We find that during the TPA period, the socioeconomic level developed rapidly, while the environmental quality was slightly improved in the PAC. The TPA strategy promotes the coordinated development of social, economic, and ecological systems in the PAC, shifting the relationship between human and environment from imbalance to coordination.

Rural households face strong barriers in adaption, and food production is seriously threatened. Current methods for increasing household adaptability take a holistic point of view, but do not accurately identify groups experiencing different adaptive barriers. To better identify different barriers, this paper examines natural, economic, cognitive, and technical barriers. A total of 17 indicators were selected to comprehensively evaluate the degree of barriers to crops adaptation in response to ECEs. Key factors were further analyzed to identify paths to break down the barriers. The results showed the following. (1) Natural barriers were present at the highest degree, economic barriers appear to be smallest, and the overall barriers were biased towards the lower quartile. 10.82 % of the households with the highest barriers. (2) 67.38 % of households report taking adaptive measures in crops production. The increase of the barriers leads to an increase and then a decrease in the possibility of adaptive behavior. (3) Addressing technical barriers is key to rapidly increasing household adaptive behavior in response to ECEs. The study provides recommendations for local governments to improve household adaptation behavior from two perspectives: short-term and long-term optimization pathways. This study can help governments quickly locate households with different classes of barriers, and propose more targeted adaptation policies.

Using multisource remote sensing data, we quantified and differentiated the direct and indirect impacts of urbanization on the carbon sequestration capacity of vegetation in 508 large urban areas globally from 2000 to 2020. The results revealed that the direct impacts of urbanization were generally negative. However, 446 cities experienced an indirect enhancement in vegetation carbon sequestration capacity during urbanization, averaging 19.6 % globally and offsetting 14.7 % of the direct loss due to urbanization. These positive indirect effects were most pronounced in environments with limited hydrothermal conditions and increased most in densely populated temperate and cold regions. Furthermore, indirect impacts were closely related to urbanization intensity, human footprint, and level of urban development.

A study was conducted in La Rioja (Iberian System, Spain), comparing three post-abandonment management strategies: secondary succession, forest management, and shrub clearing and extensive grazing. These strategies were analysed in two types of soil environments (acid and alkaline) and for two depth ranges (0–20 cm and 20–40 cm). Laboratory analyses were performed on aggregate stability and soil organic carbon fractionation with regard to three aggregate sizes (&lt; 2 mm, 2–5 mm, &gt; 5 mm) and three density fractions (free labile, occluded, and heavy fraction). The results showed that: 1) SOC content in aggregates &lt; 2 mm (relative to total SOC) increases with shrub clearing and grazing strategy in acid environments; 2) aggregate stability benefits from the implementation of afforestation in acid environments and from all three study strategies in alkaline ones; 3) in acid environments, the percentage of labile fractions (free and occluded) in afforested sites is significantly higher compared with shrubland, while in alkaline environments, recalcitrant SOC is significantly higher in shrub clearing sites.
