Landsat imagery from 2000, 2010, 2020, and 2024 was classified into barren land, built‐up areas, forest areas, and water bodies using the Maximum Likelihood Classifier. In 2000, barren land dominated with 53.23%, followed by forests at 42.54%, built‐up areas at 3.75%, and water bodies at 0.48%. By 2024, forests expanded to 51.67%, barren land decreased to 33.16%, built‐up areas grew significantly to 14.55%, and water bodies increased slightly to 0.63%. The Shannon Entropy Index was calculated based on proximity to the city center and major road networks, dividing the study area into zones. Results reveal a rising normalized Shannon Entropy Index for the city center (H<jats:sub>C</jats:sub>′) and main road (H<jats:sub>R</jats:sub>′), with values of 0.978 and 0.58 in 2024, reflecting increased urban fragmentation. Zones 8 and 16 exhibited the highest spatial dispersion (0.96), indicating irregular development patterns and outward expansion. In 2000, the Tehri region was classified as type D. Over the years, it has mostly shifted to type B, showing more dispersed and possibly unsustainable growth. We advocate for a comprehensive space utilization control strategy that integrates the city center and the peri‐urban area. This research demonstrates the utility of the Shannon Entropy Index in identifying potential zones of unsustainable development in hilly regions and offers a replicable framework for other areas with similar topographical and developmental dynamics.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"72 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Urban Imbalance in China Driven by Land‐Based Financing: Challenges for Sustainable Resource Management","authors":"Miaoyu Yuan, Chenlin Gan","doi":"10.1002/ldr.70064","DOIUrl":"https://doi.org/10.1002/ldr.70064","url":null,"abstract":"China's rapid urbanization process has been characterized by a pronounced mismatch between land urbanization and population urbanization. This paper provides a new perspective on the root causes of this divergence, identifying local government reliance on land‐based financing as a pivotal factor. A theoretical framework is constructed to explore both the direct pathways and indirect mechanisms through which land financing contributes to this urbanization disequilibrium. Based on panel data from 31 provincial‐level regions across China from 2000 to 2017, the study empirically validates the framework using a mediating effect model. The findings indicate that land financing directly promotes the physical expansion of urban areas, resulting in spatial growth that outpaces demographic changes. Indirectly, land financing alters internal migration patterns through three main channels: the land expansion channel, the population attraction channel, and the population displacement channel. These channels are further influenced by variables such as urban service provision, urban–rural income disparities, and escalating urban housing costs. Furthermore, the paper differentiates the consequences of two land financing approaches: land conveyance financing (LCF) and land debt financing (LDF). Results show that while LCF plays a strong role in driving urban growth, it exacerbates income inequality; in contrast, LDF increases housing prices, hampers service efficiency, and exhibits a delayed effect on the imbalance in urbanization. This study underlines the systemic risks linked to excessive dependence on land‐centered financing and emphasizes the urgency of reforming China's urban development model. Encouraging more sustainable land financing mechanisms is essential for achieving coordinated urbanization, reducing inequality, and safeguarding long‐term environmental and resource security.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"37 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a case of ecological and socio‐economic consequences of oil extraction in the Chinese Loess Plateau. Findings indicate that, although oil development has stimulated local economic growth, it has simultaneously caused ecological degradation, including habitat fragmentation and biodiversity loss. Specifically, within the oilfields, all three plant strata—tree, shrub, and herb layers—show reduced species diversity and richness. Shannon indices are 0.61, 0.53, and 1.86 in the oilfields, compared to 0.65, 1.25, and 2.05 outside. Despite the economic benefits, oil extraction has exacerbated human‐wildlife conflicts (HWC), complicating socio‐ecological dynamics. Key trade‐offs between ecosystem and the intensifying human‐wildlife conflicts have been identified, creating a vicious cycle that threatens both environmental sustainability and community livelihoods. By analysing plant diversity, ecosystem characteristics, and records of human‐wildlife conflict (HWC) across different land‐use zones (core conservation areas, ecological transition zones, and human‐dominated areas), this study reveals that the ecological transition zone (ETZ) is particularly vulnerable to the combined pressures of resource exploitation and biodiversity conservation. The study further emphasises the necessity of integrated management strategies that incorporate ecological restoration, community engagement, and policy reform. Results highlight the importance of maintaining ecological resilience and developing adaptive management frameworks that balance development with ecological sustainability. The findings offer valuable insights for managing resource‐dependent regions globally, providing a model for reconciling economic development with environmental stewardship.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"40 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144577983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the spatio‐temporal dynamics of soil nitrogen and its reaction to both natural and anthropogenic factors is crucial for ensuring food security and environmental sustainability in the basin. This study utilized 3020 legacy soil samples and a Random Forest machine‐learning model to generate high‐resolution (250 m) soil nitrogen maps for the years 1996 and 2015 in this basin. The <jats:styled-content style=\"fixed-case\">GeoDetector</jats:styled-content> model was then used to analyze the factors influencing spatial and temporal variability of soil nitrogen. The results revealed an extensive decline in soil nitrogen density within the basin, from 503.02 g N m<jats:sup>−2</jats:sup> in 1996 to 466.61 g N m<jats:sup>−2</jats:sup> in 2015, indicating a decrease of approximately 7.24%, based on measurements at a 30 cm soil depth. The nitrogen stock decreased from 102.20 Tg N to 95.60 Tg N, resulting in a 6.60 Tg N decline, equivalent to an economic loss of 21.52 billion <jats:styled-content style=\"fixed-case\">USD</jats:styled-content>. Croplands accounted for 55.30% of this loss, or 3.65 Tg N. Forests exhibited the slowest decline in soil nitrogen density. However, a significant nitrogen decline occurred when forests were converted to other land uses. Deforestation has resulted in the loss of 2075.56 km<jats:sup>2</jats:sup> forest area, leading to a decline in soil nitrogen stock by 1.44 Tg N. Soil nitrogen in the basin showed notable spatiotemporal heterogeneity, with high‐value areas concentrated in the northeast and southwest, and low‐value areas mainly in the south. The variation in soil nitrogen in croplands is influenced by a combination of factors, including <jats:styled-content style=\"fixed-case\">GDP</jats:styled-content>, fertilizer consumption, temperature, and soil texture.

The objective of this study was to quantify the abundance of microbial functional genes associated with carbon (C), nitrogen (N), phosphorus (P), and sulfur (S) cycling over a 2‐year paddy field experiment after biochar application, employing a quantitative metagenomic sequencing with the spike‐in method. An increase in rice yield of 7.0% and 12.5% relative to the control was observed following biochar amendment over the 2 study years. The majority of soil microbial functional genes related to C, N, P, and S cycling exhibited higher abundances in soils amended with biochar. Notably, genes associated with the Wood‐Ljungdahl pathway, Calvin‐Benson‐Bassham cycle, and denitrification increased by 18.5%–197.4%, 25.9%–116.0%, and 5.1%–405.3% over 2 years. Gene responsible for P regulators increased approximately 10.5%–109.6%, while the assimilatory sulfate reduction process exhibited an increase of 12.7%–246.0%. Random forest highlighted key biogeochemical processes (e.g., C degradation, tricarboxylic acid cycle, and dissimilatory N reduction) as potential contributors to improving rice yields. Biochar amendment led to the formation of a more complex gene co‐occurrence network, as exposed by network analysis. Collectively, these findings underscore that biochar application may consequently enhance microbial functional capacity in paddy soils, fostering improved agroecosystem functions.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"47 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the status of ecosystem services sustainability (ESS) is crucial for achieving optimal ecosystem management. However, the understanding of the state, relationships, and driving mechanisms of ESS across scales remains limited. The essence of ESS is that the natural supply of ES meets current social demand without affecting later consumption. Therefore, we attempted to analyze the multi‐scale ESS and its drivers in the South China Karst region from the ES supply and demand perspective. From the results of the study, the sustainability of habitat quality (HQ) and carbon sequestration (CS) declined, while water yield (WY), soil conservation (SC), and food provision (FP) were enhanced, and the magnitude of change at the watershed scale was relatively gradual. The distribution patterns of ESS were similar at the county and watershed scales, but there were significant differences in the spatial clustering of hot and cold spots. The trade‐offs and synergies of ESS migrate with time and spatial scale, with counties dominated by competing trade‐offs and watersheds dominated by mutually reinforcing synergies. Social and terrain factors primarily influence HQ, while SC and CS are mainly driven by vegetation and social factors. Whereas WY is more controlled by climatic factors, especially most influenced by precipitation. Climate and terrain factors are the dominant factors limiting the sustainability of FP. Among the mediating effects, there is a need to focus on vegetation and social factor interaction processes, as positive indirect effects dominate them. On the contrary, the interactive processes of climate and terrain need to be guarded against, as they always have strong negative indirect effects, especially at the watershed scale. In the future practice of ecological management, we should strengthen multi‐scale management and actively promote synergistic management between supply and demand to resolve conflicts between multiple objectives and realize a win‐win situation.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"8 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144566014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We proposed a framework of regional integrated water security pattern of “resource supply—environmental protection—disaster prevention”, then applied this framework to Shenzhen City, China. The results showed 7.13 million people (40.73% of Shenzhen's population) lived within the water disaster prevention pattern. The overlapped area of security patterns of water resource, environment, and disaster only accounted for 14.99% of the study area, highlighting significantly spatial mismatches. Objective water security zoning required targeted spatial conservation management. The integrated water security pattern showed the largest distribution areas in the Bao'an and Longgang Districts. Moreover, Shenzhen's water security pattern matched well with urban blue line (88.57%) and basic ecological control line (69.45%), which was a supplement to the local existing spatial conservation planning. The proposed framework is applicable to low‐lying and humid regions, offering a systematic approach to constructing water security patterns from theory to practice.
