Pisha sandstone could be used to maintain the water and nutrients in sandy soil due to the presence of montmorillonite, but the impacts of application methods (patterns and levels) on N leaching loss remain unclear. Leaching experiments were conducted to investigate the impacts of Pisha sandstone application patterns and levels on N leaching loss. Soil columns were constructed, including four application patterns (U, upper layer in soil column; M, middle layer; L, lower layer; Mix, mixing with sandy soil) and three application levels (10%, 30%, 50%, mass ratio). Results indicated that not all treatments showed a decrease in N leaching from sandy soil, and the application patterns had a higher effect than application levels. Compared with the sandy soil, the Mix application pattern presented the best impact in reducing N leaching (18.8%—28.3%) and could reduce more leaching N by increasing application levels. The L pattern effectively reduced N leaching loss (3.5%—20.2%) and water drainage loss (12%—33.8%). A cautious attitude should be adopted in selecting U and M patterns due to the risk of increasing N leaching loss. The reasonable use of Pisha sandstone was helpful in reducing N leaching loss from sandy soil. More fieldwork is needed to extend our findings in the future.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"24 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640761","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":"Automatic Detection for Cropland Destruction and Reclamation in Coal‐Grain Composite Region Using Long‐Term Landsat Imagery","authors":"Kegui Jiang, Keming Yang, Mengting Gao, Xinyang Chen, Lishun Peng, Xinru Gu","doi":"10.1002/ldr.5575","DOIUrl":"https://doi.org/10.1002/ldr.5575","url":null,"abstract":"The eastern plains of China are home to numerous “coal‐grain composite regions,” where extensive underground coal mining has led to widespread land subsidence and cropland destruction, profoundly affecting regional ecological environments, agricultural production, and food security. This study proposes an automatic method for detecting cropland destruction and reclamation. The Normalized Difference Vegetation Index (NDVI) derived from long‐term Landsat imagery was selected as the primary factor. First, by extracting a substantial number of NDVI samples from the mining areas, the threshold for cropland destruction due to mining disturbances was determined. Various types and scales of NDVI change templates were constructed based on the mechanisms of cropland disturbance. Subsequently, the Fast Dynamic Time Warping algorithm was employed to match the time‐series curves and identify disturbance types, along with formulating detection rule for the year and magnitude of the cropland disturbance. Finally, patch indicators for disturbed croplands were established, and a random forest model was utilized to eliminate the disturbance noise induced by anthropogenic construction. The proposed method was applied to the Huaibei coal base, mapping cropland destruction and reclamation due to mining activities from 1987 to 2022, with overall accuracies of 0.85 and 0.81, respectively. This study revealed that the total area of cropland destroyed by mining activities amounted to 10179.71 ha during the monitoring period. From 1987 to 2005, the area of cropland destruction was small, accounting for 27.51% of the entire period. Between 2006 and 2018, the area of cropland destruction significantly increased, totaling 6102.01 ha and accounting for 59.94% of the entire period. The area of cropland destruction rapidly decreased and stabilized after 2018. Reclamation efforts began roughly in 1995, achieving a total reclaimed area of 2734.83 ha, with a reclamation rate of 26.86%. This study provides a crucial reference for monitoring the environmental impacts of mining and assessing the effectiveness of ecological restoration.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"213 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143618383","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}

Despite being a fragile and highly biodiverse ecosystem, little is known about the magnitude, spatial distribution, and drivers of heavy metal contamination in this reserve. Soil samples were collected at a depth of 0 to 10 cm from mangrove areas (MANg), salt marshes (SMe), and dry forests (Df) to assess concentrations of copper (Cu), manganese (Mn), iron (Fe), zinc (Zn), lead (Pb), and chromium (Cr) and their correlation with physicochemical properties. Analytical methods included one‐way ANOVA, Pearson correlation, cluster analysis (CA), and the application of the geo‐accumulation index (<jats:italic>Igeo</jats:italic>) and pollution load index (<jats:italic>PLI</jats:italic>) to quantify contamination levels. The results reveal elevated concentrations of heavy metals in MANg, SMe, and the southern dry forest (Df‐S5), exceeding thresholds reported in previous studies. Notably, Zn and Pb contamination levels range from high to very high across the reserve, with MANg soils being the most impacted by all metals studied. The accumulation patterns are closely linked to soil properties such as silt and clay content, porosity, pH, and organic matter, which influence metal retention and mobility. This contamination is primarily attributed to anthropogenic activities, including shrimp farming, conventional agriculture, and pollutants originating from mining, domestic, and industrial discharges from nearby urban areas. These findings underscore the urgent need for targeted restoration and conservation measures to safeguard the reserve's biodiversity and ecosystem services. They also highlight the necessity for updated regulations and mitigation strategies to manage contamination effectively, offering a foundation for sustainable management practices in the AERv and other protected areas in Ecuador.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"59 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608030","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}

According to the Regional Information System (SIR) of the Governor's Office of Huila, the area planted annually with achira in the department for 2020 was 82.3 ha, and the local demand for starch (400 tons/year) is imported from other departments (Cundinamarca and Nariño). Beyond its economic potential, achira contributes to ecosystem services. Its organic management, limited to cultural practices, helps mitigate pollinator population decline, particularly among wild bees. The problems caused by the growth of areas planted in coffee and other conventionally managed crops make it crucial to better understand the relationship between biodiversity and agricultural production; therefore, it is imperative to develop sustainable management strategies that promote the conservation of floral visitors, pollinators, and biodiversity in general. This study aims to characterize the diversity of floral visitors in Achira (<jats:styled-content style=\"fixed-case\"><jats:italic>Canna indica</jats:italic></jats:styled-content>) crops across different altitudinal zones in the department of Huila, characterizing the study area, identifying native bees and floral visitors in the crop through fieldwork conducted on three farms located in the municipalities of Garzón and San Agustín. The variations in altitudinal zones may affect the distribution of native bee species and other visitors, reducing their abundance. Further studies are recommended to establish a direct correlation between altitude and floral visitor diversity.

This degradation is concerning because many of these trails are located in protected natural areas, which aim to conserve natural resources and associated biodiversity. Concurrently, ecosystems worldwide have also been experiencing increased degradation, prompting the United Nations to declare this the Decade of Ecosystem Restoration. In this context, through a systematic review of the scientific literature, our study identifies significant gaps in knowledge regarding the management of degraded trails in protected natural areas worldwide. We observed that the number of research studies has been growing, particularly in the last decade, and is concentrated in countries with developed economies and by researchers from these countries. Notably, while the literature on trail degradation is abundant, there is a pronounced scarcity of empirical research focusing on strategies for the reversal of such degradation. Moreover, the variability in the use of terms such as restoration, recovery, and rehabilitation across studies indicates a lack of consensus that may hinder effective communication and implementation of strategies to address the reversal of trail degradation. Thus, the strength of this research lies in its ability to bridge existing gaps by providing a comprehensive analysis of current terminologies and methodologies. By clarifying the terms' meanings, this study enhances their application in trail management. This enhancement, in turn, boosts management practices and aids in the global effort to restore degraded ecosystems. Not only does this work map out the existing research landscape, but it also underscores the urgent need for more targeted empirical studies that could inform practical, effective strategies for trail restoration in protected natural areas.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"19 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619042","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}

Re‐examining the contribution of regional economic, ecological, and social development to the common creation of well‐being, analyzing their deep connections, will help us understand the multidimensional concepts and processes of development, and provide ideas for further promoting the construction of a more equitable and sustainable world. China is moving from comprehensive prosperity to common prosperity, and the continuous improvement of sustainable well‐being provides effective samples for our research. This study focuses on 46 counties in the Qinba Mountains Areas of China and constructs a coupled performance indicator system for sustainable well‐being in mountain villages. The Super SBM model is used to evaluate the matching performance of input and output factors, with Economic capital, Ecological capital, and Social capital as explanatory variables and Sustainable Happiness Index as the expected output. Research has found that: (1) There is a mismatch between the input and output factors of sustainable well‐being in the Qinba Mountain Areas, and management techniques are a key factor hindering the improvement of the coupling performance level of sustainable well‐being in the Qinba Mountain Areas; (2) The coupling performance level of sustainable happiness in the Qinba Mountain Areas is showing a downward trend, and only adjusting the input–output relationship by about 1.02% can achieve optimization and growth in performance level; (3) There is a significant shortage of input factors, with 87% of counties experiencing insufficient economic capital, about 76% experiencing insufficient arable land, and 41% experiencing insufficient social capital. In order to solve the above problems, it is necessary to strengthen the level of sustainable management in the ecological, economic, and social integration of the counties, respectively.

Systematic and forward-looking analyses of land use changes (LUCs) and ecological risks in Asia's arid zones, particularly the urban agglomeration on the northern slope of the Tianshan Mountains (UANSTM), remained limited. Herein, the LUCs in UANSTM under four scenarios, including the ecology-economy balanced development scenario (EES), ecological protection scenario (EPS), economic development scenario (EDS), and natural development scenario (NDS) in 2030, was predicted by employing the PLUS model and the multi-objective programming (MOP) model. Then, an evaluation system was developed from the dimensions of urban expansion, ecological risk, food demand, and ecological degradation to assess the corresponding ecological risk in each case. The results showed that: (1) Under each scenario, desert bare land and grassland were found to be the main LU modes in UANSTM, with a significant increase in cultivated land and negligible change in water and forest; (2) the grassland area decreased under the NDS scenario, while the areas of grassland, forest land, cultivated land, and construction land increased under other scenarios, especially from unused land and grassland; (3) LU-induced ecological risks under these scenarios showed similarities, with overall high ecological risks. Among them, 52.04% of the areas were found to be at high and relatively high-risk levels, and only 2.97% were at low-risk levels.

However, it remains unclear how microbial resource limitation and C turnover dynamics respond to P availability under elevated N loads in dryland ecosystems. To address this, we conducted a 7-year experiment in a desert steppe in northern China, applying a gradient of P additions (0–16 g P m⁻² year⁻¹) under conditions of N loading (atmospheric N deposition +5 g N m⁻² year⁻¹). Our aim was to investigate microbial nutrient limitations and their impact on microbial carbon use efficiency (CUE) based on stoichiometry theory. Our findings revealed that, under N loading, microbial metabolism in both the surface (0–10 cm) and subsurface (10–20 cm) layers of the topsoil was limited by both C and P. Interestingly, with increasing P addition, microbial C limitation initially increased and then decreased at the surface but remained unchanged in the subsurface. Under conditions of C limitation, P enrichment did not alleviate microbial P limitation in either soil layer. Surprisingly, the microbial communities in both the surface and subsurface layers maintained plastic stoichiometric homeostasis despite aggravated C:P and N:P imbalances. Furthermore, P enrichment decreased microbial CUE in both soil layers, with the surface experiencing the most significant decline. Further analysis showed that the factors driving microbial nutrient limitation and CUE varied between soil layers under P enrichment, with enhanced microbial C limitation strongly inhibiting CUE. Our study indicates that increased C limitation due to P enrichment can reduce CUE and exacerbate stoichiometric imbalances. This could potentially lead to greater C loss in N-enriched dryland soils.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"22 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600049","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}
