An innovative valuation framework is introduced that combines land use/cover change (LUCC) analysis, supply and demand matrices and Gini coefficient calculations to assess the supply and demand of ecosystem services (ES-S and ES-D). Unlike traditional static methods, this approach captures intricate spatial and temporal mismatches, offering new insights into the impacts of LUCC on ES balance within the framework of sustainable development goals (SDGs). Taking the Three Gorges Reservoir Area (TGRA) as a case study, the findings indicate a significant decrease in cultivated land, accompanied by expansion of forest and built-up area, driven by farmland-to-forest policies and urbanization. These shifts have improved the balance of provisioning and supporting services but have also intensified regional disparities, particularly in Chongqing, where demand outpaces supply. Furthermore, LUCC have altered the capacity of ecosystems in the TGRA to provide essential services, such as soil retention and water regulation, thereby supporting progress toward SDGs related to ecosystem sustainability. However, imbalances in cultural services persist, highlighting the need for targeted management strategies to optimize ES provision and support regional sustainability. This study underscores the importance of ongoing ES-S and ES-D assessments to inform sustainable land management policies in ecologically sensitive areas like the TGRA.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"35 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495779","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 phenomenon has been illustrated by several studies, mainly on the scale of individual countries. However, there is a noticeable lack of global-scale analyses examining how different aspects of land tenure affect ALCU. To address this gap, we have conducted a meta-analysis of 62 studies that provide quantitative insights into the effects of land tenure variables on ALCU. We used Comprehensive Meta-Analysis (CMA) software to extract data from original articles, including land tenure type (expressed as land farmed by its owner and land farmed by a tenant), legal status (titled land and untitled land), cadastral assignment (designated and not-designated agricultural land), and land ownership (private land and communal land). We have found significant effects of all these aspects of land tenure on ALCU. Land farmed by its owner was the most substantial factor protecting agricultural land from urbanization, with a 3.42% decrease in ALCU. We also observed a 2.97% decrease in ALCU on titled land, a 2.62% decrease on designated agricultural land, and a 1.85% decrease on land that was privately owned. The application of findings and implications for policymakers are substantial: (i) efforts to secure land tenure, especially in underinvested areas, can minimize the degradation of land resources and facilitate better farmland preservation, (ii) the support of owner-operated farming, land titles, private ownership of land, and designated agricultural land is conducive to sustainable farmland management, and (iii) the synergic effect of promoting land tenure security should be utilized to protect agricultural land from conversion to urban uses.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"305 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485965","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}

The Tarim Basin is the largest inland basin around the world, with saline land making up approximately 20% of its total area, while few research has been conducted on salt-affected soil carbon density and its distribution in the region. To identify the effect of soil salinity on soil carbon density, we collected 135 soil profiles (0–100 cm), and calculated the soil organic carbon density (SOCD), soil inorganic carbon density (SICD), soil total carbon density (STCD) and their distribution, and discussed their relationships with climate and soil physicochemical properties. Results showed that average STCD, SOCD, and SICD at 0–100 cm soil profile were 25.0, 3.7, and 21.3 kg C m⁻², respectively. SICD was approximately 6.30–9.04 times higher than SOCD. The vertical distribution of SOCD decreased with increasing soil depth, whereas STCD and SICD increased. Soil salinity had negative effects on STCD by reducing both SOCD and SICD, with the negative impact increasing with salinity degrees. Compared to non-salinity, STCD at 0–100 cm soil profile decreased by 10.5%, 7.0% and 10.5% under light, moderate, and severe salinity, respectively. Random forest analysis indicated that soil total nitrogen content (STN) and soil bulk density (BD) were the most important predictor variables for estimating SOCD and SICD. Soil salinity had significant negative correlation with STN and BD, resulting in a negative effect on SOCD and SICD. Our findings emphasized that soil salinity reduced STCD mainly by reducing SICD, and the reduction in carbon stocks increased with increasing soil salinity degree. In addition, mitigation of the adverse effects of soil salinity on STC stocks could be considered by increasing STN content and soil bulk density.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"15 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485967","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}

Natural recovery, one of the most effective ways of landslide recovery, was studied by referring to vegetational structure, soils, and environmental variables and their correlations about 6 years after a landslide in Garhwal Himalayas. The study illustrated that a nutrient-deficient environment prevails in landslides. A total of 25 plant species were found with higher diversity and richness indices of herb species in disturbed sites than in undisturbed sites. The low values of similarity index between the landslide and control sites exhibit the impacts of environmental components on the recovery of vegetation on landslides. The correlation through redundancy analysis (RDA) reveals that the herb species are more inclined toward the higher landslide sites having high pH and low nutrient content, whereas the woody species are more oriented toward the middle landslide sites. It was also observed that <i>Alnus nepalensis</i> has a wide distributional range as it was placed near the center of the RDA biplot. There exists a research gap in apprehending the variations in soil carbon status, nutrient dynamics, and plant community structure following natural recovery along elevational gradients in landslides. The study indicates that the early stages of plant recovery following landslides are significantly influenced by abiotic environmental conditions associated with soil characteristics. This study also provides a reference for the recovery and restoration strategies in the landslide-affected regions. The recovery in landslides is a complex process; hence, further long-term studies should be continued to evaluate the spatio-temporal variations during succession in landslides and interactions between the biotic and abiotic components.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"209 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485966","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}

However, there are still research gaps on the interactive effects of P fertilizer application and straw incorporation on indigenous AMF in coastal saline–alkali land. Thus, this study aimed to assess several mycorrhizal features, the abundance, and the community composition of soil AMF in a field after a 4-year barley–cotton rotation. We also explored the roles of AMF play in enhancing cotton P uptake. The field was treated with five triple superphosphate levels (0, 22, 44, 66, and 88 kg ha⁻¹) and subjected to either straw incorporation or removal. The total P content of cotton increased with straw incorporation and increasing P application rates; however, the percentage of P partitioned to bolls, the boll capacity of the root system (BCR), and the boll loading of the root system (BLR) exhibited a trend of initially increasing followed by a decrease. The highest value was achieved when straw incorporation was combined with 44 kg P ha⁻¹. Besides, the root colonization by AMF, soil AMF abundance, and spore density were highest at 22 kg P ha⁻¹ without straw and 44 kg P ha⁻¹ in the straw incorporation treatment. Redundancy analysis (RDA) revealed that the observed community shift was primarily driven by the enhancement of rhizosphere soil pH and organic matter following straw incorporation. Overall, these findings showed that straw incorporation coupled with moderate P fertilizer created a favorable rhizosphere soil environment, which, in turn, enhanced rhizosphere soil AMF diversity and abundance, thereby improving cotton root production capacity and facilitating P distribution to reproductive organs. Our results suggested that the threshold of P fertilizer input can provide a basis for saving P fertilizer and effectively maintain agricultural ecosystems' AMF diversity and abundance in coastal saline–alkali land.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"71 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143470522","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 employs a comprehensive, feasible, generalized least squares model to empirically assess the impact of rural non‐agricultural employment (RNE) on EEFU, revealing variations across grain production areas in China. This study also analyzes the spatiotemporal distribution and convergence of EEFU in China from 1990 to 2020 by using the global undesired super‐efficiency slacks‐based measure model and convergence model. Findings indicate that RNE constantly increases; meanwhile, EEFU initially decreases and then increases, demonstrating absolute β convergence. Provinces with low EEFU present a “catch‐up” effect with those characterized by high EEFU. A U‐shaped relationship between RNE and EEFU is thus recognized: RNE in China generally reduces EEFU but enhances EEFU in major grain‐producing areas. However, this relationship weakens in primary grain‐marketing areas and balanced production‐marketing areas. To improve EEFU, China should provide agricultural outsourcing services for elderly and smallholder farmers, addressing labor shortages, insufficient technology utilization, and low efficiency, thus promoting environment‐friendly production practices. Expanding farmland to achieve economies of scale in farmland utilization is also important for improving EEFU.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"22 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462932","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 disruption in the dynamic equilibrium of the river is attributed to sediment accumulation upstream of the reservoir's dam, limited sediment outflow from the reservoir, and increased downcutting downstream of the dam. Consequently, these alterations necessitate further human interference in natural environmental processes through the construction of various river engineering structures designed to reduce the intensity of downcutting. The purpose of the present study was to assess the impact of a small mountain reservoir and additional river regulation structures on the Wapienica River in southern Poland, focusing on the structural and functional connectivity of the river channel in terms of sediment transfer. This assessment was based on erosion and connectivity modeling, as well as field mapping. A high-resolution digital elevation model (HRDEM) was examined in the study along with survey data on suspended sediment accumulation sites along the river. The study utilized open-source tools, including SedInConnect for connectivity index (IC) calculation, and the Soil and Water Assessment Tool (SWAT) for ArcGIS software. It was found that the Wapienica reservoir permanently retains the floating material, making the likelihood of this material flowing out of the reservoir minimal. Within the reverse delta of the reservoir, the entire load of bottom material (sand) is also retained. Thicker bottom material (gravel, boulders) is deposited in the riverbed within the delta, leading to the shallowing of the bed upstream of the delta. These processes disrupt longitudinal connectivity. Six connectivity zones have been identified within the catchment. The first four are situated in the southern part of the catchment: strong connectivity, reduction, concrete channel, and damage area. The remaining two, situated in the northern part are: artificial channel and drainage channels. Each of the six zones is characterized by different sediments and river processes. It was demonstrated that a more detailed and more probably connectivity pattern for hillslopes and river channels may be obtained through the use of several tools and parameters at the same time (i.e., fieldwork, SWAT, IC).","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"2 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462490","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}

However, large-scale vegetation restoration will inevitably result in massive water resources consumption in arid and semi-arid regions, which will increase the risk of water security for regional social and economic development. How to safeguard the water resources required for socioeconomic development in the background of vegetation restoration and simultaneously maximize the benefits of water adaptation-sediment reduction-carbon enhancement on the Loess Plateau represents a critical scientific challenge to be addressed in future ecological construction efforts. Based on this, this study aimed at the Yanhe River Basin (YRB), a representative basin for vegetation restoration on the Loess Plateau, and creatively proposed a vegetation optimization regulation method with water supply capacity as the constraint while aiming to maximize the benefits of carbon sequestration and sediment reduction. Results indicated that under the current vegetation pattern, water deficit in the YRB by 2030 would be 27.22% and 3.00% under the SSP2-4.5 and SSP5-8.5 scenarios, respectively. By optimizing the original vegetation pattern—reducing high water-consuming vegetation, increasing drought-tolerant shrubs (797–1006 km²), and decreasing fractional vegetation coverage (FVC) by 4.00%–5.84% under the SSP2-4.5—the basin's water supply (W_s) would increase by 41.36%–44.13%, while net primary productivity (NPP) would decrease by 1.83%–2.39% and soil erosion (SED) would increase by 2.86%–3.71%. Under the SSP5-8.5 scenario, by increasing FVC (6.03%–8.00%), increasing drought-tolerant shrubs (813–1295 km²), and reducing forest and grassland, the water resources required for basin's socioeconomic development would be guaranteed (1.60 × 10⁸m³–1.61 × 10⁸ m³). The optimized vegetation scheme also significantly increased NPP (13.38%–14.64%) and decreased SED (13.28%–15.24%) under the SSP5-8.5.

The regional warming and humidification of the climate caused by global warming have brought uncertainty to the desertification development trend of the Qinghai-Tibetan Plateau. Therefore, it is crucial to pay close attention to the status and trends of desertification. In this study, Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation indexes, albedo and topsoil grain size index (TGSI) data for the Qinghai-Tibetan Plateau were collected by Google Earth Engine (GEE) from 2000 to 2020, established an optimal monitoring model for desertification on the Qinghai-Tibetan Plateau using the feature space, and analyzed the spatiotemporal evolution patterns. The results show that the albedo-modified soil-adjusted vegetation index (MSAVI) model is the most suitable for desertification monitoring in the Qinghai-Tibetan Plateau region, with an overall accuracy of 88.07%. Generally, desertification on the Qinghai-Tibetan Plateau shows an overall improving trend from 2000 to 2020, with the proportion of non-desertification areas rising from 61% in 2000 to 70% in 2020. The desertification situation in most parts of the Qinghai-Tibetan Plateau shows a worsening rebound from 2010 to 2015, and then improves. There are constant transitions between adjacent levels of desertification land, with more active low desertification land and more stable bare desert. This study provides a simple, feasible, and highly accurate desertification monitoring method for the Qinghai-Tibetan Plateau region, and provides important data support for the driving mechanism and control measures of desertification.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"81 1 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143462493","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}

However, soil carbon has been less studied in sand‐based river valley of arid and semi‐arid regions. This study was to mainly understand the capacity of soil carbon accumulation in sand‐based Xilin River valley in arid and semi‐arid Mongolia Plateau by comparing with the surrounding steppe and sandland. We found that soil carbon storage per unit area sequenced in steppe &gt; meadow &gt; sandland, which was inversely associated with soil sand fraction. Soil carbon storage in river valley meadow was close to the mean value in three landforms, without significant difference between both. River valley wetland and water body were also synthesized at weak soil carbon accumulation. These results can be concluded that soil carbon accumulation in the low‐lying Xilin River valley had no predominance relative to the surrounding high‐lying landforms. Sand‐based soils are more aerated than loamy and clayey soils, and their organic carbon is more easily decomposed. Again, sand‐based soils are mainly composed of silicate; their low quantities of organic and inorganic carbons are further mineralized and dissolved by water erosion in the river valley, respectively. Furthermore, low plant productivity, arid and semi‐arid climate, weak sediment transport, and deposition cannot efficiently promote soil carbon accumulation. We suggest that river valley cannot be overestimated in evaluating the storage of soil carbon in arid and semi‐arid regions.","PeriodicalId":203,"journal":{"name":"Land Degradation & Development","volume":"181 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143451964","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}
