The RF outperformed the other models (AUC = 0.89), identifying the central and western regions as warning erosion zones. Breakpoint analysis revealed abrupt changes in NDVI and NDSI (2013), while early warning signals (autocorrelation, variance, and skewness) indicated an escalating erosion warning, particularly near wetlands and rainfed fields.

In the Africa Sahel region, as well as the largest ecological project in Africa——The Green Great Wall, characterized by diverse and dynamic ecosystems, the quantification of vegetation degradation and NPP variability remains limited and uncertain. Therefore, this study provides substantiating evidence to support the enhancement and preservation of vegetative ecosystems in the Sahel region by analyzing spatial and temporal variations in NPP and its driving factors from 2001 to 2020. The Theil-Sen median and the Mann-Kendall significance test were employed to evaluate the NPP spatio-temporal patterns, while the geographical detector model was implemented to measure the influence of environmental variables within the Great Green Wall corridor. We found that the NPP exhibited an upward trend, with 121.97 gC m⁻² annual average between 2001 and 2020. Over the past two decades of the Green Great Wall Project, approximately 40 % of the region exhibited an increase in NPP, 7 % experienced a decline, while 53 % remained desert or bare land. Spatially, the highest observed NPP was recorded in Ethiopia at 556.23 gC m⁻² yr⁻¹, while the lowest value observed was in Niger at 0.43 gC m⁻² yr⁻¹. The geographical detector analysis indicated that temperature and precipitation emerged as the dominant climatic driver of NPP variability, while interaction analysis revealed that the combined influence of precipitation and temperature had the strongest effect on NPP dynamics during the study period.

Remote sensing technologies offer scalable and non-destructive means to monitor forage productivity, with optical sensors limited by cloud cover and dense vegetation saturation. Synthetic Aperture Radar (SAR), particularly from the Sentinel-1 constellation, provides all-weather, high-resolution data capable of capturing structural and moisture-related vegetation attributes. This review evaluates the potential of Sentinel-1 SAR data for assessing and monitoring forage productivity in rangeland ecosystems. It highlights recent applications demonstrating Sentinel-1's effectiveness in forage productivity estimation and its integration with optical sensors like Sentinel-2 to enhance monitoring accuracy. Despite its advantages, challenges such as spatial resolution constraints, ecological sensitivity, and complex data processing impede full operational deployment. Future directions emphasize advanced data fusion techniques, machine learning approaches, and enhanced preprocessing algorithms to optimize Sentinel-1's utility. Integrating SAR with optical datasets promises to facilitate scalable, cost-effective, and reliable rangeland management strategies, supporting sustainable forage utilization and ecosystem resilience. Therefore, governments, the private sector, and NGOs should invest in Earth Observation infrastructure and capacity-building to translate remote sensing into actionable policies that promote sustainable rangeland management, climate change adaptation, and food security.</div></div>","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":"232 ","pages":"Article 105494"},"PeriodicalIF":2.5,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, sustainable soil management practices are a valuable tool to enhance the resilience of these areas as they can provide environmental benefits while ensuring fiber and food production. Among these practices, biochar use has gained recent attention due to its potential to enhance soil health; however, there is a lack of studies that synthesize the existing published data to guide future research. Therefore, we performed a bibliometric review to assess the current research status of soil health studies on biochar use in dryland soils. A total of 38 documents published between 2013 and 2024 were selected from the Web of Science and Scopus databases to be included in our analysis. Our results show that China leads in the number of publications, followed by Pakistan and Iran, which highlights the existence of research gaps in sub-Saharan Africa, Latin America, and parts of the Middle East and Europe. The most commonly evaluated properties in these studies to assess soil health were pH and phosphorus for chemical-associated parameters, and soil organic carbon and bulk density for biological and physical attributes, respectively. Physical parameters were the least commonly evaluated by the soil health studies with biochar application in drylands, despite their relevance. Research in the area highlights the overall potential of biochar to increase key parameters associated with land conservation in dry areas, such as nutrient availability, water retention, carbon sequestration, and crop productivity. However, research conducted on this matter remains limited and unevenly distributed. We recommend that future studies should address regional gaps and explore long-term effects under field conditions to enhance the current understanding of the benefits associated with biochar use in drylands.</div></div>","PeriodicalId":51080,"journal":{"name":"Journal of Arid Environments","volume":"232 ","pages":"Article 105490"},"PeriodicalIF":2.5,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process-response dynamics were investigated using quartz grain exoscopy (SEM-EDS) as a primary indicator. The analysis reveals a polyphasic history where subsequent pedogenic processes overprint primary geomorphic signatures. The initial state of the parent material is defined by a dominant suite of aeolian microtextures, including high-gloss polish and mechanical impact marks, indicative of prolonged transport in a mobile dune system. This primary surface is consistently altered by features diagnostic of incipient pedogenesis, such as chemical dissolution etching and authigenic growth of complex iron- and chlorine-rich aluminosilicate precipitates. Significantly, the recent, widespread expansion of irrigated agriculture provides a powerful modern analogue for the natural arid-humid cycles of the Quaternary.The seasonal, human-induced humidification of the sandy substrate creates the precise conditions required for these chemical alteration processes.
