Soil erosion is a critical challenge threatening agricultural productivity and environmental sustainability globally. This study presents the first estimation of water-induced soil loss in Ordu province, Turkey, using Revised Universal Loss Equation (RUSLE) integrated with Google Earth Engine (GEE) Geographic Information System (GIS) technologies. Our analysis provides spatial insights into patterns across region, revealing that rates range from 0–5 t/ha/yr stable areas to over 200 severely eroded regions. The mean rate estimated at 12.58 t/ha/yr. identified LS factor (slope length steepness) as most significant contributor erosion, followed by R (rainfall erosivity). These findings offer valuable dynamics, supporting sustainable management practices informing control strategies. results contribute land use planning policy development aimed mitigating degradation enhancing resilience province.

The Revised Universal Soil Loss Equation (RUSLE) is the most widely used global soil erosion model. poor performance of RUSLE solely dependent on inherent structure model to account for phenomena under varying topographic and climatic conditions. Considering extensive application model, it high time in research identify suitability In this context, a global-scale review was carried out best possible conditions its reliable where yielded performance. still frequently operational simulation despite numerous deficiencies, weaknesses, limitations. Nevertheless, over large ungauged areas remains real challenge due non-availability quality required inputs.

Studying the relationship between human activities and soil erosion on a regional scale is of great significance for macro-decision-making in prevention control. The entropy weight method RUSLE model are used to analyze spatiotemporal variation activity intensity (HAI) Weihe River Basin (WRB) from 2005 2020. Through geographic detectors four-quadrant model, impact various driving factors coupling degree human–land studied. results showed: (1) During past 15 years, moderate, high, strong, severe areas WRB decreased by 9.88%, 35.89%, 45.17%, 70.05%, respectively. ratio historical sand transport modulus result 0.83, indicating that obtained can be further analysis. (2) Slight weak degrees account 80% northwest region. high strong regions mainly distributed Shaanxi section, accounting 3% total basin. (3) constantly strengthening, joint effect pop crop main reason slowdown spatial differences erosion. This indicates ecological environment became stable. These findings contribute acting as references water conservation management promote harmonious humans environment.

The spatial-temporal differentiation characteristics and driving mechanisms of ecosystem services are great significance for optimizing the pattern land spatial protection realizing regional sustainable development. Existing studies seldom consider segmental influence mechanism various influencing factors on different levels service value (ESV). Therefore, this paper analyzes temporal evolution ESV in semiarid regions through an improved evaluation model. panel quantile regression (SPQR) model was introduced to explore relationship between types intervals. results showed following: (1) changes Baotou City from 2000 2018 tended be stable, but intensified. aggregation feature low-ESV region is significant gradually expanding. (2) Precipitation dominant factor increasing each interval, temperature had a negative impact area.

The present study aims to delineate the groundwater potential zones (GWPZ) in Boudinar Basin using geospatial techniques and through an analytical hierarchal process (AHP) method. For multi criteria decision analysis, fifteen thematic layers were integrated into a geographic information system (GIS) environment. In this each layer is calculated for normalized weights. Furthermore, consistency index ratio ensure that result was significant reliable. GWPZ map has been categorized three classes: poor (50.82%), moderate (49.06%), good (<1.00%). To compare result, we used four other scenarios of GWPZ. Two them are most similar our result. Finally, predictive production management strategies long-term sustainability highly needed.

ABSTRACT The task of soil erosion estimation received a significant push by integrating remote sensing and geographical information systems (GIS) with the Revised Universal Soil Loss Equation (RUSLE) in early 1990s due to its ease applicability. Topographic (LS) factor played quintessential role loss determination, especially for undulating regions. In most worldwide studies, topographic extracted from Digital Elevation Model (DEM) using “LS equations” failed account varying slopes before material joins stream or river. this study, slope length (L) steepness (S) derived without cutoff are compared analyzed hilltop mine. results reflect that LS and, ultimately, over‐estimated owing absence any limits on terrains when used conventionally GIS environment. mean estimated is 252.26 ton ha −1 year , whereas 332.81 conventional application same equation. overestimation was reduced 35% as per volume‐based validation study. Thus, study proves usefulness factor, which, date, has mostly been neglected research studies terrains. pattern also highlights negating impact vegetation steep slopes, cementing their Nature based Solution (NbS) dynamic landscapes like Mines.
