Assessing vulnerability to soil erosion based on fuzzy best worse multi-criteria decision-making method

Abstract Soil wearaway or erosion is the most significant environmental risk in agricultural land loss, and is widely recognized as a significant environmental risk worldwide. The lowest from the viewpoint of soil erosion rank was sub-watersheds 9, 14, 5, and 5 were the most vulnerable to soil erosion and sub-watershed 3 was the least susceptible, according to the results.

REMOTE MAPPING OF SOIL EROSION RISK IN ICELAND

Since the availability of free access satellite data, the use of remote-sensing based soil erosion assessment has been on increasing in recent years, and it has consistently been profitable. Here we suggest a solution that uses a Support Vector machine classification system and ground truth samples to calibrate the processed remote images over a specific region in order to automate the process for larger, less accessible regions. This solution is being developed for soil erosion studies of Iceland specifically using Sentinel 2 satellite data and local assessment data from Iceland's Soil Conservation Services department.

Understanding the impact of changes in land-use land-cover and rainfall patterns on soil erosion rates using the RUSLE model and GIS techniques: A study on the Nagavali River basin

Soil erosion is the most common form of land degradation, and it has become a global environmental problem that reduces soil quantity and water quality, which has been exacerbated by human-induced activities. The annual soil erosion rate in the NRB rose from 0 to 7857. 21 t/ha/yr in 1990 to 7857. 21 t/ha/yr by the year 2020, according to the study's average annual soil erosion rate of 0 to 2364. 46 t/yr in the year 1990 to 7857. 21 t/ha/yr. The area under the very severe erosion class increased dramatically from 4. 34 to 13. 97 percent between the years 1990 and 2020, according to a survey carried out by the spatial distribution of soil erosion risk classes.

Study of hanging valley in loess-paleosoil sediments with soil erosion assessment using nuclear and erosion potential methods

This paper is about soil erosion evaluation using two specific methods: the nuclear model and erosion potential technique, as well as Gavrilovic's method. The applied nuclear models were verified by comparison with the erosion potential model, which is the most comprehensive empirical model for erosion processes in torrent valleys. The obtained findings show a good fit with overall low values of average annual soil erosion rates in the investigation area, as shown by the table below.

Rates of Historical Anthropogenic Soil Erosion in the Midwestern United States

In most agricultural landscapes, the total amount of soil that has been eroded since the onset of farming is unknown, which prevents analysis of soil erosion trends. Native prairie remains have risen above surrounding farmland in the Midwestern United States, giving an opportunity to determine historical soil erosion rates. To forecast regional soil erosion integrated from the start of farming to the present, we used an association between the measured decrease in soil thickness and topographic curvature to map regional soil erosion. Our results show that a combination of soil erosion rates measured in the Midwestern United States is increasing, with the NRI and the DEP underestimating soil loss rates because they do not include tillage erosion, which is a process that has been demonstrated to be effective across the Midwestern United States.

Soil erosion in Qilian Mountain National Park: Dynamics and driving mechanisms

The risk of soil erosion has risen at a global level, according to the study's findings: The risk of soil erosion has risen noticeably. Here, we used the Revised Universal Soil Loss Equation to determine the soil erosion rate in QLMNP from 1982 to 2020. Despite the marginal decrease seen in the majority area in the majority area, the soil erosion rate averaged over QLMNP increased by 0. 13 t ha-1 yr-1 from 1982 to 2020. Our findings show that ecological initiatives are highly effective in reducing soil erosion attributed to climate change.

A Field Study for the Effects of Grass Cover, Rainfall Intensity and Slope Length on Soil Erosion in the Loess Plateau, China

Through simulation experiments, this research examined the effect of the slope length on soil erosion for various grass coverages and different rainfall intensities. Different slope lengths were significantly different in the change of soil loss. The trend of soil erosion altering with slope length is: under a grass cover of 0 or 30%, the soil erosion increased exponentially with increasing slope length. Compared to a slope length of 2 meters, longer slope lengths increased the erosion rate by 225 percent to 93 percent under different grass coverage techniques. According to the increase of rainfall intensity, grass cover and rainfall intensity change the trend of erosion with slope length, while slope length increases, and the negative effect of slope length decreases with slope length.

Study on the Characteristics of Soil Erosion in the Black Soil Area of Northeast China under Natural Rainfall Conditions: The Case of Sunjiagou Small Watershed

At present, the black soil area, where soil erosion is severe and the soil is in dire need of ecological restoration, is a critical issue. Nine runoff plots were developed in Bin County, the main area of soil erosion control, to track runoff and soil loss long-term, as shown by the erosion potential method for comparison. The soil loss rate of the cross ridge tillage and ecological restoration plots was less than the allowable soil loss rate. Soil loss rates in longitudinal ridge tillage can be much higher than those of bare ground under erosive storms. In the study area, the transition from longitudinal ridge tillage to cross ridge tillage on gentle slopes will effectively prevent soil erosion.

Exploring the Relationship between Cover Crop Adoption and Soil Erosion Severity: A Case Study from the Simcoe Watershed, Ontario, Canada

Runoff from agricultural fields during the non-growing season is a major contributor to phosphorous loading and decreasing water quality in Lake Simcoe, Ontario. Cover crops have the ability to reduce phosphorous loss during the non-growing season by minimizing soil erosion processes and eliminating excess phosphorous; however, most recent studies show that adoption remains relatively low. This report, which uses satellite imagery in corroboration with the Universal Soil Loss Equation, reveals the prevalence of cover crop production and associates soil loss sensitivity at a 30 m resolution from 2013 to 2018. According to this report, areas with higher soil erosion sensitivity are compatible with low-frequency adoption, meaning that these areas are less likely to grow cover crops often. Lake Simcoe is prone to total phosphorus loading, with cover crops promoting farm-scale benefits as a result of soil erosion.

Temporal and Spatial Variation and Driving Forces of Soil Erosion on the Loess Plateau before and after the Implementation of the Grain-for-Green Project: A Case Study in the Yanhe River Basin, China

The Grain-for-Green Project has been in the Loess Plateau area of northern Loess, but there have been no quantitative studies of the effect of ecological engineering on soil erosion in the Loess Plateau region. We used ArcGIS software, the Revised Universal Soil Loss Equation model, and the Geographic Detector system to investigate soil erosion and driving forces in the spatial environment of soil erosion and driving forces before and after the establishment of the Grain-for-Green Initiative in Yanhe River Basin, a typical area on the Loess Plateau. The main determining factor of the two-factor interaction on soil erosion spatial differentiation changed from the slope factor and other variables to the vegetation coverage and other variables.
