This report ranked sub-watersheds in the Upper Bhima Basin based on their need for effective water resource planning and management. Morphometric investigation is required for determining soil erosion-prone areas. According to this report's findings, 30. 00% of the total area is highly vulnerable with sub-watersheds, and soil and water conservation steps must be implemented immediately. This report suggested morphometric analysis using a GIS tool and the novel WSA technique to assist decision-makers in making economically and economically efficient decisions.

Land use change, land use change, land degradation, and soil erosion all increase dramatically, resulting in a loss of fertile soil every year and lead reduction in agricultural production. This report was therefore designed to investigate land use land cover change from 1986 to 2020, to determine mean annual soil erosion rates and pinpoint erosion hotspot areas from 1986 to 2020, and then to assess the effects of land use land cover change on soil loss from 1986 to 2020. The LULC's dynamics were used as an indicator of soil erosion by utilizing a combination of geospatial techniques with the updated universal soil loss equation, which was used as an indicator for measuring soil loss.

In the present research, Revised Universal Soil Loss Equation, a remote sensing and geographic information system, was used to analyze soil erosion in the lower Sutlej River basin of Punjab, India, and prioritize the watersheds for the implementation of land and water conservation projects. The measurements revealed that the average annual soil loss varied from 1. 26 to 25 t ha -1, while total soil loss was estimated to be 2,441,639 tonnes. About 94. 4% and little erosion of the total area, according to the spatial distribution map of soil erosion, while 0. 9 percent experienced significant soil erosion. These results can definitely be used to implement soil conservation policies and management techniques in order to minimize soil erosion in the river basin.

Massive tufa depositions can stretch for up to ten kilometers, resulting in tufa landscapes that have been designated as national parks and World Heritage Sites. In several countries around the world, previous studies have reported that increased soil erosion due to human activities is one of the major causes of fluvial tufa decline. In Jiuzhaigou, we compared the water chemistry and tufa deposition before and after the earthquake to determine the effects of soil erosion on tufa landscapes. Improved soil erosion may also raise the annual tufa deposition rates by increasing the sediment's soil and organic matter. This paper explores the effectiveness of soil erosion on tufa landscapes and determines the need and success of artificial soil erosion control.

gully erosion has been regarded as a key source of sediment supply in an arid and semi-arid environment, washing out the top fertile soil and uncovering lower soil layers. Water erosion is a significant issue in India's late-mattic terrain of Rupai watershed, which is on the eastern plateau fringe of the country, where water erosion is a significant concern. In addition to delineating GEVZ, estimating the average annual soil loss is vital; therefore, the updated universal soil loss equation model is used with geospatial technologies. Around 29% of the study area faces elevated to very high soil erosion risk, while the 68% area faces a low risk of soil erosion. gully depth reveals varying from 0 to 5 meters with V and U shapes, according to the study of gully morphology. The results obtained from this research may help with the planning and management of land use and soil erosion conservation.

Drainage densification has been used to determine the soil erosion by using the Geographic Information System for the Sarbari Khad watershed, which is located in India's less Himalayan region of the Himalayan region. The Sarbari Khad watershed is vulnerable to surface erosion as well as soil degradation, according to a drainage density report that was revealed. The drainage density values have been used in this study to determine the watershed's status in terms of erosion status. These soil erosion differences in the watershed can be used for watershed areas that require soil and water conservation steps to keep the watershed productive.

Using sophisticated monitoring of drainage and morphometric parameters using geospatial methods, a 7 sub-basin catchment in Dudhganga-Shaliganga catchment was analyzed to determine the soil erosion risk, which was determined by detailed measurement of drainage and morphometric parameters using geospatial techniques. With a sub-parl drainage pattern, the stream order up to 6 has been evaluated with a drainage density of 1. 881. DS1, DS2, and DS6 are among the most susceptible to soil erosion susceptibility, according to Ranking. Besides, the sub-basins with higher erosion rick have a higher percentage of lineaments, which helps with rapid water flow and increases the likelihood of landslides by lubrication. Land erosion during heavy rain fall, according to the plainer low lying areas, which is a very difficult problem to solve.

The potential use of slag-fly ash-based geopolymers as stabilizers for soft soil in sulfate erosion areas was investigated in this report to increase environmental security and waste residue recycling. The results reveal that the sulfate resistance of stabilized soil is heavily affected by the stabilizer type. The cement-stabilized soil in the sulfate environment is dramatically affected by erosion age as a result of AFt's expansion stress, while the geopolymer-stabilized soil has excellent sulfate resistance.

In the Midhagdu Watershed in eastern Ethiopia, this research prioritizes planning options and assesses the likelihood of soil erosion. The results of the grid cell-based RUSLE survey revealed that 52. 4 percent of the Midhagdu watershed had poor to moderate soil erosion rates, and that 47. 76 percent had elevated to extremely high soil erosion risk levels. The conclusions of this book suggest an early intervention to properly plan soil erosion risk mitigation by taking into account geographic location and priority classes based on soil erosion risk levels.

The backbone of underpinning global agriculture and food security is healthy soil. Soil erosion is the most significant threat to soil health today, contributing to yield loss, ecosystem degradation, and economic impacts. We provide high-resolution global estimates of soil displacement by water erosion based on the Revised-Universal-Soil-Loss-Equation-based Global Soil Erosion Modelling platform under current and future climate scenarios. GloSEM is the first global modelling platform to factor in regional farming systems, the effects of conservation agriculture conservation, and climate change projections.
