Remote sensing image segmentation of gully erosion in a typical black soil area in Northeast China based on improved DeepLabV3+ model

Ecological Informatics
Gully erosion, a cause of soil degradation and reduced crop yields is widespread in the diffuse river and hillock regions of Northeast China. The surface conditions in gully erosion areas are complex, and manual extraction methods are inefficient ...

Integrating Machine Learning and StoDyM for Check Dam Site Selection on the Loess Plateau, China

Land Degradation &Development, EarlyView.
ABSTRACT Severe soil erosion in the Loess Plateau has led to significant land degradation, threatening agricultural productivity and ecosystem stability. Check dams, as a critical soil–water conservation measure, have proven effective in mitigating sediment loss and reclaiming farmland.

Impact of Road Network Development on the Spatiotemporal Soil Erosion in the Three‐River Source Region

Land Degradation &Development, EarlyView.
ABSTRACT As a vital water conservation region in China, the Three River Source Region (TRSR) plays a critical role in safeguarding regional ecological security and ensuring the sustainable utilization of water resources. In this study, the Revised Universal Soil Loss Equation (RUSLE) was employed to quantify soil erosion in the study area across three ...

Spatio-Temporal Characteristics of the Morphological Development of Gully Erosion on the Chinese Loess Plateau

Remote Sensing
Morphology is an important characteristic of the hydraulic and gravitational processes driving gully erosion. In this study, field scouring experiments were conducted on five experimental plots using terrestrial laser scanning to study gully erosion ...

What is the best technique to estimate topographic thresholds of gully erosion? Insights from a case study on the permanent gullies of Rarh plain, India

, 2021
The Rarh plain in the Lower Ganga Basin in India, best known for its lateritic landscape and gullied tracts, faces grave problems brought about by all types of soil erosion, of which gully erosion is the most conspicuous.

Topic: Smallholder Farmers' Adaptation Practices to the Effects of Land Degradation on Livelihoods in Semi‐Arid Ghana

Land Degradation &Development, EarlyView.
ABSTRACT Although several environmental challenges exist globally, land degradation is the greatest threat and risk factor wedging human livelihoods. Despite widespread awareness of climate change, little empirical evidence exists on land degradation and its impacts on livelihoods in semi‐arid agroecological systems.

A hybrid in situ and on-screen survey to monitor gully erosion across the European Union

Scientific Data
After the successful mapping of gully erosion channels in the 2018 Eurostat Land Use/Cover Area Frame (topsoil) statistical survey (LUCAS, n = 24,759 locations), the methodology was further expanded across the full LUCAS 2022 survey (n = 399,591 ...

Establishing Monthly Benchmarks for Erosion Control and Vegetation Restoration Targets Across the Loess Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Establishing scientifically grounded soil erosion control targets and feasible vegetation restoration strategies is crucial for high quality development of the Chinese Loess Plateau which is severely affected by soil erosion. Currently, the commonly used tolerable soil loss (TSL) is inadequate for addressing the spatial heterogeneity in ...

Responses of runoff and sediment yield to rainfall regimes in a typical slope–gully system on the Loess Plateau: A 24-year field monitoring study

Geoderma
Slope–gully system serves as a critical erosion unit on the Loess Plateau, and its slope and gully refer to summit and ridge, and steeper gully wall, respectively.
