Forecasting the Impact of Climatic Factors on Sand Dune Mobility in the Salt Lake Basin using Sensitivity Analysis. [PDF]

Desert
Due to its location in in the arid and semi-arid region of central Iran, The Salt Lake basin is constantly affected by erosive winds leading to the transportation and deposition of sediments.

Carbon–Phosphorus Limitation Is Associated With Shifts in Microbial Life‐History Strategies Across Vegetation Restoration Modes in Alpine Sandy Land on the Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Alpine sandy land on the Tibetan Plateau is fragile, with poorly developed soils, low nutrient availability, and weak biological resilience. Vegetation restoration is widely used to improve soil functioning, yet how microbial nutrient limitation and life‐history strategies vary among restoration modes remains unclear.

Synergistic Regulation of Soil Function and Wind Erosion Resistance by Sand Barriers, Vegetation, and Artificial Biological Crust in the Tengger Desert

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian desertification poses a critical threat to ecosystem stability in arid regions worldwide. Although the combination of sand barriers and vegetation has been widely applied for sand fixation, its long‐term effectiveness is constrained by barrier degradation, slow natural development of biological soil crusts (BSCs), and the resulting ...

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Primary vegetation development on the sand spit of Shallow Inlet, Wilsons Promontory, southern Victoria [PDF]

, 2013
The sand spit that separates Shallow Inlet from Waratah Bay (38º52ʹ S, 146º13ʹ E), near Wilsons Promontory in southern Victoria, has developed since the previous spit was washed out in 1901.

A Land Potential‐Based Framework for Wind Erosion and Sand and Dust Storm Source Mitigation

Land Degradation &Development, EarlyView.
ABSTRACT Wind erosion and sand and dust storms are a global challenge. While many management practices to mitigate sources of wind erosion and sand and dust storms have been documented, existing guidance largely emphasizes what practices are available, with limited information on where and under what ecological conditions they should be applied.

Effects of organic amendments on sand dune fixation

International Journal of Recycling of Organic Waste in Agriculture
Background Poor physical and chemical properties of sand dune soil are the main constrains in afforestation of sand dune in desertified area. The aim of this study is to improve the physical and chemical properties of dune soil in Elrawakeeb Dry Land ...

Differences in Dust Emission and Near‐Surface Transport Patterns Among Three Surface Substrate Types

Land Degradation &Development, EarlyView.
ABSTRACT Soil wind erosion is a major driver of atmospheric dust emissions and land degradation. Many studies have examined dust release from different substrates, but differences in methods and units still limit quantitative understanding of how surface conditions and wind jointly control dust emission and near‐surface transport. A closed‐circuit wind
