Summary: This study aimed to explore the sensitivity of two Mediterranean soils to water and wind erosion. The results showed that the sensitivity of soil to erosion forces is opposite, indicating that soil erodibility depends on the erosive force applied. Furthermore, different soil properties affect the size and stability of soil aggregates, which control the rate of soil loss to erosion.

Summary: This study aimed to identify and prioritize the wind-erosion-prone dried-up beds of Lake Urmia, Iran, using field sampling data and in-vitro measurement. The results showed that the wind erosion susceptibility varied in the dried-up beds, with the highest susceptibility observed in the southeastern and northwestern parts of Lake Urmia. The study highlights the importance of taking technical and managerial measures to stabilize dust-salt hotspots in the dried-up beds of Lake Urmia.

Summary: Drylands in China face the dual threat of water erosion and wind erosion. This study explores the spatial variation of soil erodibility in China's drylands and examines the effects of aridity, vegetation, and soil properties on soil erodibility. The results show that aridity has a negative effect on water erosion, while soil properties have a more pronounced effect on soil erodibility than vegetation. This study provides valuable information for implementing vegetation restoration and soil conservation measures in drylands.

Summary: This research examines the relationships between organic soil properties and soil height variation, as well as analyzes the erodibility of cultivated organic soil. The study finds that certain soil properties, such as bulk density and organic matter content, significantly affect soil height variation and wind erodibility. These findings are important for the sustainable management of organic soils and can be used in developing a wind erosion risk model.

Summary: Land use type can impact soil properties and plant community characteristics, which in turn affect soil erodibility. The conversion from natural forestland to cropland leads to serious soil erosion due to irrational land use. Few studies have assessed the potential effect of land use type on soil erodibility at small watershed scale. This study quantified the effects of six typical land use types on soil erodibility in a small watershed in northeast China. The results showed significant variations in soil properties and erosion indices among different land use types.

Summary: Urbanization has both negative and positive impacts on soil quality, with an increase in soil salinity, heavy metals, and erodibility, while also increasing organic matter, nitrogen, phosphorus, and cation exchange capacity. The study found that urban soils exhibited a decrease in SQI scenarios compared to control soils, indicating worsening soil quality in urban areas. The highest values of soil quality indicators were observed in Fluvisols, suggesting a combined influence of soil type and agricultural management practices.

Summary: Soil erodibility (K-Factor) is an important parameter for estimating rainfall erosion through mathematical models. Analyzing soil erodibility at different depths can identify its susceptibility to erosion. However, the lack of a comprehensive field database is a major limitation in applying this method.

Summary: Windblown and water-induced erosion have a significant impact on soil loss globally, especially in drylands. This paper presents a laboratory investigation on the use of cyanobacteria to improve erosion resistance in sandy soils. The experimental results show that the bio-crust developed on the soil surface can greatly enhance the soil's resistance to erosion. The microstructure of the bio-crust, influenced by the cyanobacterium strain and soil properties, plays a crucial role in improving erosion resistance.

Summary: Wildfires increase stemflow velocity by 30-40%. Stemflow velocity is positively related to stemflow rate and tends to increase with stem height. Pine bark fissure depth and width are negatively related to stemflow velocity. Wildfires reduce soil internal friction angle and cohesion by up to 32% and 62% respectively. Enhanced stemflow velocity can cause soil erosion around the base of the trunk.

Summary: This study aims to use alkali-activated slag to mitigate wind erosion of soil. Wind tunnel tests were conducted on soil samples treated with different percentages of slag at various wind speeds and under sand bombardment conditions. The results showed that the treated samples had significantly lower erodibility compared to the untreated samples, with reductions ranging from 98.5% to 99.6% depending on the percentage of slag used. The formed crusts in the treated samples exhibited a much higher strength than the untreated sample, providing substantial protection against wind erosion.

Summary: This study evaluated the impact of different land use types on soil quality in the Konya-Karapinar region and established a minimum dataset for the soil quality index (SQI). The results showed that there were significant improvements in soil quality compared to the wind erosion affected area, but the improvements were more limited in grazing land and forested land. It is recommended to allocate more land for horticulture in erosion protection areas.

Summary: Wind erosion is a global environmental problem, with a focus on local scales in current modeling efforts. The study found that Africa and Asia are responsible for the majority of global soil loss due to wind erosion. Global wind erosion showed a decreasing trend during the study period, with fluctuations in soil loss rates correlated with weather factors and vegetation coverage.

Vegetation NPP showed a moderately positive correlation with temperature, accumulated temperature (>10 degrees C), and sunshine, while having an overall negative relationship with precipitation. The dominant factors and interactive dominant factors changed in different sub-regions over the study period.

Summary: Previous studies have used satellite image parameters to construct monitoring models for salinisation, with a limited number combining these models with SENTINEL-2B MSI images. The red edge index from SENTINEL-2B MSI images provides detailed vegetation information for monitoring salinised land ecosystems. By introducing seven parameters and constructing two feature space models based on the SENTINEL-2B MSI images, a novel salinisation monitoring index for the Yellow River Delta was developed. The results showed high applicability of the monitoring model, with the red edge index playing a crucial role in indicating soil salinisation and highlighting the severity of salinisation in the eastern and northeastern regions, providing a new technical approach for regional salinisation prevention and treatment.

Summary: This study analyzed the evolution of soil salinization in the Yellow River Delta from 1984 to 2022 using a three-dimensional feature space method. The results showed that the salinization intensity in the delta increased from the inland southwest to the coastal northeast. The implementation of salinization control measures has exacerbated salinization, particularly in the northeast. However, some cultivated land in the southwest has shown improvement in salinization.

Summary: This study used the PLUS model to predict land use change from 2030 to 2060 under multiple scenarios, and supplemented vegetation type data using the CA model to obtain land cover-vegetation datasets. Combining with carbon density table of vegetation type, future land use carbon storage in Beijing-Tianjin-Hebei region during 2030-2060 under multiple scenarios was analyzed. The main conclusions are as follows: (1) The spatial distribution of carbon storage in Beijing-Tianjin-Hebei region exhibited a pattern of 'high in northeast-southwest and low in southeast-northwest'; (2) Carbon storage in Beijing-Tianjin-Hebei region showed a decreasing trend during 1990-2020; (3) During 2030-2060, carbon storage in Beijing-Tianjin-Hebei region showed a continuous decreasing trend without policy intervention, while it showed an increasing trend under the ecological protection and farmland protection scenarios; (4) Significant differences in spatial distribution of carbon storage were observed under different development scenarios.

Summary: This study evaluates the coupling coordination degree (CCD) between regional haze disaster risk index (HRI) and urbanization development index level (UDI) in China using a combination of remote sensing and statistical data. The results show that haze pollution level has fluctuated downward, UDI has shown a gradual upward trend, and CCD has improved from low to moderate coordination. The study highlights the importance of considering both HRI and UDI in achieving regional sustainable development goals.
