Quantifying soil surface erosion
This study quantified soil surface erosion rates using a combination of field measurements and modeling, examining how land use, vegetation cover, and rainfall intensity interact to drive soil loss. The findings provide improved estimates for erosion-driven microplastic transport in agricultural landscapes.
Irrigation Practices and Their Effects on Soil Quality and Soil Characteristics in Arid Lands: A Comprehensive Geomatic Analysis
Researchers examined the long-term effects of irrigation practices on soil quality and soil characteristics in arid regions of Egypt. They analyzed seventy soil samples for various properties including soil organic carbon and nitrogen stocks. The study found that irrigation history significantly influenced soil quality metrics, providing insights important for sustainable land management in water-limited agricultural environments.
Soil Sensitivity to Wind and Water Erosion as Affected by Land Use in Southern Iran
Researchers investigated how long-term land use management affects soil sensitivity to wind and water erosion in calcareous soils of southern Iran, finding that annual cultivated fields showed the greatest erosion vulnerability while orchards and rangelands were more resistant. Soil organic matter content was a key mediating factor across all land use types.
Microplastics in agricultural soils from a semi-arid region and their transport by wind erosion
Researchers found microplastics heterogeneously distributed in agricultural soils from semi-arid Iran, with plastic-mulched and wastewater-irrigated fields both contaminated, and demonstrated that wind erosion can transport microplastics from soil surfaces to new locations.
The Road Map to Classify the Potential Risk of Wind Erosion
This study developed a methodological framework for classifying the risk of wind erosion across different soil and climate conditions. Wind erosion can transport soil particles as well as light microplastic particles across large distances, making erosion risk assessment relevant to understanding microplastic dispersal.
The synchronized dynamic release behavior of microplastics during farmland soil erosion process
Field and laboratory experiments on farmland soil in coastal China showed that roughly half of the microplastics present in agricultural soil can be mobilized and released into water bodies during erosion events. The dynamic release pattern — an initial decrease followed by a sharp increase — is driven by competition between particle adsorption, sedimentation, and resuspension, highlighting that controlling soil erosion is a critical and underappreciated lever for preventing microplastic contamination of rivers and coastal waters.
Understanding the cost of soil erosion: An assessment of the sediment removal costs from the reservoirs of the European Union
Researchers calculated the economic cost of soil erosion in the European Union by estimating how much sediment accumulates in reservoirs and what it costs to remove it, finding the bill likely exceeds 2.3 billion euros per year just from water erosion alone. This matters because understanding these off-site costs can help justify stronger soil conservation policies like the EU's Zero Pollution Action Plan.
A neglected transport of plastic debris to cities from farmland in remote arid regions
Researchers found that wind erosion in semiarid farmland regions transports significant quantities of plastic debris, including microplastics, to distant urban areas, identifying a previously neglected long-range transport pathway in arid environments.
Assessing soil erosion risk in a peri-urban catchment of the Lake Victoria basin
Researchers applied the RUSLE soil erosion model to a peri-urban catchment on Lake Victoria's shore and found average annual erosion of 7 tonnes per hectare, with croplands and steep slopes as the main hotspots, providing the first erosion risk assessment for this under-studied urban African watershed.
Soil erosion and sediment dynamics in the Anthropocene: a review of human impacts during a period of rapid global environmental change
This review examines how human activities have altered soil erosion and sediment transport patterns, particularly since the mid-twentieth century. Researchers found that land use changes, deforestation, and agriculture have dramatically increased erosion rates, while dams and reservoirs have disrupted natural sediment flow to oceans. The study highlights how these changes affect global climate, water security, and the transport of pollutants including microplastics through river systems.
Soil Erosion Estimation Using RUSLE Method
Researchers applied the Revised Universal Soil Loss Equation (RUSLE) method to estimate soil erosion rates in an Indonesian context as part of a broader post-pandemic environmental assessment. The study contributes to understanding land degradation risks that intersect with pollution management and watershed sustainability challenges relevant to Indonesia's development priorities.

Soil erosion is a major drive for nano & micro-plastics to enter riverine systems from cultivated land.
A study quantifying how soil erosion transports nano and microplastics from cultivated land into rivers found that erosion is a major pathway for plastic transfer to aquatic systems, with plastic flux closely linked to soil loss rates and land management practices.
