Effect of Stand Density on Soil Microbial Carbon and Nitrogen Use Efficiency in Robinia pseudoacacia Plantations in the Loess Hilly‐Gully Region, China

Land Degradation &Development, EarlyView.
ABSTRACT Soil microbial carbon (CUE) and nitrogen (NUE) use efficiency are critical for soil carbon (C) sequestration and nitrogen (N) availability. However, how microbial CUE and NUE respond to stand density is unclear. Furthermore, it remains unclear whether the response of microbial CUE and NUE to stand density could be mediated by soil depth.

Modeling of driving factors and headcut rates of ephemeral gullies in the loess plateau of China using high-resolution remote sensing images

International Journal of Digital Earth
Ephemeral gully headcut erosion contributes significantly to global land degradation and increased sediment yields, but the underlying driving factors and prediction models remain poorly understood.

Post‐Mining Conservation Measures for Erosion Control: A Global Assessment of Their Effectiveness on Runoff and Soil Erosion Reduction

Land Degradation &Development, EarlyView.
ABSTRACT Mining activities severely disturb land surfaces and hydrological processes, intensifying hillslope erosion and soil loss. To evaluate the effectiveness of post‐mining restoration measures and identify the factors regulating their performance, we compiled a global dataset of runoff and soil erosion yield from 58 studies spanning multiple mine ...

Multi-parametric GIS analysis to assess gully erosion susceptibility: a test in southern Sicily, Italy [PDF]

, 2010
: A GIS-analysis was carried out in a test basin of southern Sicily, the Magazzolo River basin, in order to assess susceptibility conditions to gully erosion phenomena. The linear density of ephemeral and permanent gullies computed within each class of

A Generic Approach to Creating a National Soil Security Strategy

Sustainable Development, EarlyView.
ABSTRACT Soil is a living and non‐renewable resource that underpins our very existence. It produces our food, filters our water, stores vast amounts of carbon, cycles essential nutrients, and sustains the rich tapestry of biodiversity on which our planet depends.

Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

Sustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.

Terrain Synthesis and Authoring based on Iso‐Contours

Computer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.
