Global population impacts of land grabbing for large-scale agriculture

This paper estimates that large-scale land acquisitions for agriculture have affected a minimum of 177 to 250 million people globally since 2000, often encroaching on Indigenous and local communities' lands in densely populated areas, thereby challenging the notion that such deals target underutilized land.

Exposure, perception and institutional response at the abattoir community interface: quantifying the environmental-justice gap in complaint driven regulation in Bo and Kenema Cities, Sierra Leone

This study of Sierra Leone's abattoir communities reveals that while residents accurately perceive environmental risks, the current complaint-driven regulatory system disproportionately serves the most vocal and exposed households, systematically excluding unaware and less vocal residents despite widespread facility deficiencies.

Non-Linear Parameter Uncertainty Propagation Across Multi-Frequency Flood Hydrographs in a Responsive Mountain Catchment

This study demonstrates that parameter uncertainty in mountain catchment flood modeling propagates non-linearly across storm intensities, where high-magnitude events shift hydrograph peaks and significantly widen absolute discharge uncertainty despite downstream attenuation, underscoring the necessity of stochastic frameworks for robust flood risk assessment.

Petrography and Palynology of Carbonate Concretions From the Lower Cretaceous Romualdo Formation Lagerstätte, Brazi

This study integrates petrographic and palynological analyses of carbonate concretions from Brazil's Romualdo Formation to demonstrate their syngenetic-to-early-diagenetic formation via fluorapatite, carbonate, and pyrite precipitation, while revealing a palynological assemblage indicative of a warm, arid-to-semi-arid coastal–estuarine environment with strong marine influence during the late Early Cretaceous.

Hurricane Impacts on Gulf Coast Coastal Ecosystems: A Systematic Review of Socio- Ecological Vulnerability and Policy Responses in the Northern Gulf of Mexico

This systematic review of 23 studies on the northern Gulf of Mexico demonstrates that hurricane impacts on coastal ecosystems are inextricably linked to socio-economic vulnerabilities, necessitating adaptation strategies that integrate ecosystem protection with equitable policy responses.

Novel Use of Local Climate Zones: Urban Form-based Method for Carbon Sink Assessment using Convolutional Neural Network

This study proposes a novel urban form-based method for estimating city carbon sinks by integrating Local Climate Zone (LCZ) maps with a Convolutional Neural Network (CNN) model, demonstrating that lower-intensity built environments (LCZ 5, 6, and 9) offer greater carbon sequestration potential while achieving high estimation accuracy despite sensitivity to LCZ map precision.
