River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

open access: yesReviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Quantifying Deep Groundwater Contributions to Streamflow With Inequality‐Constrained EEMMA From Sparse Isotope Series in Alpine Permafrost Basins

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract In alpine permafrost basins, dry‐season runoff largely depends on subpermafrost groundwater (BPG, deep groundwater), yet cryohydrogeological conditions are complicated by time‐varying hydrothermal regimes. Combined with the storage and regulation effects of permafrost on runoff, hydrograph‐based estimates of the fractional contribution of BPG ...

Toward Peace With Nature: Protected Areas Effectively Mitigate Wild Ungulate‐Livestock Competition Despite Spatial Mismatch on the Qinghai‐Tibet Plateau

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Competition for forage between wild ungulates and grazing livestock poses a critical challenge for sustaining grassland ecosystems and pastoral livelihoods. Protected areas (PAs) may mitigate competition, but quantitative multi‐species assessments that simultaneously integrate habitat overlap, forage availability, and conservation ...

Impacts of Transient Critical Zone Evolution on Landslide Susceptibility and Hazard Across the Utuado Batholith, Puerto Rico

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Landscapes in humid climates often experience rapid chemical and mechanical weathering that can change groundwater fluxes, drainage pathways, and frictional strength via alterations in subsurface mineral composition and matrix porosity. These changes to hillslope critical zone structure and strength should control landslide susceptibility ...

Global Estimate of Reservoir Hydropower Storage Potential Based on SWOT Observations

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Hydropower is pivotal to the global transition toward carbon‐neutral energy, yet its actual potential remains constrained by uncertainties. Global assessments have traditionally relied on static metrics, such as dam height, which obscure the dynamic water fluctuations that govern operational reliability.
