From Land-Cover Transitions to Water Conflict: A Systematic Review of Hydrological Variability, Resource Competition and Governance Responses in Intermittent River Catchments

This systematic review synthesizes evidence from 104 studies to demonstrate that water-related conflict in intermittent river catchments is driven not by physical scarcity alone, but by coupled socio-hydrological processes where land-cover transitions and hydrological variability intensify resource competition, necessitating governance responses that address both ecological and institutional dimensions.

Integrated Remote Sensing Techniques and Field Investigation for the Identification of Potential Sources for Alluvial Gold Deposits in the Kapoeta Area, South Sudan

This study demonstrates that an integrated approach combining Landsat and SRTM remote sensing techniques with field investigations effectively maps lithological units, structural features, and alteration zones to identify potential sources for alluvial gold deposits within the Kapoeta area of South Sudan.

Near-term impacts of the 2024 mass coral bleaching event on benthic and fish communities in Okinawa Island, southern Japan

The 2024 unprecedented mass bleaching event in Okinawa Island caused severe, depth-dependent coral mortality and benthic shifts dominated by *Acropora* loss and algal proliferation, while fish community responses remained largely stable in the short term with declines limited to obligate corallivores.

Climate refugia and tailings-impacted areas: a spatial framework for prioritizing conservation and restoration of native bees in the Rio Doce watershed

This study presents a spatial framework for the Rio Doce watershed demonstrating that climate change will disproportionately reduce suitable habitats for native bees, with future climatically vulnerable areas increasingly overlapping with zones degraded by mining tailings, thereby necessitating targeted conservation and restoration efforts.

Dissolution of Calcareous Mudstone by Indigenous Organic Acids during Thermal Maturation in Qaidam Basin

This study utilizes hydrous pyrolysis experiments to demonstrate that indigenous organic acids generated during thermal maturation in the Qaidam Basin drive a three-stage evolution of calcareous mudstone dissolution, which sequentially establishes a pore network, enhances porosity and permeability, and ultimately reorganizes reservoir space to favor long-term hydrocarbon preservation.

Quantifying the spatiotemporal coupling effects of Shrinkage development policy and climate change on surface runoff

This study develops an integrated framework combining Random Forest, PLUS, and SWAT models to quantify the spatiotemporal coupling effects of shrinkage development policies and climate change on surface runoff, revealing that while ecological conservation policies help mitigate risks, climate change exerts a significantly stronger influence on runoff than land-use regulation alone.

An Extreme-Value Framework for Separating Rainfall Occurrence and Severity: Regime-Dependent Insights for Risk Assessment

This study proposes a diagnostic framework that separates rainfall occurrence and severity to reveal that while event frequency is consistently driven by atmospheric moisture transport across India, exceedance magnitude follows highly localized, regime-dependent patterns, thereby improving the physical interpretability and accuracy of nonstationary risk assessment models.

Nature-dependent lifeways are widely exposed to ecological novelty

This study reveals that over 1.76 billion people globally, particularly those in rural areas dependent on nature, are already exposed to high levels of ecological novelty that diminishes ecosystem services, underscoring the urgent need to integrate these novel socio-ecological conditions into future conservation and sustainability planning.
