Nature-Based Solutions (NbS) for the Ecological Reclamation of Abandoned Volcanic Tuff Quarries and Flood Risk Mitigation: The Case of Artik, Armenia

This study demonstrates that implementing an integrated Nature-Based Solutions framework involving terracing, soil amelioration, and reforestation successfully restored a 40-hectare abandoned volcanic tuff quarry in Artik, Armenia, by significantly improving soil health, ensuring high sapling survival, and completely eliminating coarse sediment transport to mitigate flood risks.

Reducing acid mine drainage potential in sulfide-rich tailings through selective sulfide removal: A case study from a polymetallic mine deposit in northeastern Türkiye

This study demonstrates that selective pyrite flotation effectively reduces the acid mine drainage potential of sulfide-rich tailings from a polymetallic mine in northeastern Türkiye by significantly lowering total sulfur content and shifting geochemical indicators from acid-generating to acid-neutralizing conditions.

Long-term vegetation–thermal coupling and environmental resilience in a mining-affected tropical forest landscape

This study analyzes 30 years of remote sensing data in India's Saranda Forest Division to reveal that while vegetation health and land surface temperature exhibit a strong, persistent negative coupling, their relationship with rainfall is weak and inconsistent, highlighting the complex environmental resilience of this mining-affected tropical landscape.

Integrated Analysis of Gutenberg Richter b-value and Apparent Stress Reveals Spatial Heterogeneity of Seismotectonic Conditions in the Gulf of California Rift System

This study integrates Gutenberg-Richter b-values and apparent stress analysis of USGS earthquake data to reveal distinct spatial heterogeneities in the seismotectonic conditions of the Gulf of California Rift System, demonstrating that combining these complementary parameters enhances seismic hazard assessment in active continental rifts.

Five-Year Analysis (2019-2023) of Anatoxin-a (ATX-a) concentrations in Lake Anna, Virginia, USA: Implications for Future Freshwater Cyanotoxin Monitoring

This five-year study (2019–2023) of Lake Anna, Virginia, documents the first multi-year record of anatoxin-a in a US lake, revealing that 14% of samples exceeded drinking water thresholds and that toxin concentrations are strongly driven by rising water temperatures and cyanobacterial abundance, thereby underscoring the urgent need for expanded monitoring and community engagement.

From ecological interaction vulnerability to multiple breadbasket failure: a cross-domain material-transmission framework

This paper proposes a cross-domain material-transmission framework that synthesizes fragmented literature to demonstrate how antecedent ecological and crop response diversity moderates the risk of multiple breadbasket failures and subsequent food-system shocks through distinct transition mechanisms like domino effects and hidden feedbacks.

Watershed urbanization drives nonlinear water-quality responses across mangrove-associated coastal systems

This study analyzes 31 years of monitoring data from four subtropical Brazilian watersheds to demonstrate that urbanization drives nonlinear declines in mangrove-associated water quality, with a critical threshold around 10% urban cover, highlighting the necessity of integrated watershed management to protect coastal ecosystems.

Analysis and Predictive Modelling of Oceanic Variables in the Atlantic Ocean Using Multivariate Statistical Methods

This study employs multivariate regression analysis on Atlantic Ocean observations to demonstrate that a three-predictor model yields optimal results, revealing an asymmetric predictive structure where eastward current velocity serves as the central driver for salinity and temperature variability while also being the most coherent variable explained by the thermohaline state.

Rethinking Ecosystems, Climate Change and Insecurity Through Indigenous Knowledge Systems

This paper argues that integrating Nigeria's Indigenous Knowledge Systems with contemporary scientific and policy frameworks is essential for effectively addressing climate change, ecosystem degradation, and human insecurity, as these traditional practices offer proven, sustainable mechanisms for environmental conservation and community resilience that have been historically marginalized.
