Mercury Transport in a Soil-bentonite Backfill for Slurry Trench Cutoff Walls

This study demonstrates that soil-bentonite backfill mixtures, specifically those using Colombian bentonite to achieve low hydraulic conductivity, effectively retain over 94% of mercury from contaminated solutions through significant sorption, making them a viable barrier material for mitigating mercury transport in artisanal gold mining tailings ponds.

Forest-to-Tourism Conversion in Indonesia: A Systematic Literature Review of Ecological Outcomes, Livelihood Substitution, and Governance Failures (2010–2026)

This systematic literature review of 42 studies (2010–2026) reveals that while forest-to-tourism conversion in Indonesia is predominantly framed as a win-win strategy, empirical evidence is skewed by publication bias and geographic gaps, exposing critical governance failures and livelihood substitution gaps that undermine ecological integrity and community well-being.

Spatial constraints and drivers of pastoral adaptation to climate change in West African rangelands: A multivariate probit analysis

This study analyzes spatial constraints and socio-economic drivers of pastoral adaptation in Burkina Faso using a multivariate probit model, revealing that climate-induced resource scarcity and conflicts compel herders to adopt integrated, complementary strategies influenced by household characteristics, thereby underscoring the need for policies that secure transhumance corridors and enhance resilience.

Urban Heat Island expansion in Khulna City of Bangladesh (1995-2025): Linking LULC change and Land Surface Temperature to heat-related health and economic risks

This study analyzes the spatiotemporal expansion of the Urban Heat Island in Khulna City, Bangladesh (1995–2025), revealing that rapid urbanization and vegetation loss have significantly increased land surface temperatures, thereby exacerbating heat-related health risks for vulnerable populations and causing substantial socio-economic disruptions.

Assessment of Excess Lifetime Cancer Risk from Environmental Gamma Radiation in Ulaanbaatar City, Mongolia

This study evaluated environmental gamma radiation in Ulaanbaatar City using 2025 soil samples and Monte Carlo simulations, finding that the estimated excess lifetime cancer risk (0.261 ± 0.035)×10⁻³ is below international safety limits, thereby indicating a relatively low radiological risk for residents.

Three-Dimensional P- and S-Wave Local Earthquake Tomography of the Eastern Alborz, Northern Iran

This study utilizes 3D P- and S-wave local earthquake tomography to reveal pronounced crustal heterogeneity and concealed fault structures in the eastern Alborz, demonstrating that active deformation is localized within mechanically heterogeneous domains and providing a refined geophysical framework for seismic hazard assessment in the Arabia–Eurasia collision zone.

Environmental Suitability Reveals Under-Surveyed Refugia for Endemic Damselflies in an Afromontane Region

By integrating ensemble species distribution modeling with historical sampling data, this study identifies significant under-surveyed high-elevation refugia for threatened endemic damselflies in Zimbabwe's Eastern Highlands, suggesting that their apparent rarity often reflects sampling gaps rather than true absence and providing a framework to prioritize future conservation surveys.
