Diagnosing Water Governance Complexity: A Systemic Causal Analysis of the Qarranqu Basin, Iran

This study employs a qualitative system dynamics framework, integrating Grounded Theory with participatory methods to diagnose the systemic governance failures in Iran's Qarranqu Basin by identifying six core meta-feedback loops and 13 actionable leverage points that link institutional fragmentation and political-economic structures to water crises.

Modeling Soil Volumetric Water Content Based on Climatic Factors in the Tripoli Region (Libya) Using Multiple Linear Regression

This study utilizes multiple linear regression analysis of data from 2001 to 2024 to demonstrate that precipitation is the most significant climatic factor positively influencing soil volumetric water content in Tripoli, Libya, while relative humidity shows a positive correlation and soil temperature exhibits an inverse relationship.

Urban tree cover and meteorological drivers shape spring pollen risk in a data-scarce valley city

This study develops a relative Pollen Risk Index for Lanzhou, China, demonstrating that spring pollen risk in this data-scarce valley city is shaped by the interplay of urban tree cover, phenological progression, and meteorological drivers, thereby providing a framework to guide urban greening strategies and public health warnings.

Temporal Lag Relationship Between Sea Surface Temperature and Fire Hotspot Occurrence in Sumatra During the 2023 Positive Indian Ocean Dipole Event

This study reveals that Eastern Indian Ocean Sea Surface Temperature anomalies during the 2023 positive Indian Ocean Dipole event serve as a statistically significant early-warning indicator for elevated fire risk in Sumatra, exhibiting a delayed response with a peak correlation at a two-month lag due to indirect atmospheric and terrestrial drying processes.

The Impact of International Tourism on Environmental Degradation of the 14 Asia-Pacific Countries

This study analyzes panel data from 14 Asia-Pacific countries (2000–2019) using an ARDL model and causality tests to reveal that international tourism significantly exacerbates environmental degradation by increasing energy consumption and CO2 emissions while accelerating deforestation, thereby highlighting the ineffectiveness of current green tourism policies and the urgent need for renewable energy adoption and eco-friendly initiatives.

Mapping physicochemical properties of soils and reservoir sediments by multi- and hyperspectral satellite data in the Brazilian semiarid region to support the sediment reuse technique

This study demonstrates that combining VNIR-SWIR spectroscopy with multivariate statistical techniques using satellite data (Sentinel-2, PRISMA, and EnMAP) and laboratory spectra effectively maps key physicochemical properties of soils and reservoir sediments in Brazil's semiarid region, thereby supporting sediment reuse strategies for agricultural management.
