Who Generates the Carbon Emissions Embedded in Tourism Demand? Uncovering Hub Sectors and Strategic Roles in China’s Intersectoral Emission Network

This study integrates environmental input-output analysis with complex network theory to reveal that China's tourism-driven carbon emission network has evolved into a scale-free structure dominated by a few key hub sectors, suggesting that effective decarbonization policies must target these specific "receiver" and "carrier" sectors based on their distinct structural roles.

Research on Pollutant Identification and Water Quality Change Patterns in Coal Mining Subsidence Areas with High Diving Level in Eastern China

This study analyzes three years of water quality data from 102 subsidence areas in Huainan's high water-table coal mining region to identify total phosphorus and nitrogen as primary pollutants, revealing seasonal eutrophication patterns driven by non-point sources in the flood season and point sources in the dry season, while utilizing isotope and statistical modeling to trace pollutant origins and inform differentiated management strategies.

Assessment of Spatio-temporal urban heat island dynamics in Bolgatanga municipality, Ghana using multitemporal Landsat imagery

This study utilizes multi-temporal Landsat imagery and meteorological data to demonstrate that the Urban Heat Island effect in Bolgatanga, Ghana, intensified significantly between 2007 and 2021, with land surface temperatures rising from 33.66°C to 42.46°C primarily due to urban expansion and vegetation loss, thereby highlighting the need for climate-resilient urban planning in sub-Saharan cities.

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.
