Summary: This study explores the relationship between fire regime and potential biophysical controls in central Portugal, finding that land use, seasonal rainfall, and temperature are major factors influencing the variability of fire regime properties. The study highlights the importance of shrubland and spontaneous herbaceous vegetation, as well as spring rainfall, in influencing the cumulative percentage of area burned and the Gini concentration index of burned area.

Summary: The Arctic and Boreal Region (ABR) undergoes extensive land cover change (LCC) due to factors such as wildfire, permafrost thaw, and shrubification. These LCCs alter important biophysical variables including land surface temperature (LST), albedo, and evapotranspiration (ET), which have a significant impact on the warming trend over the ABR. The sensitivity of these variables to different types of LCC in heterogeneous systems like ABR remains uncertain.

Summary: This study developed an R-eco model driven by long-term global-scale Earth observations and analyzed the spatiotemporal dynamics of R-eco from 1982 to 2015. The results revealed a significant increase in global R-eco during recent decades, but a slower growth rate during 1998-2015, which partially explains the reduced growth rates of atmospheric CO2 during this period.

Summary: The seasonal greening of Northern Hemisphere ecosystems, due to extended growing periods and enhanced photosynthetic activity, modifies near-surface warming by perturbing land-atmosphere energy exchanges. Summer greening effectively dampens NH warming by enhancing evapotranspiration, while spring and autumn greening results in minor temperature changes.

Summary: This study examines the biophysical effects of land cover changes on land surface temperature in the Sichuan Basin and surrounding regions in China by using satellite remote sensing data and space-time analysis. The results show that land cover changes have a significant impact on surface temperature, with a seasonal pattern of warming in summer and autumn and weak cooling in winter. The findings underscore the importance of biophysical effects in local climate change.

Summary: This study conducted a global meta-analysis on 487 sites to investigate the impact of different types of land use and land cover change (LULCC) on soil carbon (C) and nitrogen (N) dynamics in wetlands. The results showed that conversion of wetlands to various LULCC types decreased soil C and N concentrations and stocks significantly. The loss of wetland soil C due to LULCC could lead to potential CO2 emissions, highlighting the importance of sustainable land management for wetland conservation in mitigating climate change.

Summary: This study systematically analyzed the trend of difference between satellite-based land surface temperature and station-based air temperature from 2003 to 2022. The results showed that during daytime of summer, the satellite-based temperature exhibited slower warming rate compared to the station-based temperature, which was attributed to recent Earth greening. However, during summer nighttime and winter daytime and nighttime, the satellite-based temperature showed faster warming rate.

Summary: This study evaluates the potential of multi-source freely available Earth Observation (EO) data for improving the characterization of aquatic land cover globally. Results show that the combination of different data sources can enhance the classification performance of water and vegetation types in aquatic areas. However, single-sensor data has limitations in discriminating mixed and spectrally similar types.

Summary: This paper discusses the opportunities for using remote sensing technologies to address global challenges related to the artisanal and small-scale gold mining (ASGM) sector. It explores the various uses of remote sensing in detecting and monitoring ASGM activities around the world through a systematic literature review. The study highlights the importance of freely-available data in understanding ASGM activities and discusses the applications and opportunities in assessing the geospatial and temporal characteristics of ASGM and its environmental impacts. Additionally, case studies in the Democratic Republic of Congo and Colombia demonstrate the identification and quantification of the effects of ASGM activities on land degradation and water turbidity, using cloud computing with the Open Data Cube and disseminating results through the MapX platform. This research facilitates policy development, implementation, and evaluation in the ASGM context.

Summary: Armed conflicts have negative impacts on the environment, particularly land systems. The current understanding of the relationship between Land Use/Land Cover (LULC) and armed conflict fails to fully grasp the complexity of their dynamics, which could threaten food security and sustainable land/water resources management in conflict zones. A new methodology that combines remote sensing products, machine learning techniques, and quasi-experimental statistical analysis has been developed to better understand LULC changes in the Orontes River Basin (ORB) between 2004 and 2022, offering insights into the impact of conflict and refugee settlements on land use patterns.

Summary: Research on the nitrogen cycle has shown that the production of reactive nitrogen globally exceeds the natural ecosystem's capacity for removal through denitrification, leading to negative impacts on the environment and human health. Wetland ecosystems play a significant role in denitrification, but uncertainties remain in quantifying the denitrification capacity of natural wetlands globally.

Summary: The study utilized Google Earth Engine to construct historical land-cover maps for Australia and classified land-cover using a random forest model, finding significant decreases in cropland and forests over 30 years, while built-up areas showed a noticeable increase. Additionally, classification uncertainty was lower in more homogeneous landscapes.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
