Summary: The riverfront along the Yangtze River in Jiangsu province is of great importance for economic and social development and eco-environmental protection. This study identified ecological problems and risks at different spatial scales and constructed an ecological risk assessment index system. The results showed the presence of hot spots and cluster zones of ecological risk. Based on the analysis, suitable risk management and resource protection measures are proposed.

Summary: The study investigated the occurrence, spatial distribution, and temporal trend of PFASs in 21 water sources along the Jiangsu section of the Yangtze River, assessing their health risks to human and ecological risks. It found considerable risks posed by PFASs, especially PFOS, PFOA, and PFBS, in some hotspot areas, highlighting the need for monitoring and standards development in China.

Summary: Understanding rural sustainability requires scrutiny of the relationship between rural transition and economic growth, using rural multifunctionality as an analytical lens. The study reveals that multifunctional rural transition is influenced by multiple factors and should be understood within a framework incorporating both endogenous and exogenous factors.

Summary: In this study, soil erosion in the complex Chenab river basin was estimated using the Revised Universal Soil Loss Equation (RUSLE) and remote sensing (RS) technology. The results underscore the urgent need for enhanced strategies to control and mitigate soil erosion in the region due to severe environmental degradation.

Summary: This study assesses the soil erosion rate in various sub-basins of the Alaknanda using the revised universal soil-loss equation (RUSLE) in the GIS framework. The results show that out of the twelve sub-basins, two fall in the high erosional class, nine fall in the moderate erosional class, and one basin in the low erosional class. This study can assist decision-makers in prioritizing actions for water and soil conservation.

Summary: Erosion of soil by water coupled with human activities is a serious issue of land degradation. This study assessed soil erosion in the lower Sutlej River basin in Punjab, India using the Revised Universal Soil Loss Equation (RUSLE) combined with remote sensing and GIS. The results were used to prioritize watersheds for implementation of land and water conservation measures.

Summary: This study used RUSLE and GIS techniques to estimate soil loss rates and sediment rates caused by rainfall. Remote sensing and soil property information were also used for erosion analysis. The results showed severe soil erosion, with the highest erosion rate in steep areas. A large portion of the basin experienced moderate to high soil loss, with certain catchments prioritized for soil conservation efforts. Sediment deposition was found along the flow direction of the mainstream, with the highest rates in specific regions. The central part of the basin was identified as the most vulnerable to increased erosion rates, indicating progressive sediment deposition.

Summary: This study aimed to comprehensively assess the environmental quality of agricultural soils and the safety of agricultural products. It found that some soil-crop systems were at risk of contamination by heavy metals (HMs), with paddy soils having the highest potential risk followed by maize soils. Integration of soil environmental quality and agricultural product safety provides a novel and reliable approach to evaluate the potential risk of HMs in arable land.

Summary: Geohazard mapping using remote sensing and GIS is effective in estimating and mapping soil erosion in Nam UN Basin. The study shows that 33.40% of the region is highly prone to severe soil erosion. Decision-makers use soil erosion prognosis analysis and the Analytical Hierarchy Process (AHP) to identify key soil erosion prone locations.

Summary: Soil is essential for food production and plays a vital role as a habitat. Preventing soil erosion, particularly caused by water, is crucial. This study fills a research gap in modeling soil loss in Northern and Eastern Europe and assesses the impact of climate change on soil erosion rates in Poland. The results show projected increases in soil erosion rates in the future, highlighting the importance of soil conservation policies.

Summary: This study investigated the diffusive flux of methane (CH4) and its stable carbon isotope signature (delta C-13-CH4) in the Yangtze River. The results showed that the diffusive CH4 flux was 27.9 +/- 11.4 mu mol/m(2)/d and 36.5 +/- 24.4 mu mol/m(2)/d in wet season and dry season, respectively. The stable carbon isotope signature indicated that the river-estuary continuum is dominated by hydrogenotrophic methanogens.

Summary: The study introduces an improved method for calculating slope length in the DWESL model, which utilizes the ITF method combining topographical features slope line, contour curvature and cutoff factors. The extracted slope length using this method had the smallest error in verification of mathematical surfaces and its spatial distribution was more consistent with the terrain surface structure compared to the conventional flow direction algorithms in the original DWESL model.

Summary: This study reveals the important roles of seed endophytes in controlling Cd accumulation in rice. Significant differences in Cd content were observed in soils and rice seeds. Bacteria such as Stenotrophomonas and Enterobacteriaceae, as well as altitude and pH, were found to reduce Cd uptake in rice, while Cytophagaceae, latitude, and mean annual air pressure had the opposite effect. In pot experiments, inoculating Stenotrophomonas T4 and Enterobacter R1 significantly decreased Cd content in shoots compared to controls. The study highlights the threat of widespread Cd pollution to food security.

Summary: The study presented the first in-situ expression patterns of comammox Nitrospira in the Yangtze River, revealing their importance in the nitrogen cycle, particularly in the conversion between ammonia and nitrite. The two comammox clades showed distinct functions in nitrification, with clade A dominantly involved in ammonia oxidation and clade B contributing more to nitrite oxidation.
