A Review of the Eco-Environmental Impacts of the South-to-North Water Diversion: Implications for Interbasin Water Transfers

Engineering, Journal Year: 2023, Volume and Issue: 30, P. 161 - 169

Published: June 21, 2023

Interbasin water-transfer schemes provide an engineering solution for reconciling the conflict between water demand and availability. In context of climate change, which brings great uncertainties to resource distribution, interbasin transfer plays increasingly important role in global water–food–energy nexus. However, resources simultaneously changes hydrological regime characteristics local bodies, affecting biotic communities accordingly. Compared with high economic technical inputs projects require, environmental ecological implications have been inadequately addressed. This work selects largest project China, South-to-North Water Diversion (SNWD) Project, critically review its eco-environmental impacts on donor recipient basins, as well regions along diversion route. The two operated routes SNWD Project represent typical approaches: Middle Route uses excavated canal, while East connects existent river channels. An overview these is valuable design optimization future megaprojects.

Water quality and habitat drive phytoplankton taxonomic and functional group patterns in the Yangtze River

Ecological Processes, Journal Year: 2024, Volume and Issue: 13(1)

Abstract Background Although phytoplankton are important primary producers in food webs, they relatively less studied large rivers compared to other types of systems. To fill this research gap, we taxonomic and functional composition their relationships with water quality, habitat, climate, land use across 30 river sections the middle lower reaches Yangtze River during 2017–2018. Results Major observed groups were cyanobacteria, bacillariophyta, chlorophyta. Phytoplankton total abundance, biomass, species richness significantly decreased dry season wet season, differing between seasons. differences seasons mainly contributed by Oscillatoria sp., Pseudanabaena Melosira granulata . The dfferences P (including Closterium sp.), Lo Merismopedia Peridinium Ceratium Gymnodinium J Pediastrum Tetraedron Crucigenia Scenedesmus Coelastrum sp.). variance partitioning showed that quality (NO 3 -N, suspended solids, turbidity) habitat (water flow, bank channel conditions) critical factors shaping patterns, followed climate use. Conclusions indicated there was significant seasonal variation River, primarily driving patterns. Our study contributes understanding natural anthropogenic drive successional processes River. These findings have implications for environmental management as well towards ecological restoration rivers.

Biotic Integrity Assessment of Multi-Trophic Cascade in Former Chinese Sturgeon Spawning Grounds Using Environmental DNA Metabarcoding Technology

Water, Journal Year: 2025, Volume and Issue: 17(4), P. 554 - 554

Published: Feb. 14, 2025

In comparison with traditional species identification techniques, environmental DNA (eDNA) metabarcoding technology markedly enhances the resolution and precision of classification, while simultaneously facilitating efficiency accuracy data collection. However, majority extant methods for assessing biological integrity concentrate on monitoring at a single trophic level, there is paucity systematic studies that consider multi-trophic level biomes in an integrated manner. Accordingly, aim this study was to conduct comprehensive assessment biotic communities downstream section Gezhou Dam Yangtze River mainstem, which formerly constituted Chinese sturgeon spawning grounds, utilizing eDNA technology. Furthermore, objective establish Index Biotic Integrity (IBI) system. study, we sampled 18 sampling sites three time periods, reference were selected based number factors, including distance between site outfall, extent vegetation cover, degree anthropogenic disturbance. The then compared over different periods (before, during, after season). analysis enabled construction indicators, considered fish, benthic invertebrates, zooplankton, phytoplankton, fungi, microbial (It should be noted due overlap information weak indication final indicator system will not include all taxa, but only some them). results demonstrated scores disturbance exhibited notable differences both individual whole (p < 0.05), observed tendency increased from dam. Positive linear correlation IBI concentrations sites. outcomes satisfactory indicative capacity spatial temporal consistency, providing reliable foundation ecosystem health assessment. successful application method offers novel insights tools future
