Earth beyond six of nine planetary boundaries

Science Advances, Journal Year: 2023, Volume and Issue: 9(37)

Published: Sept. 13, 2023

This planetary boundaries framework update finds that six of the nine are transgressed, suggesting Earth is now well outside safe operating space for humanity. Ocean acidification close to being breached, while aerosol loading regionally exceeds boundary. Stratospheric ozone levels have slightly recovered. The transgression level has increased all earlier identified as overstepped. As primary production drives system biosphere functions, human appropriation net proposed a control variable functional integrity. boundary also transgressed. modeling different climate and land change illustrates these anthropogenic impacts on must be considered in systemic context.

A comprehensive geospatial database of nearly 100 000 reservoirs in China

Earth system science data, Journal Year: 2022, Volume and Issue: 14(9), P. 4017 - 4034

Published: Sept. 6, 2022

Abstract. With rapid population growth and socioeconomic development over the last century, a great number of dams/reservoirs have been constructed globally to meet various needs. China has strong economical societal demands for constructing dams reservoirs. The official statistics reported more than 98 000 in China, including nearly 40 % world's largest dams. Despite availability several global-scale dam/reservoir databases (e.g., Global Reservoir Dam database (GRanD), GlObal geOreferenced Database Dams (GOODD), Georeferenced global And Reservoirs (GeoDAR)), these insufficient coverage reservoirs especially small or newly ones. lack reservoir information impedes estimation water budgets evaluation dam impacts on hydrologic nutrient fluxes its downstream countries. Therefore, we presented Dataset (CRD), which contains 97 435 polygons fundamental attribute name storage capacity) based existing products, national basic geographic datasets, multi-source open map data, multi-level governmental yearbooks databases. compiled CRD total maximum inundation area 50 085.21 km2 capacity about 979.62 km3 (924.96–1060.59 km3). quantity decreases from southeast northwest, density hotspots mainly occur hilly regions large plains, with Yangtze River basin dominating count, area, capacity. We found that spatial accumulations are closely related China's implementation major policies. Finally, comparison GOODD, GeoDAR, GRanD significantly increased smaller 1 km2. provides comprehensive is expected benefit resources managements understanding ecological environmental across affected transboundary basins. publicly available at https://doi.org/10.5281/zenodo.6984619 (Song et al., 2022).

Vanadium in the Environment: Biogeochemistry and Bioremediation

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(39), P. 14770 - 14786

Published: Sept. 11, 2023

Vanadium(V) is a highly toxic multivalent, redox-sensitive element. It widely distributed in the environment and employed various industrial applications. Interactions between V (micro)organisms have recently garnered considerable attention. This Review discusses biogeochemical cycling of its corresponding bioremediation strategies. Anthropogenic activities resulted elevated environmental concentrations compared to natural emissions. The global distributions atmosphere, soils, water bodies, sediments are outlined here, with notable prevalence Europe. Soluble V(V) predominantly exists exhibits high mobility chemical reactivity. transport within media across food chains also discussed. Microbially mediated transformation evaluated shed light on primary mechanisms underlying microbial reduction, namely electron transfer enzymatic catalysis. Additionally, this highlights strategies by exploring their geochemical influences technical implementation methods. identified knowledge gaps include particulate speciation associated behaviors as well processes marine environments. Finally, challenges for future research reported, including screening hyperaccumulators V(V)-reducing microbes field tests approaches.
