Estimates of Dust Emissions and Organic Carbon Losses Induced by Wind Erosion in Farmland Worldwide from 2017 to 2021

Wind erosion can cause high dust emissions from agricultural land and lead to a significant loss of carbon nutrients the soil. The balance farmland soil is an integral part cycle, especially under current drive develop carbon-neutral practices. However, amount global lost due wind unknown. In this study, were estimated emission inventory (0.1° × 0.1°, daily) built using improved Community Multiscale Air Quality Modeling System–FENGSHA (CMAQ-FENGSHA), organic losses by combining with concentration data. average annual 2017 2021 1.75 109 g/s. Global are concentrated in UK, Ukraine, Russia Europe; southern Canada central US North America; area around Buenos Aires, capital Argentina, South northeast China Asia. was 2970 Gg for 2017–2021. spatial distribution roughly consistent that emissions, which mainly world’s four major black regions. These estimates essential references inform responses conservation.
