7 Φεβ 2020 · Soil erosion decreases soil fertility, which can negatively affect crop yields. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and rivers from flowing smoothly and can eventually lead to flooding.
24 Αυγ 2018 · Major Causes and Effects of Soil Erosion on People and the Environment. Soil erosion is the most serious precursor of soil degradation that comes with global implications. Nearly 10 million hectares of arable land are lost to erosion and other forms of soil degradation every year [1].
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
Soils that affect human health include natural soil, which usually has little anthropogenic contamination, and soils in agroecosystems, urban areas, mines, oil and gas extraction areas, landfill sites and other locations where anthropogenic contamination is more likely.
22 Ιουν 2021 · Definitions. Land degradation has been an elusive term in geographical literature and environmental studies because of its association with similar natural occurrences, such as deforestation, desertification, and soil erosion.
26 Νοε 2020 · Introduction. Human activities have significant impacts on landscape evolution via changes in sediment production, transport and storage 1, 2, 3, 4, 5, 6. In particular, agricultural practices...
24 Νοε 2023 · Soil erosion on arable land can be split into four main forms: water erosion, tillage erosion, wind erosion and harvest erosion, which we discuss here, plus piping, land levelling and explosion for which we refer the reader to the review by Poesen (2018).
