24 Αυγ 2018 · 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].
7 Φεβ 2020 · Soil erosion is agriculture’s enemy: a major environmental threat to sustainability and productivity with knock-on effects on the climate crisis and food security. This is particularly true for places with the highest risk of erosion, such as watersheds in Indonesia, India, the Philippines and more. In these areas, protecting against soil ...
Human activities have accelerated soil erosion and landscape change in many areas. Here the authors show how rates of erosion, sediment transfer and alluvial sedimentation have increased by an order of magnitude across North America since European colonization, far exceeding the rates expected of natural processes.
31 Οκτ 2005 · Most of the time, the gullying processes are triggered by inappropriate cultivation and irrigation systems, overgrazing, log haulage tracks, road building and urbanization. As exemplified by recent examples from all over the world, land use change is expected to have a greater impact on gully erosion than climate change.
1 Φεβ 2017 · Both soil erosion and mass movement are two forms of land degradation and humans play important roles in these geomorphological processes. This paper reviews slope processes associated with mass movement and soil erosion and contributory factors, including physical and human agents.
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).
10 Ιαν 2018 · Here we show that for most of the past 12,300 years soil erosion and development were impacted differently by natural climate variability, as recorded by sediments deposited in Lake Dojran ...
