Substantial role of check dams in sediment trapping and carbon sequestration on the Chinese Loess Plateau

Communications Earth & Environment, 2023
Check dams on the Chinese Loess Plateau are estimated to trap and bury approximately 10.2 ± 0.6 Pg of eroded sediment and 21.6 ± 9.9 Tg of organic carbon over the past 50 years, according to large-scale field surveys and remote sensing.

Soil Erosion in Taiwan

Agriculture, 2023
Soil erosion is a complex process involving material detachment, transportation (mainly by water, occasionally by wind), and eventual deposition when energy wanes. Human activities like tillage and construction can exacerbate soil erosion. Various forms of water erosion, such as sheet erosion, pedestal erosion, rills, piping, and gullying, are ...

Reservoir theory for studying the geochemical evolution of soils [PDF]

, 2010
[1] Linking mineral weathering rates measured in the laboratory to those measured at the landscape scale is problematic. In laboratory studies, collections of minerals are exposed to the same weathering environment over a fixed amount of time. In natural

Integrated Ecological Risk Assessment of the Agricultural Area under a High Anthropopressure Based on Chemical, Ecotoxicological and Ecological Indicators

Agriculture, 2023
Agricultural land is often located close to highly urbanised/industrialised areas and is subject to continuous anthropogenic pressure associated with the emission of many pollutants, ultimately deposited in the soil.

Spatiotemporal Dynamics and Transboundary Differences in Fractional Vegetation Cover in the Red River Basin from 2000 to 2023

Remote Sensing
The vegetation cover in the Red River Basin (RRB) has undergone considerable changes over the past 20 years. Identifying vegetation cover and its transboundary differences is crucial for assessing the ecological health of the region.

Assessment of soil erosion in olive orchards (Olea europaea L.) under cover crops management systems in the tropical region of Brazil [PDF]

, 2020
In the tropics, water erosion is one of the most important factors leading to the degradation and deterioration of agricultural land. Olive orchards have a low canopy coverage, especially during the first years after planting, due to the low density of ...
