How is erosion bad for the environment




















Queensland farmers have been cultivating the land since the s. However, early farmers were not aware that some of their farming practices were causing erosion. By the s, soil erosion was seriously threatening the productivity of fertile cropping areas such as the Darling Downs and the Inland Burnett. If nothing is done to protect the soil, losses can be very high.

Soil erosion has been so severe that some areas of Queensland are now unsuitable for cropping. Soil losses from unprotected cultivation in upland cropping areas of the Darling Downs can average between 20 and 60 tonnes per hectare per year.

Steep, unprotected cropping lands in tropical areas can lose up to tonnes of soil per hectare per year. Eroded soil, which can contain nutrients, fertilisers and herbicides or pesticides, can be deposited where there is a reduction in the slope of the land. This can be in sediment traps, along contour banks, or in grassed waterways, dams or wetlands. Catena Verlag Cremlingen-Destedt, Germany 37— Singh J. Solliday, L. Southgate M. Speth, J.

As a result of erosion over the past 40 years, 30 percent of the world's arable land has become unproductive. About 60 percent of soil that is washed away ends up in rivers, streams and lakes, making waterways more prone to flooding and to contamination from soil's fertilizers and pesticides.

Soil erosion also reduces the ability of soil to store water and support plant growth, thereby reducing its ability to support biodiversity.

Erosion promotes critical losses of water, nutrients, soil organic matter and soil biota, harming forests, rangeland and natural ecosystems.

Erosion increases the amount of dust carried by wind, which not only acts as an abrasive and air pollutant but also carries about 20 human infectious disease organisms, including anthrax and tuberculosis. Story Source: Materials provided by Cornell University.
