Question

How does sediment loss affect land and soil quality?

Answer 1

A natural process, which can take place due to water, wind, or other kinds of erosion is considered as sediment loss. However, when much of the sediment gets lost, it can even result in the weakening of the undermine ecosystems, foundations of homes, and even can lead to the destruction of landforms.

The loss of sediment influences the quality of soil and land as it signifies a loss in nutrients, which the land may require for doing vegetation. It can also result in flooding that can conduct toxins into the water bodies.

Answer 2

soil quality is at risk from a number of reasons, driven by a range of man-made and natural pressures including climate change, land use change, and land management practices.

Human activities have changed the character and the quality of our soils over time. We have destroyed protective vegetation cover and have kept soil bare for long periods of time. We also actively add nutrients and pesticides to soils and cover them with housing and infrastructures. All of these activities can impair, or even destroy, the ability of soil to carry out its essential functions.

Once soil is damaged or contaminated it can be extremely difficult, if not impossible, to restore. In some cases, soil can make themselves become sources of pullutants. These pullutants can make their way into watercourses affecting water quality.
