Preventing and managing erosion

What is soil erosion and soil degradation? Although soil erosion is a natural process, human activities over the past decades have greatly accelerated it. In fact, according to the UNESCO , land degradation is undermining the well-being of two-fifths of humanity, driving species extinct and intensifying climate change. Soil erosion is a gradual process of movement and transport of the upper layer of soil topsoil by different agents — particularly water, wind, and mass movement — causing its deterioration in the long term. In other words, soil erosion is the removal of the most fertile top layer of soil through water, wind and tillage. Soil erosion is a consequence of unsustainable land use and other disturbances, such as fire, mining, or intensive agricultural uses.

Soil Erosion by Wind: An Overview

Since , New Jersey has required the management of soil erosion and stormwater from virtually all non-agriculture, construction-based soil disturbances through its adoption of the NJ Soil Erosion and Sediment Control Act N. The plan must also ensure that erosion will not occur once construction is completed. These land disturbance activities include but are not limited to such things as residential and commercial development, transportation and utility infrastructure, public facilities and mining. District staff inspects these sites to verify compliance with the plan. Districts and the NJDA work cooperatively with local and state government as well as with the development community to ensure effective manage of soil and water resources during construction. The current edition of the Standards , revised in , contains 32 practices.

Physics of desertification pp Cite as. Wind erosion is a serious problem in many parts of the world. It physically removes the most fertile portion of the soil from the field, pollutes the air, fills road ditches, reduces seedling survival and growth, and lowers the marketability of many vegetable crops. Wind erosion also creates new desert landforms and landscapes. Wind erosion is generally worse in arid and semiarid climates. It can be a problem wherever soil, vegetative, and climatic conditions are conducive. Soil particles erode when shear stress exerted by the wind against the ground surface exceeds the forces tending to hold the particles in place.
