Erosion control strategies? Soil is a very important resource that allows the production of food, fiber, or forages. Despite it being a renewable resource, it renews slowly – generating three centimeters of topsoil takes 1,000 years. Therefore, protecting it is very important to bet on long-term, sustainable agricultural practices since one of the main issues associated with soil erosion is that it comes along a decrease in soil productivity. These productivity losses reduce the quantity and quality of the food we eat. A study based on the results of 40 soil associations reported that the effects of soil erosion on soil productivity were mostly the result of subsoil properties such as soil water availability, root growth or plow layer fertility – which impact yield results. In the end, with an unfavorable subsoil, erosion is easier and yields and productivity are more greatly affected.
Bits of sand are picked up and carried off by the wind, which can then blast the sides of nearby rocks, buffing and polishing them smooth. On the seashore, the action of waves chips away at cliffs and rakes the fragments back and forth into fine sand. Plants and animals also take a heavy toll on Earth’s hardened minerals. Lichens and mosses can squeeze into cracks and crevices, where they take root. As they grow, so do the cracks, eventually splitting into bits and pieces. Critters big and small trample, crush, and plow rocks as they scurry across the surface and burrow underground. Plants and animals also produce acids that mix with rainwater, a combination that eats away at rocks.
The abrasive action of sand and pebbles washed against shorelines is probably the most significant wave erosional activity. Particles are dragged back and forth by wave action, abrading the bedrock along the coast and abrading each other, gradually wearing pebbles into sand. Wave erosion creates retrograde, or retreating, shorelines with sea cliffs, wave-cut benches at the base of the sea cliffs, and sea arches—curved or rectangularly shaped archways that result from different rates of erosion due to varied bedrock resistance. Besides the back-and-forth transportation of materials by wave action, sediments are transported by the lateral movement of waves after they wash ashore (beach drifting) or by shallow-water transport just offshore, known as longshore currents. These transportational movements lead to deposition and the formation of prograde, or advancing, shorelines, bars, spits, bayhead beaches (a bayhead beach is formed between two headlands), and barrier beaches (a barrier beach parallels the shore).

Soil erosion, that is, the process that transforms soil into sediments, is one of the major and most widely spread forms of land degradation (Lal 2014; Weil and Brady 2017). It encompasses the destruction of the physical structure that supports the development of plant roots. Moreover, surface soil removal may result in substantial nutrient and water losses, as well as in the decrease of productivity and the increase of pollution of surface waterways. Soil erosion impacts thus the sustainability of ecosystems and the provision of ecosystem services. Soil conservation efforts address concerns with these impacts and meet the increasing needs for food and raw materials (Hurni et al. 2008).
Why Is Erosion Control Important? Without erosion control, your topsoil may lose its ability to hold nutrients, regulate water flow, and combat pollutants. In addition to affecting the ecosystem of nearby wildlife, residential properties and transportation systems can suffer long term damage. To combat the environmental problem of both erosion and sedimentation, certain methods must be practiced by construction companies.
