What Are The Consequences Of Soil Erosion – Erosion is a serious problem in the United States and around the world. According to the Federal Emergency Management Agency (FEMA), the US coastline loses 1 to 4 feet each year due to erosion. The consequences have environmental and economic costs. For ecosystems, erosion translates into habitat loss as coastal wetlands degrade. Plants and wildlife that depend on these ecosystems are adversely affected by erosion. Economically, the loss of these ecosystems makes coastal areas more vulnerable to damage from tropical storms and storm surges.
One of the main causes of erosion is urban development. Habitat replacement often results in an increase in the number of impervious surfaces such as roads, parking lots, and sidewalks. Vegetation usually slows down the flow of surface water. Impermeable surfaces increase water flow. Water can move faster and in greater quantities. This causes water to overflow the rivers, causing erosion in vulnerable parts of the ecosystem.
What Are The Consequences Of Soil Erosion
Erosion removes topsoil from the ground, often removing the seed bank that exists in the soil. In addition, it can lead to toxins entering waterways from the use of pesticides and fertilizers. Erosion also carries the possibility of introducing other pollutants into water resources. Heavy metals and toxins are dormant in wetlands as part of the sediment. Erosion breaks down these layers and releases these pollutants into surface waters. Effects are measured based on the toxicity of chemicals and compounds that enter the water.
Effects Of Soil Erosion
Sediment has other negative consequences for water resources. Excess sediment negatively affects streams and lakes by obstructing filter feeders. These aquatic organisms feed on clean water. Effects on these life forms can potentially affect all aquatic life in the ecosystem by removing compounds lower down the food chain.
As erosion continues, so does the risk of flooding. Without adequate habitat and increasing impervious surfaces, more and more areas are vulnerable to flood risk. According to Flood Smart, any area — regardless of location — is at risk. Erosion compounds the problem and so do the costs of flooding.
The best solution to prevent soil erosion problems is to preserve and restore habitat. For example, planting buffer strips along the banks of streams and other bodies of water helps keep shoreline soils intact, thus preventing erosion. Wetland restoration protects ecosystems most vulnerable to soil erosion, such as floodplains, by absorbing and slowing excess water flowing over land surfaces.

Effects Of Soil Erosion In The Study Area After Intensive Rainfall….
Soil erosion is a serious threat to sustainable development and productivity with direct implications for the climate crisis and food security. This is especially true in places that are most at risk of erosion, such as watersheds in Indonesia, India, the Philippines, etc. In these areas, protecting against soil erosion through sustainable land management can solve many problems. Here’s a deeper look at the causes of soil erosion and how to deal with it:
Soil is a natural resource that may seem reliable and endless, but in reality it is a fragile product of millennia of formation. The upper layer of the soil, which is closer to the surface of the earth, contains nutrients necessary for agricultural crops. It is this layer of soil that is threatened by wind and water erosion. Soil erosion reduces its fertility, which can adversely affect the yield of agricultural crops. It also sends soil-saturated water downstream, which can form heavy layers of sediment that impede the smooth flow of streams and rivers and can ultimately lead to flooding. Once soil erosion has occurred, it is likely to happen again. This is a global problem. Soil is being eroded faster than it is being formed, making land unsuitable for agriculture, a particularly serious problem in a world where the population is expected to exceed 9 billion by mid-century. Smart land management is a must.
Erosion degrades the land, which means fewer plants can grow on it to absorb climate-warming carbon dioxide. Soils alone can potentially absorb enough greenhouse gases in one year to equal about 5% of all annual anthropogenic GHG emissions. Better land management can help keep soils intact so they can produce more carbon-sucking plants. This is already happening in China, where the Grain for Green project in the Yellow River basin has conserved soil and water and reduced carbon emissions. On the other hand, uncontrolled climate change can increase erosion. In the report of the Intergovernmental Panel on Climate Change (IPCC) it was established that during cultivation without conservative methods, the soil is eroded 100 times faster than it is formed. The risk of erosion will be even greater in the future due to temperature changes caused by emissions, with further reductions in agricultural production, land values and human health.
We are already seeing the risks of soil erosion around the world. The deadly floods in Jakarta earlier this year are a good example. The washed-out sediments upstream clogged Jakarta’s rivers and canals, causing them to overflow. Similar erosion-related flooding has occurred in many other countries, including Colombia, the Philippines, India, and the Democratic Republic of the Congo.

Soil erosion is not only an environmental problem; it also takes a huge toll on the economy. One study estimated global economic losses from soil erosion at approximately $8 billion due to reduced soil fertility, reduced crop yields, and increased water use. Another study found that soil erosion in Sleman, a district in Java, costs 17% of the average farmer’s net income per hectare of farmland. America’s agricultural sector loses about $44 billion a year to erosion. This value includes productivity loss along with sedimentation and water pollution. Lost farm profits are estimated at $100 million a year.

Terrace farming should be introduced to make hillside farming manageable. Terraces prevent erosion and allow more water to reach crops. In addition, agricultural fields on hillsides require full crop cover to keep the soil in place. This can be achieved by growing two crops together in the same field, such as planting corn or soybeans between rows of oil palm trees. Agroforestry systems, in which a variety of crops, including trees, are grown together can be effective for small landowners. Access to manure improves soil organic matter, which prevents erosion. Finally, alternating deep-rooted and shallow-rooted crops improves soil structure while reducing erosion.
While the science of sustainable land management gains support, the socio-economic context often complicates implementation. Sustainable land practices must be financially viable for farmers. Erosion control measures cost an average of $500 per hectare, a significant capital investment for the farmer. Governments and banks should help farmers access credit and support to implement erosion prevention measures. This is good business not only for the farmer, but also for the whole community. The cost of preventing erosion is much lower than the cost of restoring and rehabilitating the land, which one source estimated at $1,500 to $2,000 per hectare. Another source found that it could reach $15,221 per hectare.

The key to managing and reducing soil erosion is to rehabilitate already damaged land, stop further degradation and put erosion prevention measures at the heart of land management policy. In this way, we can help prevent hunger and mitigate the climate crisis.
