Washes away nutrient-rich topsoil from lands
actu.epfl.ch
- A natural process affected by human activities, erosion causes soil or layers of soil to be moved or worn away. Erosion is a potential environmental issue because it usually washes away nutrient-rich topsoil from lands. This can prevent future generations of plants from growing in eroded areas.

Soil is a natural resource that may look robust and endless, but is in fact the fragile product of thousands of years of formation. Topsoil, which lies closest to the surface of the land, contains essential nutrients for crops. It is this layer of soil that is endangered by wind and water erosion. Soil erosion decreases soil fertility, which can ne...
Erosion degrades land, which means it can support fewer plants that can take in climate-warming carbon dioxide. Soils themselves could potentially sequester enough greenhouse gases in a year to equal about 5% of all annual human-made GHG emissions. Better land management can help keep soils intact so they can grow more carbon-sucking vegetation. Th...
We’re already seeing the risks of soil erosion play out around the world. Jakarta’s deadly floods earlier this year are a prime example. Eroded sediments from further upstream clogged Jakarta’s rivers and canals, causing them to overflow. Similar erosion-related floods have occurred in many other countries, such as Colombia, India, the Philippines ...
1. Use Soil-friendly Agricultural Practices
Terraced farming needs to be implemented to make hillside agriculture manageable. Terraces prevent erosion and allow more water to flow to crops. In addition, hillside farm fields need full crop cover to help keep the soil in place. This can be accomplished by intercropping, which means growing two crops together in the same field, such as planting rows of maize or soybean between rows of oil palm trees. For smallholders, agroforestry systemswhere a diverse set of crops, including trees, are...
2. Offer Incentives for Land Management
Although the science of sustainable land management has been gaining support, the socio-economic context often makes implementation difficult. Sustainable land practices need to be financially viable for farmers. Anti-erosion measures have a median cost of $500 per hectare, a considerable investment for a farmer. Governments and banks must help farmers get access to credit and support in implementing erosion prevention. This is not only a good deal for the farmer, but for the whole community....
3. Prevention AND Rehabilitation
The key to managing and reducing soil erosion is to rehabilitate already-damaged land, stop further degradation and put erosion-preventative measures at the core of land management policy. In this way, we can help prevent hunger and mitigate the climate crisis. To learn more about WRI's work restoring eroded soils, click here.

Soil erosion, or the loss of all that important stuff, is a natural phenomenon caused by water and wind but can become more of a problem as humans inhabit and develop more of the planet. If unchecked, erosion can strip away valuable soil and negatively affect the water we consume, our ability to grow food, and the plants, animals, and land ...
Soil erosion reduces cropland productivity and contributes to the pollution of adjacent watercourses, wetlands and lakes. Soil erosion can be a slow process that continues relatively unnoticed or can occur at an alarming rate, causing serious loss of topsoil.
Erosion is the wearing away of the earth’s surface by the action of natural forces, for example, water, wind and glacial ice. The loose and dissolved materials move from one location to another. Erosion should not be confused with weathering.
