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.

Aug 23, 2024 · Soil erosion is the process where soil is removed from the Earth’s surface by natural forces such as wind and water, or through human activities. This can lead to the loss of fertile topsoil and affect land productivity.
Understanding the physical processes involved in water erosion is crucial for comprehending how water interacts with the soil, leading to various forms of erosion. These mechanisms include splash erosion, surface runoff, and subsurface flow, each contributing uniquely to the degradation of soil and alteration of landscapes.
Soil erosion occurs on agricultural soils through three main processes: wind, water and tillage erosion. Wind and water erosion occur naturally in the environment. However, these processes can be accelerated by farming activities such as summer fallow and annual crop production.
Soil erosion is a process in which the top fertile layer of soil is lost. Due to soil erosion, the soil becomes less fertile. The top layer of soil is very light which is easily carried away by wind and water.
