• On fertile soils, soil degradation tends to be compensated by fertilizer application • Many areas, populated by a large percentage of the people are in a critical state, where fertility loss needs urgently to be compensated by new external impacts and/or soil...
Since soil degradation can cause a big impact on the world, here are some current solutions that people are trying to incorporate. One way is by creating shelterbelts. Shelterbelts are rows of trees planted as a windbreak to reduce soil erosion of agricultural land (REE, 2016). By doing this, it can help prevent landslides and floods.

  • The surface water flows that cause sheet erosion rarely flow for more than a few metres before concentrating into rills. degradation in some regions, including the NSW north coast due to its intense rainfall events. Types of mass movement include soil creep, earth flow, slumps, landslips, landslides and avalanches. Factors increasing mass movement include erosion or excavation …
  • Soil quality decline is one of the main causes of land degradation and is considered to be responsible for 84% of the ever diminishing acreage. Year after year, huge acres of land lost due to soil erosion, contamination and pollution. About 40% of the world’s agricultural land is severely diminished in quality because of erosion and the use of chemical fertilisers, which prevent land from
