What are the causes of soil degradation?

Soil degradation causes include agricultural, industrial, and commercial pollution; loss of arable land due to urban expansion, overgrazing, and unsustainable agricultural practices; and long-term climatic changes.

What are three main causes of land degradation?

Land Degradation: 9 Main Causes of Land Degradation

  • Deforestation: Forests play an important role in maintaining fertility of soil by shedding their leaves which contain many nutrients.
  • Excessive Use of Fertilizers and Pesticides:
  • Overgrazing:
  • Salination:
  • Water-logging:
  • Desertification:
  • Soil erosion:
  • Wasteland:

What are the causes of land degradation how we solve this problem?

Afforestation and proper management of grazing can help to check land degradation. Planting of shelter belts help in checking the sand causing land degradation near the deserts. Overgrazing can be checked and avoided. Stabilisation of sand dunes by growing thorny bushes can also check land degradation.

What are some of the impacts of land degradation?

Its impacts can be far-reaching, including loss of soil fertility, destruction of species habitat and biodiversity, soil erosion, and excessive nutrient runoff into lakes. Land degradation also has serious knock-on effects for humans, such as malnutrition, disease, forced migration, cultural damage, and even war.

How does soil degradation affect humans?

Soils that contain substances such as heavy metals, which may be toxic to humans, can pass those substances on to humans through crop uptake, leading to unsafe foods that compromise food security (Hubert et al. 2010; Brevik 2009a). Soil degradation over large areas may threaten food security.

What is the effect of soil What will you do to protect the community?

Answer. Answer: Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.

What are the examples of soil pollution?

Examples of the most common and problematic soil pollutants can be found below.

  • Lead (Pb)
  • Mercury (Hg)
  • Arsenic (As)
  • Copper (Cu)
  • Zinc (Zn)
  • Nickel (Ni)
  • PAHs (polyaromatic hydrocarbons)
  • Herbicides/Insecticides.
