Which is an anthropogenic reasons of land degradation?

Human interventions which are causing land degradation are (1) deforestation, (2) overgrazing by livestock, (3) mismanagement of agricultural land, (4) overexploitation of the vegetative cover for domestic use, and (5) (bio)industrial activities.

What is meant by forest degradation?

Forest degradation occurs when forest ecosystems lose their capacity to provide important goods and services to people and nature. Over half of the tropical forests worldwide have been destroyed since the 1960s, and every second, more than one hectare of tropical forests is destroyed or drastically degraded.

Why is land degradation a problem?

Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity, the environment, and its effect on food security and the quality of life. The productivity of some lands has declined by 50% due to soil erosion and desertification.

What is land degradation and its effects?

Land degradation is a concept in which the value of the biophysical environment is affected by one or more combination of human induced processes acting upon the land. It literally refers to the impairment of natural quality of soil component of any ecosystem.

What are the 5 causes of land degradation?

Nine Main Causes of Land Degradation are as follows:

  • 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 3 main causes of forest degradation?

The most common pressures causing deforestation and severe forest degradation are agriculture, unsustainable forest management, mining, infrastructure projects and increased fire incidence and intensity.

What are the three main sources of forest degradation?

Human activities that drive forest degradation include overgrazing, demand for fuel wood and charcoal, excessive logging and human-induced fires. Natural causes of degradation include insect pests, storm damage and natural fires.

What are the reasons for forest degradation?

The major causes of forest decline include: 1) pollution from both industry and agriculture, 2) stress factors, e.g., desiccation, 3) changes in stand dynamics, 4) decline disease of forest or diseases of complex etiology, 5) degradation of productivity and/or soil fertility in pure plantation forests.

What are the types of land degradation?

Types of land degradation assessed For the purpose of this study, the many and varied processes of land degradation have been grouped into six classes: water erosion, wind erosion, soil fertility decline, salinization, waterlogging, and lowering of the water table.

Why land is considered an important resource?

Answer: Land is considered an important resource because it can be put to use for various purposes like agriculture, forestry, mining, building houses, roads and setting up of industries.

Which two factors are responsible for land degradation?

Some of the factors responsible for land degradation are (i) loss of vegetation occuring due to deforestation (ii) unsustainable fuel wood and fodder extraction (iii) shifting cultivation (iv) encroachment into forest lands (v) forest fires and over grazing (vi) non-adoption of adequate soil conservation measures (vii)

How we can control land degradation?

  1. Afforestation.
  2. Proper management of grazing to control over grazing.
  3. Planting of shelter belts of plants.
  4. Stabilization of sand dunes by growing thorny bushes.
  5. Control of mining activities.
