Land degradation

  1. 1. Made by – Aunj Raut Krishna Sashank LAND DEGREDATION
  2. 2. INTRODUCTION The change in the characteristic and quality of soil which adversely affect its fertility is called as Degradation. Land degradation is the most important environmental problem currently challenging sustainable development in many parts of the world. The problem is most acute where the environment is intrinsically vulnerable and where the population is losing control of its own resources.
  3. 3. Land degradation means: 1) Loss of natural fertility of soil because of loss of nutrients. 2) Less vegetation cover 3) Changes in the characteristic of soil. 4) Pollution of water resources from the contamination of soil through which water sweeps into ground or runoff to the water bodies. 5) Changes in climatic conditions because of unbalance created in the environment.

  10. 10. 1) Overgrazing refers to excessive eating of grasses and other green plants by cattle. It results into reduced growth of vegetation, reduced diversity of plant species, excessive growth of unwanted plant species, soil erosion, and degradation of land due to cattle movement.

  12. 12. EFFECTS OR IMPACTS INCLUDE: 1. Decline in the chemical, physical and/or biological properties of soil. 2. Reduced availability of potable water. 3. Lessened volumes of surface water. 4. Impacts on livestock and agriculture e.g. loss of animals due to dehydration, reduced yields. 5. Decline in productivity. 6. Water and food insecurity. 7. Biodiversity loss.
  13. 13. CONSERVATION MEASURES 1. Strip farming: It is a practice in which cultivated crops are sown in alternative strips to prevent water movement.
  14. 14. 2. Crop Rotation: It is one of the agricultural practice in which different crops are grown in same area following a rotation system which helps in replenishment of the soil.
  15. 15. 3. Ridge and Furrow Formation: Soil erosion is one of the factors responsible for land degradation. It can be prevented by formation of ridge and furrow during irrigation which lessens run off.
  16. 16. 4. Construction of bunds: This usually checks or reduces the velocity of run off so that soil support vegetation.
  17. 17. 5. Contour Farming: This type of farming is usually practiced across the hill side and is useful in collecting and diverting the run off to avoid erosion.
  18. 18. Sustainable Land Management The term SLM can be used to describe the utilisation of terrestrial resources (soils, plants, water, etc.) for the production of goods to satisfy changing human needs, without detriment to the long-term productive potential of these resources and their environmental functions.
  19. 19. Conclusion Land degradation occurs because of land poor management practices. In order to assess sustainable land management practices, the climate resources and the risk of climate- related natural disaster need to be documented. The use of climate information must be applied in developing sustainable practices. There is need to apply sustainable land management practices in field for conservation of land.
