Forestation and Regeneration of the Soil

Questions?

  • What should be done to reverse the trend of planed deforestation?
  • What can we do as individuals to reverse the public opinion regarding this issue?
  • Wat were the best laws that should be used to reverse desertification and restoration of land and forests?
  • Does it matter the opinion of a person that has no ownership of land covered by  forests in reversing the deforestation?
  • What is the effect of ownership on preserving the trees and forests?
  • Does it matter what type of trees are replanted? I do not think it matter as long as there are trees that fix the soil. I believe that fruit trees are better.
  • What is the ideal type of ownership for keeping the forests alive?
Tree Forest

Tree Forest

Reforestation can be used to improve the quality of human life by soaking up pollution and dust from the air, rebuild natural habitats and ecosystems, mitigate global warming since forests facilitate biosequestration of atmospheric carbon dioxide.

Mechanical degradation of the soil is a consequence of movement and visit of animals, either directly by trampling (surface compacting of the soil), or indirectly as a result of partial or total disappearance of plant cover (wind and water erosion). Mechanical degradation of the soil is produced in areas much frequented by livestock, but is particularly worrying in areas subject to major climatic constraints, especially sub-arid areas. This is one of the causes of desertification.

Land Regeneration Techniques

Fencing
Protection for a longer or shorter period of time of a plot or area with a view to removing it from all forms of exploitation (people and herds); to be effective, this requires a long period which should not be less than ten years.
Prevention of surface erosion can be done in different ways:
Spreading of dead wood or big plant debris on bare surfaces: dust and organic debris are trapped by these branches which filter the wind. This is a fast and fairly effective method of rehabilitation. It can only be recommended in wooded areas or places where it is easy to make hay.
Stone walling along the contours, or at least perpendicular to the line of the steepest slope with: spacing 30 m or more depending on slope and state of the area; use on sites where there are resources nearby and in difficult areas where other techniques cannot be used.
Construction of small earth dikes, along the contours, or preferably in crescent formations placed to retain water run-off. Improving water infiltration enables progressive establishment of vegetation.

Re-vegetation
Sowing in pockets: in a hole 3 cm deep dug with a hoe, a few seeds per pocket are sown and covered with a fine layer of sand lightly packed. By sowing every 30 cm in all directions, it is possible to establish 100,000 pockets per hectare.
