In light of the crises and disasters that occur for forests, the Food and Agriculture Organization of the United Nations advised the rehabilitation of forests through restoration of local plants and the reclamation of used and degraded lands for other purposes, and also replacement, which is the most extreme type of rehabilitation.
With regard to rehabilitating forests in the Kingdom, the advisor to the Undersecretary of the Ministry of Environment, Water and Agriculture for Agriculture, Dr. Ibrahim Aref, stated that the intervention could be done by improving the sites for cultivation, and by planting seedlings of juniper, talc, thistle, and dark olives (wild olives), which is important and fast-growing, and bears fires compared to «juniper And Al-Talh.
Forest rehabilitation theories
Aref explained that there are three global theories in forest rehabilitation: The first is based on not interfering with degraded sites and leaving them to nature, as they will return to what they were after the effects have passed, and the second differs from the first, where the intervention is very simple and within certain limits, and in most cases It lies in the restoration and breeding of native species, but with caution.
While the third stipulates that intervention in the forest takes place if the deterioration has caused a major change or it is difficult to restore it as it was, and the nature of the area is often dry and little rainy, and therefore intervention must be done with short-term plans (removing dead and burning trees and protecting the site from long grazing) And long-term (implementation of an applied rehabilitation program, which includes rain harvesting in many ways, cultivation of native species capable of growing in difficult conditions, as well as the introduction of environmentally equivalent species, and the selection of fast-growing, and sometimes species that tolerate fires in the future).
“Aref” added that it is necessary to cultivate forests, whether degraded or not, to preserve the soil, explaining that most of the local species such as juniper and talmum can be easily cultivated, but they must be multiplied in the nursery and transported according to their age and length.
An effective solution
Forest rehabilitation, when properly implemented, helps restore ecosystems, create conditions and generate income. It is an effective solution to climate change, based on nature and its parent body, and preserving and enhancing natural ecosystems within the landscape. Among the most important conclusions to rehabilitate forests are planting plants appropriate to the nature of the state’s climate and the nature of wildlife in it, and among the solutions is to increase awareness and change human behaviors.
Forests around the world
Forests cover an area of 4.06 billion hectares in the world, including natural, cultivated or cultivated forests, and forests are concentrated in the tropics, subtropical and northern regions of the world. According to the statistics of the Food and Agriculture Organization of the United Nations, 93% of the world’s forests are naturally regenerated forests, and 7% are planted forests.
The area of renewable forest has declined naturally since 1990 with the decrease in the rate of forest loss, but the area under cultivation has expanded by 123 million hectares.
