Degradation of vegetation
Environmental cover is one of the most important environmental components that play a major role in preserving the ecological balance, and it includes all the plants on the planet from forests, forests, mosses, gardens, large or small wild plants, trees and shrubs that arose naturally on their own without human intervention.
The importance of vegetation
- It is considered the basic rule in the food pyramid for all living things.
- It is considered the most important environmental system; Because it contains all kinds of plants that absorb carbon dioxide during the metabolism process, produce oxygen necessary for breathing, and reduce global warming.
- It purifies the air, removing toxic gases, dust, and harmful substances suspended in the air.
- Maintains a suitable temperature for life, especially when reducing the temperature difference between day and night.
- Maintains cycles of organic and mineral elements in the soil.
- Maintains soil moisture and groundwater circulation.
- It prevents the phenomena of erosion and erosion of soil and terrain.
- It regulates wind, clouds and rain movement, and their distribution over the earth's surface.
- It provides the human being with natural materials that he uses in food, clothing, pharmaceutical industry, manufacturing raw materials and raw materials.
Degradation of vegetation
The degradation of vegetation cover is one of the most important environmental problems that the world faces as a result of the disruption of the relationship between man and the environment. With the increase in population and technological progress, the demand for natural environmental resources has increased, leading to their depletion and sabotage of their systems. Among the most important causes of the deterioration of vegetation cover are:
- Animal husbandry and overgrazing.
- Passive, indiscriminate and unregulated logging in forests, and use them for commercial purposes; Like charcoal and furniture.
- The migration of people from the countryside, and thus the neglect of agricultural lands and their degradation.
Damage to vegetation degradation
- Changes occur in the earth's climate and geography.
- The problem of global warming is exacerbating.
- Increase in soil erosion and the formation of torrents.
- Failure to take advantage of rainwater, and to prevent its infiltration into the ground to recharge the groundwater.
- Drought and desertification.
- Deprivation of the land from its weeds.
- Reduces biodiversity, as it is home to wildlife.
Methods of vegetation development
- Study and evaluation of natural resources in vegetation areas, and take the necessary measures to develop and utilize them well.
- Replant extinct or endangered plants in their original habitat.
- Preparing detailed maps of the soil and its natural vegetation contents using satellite images, in order to identify their characteristics, classification and production capabilities.
- Paying attention to scientific research, and cooperating with organizations working in the field of environmental development and protection by holding scientific seminars and conferences.
- Follow up the phenomenon of vegetation degradation by periodically comparing satellite images during different periods.
- Stopping rain-fed or irrigated crops in vegetation areas, and directing these crops towards areas designated for cultivation, appropriate in terms of climate and conditions.
- Spread health awareness among the population of the environmental, economic and medical importance of vegetation cover, and the consequences of its deterioration, and enact strict laws to deter violators.
