Compromises of a Growing World With the world growing at a pace hard to match, the increasing need for space is turning out to be an area of concern. Deforestation in simple term means the felling and clearing of forest cover or tree plantations in order to accommodate agricultural, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose. Over the last century the forest cover around the globe has been greatly compromised, leaving the green cover down to an all time low of about 30 per cent.
Destruction of forest is called deforestation. Deforestation has serious effect on human life and environment. According to a survey of forest department, India has about 75 million hectares of forest area. Recently collected satellite imagery data have revealed that only about 17 per cent area is covered by forest.
India is loosing 1. In the hilly region deforestation is so acute that economy and ecology of the area are severely affected. The original vegetation of Himalaya has been greatly destroyed which has resulted in gradual loss of the natural habitat and is posing a threat to natural resources.
Due to overpopulation, industrialization, urbanization, road construction, mining and other developmental activities the natural habitats of the flora and fauna are disturbed Deforestation a general overview essay have caused tremendous pressure on the living resources.
Many plant and animal species are on the verge of extinction or endangered. Forest destruction may also be caused by several adverse factors as landslides, drought, flood, storm, earthquakes, diseases, water and air pollution and human interferences.
Other adverse factors such as lack of stable soil, aridity, swampiness, biotic agencies, commercial exploitation, etc. Natural diversity of India is one of the richest in the world which is disappearing gradually due to aforesaid factors.
According to FAO report, the annual deforestation rate in India was 0. According to Ravindra Nath and Hall 1. Inthe total afforested area in India was According to Khoshoothe total area under forest in the world was about million ha.
Inby it was reduced to million ha. The destruction of forest cover in the ecologically sensitive Himalaya region has already started showing adverse impact in the form of increasing shortage of water, recurrent landslides, increasing flood, high sedimentation in the rivers, shortage of fuel and fodder and decrease in grazing land Due to deforestation the life supporting systems are disturbed.
Underground water table is progressively going deeper and deeper. Large area of the land becomes affected by drought and wells, tube- wells, lakes, ponds etc. In Kumaon and Garhwal Himalaya the oak forests are maintaining general environment and villagers depend to a great extent for fodder, fuel and some other necessities on these forests.
But now oak forests are being destroyed to meet the ever increasing demands of the people. This has resulted marked changes in the environmental conditions. Consequently, the herbal vegetation and microbial community associated with oak are destroyed.
This may lead to the loss of medicinal herbs and shrubs associated with oak. The availability of fodder will be reduced and the age-old animal link in the hill ecosystem would be broken.
At the Earth Summit in Rio de Janeiroissue related to deforestation was a major concern. The sustainably extractable quantity of fuel wood from Indian forests is far below the requirement of the population.
Livestock population in India is greater than can be sustainably supported by the available land and forest resources.
The demand for industrial wood and other wood, part of which is currently being met by imports, will continue to rise with industrial and economic growth.
Unregulated and increased harvesting of non-wood forest produce will result in loss of biodiversity. Expansion of protected area network will result in increasing pressures on the existing productive forests.
The different causes of deforestation are as follows: Overgrazing in forests destroys newly regenerated growth.
It also makes soil more compact and impervious. Soil becomes less fertile due to destruction of organic matter. Seeds of certain species do not germinate in excessively grazed soils which results in reduction of species.Deforestation has so many negative consequences on the environment.
One of the most immediate effects is the loss of habitat of many species of animals. Thus, deforestation can alter the earth’s biodiversity making a lot or rare species even more extinct.
