Forests are one of the most natural resources on this earth . Covering the earth like a green blanket these forests not only produceinnumerable material goods, but also provide several environmental services which are essential for life. “Forests were the first temples of the Divinity, and it is in the forests that men have grasped the first idea of architecture .”PowerPoint Presentation: USES OF FOREST RESOURCES People began life on this planet as forest dwellers. They were food gatherers and dependent on forests for their basic needs:food,clothing and shelter. But they continued to depend on forests to meet a lot of their needs.

It is also called OVER-HARVESTING . Demand for Timber. Demand for cleared land. Demand for animal products. Demand for fuelwood. Short-term economic gains made by conversion of forest to agriculture, or overexploitation of wood products, typically leads to loss of long-term income and long term biological productivity.PowerPoint Presentation: DEFORESTATION Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. CAUSES Shifting Cultivation Development Project Demand for Fuelwood Use of Land for agriculture OvergrazingPowerPoint Presentation: CHIPKO MOVEMENT The movement is best known for its tactic of hugging trees to prevent them being cut down and to prevent commercial timber harvesting. Locally it is called as Angwal . Chipko means tree hugging or “embrace” as the villagers hugged the trees. Resistance to destruction of forests spread in the hills of Uttaranchal in1970’s First Chipko action March 1974 in Reni village.PowerPoint Presentation: Success Of Chipko Movement The movement has spread to many states in the country. It stopped felling of trees in the Western Ghats and the Vindhyas . Generated pressure for formulation of a natural resource policy. Achieved a major victory in 1980 with a 15-year ban on green felling in the Himalayan forests More than 1,00,000 trees have been saved from excavation. Started protecting forest slopes and Restoring bare ones. Villagers paid special attention in care of the trees and forest trees are being used judiciously.PowerPoint Presentation: TIMBER EXTRACTION Extraction of timber is a major intervention in forest stocks and inevitably causes disturbance to flora and fauna . Extraction often also involves the creation of forestry roads, which have a fragmenting effect . In terms of landscape permeability, alternative methods of extraction (e.g. cable logging, horse logging etc.) should be given preference . The use of horses, in particular, causes less damage to stands and regeneration areas, and protects the forest floor as it does not leave tracks or cause widespread compaction of soils or oil pollution etc .PowerPoint Presentation: MINING Mining is the extraction of valuable minerals or other geological materials from the earth, from an ore body, vein or (coal) seam. The term also includes the removal of soil. Mining and its associated activities require removal of vegetation along withunderlying soil mantle and overlying rock masses,which results in Topography and destruction of landscape in the area. Mining from shallow deposits is done by surfacemining while that from deep deposits is done by sub-surface mining. Large scale deforestation has been reported in Mussorie and Dehradun valleydue to indiscriminating mining of various minerals over a length of about 40 Km . Mining of magnesite and soap –stones have destroyed 14 ha of forest in hill slopes of Khirakot , Kosi valley,Almora . Mining of radioactive minerals in Kerala, Tamil Nadu and Karnataka areposing similar threats of deforestation.PowerPoint Presentation: DAMS AND THEIR EFFECTS ON FORESTS AND PEOPLE Big dams and rivers valley projects have multi-purpose uses and PanditJawaharlal Nehru used to refer to these dams and valley projects as “Temples of modern India ”. Big dams have been in sharp focus of various environmental groups all over theworld which is mainly because of several ecological problems includingdeforestation and socio-economic problems related to tribal or native peopleassociated with them The Silent valley hydroelectric project was one of the first such projects situatedin the tropical rain forest area of Western Ghats which attracted much concern of the people For building big dams, large scale devastation of forests takes place whichbreaks the natural ecological balance of the region. Floods, droughts andlandslides become more prevalent in such areas. Forests are the repositories of invaluable gifts of nature in the form of biodiversityand by destroying them (particularly, the tropical rain forests) we are going to lose these species even before knowing them.PowerPoint Presentation: Submitted To: Dr. Praveen Submitted By: Amrit Pal Singh BCA 1 st Sem (AIIT) You do not have the permission to view this presentation.
