Impact Of DeforestationOn Environment

Slide 2: 

Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a non forest use. Examples of deforestation include conversion of forestland to farms, ranches, or urban use . The term deforestation is often misused to describe any activity where all trees in an area are removed. What Is Deforestation?

Impact of Deforestation on Wildlife : 

Impact of Deforestation on Wildlife Wildlife is important for three main reasons:a) Animals help in balancing our ecosystem, food chain and acts as a food for us. So, it is really a shame for us to destroy their habitat. b) The financial value of wild species is important to the economies of several nations, as it provides many valuable substances like wood and other plant products, fibers, meat and other foods, and skins and furs. c) Wildlife helps in maintaining the balanced living systems of earth, which consequently ensures survival of life.

Impact of Deforestation on Wildlife : 

Impact of Deforestation on Wildlife As their habitat dwindles, many animals are forced to forage outside their traditional forest range and move into areas populated by humans. Fatal encounters with wild animals like elephants, venomous snakes, and big cats occur in and around degraded forest areas. Forest elephants have made news over the past few years with their deadly conflicts (deadly for both humans and elephants) in Asia. Several countries have embarked on innovative plans to keep elephants away from crops, while providing for their safety, though many farmers believe it easier to simply kill the offending animals.

Impact of deforestation onHumans : 

Impact of deforestation onHumans Deforestation results to global warming. It means increase of carbon dioxide which disturbs the atmospheric balance and raises temperature. This in turn effects human beings. it leads to skin cancer, eye diseases etc.Deforestation means clearing of forests which means cutting of plants. plants provide us with food. so when plants are cut, we do not get proper and healthy food this effects us adversly. so, deforestation has really bad impact on humans.

Impact of deforestation onSoil : 

Impact of deforestation onSoil Undisturbed forests have a very low rate of soil loss, approximately 2 metric tons per square kilometer (6 short tons per square mile). Deforestation generally increases rates of soil erosion, by increasing the amount of runoff and reducing the protection of the soil from tree litter. This can be an advantage in excessively leached tropical rain forest soils. Forestry operations themselves also increase erosion through the development of roads and the use of mechanized equipment. China's Loess Plateau was cleared of forest millennia ago. Since then it has been eroding, creating dramatic incised valleys, and providing the sediment that gives the Yellow River its yellow color and that causes the flooding of the river in the lower reaches (hence the river's nickname 'China's sorrow').

Impact of deforestation onSoil : 

Impact of deforestation onSoil Removal of trees does not always increase erosion rates. In certain regions of southwest US, shrubs and trees have been encroaching on grassland. The trees themselves enhance the loss of grass between tree canopies. The bare intercanopy areas become highly erodible. Tree roots bind soil together, and if the soil is sufficiently shallow they act to keep the soil in place by also binding with underlying bedrock. Tree removal on steep slopes with shallow soil thus increases the risk of landslides, which can threaten people living nearby. However most deforestation only affects the trunks of trees, allowing for the roots to stay rooted, negating the landslide.

Impact of deforestation onWater : 

Impact of deforestation onWater The water cycle is also affected by deforestation. Trees extract groundwater through their roots and release it into the atmosphere. When part of a forest is removed, the trees no longer evaporate away this water, resulting in a much drier climate. Deforestation reduces the content of water in the soil and groundwater as well as atmospheric moisture. The dry soil leads to lower water intake for the trees to extract. Shrinking forest cover lessens the landscape's capacity to intercept, retain and transpire precipitation. Instead of trapping precipitation, which then percolates to groundwater systems, deforested areas become sources of surface water runoff, which moves much faster than subsurface flows.

Impact of deforestation onWater : 

Impact of deforestation onWater Trees, and plants in general, affect the water cycle significantly: their canopies intercept a proportion of precipitation, which is then evaporated back to the atmosphere (canopy interception); their litter, stems and trunks slow down surface runoff; their roots create macrospores – large conduits – in the soil that increase infiltration of water; they contribute to terrestrial evaporation and reduce soil moisture via transpiration; their litter and other organic residue change soil properties that affect the capacity of soil to store water. their leaves control the humidity of the atmosphere by transpiring. 99% of the water absorbed by the roots moves up to the leaves and is transpired. So if there is deforestation none of these processes are possible

Impact of Deforestation on Atmosphere : 

Impact of Deforestation on Atmosphere Rainforests are widely believed by laymen to contribute a significant amount of world's oxygen although it is now accepted by scientists that rainforests contribute little net oxygen to the atmosphere and deforestation will have no effect on atmospheric oxygen levels. However, the incineration and burning of forest plants to clear land releases large amounts of CO2, which contributes to global warming. Scientists also state that, Tropical deforestation releases 1.5 billion tones of carbon each year into the atmosphere. So if deforestation goes on there will be no pure air also.

Impact of Deforestation onEconomy : 

Impact of Deforestation onEconomy Damage to forests and other aspects of nature could halve living standards for the world's poor and reduce global GDP by about 7% by 2050, a report concluded at the Convention on Biological Diversity (CBD) meeting in Bonn. Historically, utilization of forest products, including timber and fuel wood, has played a key role in human societies, comparable to the roles of water and cultivable land. Today, developed countries continue to utilize timber for building houses, and wood pulp for paper. In developing countries almost three billion people rely on wood for heating and cooking. The forest products industry is a large part of the economy in both developed and developing countries. Short-term economic gains made by conversion of forest to agriculture, or over-exploitation of wood products, typically leads to loss of long-term income and long-term biological productivity. West Africa, Madagascar, Southeast Asia and many other regions have experienced lower revenue because of declining timber harvests. Illegal logging causes billions of dollars of losses to national economies annually.

Impact of Deforestation onEconomy : 

Impact of Deforestation onEconomy The new procedures to get amounts of wood are causing more harm to the economy and overpower the amount of money spent by people employed in Rapidly growing economies also have an effect on deforestation. Most pressure will come from the world's developing countries, which have the fastest-growing populations and most rapid economic (industrial) growth. In 1995, economic growth in developing countries reached nearly 6%, compared with the 2% growth rate for developed countries.”As our population grows, new homes, communities, and expansions of cities will occur. Connecting all of the new expansions will be roads, a very important part in our daily life. Rural roads promote economic development but also facilitate deforestation.About 90% of the deforestation has occurred within 100 km of roads in most parts of the Amazon.
