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 terms, means the felling and clearing of forest cover or tree plantations to accommodate agricultural, industrial or urban use.
What is deforestation? What is the definition of deforestation and why is deforestation happening? Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since , deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate. Multiple factors, either of human or natural origin, cause deforestation.
Deforestation is one of the major causes to the environmental degradation which is affected by the agents like small farmers, ranches, loggers and plantation companies.
There is a broad consensus that expansion of cropped areas and pastures are a major source of deforestation. The loss forest cover influences the climate and contributes to a loss of biodiversity. The economic activity is adversely affected by siltation, flooding, soil degradation and reduced timber supplies.
Thus, in turn, threatens the livelihood of people. Conversion of forests to agricultural land to feed growing needs of people. There are an estimated million people living as shifting cultivators who practice slash and burn agriculture and are supposed to clear more than 5 lakh ha of forests for shifting cultivation annually.
Which supplies the world market with woods such as meranti, teak, mahogany and ebony destroys trees as well as opening up forest for agriculture. Cutting of trees for fire wood and building material, the heavy lopping of foliage for fodder and heavy grazing of saplings by domestic animals like goals.
This causes environmental impacts like erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil.
Contamination resulting from leakage of chemicals can also affect the health of the local population if not properly controlled. Extreme examples of pollution from mining activities include coal fires, which can last for years or even decades, producing massive amounts of environmental damage. The needs also increase and utilize forests resources. To meet the demands of rapidly growing population, agricultural lands and settlements are created permanently by clearing forests.
Since Industrialization and Urbanization needs land to grow, so major amount of forest lands are cut in order to promote Industrialization and Urbanization. This creates harmful effect on environment and forest ecological balance. For building big dams, large scale devastation of forests takes place which breaks the natural ecological balance of the region.
Floods, droughts and landslides become more prevalent in such areas. Forests are the repositories of invaluable gifts of nature in the form of biodiversity and by destroying these we are going to lose these species even before knowing them. These species could be having marvelous economic or medicinal value. These storehouses of species which have evolved over millions of years get lost due to deforestation in a single stroke.
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, or by overpopulations of native or non- native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds.
Depending on the needs of the social group concerned, deforestation has made it possible for communities to be built. Forest makes way for residential houses, office buildings and factories. Governments are able to built reads to make trade and transport easier and therefore more convenient to residents.
Deforestation can also mean the conversion of forest land to productive land for agricultural uses. This results in better and more abundant production of food and materials, virtually eradicating periods of want and lack. Economically, deforestation has contributed much in giving many communities the opportunity to make positive changes in their times.
Unfortunately, the negative consequences of deforestation for outweigh its positive effects. Non suitability of deforested area for conservation. Most of the area that has undergone deforestation is actually unsuitable for long-term agricultural use such as ranching and forming. Once deprived of their forest cover, the lands rapidly degrade in quality, losing their fertility and arability.
The soil in many deforested areas in also unsuitable for supporting annual crops. Much of the grassy areas are also not as productive compared to more arable soils and are therefore not fit for long-term cattle grazing.
Heavy rainfall and high sunlight quickly damage the topsoil in clearings of the tropical rain forests. In such circumstance, the forest will take much longer to regenerate and the land will not be suitable for agricultural use for quite some time. Deforestation can results to watersheds that are no logger able to sustain and regulate water flows from rivers to steams. Trees are highly effective in absorbing water quantities, keeping the amount of water in watersheds to a manageable level.
The forest also serves as cover against erosion. Once they are gone, too much water can results to downstream flooding, many of which have cause disasters in many parts of the world. The fertile top soil is eroded and flooded into the lower regions, many coastal fisheries and coral reefs suffer from the sedimentation brought by the flooding. This results to negative effects in the economic viability of many business and fatalities in wildlife population.
This is probably most serious consequence of Deforestation. Put simply, it means the destruction and extinction of many plants and animal species, many of un-home remain unknown and whose benefits will be left undiscovered.
Fewer trees results an in secure future for forests workers. Deforestation can cause the climate to become extreme in nature. It increases CO2 concentration in atmosphere and contributes to global warming. The occurrence and strength of floods and droughts affecting the economy. It also leads to loss of future markets for ecotonism. The value of a forest is often higher when it is left standing than it could be worth when it is harvested.
The stress of environmental change may make some species more susceptible to the effect of insects, pollution and diseases. You must be logged in to post a comment. Sustainable Development of Water Resources. Leave a Reply Click here to cancel reply.
The collapse of the Classic Maya state is investigated from an ecological perspective. Settlement and palynological data from the Maya center of Copan, Honduras, are presented which indicate that substantial clearing of the upland pine forest had occurred prior to and during the abandonment of that urban center. A comparative use- rate analysis suggests that the increased clearing of pine was primarily caused by demands for domestic fuel wood by an expanding urban population. This forest mismanagement is directly linked to accelerated erosion rates which are considered primary elements in the collapse of the Maya state.

Conclusively, it's important to state emphatically the difference between agents of deforestation and its cause to have a clearer perspective of their.
The United States Environmental Protection Agency defines deforestation as the "permanent removal of standing forests. Deforestation is the clearing, destroying, or otherwise removal of trees through deliberate, natural, or accidental means. It can occur in any area densely populated by trees and other plant life, but the majority of it is currently happening in the Amazon rainforest. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people. It was only after the onset of the modern era that it became an epidemic.

As one of countries which has the large tropical forests in the world and the largest in ASEAN, Indonesia has been facing serious deforestation problems. This study tries to extend and explore the causes of deforestation in Central Kalimantan, one of Provinces in Indonesia which has been facing the highest deforestation problem caused by many factors.
People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. Direct causes of deforestation are agricultural expansion, wood extraction e. Rarely is there a single direct cause for deforestation. Most often, multiple processes work simultaneously or sequentially to cause deforestation. The single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs.
Deforestation , clearance , clearcutting , or clearing is the removal of a forest or stand of trees from land that is then converted to non-forest use. The most concentrated deforestation occurs in tropical rainforests. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses regardless of whether it is human-induced.

Сегодня у меня было ужасное утро. Вчера вечером я скачал файл Танкадо и провел у принтера несколько часов, ожидая, когда ТРАНСТЕКСТ его расколет. На рассвете я усмирил свою гордыню и позвонил директору - и, уверяю тебя, это был бы тот еще разговорчик. Доброе утро, сэр. Извините, что пришлось вас разбудить.
Что?! - хором вскричали Бринкерхофф и Фонтейн. - Он пытался, сэр! - Мидж помахала листком бумаги. - Уже четыре раза. ТРАНСТЕКСТ заклинило. Фонтейн повернулся к окну. - Господи Исусе.
Все в комнате дружно повернули головы. Диаграмма чем-то напоминала бычий глаз. В центре находился красный кружок с надписью БАЗА, вокруг которого располагались пять концентрических окружностей разной толщины и разного цвета. Внешняя окружность была затуманена и казалась почти прозрачной.
