Recent years, deforestation becomes one of the most serious problems affected all countries. Sustainable forestry and woodland management allow the promotion of small-scale social forestry programs, where local communities are involved in the establishment of tree nurseries…
Also, the reasons for deforestation are largely economic. Softwoods from areas under boreal forest are used in the paper and construction industries, while tropical hardwoods are used in the manufacture of furniture and for construction purposes. In South American countries, forest and woodland areas are also heavily exploited for wood-fuel, which is the main source of energy. Following Ehrhardt-Martinez (1998):
"Deforestation in developed countries has reached very low levels, it accounts for the loss of 16.3 million hectares of forest per year in developing countries -- an area approximately twice the size of Portugal. An estimated 15.4 million hectares of forest loss occurs each year in tropical regions, with the worst losses occurring in Latin America and the Caribbean (7.4 million ha) (568)
Clearly, the exploitative decline in forest and woodland resources is not sustainable in the long term and a number of environmental problems, including soil erosion and biodiversity losses, have developed as a result. Improved road access into deforested areas is likely to encourage population influx and increased shifting cultivation (Margulis 39).
Farmers are then encouraged to trans...
These strategies are very successful helping to establish a special culture of forest management and land use (Ehrhardt-Martinez, 569). For the highlands, this meant more emphasis on cattle-ranching, generating meat and dairy products for the growing urban markets, and less importance for traditional subsistence crops like corn, wheat and barley. The establishment of all-weather routes meant that areas which had only been accessible during the dry season could now be used for continuous product extraction, promoting permanent settlement which in turn also increased the demand for local food products. it should be noted that forests, while not the only, are still the main source of 'reserve land areas' to be gradually included in the pool of cultivated areas (WRM 1998). Due to the low commercial scale of remaining valuable timber species, it is usually not worthwhile to open a new road in a mountainous region just for the sake of timber extraction; this thus eliminates any prospective 'indirect' impact. The extraction of logs here may rather be a by-product of forest-clearing implemented for general purposes of colonization (Margulis 89). According to road distance and market requirements, either all types of firewood are cut and used across the board for conversion, or hard species with a high energy content are selected. In the case of across-the-board utilization, charcoal-burning would indeed be a candidate as a cause of deforestation, provided that the once-and-for-all rent from clearing and charcoal conversion is in fact the decisive motivation within the landowner's resource-use strategy.
The problem of deforestation needs complex solutions and ...

The natural environment of the world is in a state of rapid transition. The changing environmental conditions have brought about rapid changes in the climatic patterns in the context of global geography and climatology. Climate change has turned into a global phenomenon affecting human civilizations from time immemorial.
However, going by the statistics, Brazilian government has made a significant move aimed at preserving Amazon. Firstly, the Brazilian has created national parks within the forest to ensure that the forest is protected and conserve. The government has also enacted laws aimed at protecting the forest.
There are various reasons behind this high rate of deforestation in this area. One of these causes is human activities. According to Coe, Costa and Soares-Filho, Global economic and regional population and development pressures have resulted in high rates of deforestation in the Amazon River basin. Primary economic activities include cattle ranching, soy bean and other cash crops production.
The paper is divided into three parts where the first part deals with introducing both the issues. The second part concentrates on critically examining whether there is a relation between the two issues and the third part draws conclusion from the facts and evidences from previous section.
The author states that South America lost the most number of hectares to deforestation. From 1990 – 2000, the region has lost more than 3,500 hectares per year. Deforestation slowed down between 2000 – 2005. This meant that population has grown and urbanization has sped the deforestation. Asian region suffers 2,500 hectares deforested per year.
Other countries such as Colombia, Peru and Venezuela have some parts of the forest. The Amazon is home to many species of animals and plants.
According to Barbosa, more than 300,000 square miles of land in the Amazon rainforest has been destroyed over the last four decades.
Soil carbon storage is an essential component of the global carbon cycling. Mainly, they do have high carbon content and are vulnerable to erosion because of agricultural deforestation. The use of land, particularly annual cropping, has affected the carbon levels in the soil.
The author analyzes several negative impacts caused by deforestation: the ultimate decrease in biodiversity due to loss of habitats of many species, the increase in emissions of carbon dioxide and other greenhouse gases, the increasing greenhouse effect, shift of forest water cycle due to loss of forest canopy, and the rapid rise in temperature.
