Forests to attract rain[ edit ] Several new studies suggest that forests attract rain and this may explain why drought is occurring more frequently in parts of the world such as western Africa. Together these may lead to desertification and the loss of topsoil ; without soil, forests cannot grow until the long process of soil creation has been completed - if erosion allows this. Trees help to maintain the water cycle and give shelter to the organisms. If done with proper planning and at appropriate sites, it can become a commercially viable solution for many human needs without harming the balance of nature. The fire caused, by man or nature, results in huge loss of forest cover. Other factors include overgrazing by livestock , especially animals such as goats , cows , and over-harvesting of forest resources. A new study by Carol Rasmussen, NASA's Jet Propulsion Laboratory gives the first observational evidence that the southern Amazon rain forest triggers its own rainy season using water vapor from plant leaves. The European Union EU has paid farmers for afforestation since , offering grants to turn farmland back into forest and payments for the management of forest. In an afforestation hotspot outlined in Para, Brazil, 1 billion trees are intended to be planted to restore deforested lands by The process of planting trees in empty lands helps promote the fast propagation of specific types of trees for the wood industry. Owing to the sensitivity to over usage and slow growths, these forests cannot be used continuously for commercial purposes like wood products. Millions of plants and animal species are on the verge of extinction due to deforestation.
The projects range from large habitat restoration projects to local biodiversity projects. Furthermore, the Maharashtra government planted almost 20, saplings in the entire state, and will pledge to plant another 30, next year.
Hong Kong[ edit ] Since the founding of the crown colony in the 19th century, afforestation has taken place to prevent soil erosion in the catchment areas of the reservoirs that were built.

Forest Fires We lose a large number of trees each year due to fires in the forest in various portions worldwide. Floods Deforestation leads to land erosion because the trees maintain the surface of the mountains. Wood is used as fuel most commonly and so large amount of trees are cut down for fuel supplies. Owing to the sensitivity to over usage and slow growths, these forests cannot be used continuously for commercial purposes like wood products. Large amounts of soil wash into local streams and rivers and cause damage to hydroelectric structures and irrigation infrastructure. Current Efforts In the central hardwood forest region of the US, increasing numbers of land owners are converting crop land marginally into a forest. Forest wood has been an essential need for us since the time of civilization and still continues to be the main source for many uses in our day to day life. We lose about 50 to species of animals each day due to the destruction of their habitats. Soil Erosion Cutting down on trees leads to clearance of forests and so soil erosion occurs. Forest Restoration Logging, urban sprawl and agriculture all demand the cutting down of trees to make way for development or economic growth. Increasing population directly affects forest as with the expansion of cities there is a need for more land for housing and settlements.
Forest Restoration Logging, urban sprawl and agriculture all demand the cutting down of trees to make way for development or economic growth. Question For You 1.
Between andEU afforestation policies made possible the re-forestation of over 5, square kilometres of land. Agricultural Activities The conversion of forests into agricultural land is a big reason for deforestation.
We lose about 50 to species of animals each day due to the destruction of their habitats.

Conclusion Afforesting is a positive effort in curbing the over-use and destruction of natural forests. Thousands of Adelaide citizens have participated in community planting days. Biodiversity Losses Deforestation alters land and so that many of the plants and animals do not survive. Spain today has the fifth largest forest area in the European Union. As a result, China has the highest afforestation rate of any country or region in the world, with 47, square kilometers of afforestation in Sometimes special tools, such as a tree planting bar , are used to make planting of trees easier and faster. Forest Restoration Logging, urban sprawl and agriculture all demand the cutting down of trees to make way for development or economic growth. Afforestation in Previously Unforested Areas Forests help make semiarid lands more sustainable by protecting bare ground from soil erosion, and help to lock in soil moisture. By , more than hectares will be added to the plan. There should be an implementation of regulations of laws at organizational and governmental levels due to the extent of deforestation. In around Most of the trees were cut down and extensive reafforestation was carried out after the war. Firewood and charcoal are used as fuel. Timber Production One of the primary cause of deforestation is the production of timber.
The term should not be confused with reforestation, which is the process of specifically planting native trees into a forest that has decreasing numbers of trees.
