Not only in VN but worldwide, forest resources is increasingly shrunk in size since been devastated. Shrinking forests entails huge risks in nature as distort global ecosystems, increases the risk of water scarcity, climate change and increased natural disasters ...
The coverage of VN forest in less than 40%
According to the MARD, the country currently has a total forest area of 13,118,773 hectares, of which 10,348,591 ha of natural forests and plantations that are 2,770,182 hectares. Among them, more than half of our country's natural forests under poor or regenerating forests, whereas forest canopy jungle and closed accounts for over 9%.
The latest statistics of the FPD, the year-to-month 9/2010 1553.68 hectares of forest have been cut down and burnt 5364.85 hectares. Natural forest area of our country is in decline with dizzying speed and forest cover in the central region has been severely reduced. Currently, forest cover to less than 40%, of which primary forest area is only 10%. This is a very serious problem, because due to climate change, in the future, central VN general and in particular will continue to suffer from the disaster caused by the weather phenomenon El Nino extreme, La Nina caused more frequent and intense.
The consequences of deforestation
Deforestation is one of the causes of environmental pollution, earth phenomena warming, famine, floods , victims give forest elephants in villages killing people, destroying property ... as well as destroying the forest products under the forest canopy caused ecological imbalance serious, leading to climate change Furniture Typically, floods, flash floods, landslides and generated many diseases.
Worldwide, deforestation caused losses to $ 45 billion / year. According to the latest statistics of the Ministry of Environment America, each year on average in the world have about 33 million hectares of forests are destroyed for many different purposes, has created more than 1.5 billion tons of CO2 into the environment, accounting for up to 20% of man-made emissions of greenhouse effect causing global warming temperature.
It is estimated to deforestation today, by 2050, up to two billion people, or 20% of the world population will dehydration. Most people suffer from water shortages live in developing countries. Besides food sources are at risk threatened by water for irrigation becomes scarce.
The impact of deforestation upstream in VN
According to the latest report of the World Food Programme (FAO), VN is one of five countries most heavily affected from natural disasters, especially rainstorms and floods. The rainstorm occurred in the territory VN increase both the frequency and the danger, is becoming real threat to the lives of people and the development of the economy.
In addition to these causes as geographical features, climate change causes flooding situation in VN is becoming more intense, there is a direct cause of human. Watershed Deforestation for logging, agricultural development, hydropower ... do vegetation in the basin are decreasing leading to potentially poor clearance flow, flood focus faster.
In mid-October last several provinces in central occurred several consecutive days of rain caused floods and heavy losses of life and property. This was the first flood branches evaluation function is activated one hundred years and conclude, is due to deforestation upstream. When headwater forests are cut down, the intensity of flooding going fast, making very fast rising water. Trees prevent floods, erratic disaster. When floodwaters rise, forest clearance and water power plant roots will absorb flood waters somewhat. There are trees, water power stronger support, forest trees and weakening wind power in the storm passing through the area. According to scientists, the many watershed forests and protection forests in the central region were razed to make room for hydropower are losing the ability to regulate water when heavy rains upstream, this is a major cause causing severe flooding more days.
Our country is actively implementing two major programs such as the National Target Programme to Respond to Climate Change and National Programme for Disaster Prevention. The central goal of this program that is growing and forest protection. From implementation model until results are still a distant and unknown to ever new narrow this gap, to avoid danger to themselves and future generations.
