Consequences of deforestationDeforestation is one of the causes of environmental contamination, the phenomenon of the Earth warming, famine, floods, elephants put Woods on the village merchant killed people, destruction of property ... as well as ruin the forest products under the forest canopy causing the serious ecological imbalance , leading to the erratic climate change, hurricanes, flash floods, landslides and several types of disease.Worldwide, deforestation causing damage to 45 billion USD/year. According to the latest statistics of the Ministry of the environment, American per year on average in the world have about 33 million ha of forest lost for many different purposes has created more than 1.5 billion tons of CO2 into the environment, takes up to 20% of the man-made emissions causing greenhouse effect the Earth's temperature heats up.It is estimated that with the current deforestation to 2050, up to two billion people, i.e. 20% of the world's population will suffer from water shortages. Most people suffer this lack of water scene live in developing countries. There's also food sources at risk threatened by the water used for irrigation is also becoming scarce.The harmful effects of deforestation in watershed VNAccording to the latest report of the World Food Programme (FAO), VIETNAM is one of the five countries most heavily influenced from the disaster, especially rain storms and floods. Rain storms occur on the territory of VIETNAM is increasing both in frequency and the harmful, are becoming real threats to human life and the development of the economy.Besides the causes such as geographic features, climate change causing floods situation in VIETNAM is becoming more fierce, also a direct cause of human. Watershed deforestation to timber extraction, agriculture, hydroelectric development ... do the vegetation on the basin more lead to the ability to stop the flow, flood the focus more quickly.Mid-October, much of the region has occurred on many successive flood rains caused heavy damage on people and of. Rain flood this time are the functional sector reviews is a new year and draw conclusions, is the source of deforestation by accident. When Woods drained were chopping, the intensity of the floods go fast, make the water level rise very quickly. Trees prevent flooding disasters. When flood waters rise high, forest tree roots and water power will drag-part would flood water. There are forest tree, power support, more powerful wind-forest trees and weaken the power in the storm passing through. According to the scientists, the more watershed forest area and forest protective in the central province were leveled in favour of hydraulic power is lost the ability to regulate upstream water when heavy rain, this is a main cause of flooding on more seriously.Our country is actively done 2 great program that is national target programs to deal with climate change and the national program on the prevention of natural disasters. The objective at the heart of this program which is planting and forest protection. From the model made until reaching the result is still a distant and unknown to this new gap ever narrows, to avoid risks for themselves and future generations.

The consequences of deforestation
Deforestation is one of the causes of environmental pollution, earth phenomena warming, famine, floods, accidents leave the forest elephant villages killing people, breaking Property damage ... as well as destroying the forest products under the forest canopy caused ecological imbalance serious, leading to erratic climate change, floods, flash floods, landslides and incurred more 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.
