We need incentives to curb deforestation and climate change
The disappearance of forests annually generates two billion tons of carbon
December 9 2005, Rome - Noting that deforestation accounts 25 percent of all emissions of carbon dioxide (CO2), a greenhouse gas caused by human activities, FAO offered today to provide data and technical advice to countries attending the UN Conference on climate change held in Montreal, to explore ways to create financial attractions for reducing forest loss in the developing world.
"The latest FAO data on the role of forests in mitigating climate change in our recent Forest Resources Assessment of the World (FRA 2005) clearly illustrate the contribution of forests to the fight against global warming - and the problem is aggravated by deforestation, "said Dieter Schoene of the FAO Forestry Department.
"There are a number of strategies that countries can use to monitor deforestation reductions and increased carbon storage closely, especially in tropical countries where forests are essential for removing carbon dioxide from the environment. atmosphere, "he added. This accounting would be crucial for any program to create financial incentives for carbon storage in developing countries.
Two billion tonnes of carbon every year due to deforestation
According to the FRA 2005 report, the world's forests are a 283 tank gigatonnes (Gt) of carbon would do in their biomass, while the total carbon stored in forest biomass, deadwood, litter and soil together is roughly 50 percent to the amount present in the atmosphere, or a trillion tons.
But the assessment also shows that the destruction of forests adds almost 2 billion tons of carbon to the atmosphere each year.
"It is important to prevent this stored carbon from escaping to maintain the carbon footprint. It's vital for the sake of the environment, "says Schoene.
For the whole of the planet, carbon stocks in forest biomass decreased at least 1,1 Gt annually during the period 2000-2005, because of deforestation and forest degradation, the assessment found. Carbon in forest biomass decreased in Africa, Asia and South America during the 1990-2005 period, but increased in all other regions.
These losses were partly offset by forest expansion (including planting) and an increase in growing stock per hectare in some areas.
Better use of forests in the fight against climate change
It would not only prevent the conversion of forests to other land uses, but also create new carbon stocks by forest expansion (new plantings) and reforestation (replanting of deforested areas), FAO said.
Carbon stocks in forest biomass are the highest per hectare in West and Central Africa, and Central and South America, according to the FRA 2005.
Particularly in the tropics, where vegetation growth is very fast - which speeds up the absorption of carbon from the atmosphere - the planting of trees can absorb large amounts of CO2 in a relatively short time. In these areas, forests, with their biomass and their wood may set up 15 tonnes of carbon per hectare per year.
FAO and other experts have estimated that global carbon retention resulting from reduced deforestation, increased regrowth of forests and an increase of agroforestry and plantations could make about 15 percent carbon emissions from fossil fuels over the next 50 years.
