As experts says, deforestation is estimated to be responsible for around 20 percent of all human-induced CO2 emissions. Most of this effect being happen in tropical forest. However this figure is highly uncertain. According to 2007 GTZ report, the reasons are:
- There is a notorious lack in reliable forest inventories.
- the ascertainment of deforestation depends on the diverging definitions of forests
- Greenhouse gas emissions from forest degradation (i.e. vegetation loss inside a standing forest) are difficult to estimate, and there is no single accepted definition of it Re-growth after deforestation
- N2O and CH4 emissions due to forest fires have not yet been quantified on a global scale, but they contribute in a significant way to the increase in greenhouse gases in the atmosphere.
What do you think? Should we give priority to avoiding deforestation?
