DeforestationDeforestation is the conversion of forested areas is the conversion of forested areas to non-forestedto non-forested
Generally this removal or destruction of significant Generally this removal or destruction of significant areas of forest cover has resulted in a degraded areas of forest cover has resulted in a degraded environment with reduced biodiversityenvironment with reduced biodiversity

BackgroundBackground
Deforestation has been practiced by Deforestation has been practiced by humans for thousands of years. humans for thousands of years.
Fire was first tool that allowed Fire was first tool that allowed humans to modify the landscapehumans to modify the landscape
Deforestation correlated with the Deforestation correlated with the agricultural revolution as space is agricultural revolution as space is needed for crops (8-10 thousand needed for crops (8-10 thousand years ago)years ago)
RationaleRationale
Growing worldwide demand for woodGrowing worldwide demand for wood Forest used for fire wood or in Forest used for fire wood or in
construction, paper and furniture construction, paper and furniture Clearing land for commercial and Clearing land for commercial and
industrial development (including road industrial development (including road construction) construction)
Growth of Local Populations in rural Growth of Local Populations in rural areas increases demand for areas increases demand for agricultural space and wood fuelagricultural space and wood fuel

Under the Kyoto Protocol countries that exceed Under the Kyoto Protocol countries that exceed their targeted cuts in GHG emissions or are their targeted cuts in GHG emissions or are producing less than the required limit, will be able producing less than the required limit, will be able to sell emission-reduction credits to those unable to sell emission-reduction credits to those unable to meet their targetsto meet their targets

Countries will loose substantial economic Countries will loose substantial economic revenuesrevenues
Compensated ReductionCompensated Reduction Countries that elect to reduce national
level deforestation to below a 1980-1990 level would receive post facto compensation
This will create large scale incentive to commit to stabilization and further reduction of deforestation in the future
This will also facilitate significant developing country participation in the Kyoto Protocol Framework
