The main pressures from human activities include agriculture expansion, transport infrastructure development, unsustainable forestry, air pollution and intentional burning of forests. Many forest resources are threatened by degradation, fragmentation and conversion to other types of land uses. This includes avoiding overexploitation and degradation, so as to maintain adequate supply of wood for production activities, and to ensure the provision of essential environmental services, including biodiversity and carbon sinks. A new UNFCCC mechanism, Reducing Emissions from Deforestation and Degradation (REDD) in developing countries, will help mobilise finance to mitigate deforestation and thus GHG emissions.
