Descripción
The world’s forests provide vital economic, social and environmental benefits. They supply wood and non-wood forest products, support human livelihoods, supply clean water and provide habitat for half the species on the planet. However, approximately 13 million hectares of forest are converted to other land uses annually worldwide. This forest clearing along with other forestry related activities is responsible for about 17 percent of human induced greenhouse gas emissions. International process es related to forests demand accurate information on tree cover and forest resources. Since 1946, the Food and Agriculture Organization of the United Nations (FAO) provides detailed information on the world’s forests, their extent, their condition and uses at 5 to 10 year intervals. For the Global Forest Resources Assessment 2010 (FRA 2010), a systematic, comprehensive, global survey of forests based on remote sensing imagery is being undertaken.
