Past severe deforestation and over-exploitation of forest resources experienced by many countries have led to the need for accurate information on the state, growth and harvesting of forests which, in turn, led to the implementation of forest inventory systems. In the eighteenth century, the sustainability concept emerged, and regular forest management featuring Standwise Forest Inventory (SFI) was established for the primary purpose of ensuring adequate wood production. Unlike SFIs, National Forest Inventories (NFI) use systematic sampling designs which enable use of unbiased estimators and uncertainty measures. Forest inventory has been the base for national and international reporting, and data from both SFIs and NFIs are used as input to projections systems. Therefore, the accuracy of inventory data influences the reliability of future wood availability projections. Recent developments in the bioenergy and bio-economy sectors are expected to lead to continuous increases in biomass consumption and will require additional and more comprehensive projection studies to support policy makers. This chapter presents an overview of the current state of European and North American forests and forest resources and a brief summary of the wood consumption trends for both continents. Some background information is also presented for the two different kinds of forest inventories whose data are used in future projections. Finally, the book structure is also presented.
