Abstract
Wood absorbs and fixes the CO2 from atmosphere in its growth process and suppresses increasing of CO2. Utilization of wood for structures in long-term increases the fixed effect for CO2 further, and it contributes to global warming control. When the thinned wood is used for erosion control structures, the forest thinning will be promoted, the forest improvement advances, and CO2 absorption amount of forest increases. There are thus many benefits to use wood for erosion control structures. However utilization of wood for erosion control structures is limited in the present state of affairs. Challenges to use wood for erosion control structures with summarized recent research progress situation and wood use of future prospects are described.
