THE STUDY OF INFLUENCE ON SUPPLY AND DEMAND OF WOOD AND CARBON STOCK CHANGING WOODEN HOUSE LIFE - CASE STUDY FOR WAKAYAMA PREFECTURE USING GEOGRAPHICAL INFORMATION -

Abstract

 The study evaluated the influence of supply and demand of residential wood on the amounts of carbon fixation and CO₂ absorption by forests. The residential wood occupies most of all wood demand. The result of the analysis revealed that both the amounts of carbon fixation in the forest and the residence decreased. Moreover, it was clarified that the wood utilization for long-lived houses made the amounts of carbon fixation in the forests and residences the maximum. On the other hand, the amounts of CO₂ absorption by the man-made forest would decrease in the future. However, the study showed the possibility of the increase in CO₂ absorption admitted in the Kyoto Protocol.
