Abstract: | Our world is largely dependent upon the forestry productions. Through the exploitation of forest reserves, we manufacture
various industrial products, furniture, and obtain fuel and energy. Forestry productions should be conducted without large-scale
deforestation and environmental degradation. In present study we perform a review and forecast analysis on forestry productions
worldwide, with the objectives of providing an insight into the trend for several types of forestry productions in the future,
and providing referential data for sustainable forestry productions and environmental management. Polynomial functions are
used to fit trajectories of forestry productions since 1961 and forecasts during the coming 20 years are given in detail.
If the past pattern continues, world fibreboard production would dramatically grow and reach 224,300,000 ± 44,400,000 m3 by the year 2020, an increase up to 240.7 to 408.9% as compared to the present level. Roundwood production of the world would
change by −55.5 to 70.4% and reach 3,526,600,000 ± 2,066,800,000 m3 by 2020. In 2020 world production of sawlogs and veneer logs would change by −100 to 164.6% and reach 1,212,900,000 ± 1,242,600,000 m3. Global wood fuel production would change by −68.9 to 1.4% and reach 1,130,900,000 ± 600,800,000 m3 by 2020. Forestry productions in developed countries would largely surpass productions in developing countries in the near
future. World forestry production grew since 1961 excluding wood fuel. Roundwood and wood fuel account for the critical proportions
in the forestry productions. Wood fuel production has being declined and rapid growing of roundwood production has slowed
in recent years. Widespread use of regenerative wood substitutes and worldwide afforestation against deforestation will be
among the most effective ways to reduce deforestation and environment degradation associated with forestry productions. |
