Challenges and researches for the future
Plantation projects are required to make the maximum use of limited land; therefore, we must find the answers to an important question: "Which tree species should be planted?"
The appropriate tree species for plantation in the pulp and paper industry are Eucalyptus and Acacia which have the advantages of fast initial growth and rich fiber contents. The particular individual trees which growth is most suited to the climate and soil of a site would be selected, and seeds and cuttings of the selected trees are used to create high-quality forests. Research is underway into tissue culture technology for mass-producing the superior seedlings.
Making paper requires cellulose. Research is being conducted in biotechnology to improve the breed with high fiber content and to suppress the formation of a non-fiber substance, lignin.
A potential occurrence of blight and harmful insects can be anticipated in plantation from nursery to harvest. The improvement of breed that are more capable of resisting disease and insect damage, drought, cold and acid soil would make plantation possible on wider variety of lands in the world.
Each plantation site has its own conditions in nature and local communities. This means that each project should be operated to achieve success by careful management. After a plantation project is launched, the system for monitoring the site and its vicinity is instituted, and long-term field surveys and research are simultaneously conducted to determine the best approaches to work, fertilization and soil fertility maintenance on the site in order to create the best possible forest.
