Forests play a vital role in the social, economic, and environmental development of any country. Paper, composed principally of wood fiber, is an essential commodity in promoting literacy, communication, documentation, and packaging. However, there is much concern about the world's forests being over-utilized. This has led to serious repercussions, not only to humanity, but also to the earth's biodiversity as a whole. It is now time that forests be used in a more responsible and ethical manner. Because of reduced forest area, increasing pulpwood costs, and an increasing demand for pulp and paper products, it might be expected that the focus would shift to high yield pulping processes or to the use of cellulosic non-wood raw materials. Non-woods are available in good supply all over the world, but are currently under-utilized. It is estimated that replacing 5–10% of wood pulp with non-wood pulp would have an important impact on the conservation of forests and the environment. This replacement of wood pulp by non-wood pulp could be environmentally and economically acceptable even in developed countries. By doing so, pulp and paper mills would have a lead role in reducing their dependency on forests for fiber. This determination and commitment would enhance the long-term sustainability of forests and the pulp and paper industry. Above all, it would be a sustainable step towards "our common future." Key words: forest, sustainable development, fiber supply, pulp and paper, non-woods

Fiber morphology of 3 species of bamboo namely Bambusa vulgaris, Gigantochloa levis, and Gigantochloa scortechinii at age of 1, 3, and 5 years, was evaluated. It shows that different species of bamboo have different properties in terms of their fiber morphology that consist of fiber length, fiber diameter, and lumen diameter. Fiber diameter, fiber length, and cell wall thickness increased with the increasing of the bamboo age but the lumen diameter decreased when the bamboo gets older. G. levis at age 1 to 3 and G. scortechinii at age 1 have high potential to be the raw materials for the pulp and paper industry.
