Ng RECOMMENDATIONS OF THE 381 THIRD INTERNATIONAL BAMBOO WORKSHOP REPORT OF THE MEETING OF THE 383 SUB-GROUP ON “BUILDING AND ENGINEERING WITH BAMBOO” PARTICIPANTS IN THE THIRD INTERNATIONAL BAMBOO WORKSHOP 384 vii FOREWORD By far the single-most important item of forest produce used by rural communities of the tropics, from the cradle to the coffin, is the bamboo. Over 75 genera and 1250 species are reported to occur in the world. Of late, the demand for this material has increased far beyond the availability, causing serious problems of over-exploita- tion and depletion of resources. Bamboos are aptly called the “poor man’s timber”. They are particularly important for the people of the East where they are found in greatest abundance and variety. Their strength, straightness, light- ness combined with extra-ordinary hardness, range in size, abun- dance, easy propagation, and the short period in which they attain maturity, make them suitable for a variety of purposes and hundreds of different uses have been reported from times immemorial. Even today, the bamboo continues to find new uses, such as paper-making, rayon industry, construction, architecture, engineering, technology, handicrafts, food and medicine. No doubt, this amazing tree-grass has played a significant role in the life and activities of man and perhaps no growing thing on earth has so many and as varied uses as the bamboo. Yet, we know very little about several aspects of this fascinating plant and these are receiving a high priority in the research activities of bamboo specialists. Thus, its biology, embryology, cytology, physiology of flowering, ecology, silviculture, utilisation are all under detailed investigation. Even the authentic identification of the different species of bamboos which is basic to all other studies has to be undertaken with a sense of purpose. It is in this context that the third International Bamboo Workshop held at Cochin, is specially relevant. The workshop gave an oppor- tunity for specialists in different aspects of bamboo to come together, discuss various problems under the same roof, evaluate the present state of knowledge on this very important resource and suggest measures for its effective propagation, scientific conservation, proper utilisation and management. To a true scientist and scholar, work is its own reward. Workshops of this type facilitate exchange of ideas and provide an entirely new dimension in the pursuit of truth and knowledge. The deliberations of the workshop have furthered our knowledge on the subject and the papers contained in this volume will add to the information of all those who are interested in the different aspects of this wonderful grass.
