Book excerpt: The xylem anatomy of 28 species of commercially and potentially commercial timbers of West Africa is described together with information pertaining to seasoning qualities, durability and working properties, as well as the uses of wood. A comprehensive discussion on the mechanical properites, establishing the methodologies for evaluating the potential utilization of these woods, has been included. Shrinkage and swelling in wood have always presented problems in the utilization of woods. A discussion relating to the differences among (a) moisture content change and shrinkage, (b) the effect of drying conditions on shrinkage and (c) the variation in shrinkage in different species is presented. To aid both beginning students and to refresh the minds of practicing wood technologists, a glossary of the principal terms used in describing the minute features of timbers has also been added.

Download or read book The Dry Forests and Woodlands of Africa written by Emmanuel N. Chidumayo and published by Routledge. This book was released on 2010-09-23 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dry forests and woodlands of Sub-Saharan Africa are major ecosystems, with a broad range of strong economic and cultural incentives for keeping them intact. However, few people are aware of their importance, compared to tropical rainforests, despite them being home to more than half of the continent's population. This unique book brings together scientific knowledge on this topic from East, West, and Southern Africa and describes the relationships between forests, woodlands, people and their livelihoods. Dry forest is defined as vegetation dominated by woody plants, primarily trees, the canopy of which covers more than 10 per cent of the ground surface, occurring in climates with a dry season of three months or more. This broad definition - wider than those used by many authors - incorporates vegetation types commonly termed woodland, shrubland, thicket, savanna, wooded grassland, as well as dry forest in its strict sense. The book provides a comparative analysis of management experiences from the different geographic regions, emphasizing the need to balance the utilization of dry forests and woodland products between current and future human needs. Further, the book explores the techniques and strategies that can be deployed to improve the management of African dry forests and woodlands for the benefit of all, but more importantly, the communities that live off these vegetation formations. Thus, the book lays a foundation for improving the management of dry forests and woodlands for the wide range of products and services they provide.

Available in PDF, EPUB and Kindle. Book excerpt: SUSTAINABLE USE of Wood in Construction Sustainable Use of Wood in Construction There is a great deal of innovation in the use of wood in construction, from impressive modern buildings to new construction products that reduce build times and improve building performance. As a renewable resource with proven low embodied energy, wood is both an environmentally responsible and a highly practical choice as a construction material. However, forest management practices vary throughout the world: some are highly effective in delivering a sustainable, long term supply of timber; whereas others are less so, and could result in forest depletion and significant environmental degradation. Against this background, a number of certification schemes have been developed that seek to ensure that all timber is harvested from sources that are at least legally-sourced, and at best, sustainably managed. Sustainable Use of Wood in Construction explains how and why wood may be grown sustainably, and how this versatile material can be specified and – most importantly – sourced, for use in the construction industry. It explains the modern regulatory framework within Europe that seeks to eliminate the use of illegally-harvested wood, and it shows how to ensure that everyone who sells or uses wood for construction is following the rules. Finally, the book explains how, at the end of its first use in construction, wood can be recycled, by reprocessing into another wood-based construction material, or by using it as biomass.

Book excerpt: Nowhere eise in the world did industrialized countries leave such early marks in the rainforest as in West Africa. Past and present developments here are in one way or the other significant for rainforests on other continents as weil. West Africa is a pioneer in both a good and a bad sense. This is reason enough to take a closer Iook at the history of moist tropical West Africa. Until recently, no one really seemed to be interested in the rainforests except for a few specialists. The world's scientific community neglected to study the incalculable riches of tropical forests, to make the public aware of them and their due importance. Although interdisciplinary research has been a popular topic for some decades now, it was not applied to just the most complex habitat on earth. Scientists from all fields studied only that which was easiest to record, seemingly blind to a myriad of details awaiting closer examination. Botanists wentabout establishing their herbariums and paid much too little attention to the vegetation as a whole, or to the significance of useful plants for local populations. Zoologists, too, busied themselves with collecting and describing species. Anthropologists, on the other hand, tended to overlook faunal details: in their ignorance of the animal world, they wrote of tigers and deer in Africa. And finally, foresters saw neither the forest nor the trees for the timber - and even confused rainforests with monocultures of fir trees.

This book was released on 2011-11-03 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work builds on the results of the COMPETE Bioenergy Competence Platform for Africa, which was supported by the European Commission and coordinated by WIP Renewable Energies, Germany. The five sections cover biomass production and use, biomass technologies and markets in Africa, biomass policies, sustainability, and financial and socio-economic issues. This valuable work is, in effect, a single-source treatment of a key energy sector in a part of the world which still has a lot of unrealised potential for development.
