Book Description
Forest degradation as a result of logging, shifting cultivation, agriculture and urban development is a major issue throughout the tropics. It leads to loss in soil fertility, water resources and biodiversity, as well as contributes to climate change. Efforts are therefore required to try to minimize further degradation and restore tropical forests in a sustainable way. This is the first research-based book to examine this problem in East Africa. The specific focus is on the forests of Ethiopia, Tanzania and Uganda, but the lessons learned are shown to be applicable to neighbouring countries and others in the tropics. A wide range of forest types are covered, from dry Miombo forest and afromontane forests, to forest-savannah mosaics and wet forest types. Current management practices are assessed and examples of good practice presented. The role of local people is also emphasized. The authors describe improved management and restoration through silviculture, plantation forestry and agroforestry, leading to improvements in timber production, biodiversity conservation and the livelihoods of local people.

Book Description
Forest ecology includes within its scope the components and functions of forest ecosystems -- a community of organisms interacting with each other and with their physical environment. Forest ecosystems, which consist of bacteria, plants, birds, mammals, reptiles, amphibians, soil, water and air, differ from other ecosystems in that they are dominated by trees and other woody vegetation. Each of these components plays an important role in the function and health of the forest. This book presents important research in the field.

Book Description
This book - Biodiversity Enrichment in a Diverse World - considered biodiversity (plants, animals, fungi, and microbes) from three different angles: genetics, species, and ecosystems. The relationships between them are complex and it looks at these aspects from different angles and also various interventions at different levels. The scientific approach of the book demonstrates that the three levels are closely inter-connected and action is therefore needed to conserve and protect the systems if the benefits provided to human life will continue to be available. However, conservation of the biological diversity is essentially an umbrella term for traditional species, relationship to human health, ecosystem conservation and the need to manage the human use of the species and ecosystems in a sustainable way.

Book Description
Planted forests - despite being only seven per cent of the world's forest resources, have superseded naturally regenerating forests as the principal source of industrial wood products. Lessening the pressure for wood production, on natural forests, tree planting has released them to be managed for other purposes - carbon sinks, soil and water protection, conservation of biological diversity, recreation and amenity. Representing a complement, but not an alternative, to natural forests, planted forests have become increasingly important for reducing worldwide deforestation, loss of forest ecosystems and forest degradation. Examining the significance of this rapidly emerging world resource, chapters consider the strengths and weaknesses of planted forests, management objectives for their use and aspects of ownership and policy. Data from key production countries are used to evaluate the implications and sustainability of planted forests as a source of forest products as well as social and ecological issues.

Book Description
Face to the current global energy crisis, there is an urgent necessity of searching for alternatives to fossil fuels, and this book shows how timber is a promising resource for sustainable energy production. Northeast Mexico represents an important forest resource to satisfy the needs of the population in these areas. In order to harness these forest resources, technology for exploring these valuable resources must be developed. These technologies (with special reference to biology and wood technologies) are available in scattered form in a few books but there is no central, comprehensive source for practical forest scientists for adopting efficient forest management, practice, and exploration. This book deals with the characterization of the vegetation, morphology, phenological development, biomass production (leaf, litter, wood), and bioenergy of some timber-yielding species of Northeast Mexico, which will serve as a guide to study timber-yielding plants in the native vegetation of Tamaulipan thornscrub and experimental plantations. This includes morphology, vegetation cover, biomass production in terms of volume leaf biomass, litter, and volume of fire wood and timber. Special emphasis is given to the estimation of bioenergy products and chemical composition (Ph, extractable lignin, and inorganic elements). Large variations exist in vegetation cover, morphology, phenological development, biomass production of leaf and litter, volume of wood and various variable of bioenergy products among the selected species. The maximum production was found in summer and the volume of the harvestable timber was obtained in experimental plantations. This book, therefore, will serve as a practical handbook to characterize timber-yielding plants, which will help to efficiently manage forestry resources.

Book Description
1 Plantation forests and biodiversity: Oxymoron or opportunity? Forests form the natural vegetation over much of the Earth’s land, and they are critical for the survival of innumerable organisms. The ongoing loss of natural forests, which in some regions may have taken many millennia to develop, is one of the main reasons for the decline of biodiversity. Preventing the further destruction of forests and protecting species and ecosystems within forests have become central issues for environmental agencies, forest managers, and gove- ments. In this di?cult task science has an important role in informing policy and management as to how to go about this. So how do industrial and other pl- tation forests ?t into this? Plantation forests, comprised of rows of planted trees that may be destined for pulp or sawmills after only a few years of growth, appear to have little to c- tribute to the conservation of biodiversity. Yet there is more to this than meets the eye (of the casual observer), and there are indeed numerous opportunities, and often untapped potential, for biodiversity conservation in plantation forestry. With plantation forests expanding at a rate of approximately three million hectares per year, it is crucial to understand how plantations can make a positive contribution to biodiversity conservation and how the potentially negative impacts of this land use can be minimised. That is the topic of this book.

Book Description
Biofuels global emergence in the last two decades is met with increased concerns over climate change and sustainable development. This report addresses the core issue of biofuel sustainability of biofuels and related feedstocks, drawing from a wide range of sustainability related studies, reports, policy initiatives. The report critically examines the economic, environmental and social sustainability dimensions of biofuels and review the major certification initiatives, schemes and regulations. In doing so, the report relies on extensive review of a number of country case studies covering a broad range of current biofuel-feedstocks systems. The report analysis clearly distinguish feedstock efficiency (in terms of biofuel yields per unit of land) from sustainability, especially under limiting resource (irrigated water) or sensitive areas (carbon stocks). Also, long run economic viability depend on the future policy support, technical innovations in biofuel systems, economics of biofuel supply and demand and trade-offs between food and energy uses as well as feedstock productivity gains. Biofuels can present both advantages and risks for environmental sustainability; the latter being often difficult to measure or monitor and may conflict with economic sustainability unless great strides in productivity gains are achieved. Social sustainability is the weakest link in current biofuel certification schemes owing to intrinsic local factors and as efforts target more few negative social impacts; much less focus is placed on inclusive processes that strengthen marginal stockholders participation and benefits. Biofuel certification schemes need to be more smallholder inclusive, perhaps through policy initiatives. Finally, poor developing countries, especially with abundant land and biomass production potential, need to prioritise food security and poverty reduction. In many cases, biofuel models that encourage small scale integrated bioenergy systems may offer higher rural development impacts. FDI-induced larger-scale biofuel projects, on the other hand, may be suitable in those situations where countries have sufficient industrial capacity, besides land and biomass potential, and when these biofuel projects can be fully integrated into domestic energy strategies that do not conflict with food production potential and food security.
