This book provides a quantitative analysis of the role of woody plants in semi-arid regions, for the aSSessment of their benefits in agrosylvopastoralland-use systems with productive and sus tainability objectives. The insights presented and conclusions drawn allow the additional benefits of woody plants for specific climatic and physical site conditions and land-use systems to be estimated. The Sahel and Sudan zones in West Africa, on which the book focusses, represent resource-poor conditions, whose ecological dynamics have been relatively well studied. The role of woody plants in this region, as assessed in this book, is extrapolated to other semi-arid regions, leading to general conclusions on agroforestry's potential as an option for sustainable land use in semi-arid regions. The origins of this book go back to 1982, when the Club du Sahel requested that available data on woody plants in the Sahel region be synthesised, to provide basic information to enable better attention to be given to woody plants in rural development programmes. We are grateful to the Club du Sahel for this challenge. Various people contributed to studies used in this book. The preliminary inventory of the data available was made by Frits Ohler; later his work was continued by Franciska Dekker.

The increasing world population is already causing intensive pressure on the most productive areas of the earth's surface. Hopes of improved living standards, if realised, will increase the pressure still further. The need to make better use of less productive areas thus becomes an urgent priority for human endeavour. In this respect, the arid and semi-arid regions of the world, occupying about 11,000 million acres or 4,500 million hectares, roughly one third of the tota11and surface, pose a constant challenge to man's technological skill. Though the possibilities of economic use of the real deserts are inherently limited, there remain vast areas with less extreme conditions where sustained research is capable of yielding substantial gains in pro ductivity. The problem is so large that it can be solved only by the coordinated efforts of workers in many countries and many disciplines. Forestry has a special part to play, not only for its potential value for wood production but still more for the beneficial effects of shelter from desiccating winds which so commonly accompany arid conditions. Mr. KA UL is to be congratulated on his initiative to pool the results of research on afforestation in arid zones in many parts of the world, and to present them in a single volume in the form of separate monographs.

Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.

With detailed data from nine sites around the world, the authors examine how the so-called ‘fragmentation’ of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. ‘Rangelands’ make up a quarter of the world’s landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.

This book integrates the latest global developments in forestry science and practice and their relevance for the sustainable management of tropical forests. The influence of social dimensions on the development of silvicultural concepts is another spotlight. Ecology and silvicultural options form all tropical continents, and forest formations from dry to moist forests and from lowland to mountain forests are covered. Review chapters which guide readers through this complex subject integrate numerous illustrative and quantitative case studies by experts from all over the world. On the basis of a cross-sectional evaluation of the case studies presented, the authors put forward possible silvicultural contributions towards sustainability in a changing world. The book is addressed to a broad readership from forestry and environmental disciplines.

Many countries around the world are engaged in decentralization processes, and most African countries face serious problems with forest governance, from benefits sharing to illegality and sustainable forest management. This book summarizes experiences to date on the extent and nature of decentralization and its outcomes, most of which suggest an underperformance of governance reforms, and explores the viability of different governance instruments in the context of weak governance and expanding commercial pressures over forests. Findings are grouped into two thematic areas: decentralization, livelihoods and sustainable forest management; and international trade, finance and forest sector governance reforms. The authors examine diverse forces shaping the forest sector, including the theory and practice of decentralization, usurpation of authority, corruption and illegality, inequitable patterns of benefits capture and expansion of international trade in timber and carbon credits, and discuss related outcomes on livelihoods, forest condition and equity. The book builds on earlier volumes exploring different dimensions of decentralization and perspectives from other world regions, and distills dimensions of forest governance that are both unique to Africa and representative of broader global patterns. Authors ground their analysis in relevant theory while attempting to distill implications of their findings for policy and practice.

Large areas of the world’s forests have been lost or degraded and landscapes everywhere are being simplified by current land-use practices. In this publication, Lamb and Gilmour present approaches to restoring and rehabilitating the vast areas of degraded, fragmented and modified forests which cover much of the world. They argue that by applying best practice at the site level it is possible to enhance socio-economic and ecological gains at the landscape level. This book provides an important contribution towards the objectives of the Forest Landscape Restoration approach and is essential reading for practitioners and decision makers involved in forest restoration.

The 21st century has seen the beginnings of a great restoration effort towards the world’s forests, accompanied by the emergence of an increasing literature on reforestation, regeneration and regrowth of forest cover. Yet to date, there is no volume which synthesises current knowledge on the extent, trends, patterns and drivers of reforestation. This edited volume draws together research from leading researchers to explore reforestation and forest regrowth across the world, from multiple dimensions – including ecosystem services, protected areas, social institutions, economic transitions, remediation of environmental problems, conservation and land abandonment – and at different scales. Detailing the methods and analyses used from across a wide range of disciplines, and incorporating research from North, South and Central America, Africa, Asia and Europe, this groundbreaking book provides a global overview of current trends, explores their underlying causes and proposes future forest trajectories. The first of its kind, the book will provide an invaluable reference for researchers and students involved in interdisciplinary research and working on issues relevant to the biophysical, geographic, socioeconomic and institutional processes associated with reforestation.

In this urgent time, World on the Edge calls out the pivotal environmental issues and how to solve them now. We are in a race between political and natural tipping points. Can we close coal-fired power plants fast enough to save the Greenland ice sheet and avoid catastrophic sea level rise? Can we raise water productivity fast enough to halt the depletion of aquifers and avoid water-driven food shortages? Can we cope with peak water and peak oil at the same time? These are some of the issues Lester R. Brown skilfully distils in World on the Edge. Bringing decades of research and analysis into play, he provides the responses needed to reclaim our future.

The lack of sufficient access to clean water is a common problem faced by communities, efforts to alleviate poverty and gender inequality and improve economic growth in developing countries. While reforms have been implemented to manage water resources, these have taken little notice of how people use and manage their water and have had limited effect at the ground level. On the other hand, regulations developed within communities are livelihood-oriented and provide incentives for collective action but they can also be hierarchal, enforcing power and gender inequalities. This book shows how bringing together the strengths of community-based laws rooted in user participation and the formalized legal systems of the public sector, water management regimes will be more able to reach their goals.

Understanding how ecosystems are assembled -- how the species that make up a particular biological community arrive in an area, survive, and interact with other species -- is key to successfully restoring degraded ecosystems. Yet little attention has been paid to the idea of assembly rules in ecological restoration, in both the scientific literature and in on-the-ground restoration efforts. Assembly Rules and Restoration Ecology, edited by Vicky M. Temperton, Richard J. Hobbs, Tim Nuttle, and Stefan Halle, addresses that shortcoming, offering an introduction, overview, and synthesis of the potential role of assembly rules theory in restoration ecology. It brings together information and ideas relating to ecosystem assembly in a restoration context, and includes material from a wide geographic range and a variety of perspectives. Assembly Rules and Restoration Ecology contributes new knowledge and ideas to the subjects of assembly rules and restoration ecology and represents an important summary of the current status of an emerging field. It combines theoretical and practical aspects of restoration, making it a vital compendium of information and ideas for restoration ecologists, professionals, and practitioners.
