The tropics are the source of many of our familiar fruits, vegetables, oils, and spice, as well as such commodities as rubber and wood. Moreover, other tropical fruits and vegetables are being introduced into our markets to offer variety to our diet. Now, as tropical forests are increasingly threatened, we face a double-fold crisis: not only the loss of the plants but also rich pools of potentially useful genes. Wild populations of crop plants harbor genes that can improve the productivity and disease resistance of cultivated crops, many of which are vital to developing economies and to global commerce. Eight chapters of this book are devoted to a variety of tropical crops—beverages, fruit, starch, oil, resins, fuelwood, fodder, spices, timber, and nuts—the history of their domestication, their uses today, and the known extent of their gene pools, both domesticated and wild. Drawing on broad research, the authors also consider conservation strategies such as parks and reserves, corporate holdings, gene banks and tissue culture collections, and debt-for-nature swaps. They stress the need for a sensitive balance between conservation and the economic well-being of local populations. If economic growth is part of the conservation effort, local populations and governments will be more strongly motivated to save their natural resources. Distinctly practical and soundly informative, this book provides insight into the overwhelming abundance of tropical forests, an unsettling sense of what we may lose if they are destroyed, and a deep appreciation for the delicate relationships between tropical forest plants and people around the world.

In Regreening the Bare Hills: Tropical Forest Restoration in the Asia-Pacific Region, David Lamb explores how reforestation might be carried out both to conserve biological diversity and to improve the livelihoods of the rural poor. While both issues have attracted considerable attention in recent years, this book takes a significant step, by integrating ecological and silvicultural knowledge within the context of the social and economic issues that can determine the success or failure of tropical forest landscape restoration. Describing new approaches to the reforestation of degraded lands in the Asia-Pacific tropics, the book reviews current approaches to reforestation throughout the region, paying particular attention to those which incorporate native species – including in multi-species plantations. It presents case studies from across the Asia-Pacific region and discusses how the silvicultural methods needed to manage these ‘new’ plantations will differ from conventional methods. It also explores how reforestation might be made more attractive to smallholders and how trade-offs between production and conservation are most easily made at a landscape scale. The book concludes with a discussion of how future forest restoration may be affected by some current ecological and socio-economic trends now underway. The book represents a valuable resource for reforestation managers and policy makers wishing to promote these new silvicultural approaches, as well as for conservationists, development experts and researchers with an interest in forest restoration. Combining a theoretical-research perspective with practical aspects of restoration, the book will be equally valuable to practitioners and academics, while the lessons drawn from these discussions will have relevance elsewhere throughout the tropics.

In nature, radiata pine is very localised and an obscure tree species despite the romantic character of much of its natural habitat. That obscure status and the lack of any reputation as a virgin timber slowed its due recognition as a commercial crop. Nevertheless, it has become a major plantation forest crop internationally. It has become the pre-eminent commercial forest species in New Zealand, Chile and Australia, with important plantings in some other countries. It consequently features prominently in the international trade in forest products, in addition to its importance in domestic markets of grower countries. Very fast growth, considerable site tolerances, ease of raising in nurseries and transplanting, and ease of processing and using its wood for a range of products and purposes, have made it the utility softwood of choice almost everywhere it can be grown satisfactorily. Abundant genetic variation and its amenability to other management inputs created special opportunities for its domestication. The story of its domestication forms a classic case history in the development of modern commercial forestry, with trailblazing in both genetic improvement and plantation management; this inevitably meant a learning process that provided instructive lessons, especially for tree breeders dealing with some other species. Paradoxically, the plantation monocultures have played and can continue to play an important role in protecting natural forests and other forms of biodiversity. Given the attractions of growing radiata pine, there were inevitably cases of overreach in planting it, with lessons to be learnt. Economic globalisation has meant globalisation of pests and disease organisms, and the scale on which radiata pine is grown has meant is has been the focus of various biotic alarms, none of which have proved catastrophic. Temptations, remain, however, to pay less than due attention to some aspects of risk management. The chapter structure of the book is based on historical periods, beginning long before any important human influences, and ending with a look into what the future might hold for the species and its role in human and ecological sustainability. Almost throughout, there has been complex interplay between the technical aspects, local social and economic factors, various types of institution, the enthusiasm and drive of some very influential individuals, and tides of economic ideology, threads that needed to be woven together to do the story justice.

Currently in Tanzania, training institutions for professionals in cross-cutting sectors such as forestry and agriculture do not adequately capture the role of forest and tree resources for food security and nutrition, leading to dependency on one sector – agriculture – to cater for food and nutrition diversity. This undervalues the fundamental role of forest ecosystem services for sustainable agriculture by regulating water flows, stabilizing soils, maintaining soil fertility, regulating the climate, and providing habitat for wild pollinators and predators of agricultural pests. Provision of education on sustainable forests and trees for food security and nutrition at all levels seems to be the most conceivable entry point to ensure that adequate knowledge and skills are imparted to professionals. The goals of this training manual are to: enhance the recognition and significance of forestry to food security and nutrition through the sustainable management and use of forests and trees2; enhance the food security and nutrition benefits from the forests and trees; enhance and stimulate research and training capacity; strengthen institutional frameworks by incorporating food security and nutrition objectives in forest management policies, programmes and projects; and develop value chains based on forest and tree resources for sustainable development in the country. The overall objective is to create awareness and enable increased investment in the forestry sector for food security and nutrition in Tanzania. This training manual is also meant to serve as a useful tool for sharing and exchanging knowledge and experiences across different regions (within the country) and beyond.

From the time of hunter-gatherers to the present day, forests have played a vital role in the development of humanity and society. This broad introductory textbook sets world forestry in a social, environmental, historical, and economic context. The development of forests, grassland and humans is described from the Devonian through to the Age of Agriculture, covering the factors determining the distribution of forests, the classification of forest types, the value and benefits of the forest and the products of the forest and their associated trade. The book also explores issues such as sustainable forest management, current patterns of deforestation and reforestation, and future challenges facing our forests. Fully updated throughout and with new contributions from international experts, this second edition includes new chapters on climate change and international forest policy, and expanded coverage of forest products and bioenergy production.

This volume is a collection of 31 multi-authored, rigorously peer-reviewed chapters on different aspects of agroforestry, produced as a compendium on the occasion of the 1st World Congress of Agroforestry, June 2004. Its contenst include a tropical-temperate mix of topics, which is a rare feature of a publication of this nature. Several of the chapters are on topics that have not been discussed or described much in agroforestry literature. A third feature is that some of the authors, though well known in their own disciplinary areas, are somewhat new to agroforestry; the perceptions and outlooks of these scholars who are relatively uninfluenced by the past happenings in agroforestry gives a whole new dimension to agroforestry and broadens the scope of the subject. Finally, rather than just reviewing and summarizing past work, most chapters take the extra effort in attempting to outline the next steps. Agroforestry stands to gain enormously from the infusion of these new and different ideas and bold initiatives, thus making the title "New Vistas" quite justifiable.

This new edition provides an update on the considerable amount of evidence on tree-crop interactions which has accumulated during the last two decades, especially on the more complex multi-strata agroforestry systems, which are typical of the humid tropics. In addition three new chapters have been added to describe the new advances in the relationship between climate change adaptation, rural development and how trees and agroforestry will contribute to a likely reduction in vulnerability to climate change in developing countries

This guide sets out the main issues and significant challenges, and suggests solutions and guidelines for viable NTFP-based SMFEs. Government, nongovernmental agencies and their business partners have important roles to play in developing this sector from its vibrant, but largely informal status. This can be achieved by creating a more enabling, consistent and credible business and forest management framework of support, regulation and policy, that offers more and better opportunities to all those involved in getting a product from the forest to consumers.
