European Market for Fruit and Vegetables (Hardcover, 1991 ed.): A. L. Hinton European Market for Fruit and Vegetables (Hardcover, 1991 ed.)
A. L. Hinton
R5,555 Discovery Miles 55 550 Ships in 10 - 15 working days

This volume presents a detailed analysis of the European market for fruit and vegetables and implications for European trade within the European Economic Community and for other countries which can benefit from participation in this trade. The book draws attention to the role of exporters, the Netherlands and the Mediterranean countries, the markets in West Germany and the United Kingdom and the market for developing countries. Whilst the level of exports of fruit and vegetables of the EEC and the United States of America is similar, imports to the EEC are considerably greater. The trade policy for fruit and vegetables of the EEC, the United States of America and Japan are discussed. There are several important export and import countries within the EEC which strongly influence the market. The author analyzes factors within these countries that explain the existing production or trade. The West German sector, which imports more fruit and vegetables than any other country, is examined. The United Kingdom is covered in the following chapter, relying heavily on domestic producers for vegetables, but looking overseas for much of its fruit. The Netherlands is the outstanding North Temperate exporter and has the efficient Dutch auction system which makes the country a major marketing and redistribution centre for both domestic and imported fresh produce. The Mediterranean exporters - Spain, Italy, Greece and Portugal - are covered next. Each of these countries has a different production and distribution system that leads to different export practices. The final chapter provides a review of global marketing opportunities for developing countries. The EEC protection, non-tariff as well as tariff, of fruit and vegetables is a handicap to the economic growth of developing countries, where fruit and vegetables frequently make an important contribution to exports. Developing countries are also disadvantaged in the production side. It is most important to improve and develop an infrastructure and the training of potential producers. It is encouraging that recent market surveys do show a promising potential market for developing countries.

Genetic Improvement of Tropical Crops (Hardcover, 1st ed. 2017): Hugo Campos, Peter D. S. Caligari Genetic Improvement of Tropical Crops (Hardcover, 1st ed. 2017)

R5,344 Discovery Miles 53 440 Ships in 12 - 17 working days

This book provides a fresh, updated perspective of the current status and perspectives in genetic improvement of a diverse array of tropical crops. The first part covers aspects which are relevant across crops, namely how to maximize the use of genetic information through modern bioinformatic approaches and how to use statistics as a tool to sustain increased genetic gains and breeding efficiency. The second part of the book provides an updated view of some seed-propagated crops, such as rice, maize and oil palm, as well as crops propagated through vegetative means such as sweet potato, cassava, banana and sugarcane. Each chapter addresses the main breeding objectives, markets served, current breeding approaches, biotechnology, genetic progress observed, and in addition a glimpse into the future for each of these selected and important tropical crops.

It is our conviction that professional skill in forestry will develop more readily and more efficiently if forestry students are presented with a clear understanding of the im pact of the physical factors that both enhance and inhibit forestry activities. Part I is analytic, written as a basic text for undergradu ates in courses such as logging, transport, forest engineer ing and even forest management. It deals with the fundamen tals of technology in forestry as determined by the physical environment. The analytic approach serves two purposes, to bring about a clear understanding of the real world of the forest and to develop tools through which efficiency and productivity can be explored, understood and improved. The principal author of this volume was Prof. Ulf sundberg. Part II discusses in some detail a wide variety of practical problems encountered by foresters. It describes harvesting systems and the principles of management and control of forest operations. The influence of the forest on operations is described at length, the terrain, topography, forest soils as well as the engineering characteristics of trees and forest stands. It also considers the impact of oper ations on the forest. The principal author of this volume was Dr. Ross Silversides. Chapters 11, 12 and 13 were written by-Prof. Sundberg."

Forest inventories throughout the world have evolved gradually over time. The content as well as the concepts and de?nitions employed are constantly adapted to the users' needs. Advanced inventory systems have been established in many countries within Europe, as well as outside Europe, as a result of development work spanning several decades, in some cases more than 100 years. With continuously increasing international agreements and commitments, the need for information has also grown drastically, and reporting requests have become more frequent and the content of the reports wider. Some of the agreements made at the international level have direct impacts on national economies and international decisions, e. g. , the Kyoto Protocol. Thus it is of utmost importance that the forest information supplied is collected and analysed using sound scienti?c principles and that the information from different countries is comparable. European National Forest Inventory (NFI) teams gathered in Vienna in 2003 to discuss the new challenges and the measures needed to get data users to take full advantage of existing NFIs. As a result, the European National Forest Inventory Network (ENFIN), a network of NFIs, was established. The ENFIN members decided to apply for funding for meetings and collaborative activities. COST- European Cooperation in Science and Technology - provided the necessary ?n- cial means for the realization of the program.

In this book I have collected many reports on the properties of bamboo. Since I started bamboo research in 1974, I have collected many publications on bamboo. However, in contacts with other researchers I became aware of the fact that several of these publications were unknown to them. Consequently their activities in research or in bamboo projects had to start at a lower level than if they had known some of these publications. Therefore, I discussed the need for a book like this with several colleagues, and I decided to start writing. In this book I present data on properties, as published by resear chers. Certainly it is not complete; e.g. the proceedings of the bamboo workshop in Cochin in November 1988 are not included; they arrived just too late to be taken into account. On the other hand, in writing this preface I realize I have forgotten my own thesis. I do apologize to any colleague whose relevant report is not taken into account as well. I like to express my feelings of respect to the board of my faculty: they allowed me to spend so much time on this book, and they gave a considerable financial support for the printing costs."

Tree based production systems abound especially in the tropics. Despite the pervasiveness of such multipurpose trees-outside-forest resources, they have not attracted adequate attention in the development paradigms of many nation states. These multispecies production systems impact the ecosystem processes favourably. Yet, our understanding of the diversity attributes and carbon dynamics under agroforestry is not adequate. This book focuses on the role of multispecies production systems involving tree and crop species as a means for carbon sequestration and thereby reduce atmospheric carbon dioxide levels. Sixteen chapters organized into three broad sections titled: Measurement and Estimation, Agrobiodiversity and Tree Management, and Policy and Socioeconomic Aspects represent a cross section of the opportunities and challenges in current research and emerging issues in harnessing carbon sequestration potential of agroforestry systems.

Plant breeders continue to make significant advances in developing high yield ing, adaptable, disease-free crops. These advances, however, are not realized until an efficient seed production system is in place that rapidly increases geneti cally superior crops and makes them available to the consumer in large quantities at a reasonable cost. Successful seed production requires seed to be genetically pure, free of admixtures, and able to establish rapidly a uniform stand. Seed production is a complex process. Rigorous production criteria are followed by both seed producer and seed companies to ensure that high-quality seed is produced and marketed. These criteria become even more stringent in hybrid seed production. This volume identifies the factors most critical in a successful seed production operation. The fundamental considerations common to all seed crops are established in Part I, Principles of Seed Production. From this founda tion, the practices of seed production are provided in detail in Part II, Seed Production of Specific Crops."

Plant tissue culture (PTC) is basic to all plant biotechnologies and is an exciting area of basic and applied sciences with considerable scope for further research. PTC is also the best approach to demonstrate the totipotency of plant cells, and to exploit it for numerous practical applications. It offers technologies for crop improvement (Haploid and Triploid production, In Vitro Fertilization, Hybrid Embryo Rescue, Variant Selection), clonal propagation (Micropropagation), virus elimination (Shoot Tip Culture), germplasm conservation, production of industrial phytochemicals, and regeneration of plants from genetically manipulated cells by recombinant DNA technology (Genetic Engineering) or cell fusion (Somatic Hybridization and Cybridization). Considerable work is being done to understand the physiology and genetics of in vitro embryogenesis and organogenesis using model systems, especially Arabidopsis and carrot, which is likely to enhance the efficiency of in vitro regeneration protocols. All these aspects are covered extensively in the present book. Since the first book on Plant Tissue Culture by Prof. P.R. White in 1943, several volumes describing different aspects of PTC have been published. Most of these are compilation of invited articles by different experts or proceedings of conferences. More recently, a number of books describing the Methods and Protocols for one or more techniques of PTC have been published which should serve as useful laboratory manuals. The impetus for writing this book was to make available a complete and up-to-date text covering all basic and applied aspects of PTC for the students and early-career researchers of plant sciences and plant / agricultural biotechnology. The book comprises of nineteen chapters profusely illustrated with self-explanatory illustrations. Most of the chapters include well-tested protocols and relevant media compositions that should be helpful in conducting laboratory experiments. For those interested in further details, Suggested Further Reading is given at the end of each chapter, and a Subject and Plant Index is provided at the end of the book.

Peatlands (or mires) cover at least 550 million ha globally, of which the greater part is situated between 50 and 70 N. Although the majority of peatlands are not used for human needs, there are large areas where agriculture, peat or wood production has been practiced. The suitability of peatlands for forestry differs from country to country depending on climatic conditions, raw wood demand, silvicultural management practice and tradition, as weH as the infrastructure in the remote areas considered. Peatland utilization for forestry may be divided into three efficiency catego- ries: (1) exploitation (harvesting oftrees with inadequate attention to regenera- tion) leading to reduction in the renewable resouree; (2) silvicultural manage- ment (harvesting of trees with natural or artificial regeneration) aimed at main- taining the renewable resource in a sustainable way; and (3) progressive rorest management (drainage, fertilization, afforestation, thinning, ditch maintenance, final harvest and regeneration) aimed at increasing the renewable resource. In North America, forestry utilization is changing from exploitation towards a kind of silvicultural management whereas progressive forest amelioration activities on forested peatlands and waterlogged mineral soils are part of the normal forestry practiees in Fennoscandinavia, the Baltic countries and Russia. In the British Isles afforestation of open peatlands is associated with drainage. This monograph is a review and synthesis of peatland forestry on northern peatland (mire) ecosystems. It covers peat soH properties, mire hydrology, car- bon and nutrient cycling, and classification of mire sites.

R3,910 Discovery Miles 39 100 Ships in 12 - 17 working days

Market globalization and the globalization of environmental concerns have spurred demand for greater international accountability for forest stewardship. In response, a range of multi-lateral governmental and non-governmental initiatives have emerged to redefine the rules of global trade, and demand verification of the legality and/or sustainability of forest products originating from within and outside national boundaries. At the same time there is a lack of transparency and shared understanding about the environmental forest policies that already exist within the world's leading forest producing and consuming countries. The result is that many stakeholders have developed perceptions about a country's regulatory environment that are not consistent with what is actually taking place. This book provides a uniquely detailed and systematic comparison of environmental forest policies and enforcement in twenty countries worldwide, covering developed, transition and developing economies. The goal is to enhance global policy learning and promote well-informed and precisely tuned policy solutions.

R3,986 Discovery Miles 39 860 Ships in 12 - 17 working days

This book describes the changing landscape of European forest ownership and explores the impact a new, often urban, generation of forest owners may have on the future of one of our most basic resources - forests. Forests have not played a major role in rural studies thus far, however they constitute an important part of many rural areas. Drawing on Swedish cases and comparison cases from various other areas of Europe, the authors present these 'new forest owners' as a pivotal factor in the changing relationships between urban and rural life. The chapters explore how forest production, the relationship to the environment, urban-rural relations and local communities have already changed as well as discussing what might be expected for the future. A result of work in the Swedish research programme PLURAL and related projects, such as the EU Cost Action FACESMAP, this volume will be of interest to scholars of forestry and rural studies, as well as to researchers in environmental, population and globalization studies more broadly.

'frees contribute a major part of fuel, fodder and fruit, and are an im of bioenergy. They are now needed in large numbers more portant source than ever before for afforestation and social forestry, so that fast-grow ing and multipurpose trees assume great importance. After extensive in discriminate deforestation and rapid depletion of genetic stocks, efforts are now being made to evolve methods for clonal mass propagation of improved and elite trees. Production of short-duration trees with a rapid turnover of biomass, and induction of genetic variability through in vitro manipulation for the production of novel fruit and forest trees, which are high-yielding and resistant to pests and diseases, and trees which display increased photosynthetic efficiency are in demand. These objectives are well within the realm of horticultural and forest biotech nology. Some of the recent advances, such as the regeneration of com plete trees from isolated protoplasts, somatic hybridization, and the Agrobacterium-mediated transformation in various tree species have opened new vistas for the genetic engineering of fruit and forest trees. This book is a continuation of the earlier volume Trees I, and presents 31 chapters on fruit, forest, nut and ornamental trees, such as avocado, pineapple, crabapple, quince, pistachio, walnut, hazelnut, date palm, oil palm, cacao, rubber, maple, sweet-gum, poplars, birches, Chinese tallow, willows, oaks, paper mulberry, rhododendrons, Scots pine, Calabrian pine, Douglas-fir, redwood, ginkgo, cycads and some flowering trees."

This open access book explores a new conceptual framework for the sustainable management of the boreal forest in the face of climate change. The boreal forest is the second-largest terrestrial biome on Earth and covers a 14 million km2 belt, representing about 25% of the Earth's forest area. Two-thirds of this forest biome is managed and supplies 37% of global wood production. These forests also provide a range of natural resources and ecosystem services essential to humanity. However, climate change is altering species distributions, natural disturbance regimes, and forest ecosystem structure and functioning. Although sustainable management is the main goal across the boreal biome, a novel framework is required to adapt forest strategies and practices to climate change. This collaborative effort draws upon 148 authors in summarizing the sustainable management of these forests and detailing the most recent experimental and observational results collected from across the boreal biome. It presents the state of sustainable management in boreal forests and highlights the critical importance of this biome in a context of global change because of these forests' key role in a range of natural processes, including carbon sequestration, nutrient cycling, and the maintaining of biodiversity. This book is an essential read for academics, students, and practitioners involved in boreal forest management. It outlines the challenges facing sustainable boreal forest management within the context of climate change and serves as a basis for establishing new research avenues, identifying future research trends, and developing climate-adapted forest management plans.

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. The authors ground their analysis in relevant theory while drawing out implications of their findings for policy and practice.

Over the last two decades, the topic of forest ecosystem services has attracted the attention of researchers, land managers, and policy makers around the globe. The services rendered by forest ecosystems range from intrinsic to anthropocentric benefits that are typically grouped as provisioning, regulating, supporting, and cultural. The research efforts, assessments, and attempts to manage forest ecosystems for their sustained services are now widely published in scientific literature. This volume focuses on broad-scale aspects of forest ecosystem services, beyond individual stands to large landscapes. In doing so, it illustrates the conceptual and practical opportunities as well as challenges involved with planning for forest ecosystem services across landscapes, regions, and nations. The goal here is to broaden the scope of land use planning through the adoption of a landscape-scale approach. Even though this approach is complex and involves multiple ecological, social, cultural, economic, and political dimensions, the landscape perspective appears to offer the best opportunity for a sustained provision of forest ecosystem services.

The need to produce food without the destructive chemical horrors of much modern farming, for an intelligent use of dwindling natural resources and for humane forms of production is universal, the practice is limited. This book is an account of one, large, instance of success in practice. Twenty-five years ago, Winin Pereira, a nuclear physicist abandoned academia to start a co-operative farm at Alonde in a tribal area north of Bombay. The group experienced, and finally discarded, all the false hopes and promises of Western originated forms of development: ploughs that ploughed too deep, irrigation systems that lowered water tables, fertilizers and pesticides which managed the earth and became so expensive that poorer farmers were dispossessed. Instead they learnt from the adivasai, or tribal people, who have nurtured or been nurtured by foresets for millennia, ways of applying popular knowledge to contemporary problems. This book is a combination of Pereira's record of achievement of sustainable livelihoods and an account of the farm and its effect on the India around it by a leading British journalist.

Plantations are playing an increasingly important part in the development and the economies of the South. Plantation Politics is the first book to examine their rationale and purpose, exposing the misconceptions and myths that have surrounded their role, and describing the contribution they can make to sustainable development. At their best, industrial plantations can become a major asset to local development by providing raw materials, infrastructure, employment, income and environmental and recreational services. At their worst, plantations, usually imposed from a 'top-down' perspective and ignoring local needs, values and rights, have monopolized land in times of food shortage, degraded wild animal and plant populations, and destroyed habitats and landscapes. The contributors analyse the conditions appropriate for both simple and complex plantations, and the contributions each can make. Complex plantations, whether established from scratch or within natural forest, are more suitable in most cases, where they are subject to numerous different claims and needs. However, their ownership, management and silviculture present new challenges ? challenges which, without the carefully researched guidelines offered here, current policy and research may well be ill-equipped to take up. Caroline Sargent is the Director and Stephen Bass is the Associate Director of the Forestry Programme at the International Institute for Environment and Development. Originally published in 1992

The destruction of the tropical forest is one of the major problems of our time. Vast areas are rapidly becoming wastelands which support only a few tough weeds, perhaps some cattle, and the farms allowed to the poor. This book provides a vision of hope: in Latin America. Africa. And South East Asia, growing numbers of people are developing techniques specifically designed to promote the wise use and preservation of remaining forest lands. However, these grassroots strategies are often ignored in favour of grandiose schemes which inevitably fail. This pattern must be broken now or the tropical forests will be lost forever.

The changing climate, the warming of the world and acid rain are among the greatest problems facing us at the end of the twentieth century. This book describes, for the first time, the effects of these phenomena on the high mountains and the forests of Europe. Mountains and the frozen regions (the cryosphere) not only play a major part in our climatic system, but are also central to our water supplies. Yet our glaciers are shrinking, our lakes and soils are becoming acidified, our forests are damaged and the whole fragile ecosystem of ranges like the Alps and the Caucasus is threatened. Nilsson and Pitt present the evidence and assess the probable effects of these changes on mountain society, tourism, water, flora and fauna. They also examine the uncertainties. Above all they look, too, at the best possible strategies in response to What is happening and at what the next steps should be. Originally published in 1991

The economic value of forest. has long been recognized, but the ways in which that value is calculated and the management policies adopted in consequence have all too often resulted in overuse and irreversible destruction. This is spectacularly obvious around the Mediterranean basin, but it is also true in northern Europe. These five case studies, commissioned by the OECD, examine failures of forest management in Britain, Spain, Italy, Germany and Sweden. They look at both market and intervention policies and show how each can further the destruction of the forests, and they set out ways in which future policies can evade the mistakes of the past.

This important book covers economic evaluation of genetic differences in animals, determination of breeding goals within an economic context and economic evaluation of breeding programs. During the last 50 years there have been great advances made in the breeding of domesticated animal species. Most of this work has been achieved through the efforts of geneticists, and often the economic goals of such advances have not been clearly evaluated. Economic Aspects of Animal Breeding redresses the balance and provides a much needed synthesis of this most important subject. The book is divided into five sections: basic concepts; economic evaluation of genetic differences; advanced topics in selection indices; economic evaluation of breeding programs, including biotechnological aspects; crossbreeding and heterosis.

Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash. Since the recognition of agroforestry as a science, curricula have been developed for agroforestry programs for undergraduate and graduate trainings in Universities. Therefore, there is an urgent need to develop and make available educational material. This textbook strives to provide up-to-date information on tropical agroforestry to serve as educational material in the tropical context. The authoritative textbook of Nair (1993) on agroforestry was published 18 years ago, and before the advent of tree domestication, an important agroforestry practice today. In addition, many other research activities, such as carbon sequestration and integrated pest management, have been included in the agroforestry agenda. This textbook is intended for agroforestry students, teachers, and practitioners.
