This book combines several ideas and philosophies and provides a detailed discussion on the value addition of fruits, vegetables, spices, plantation crops, floricultural crops and in forestry. Separate chapters address the packaging, preservation, drying, dehydration, total quality management and supply chain management of horticultural crops. The book explains value addition as a process of increasing the economic value and consumer appeal of a commodity with special reference to horticultural crops. Each chapter focuses on a specific area, exploring value addition as a production/ marketing strategy driven by customer needs and preferences. But, as such, it is also a more creative field, calling for more imagination than calculated, routine work. Value is added to the particular produce item when the product is still available when the season is out and the demand for the product exceeds the available supply. Value addition is an important factor in the growth and development of the horticultural sector, both in India and around the world. But very little information is available on this particular aspect of horticulture. Albert Einstein famously said, "Try not to become a man of success, but rather try to become a man of value." This message is not only true for those people who want to make more of themselves, but also for those who want their creation or product in any form to excel. And it certainly applies to horticultural crops, which are extremely perishable. It is true that loss reduction is normally less costly than equivalent increases in production. The loss of fresh produce can be minimized by adopting different processing and preservation techniques to convert the fresh vegetables into suitable value-added and diversified products, which will help to reduce the market glut during harvest season. Value-added processed products are products that can be obtained from main products and by-products after some sort of processing and subsequently marketed for an increased profit margin. Generally speaking, value-added products indicate that for the same volume of primary products, a higher price is achieved by means of processing, packing, enhancing the quality or other such methods. The integrated approach from harvesting to the delivery into the hands of the consumer, if handled properly, can add value to fresh produce on the market. But most of the fresh produce has a limited life, although it can be stored at appropriate temperature and relative humidity for the same time. If such produce is processed just after harvesting, it adds value and stabilizes the processed products for a longer time. Preparing processed products will provide more variety to consumers and improve the taste and other sensory properties of food. This will also promote their fortification with nutrients that are lacking in fresh produce. By adopting suitable methods for processing and value addition, the shelf life of fresh produce can be increased manifold, which supports their availability year-round to a wider spectrum of consumers on both the domestic and international market. With increased urbanization, rising middle class purchasing power, changing food habits and a decline in making preserved products in individual homes, there is now a higher demand for industry-made products on the domestic market. In spite of all these aspects, only 1-2.2% of the total produce is processed in developing countries, as compared to 40-83% in developed countries. The horticultural export industry offers an important source of employment for developing countries. For instance, horticulture accounts for 30% of India's agricultural GDP from 8.5% of cropped area. India is the primary producer of spices, second largest producer of fruits and vegetables and holds a prominent position with regard to most plantation crops in the world. The cultivation of horticultural crops is substantially more labor-intensive than growing cereal crops and offers more post-harvest opportunities for the development of value-added products. This book offers a valuable guide for students of horticulture, as well as a comprehensive resource for educators, scientists, industrial personnel, amateur growers and farmers.

Forest Diversity and Management (Hardcover, 2006 ed.): David L. Hawksworth, Alan T. Bull Forest Diversity and Management (Hardcover, 2006 ed.)

R7,750 Discovery Miles 77 500 Ships in 18 - 22 working days

Natural forests with thousands of years of ecological continuity are unrivalled as the treasure store of terrestrial biodiversity on Earth. And while there is currently no fully comprehensive inventory of the biota associated with any given forest, it is reasonable to assume that in conserving natural forests we can conserve the myriads of unnamed bacteria, fungi, insects, mites and nematodes that forests support.

Drawing on diverse research from biodiversity experts around the world, this collection of papers reflects the diversity of forest types and forest issues that concern forest scientists globally. Forest types considered vary from savannah and tropical rainforests to the ancient oak forests of Poland; issues explored include the effects of logging, management practices, forest dynamics and climate change on forest structure and biodiversity.

Given the range of topics covered, this book should be of particular interest to those involved in teaching forest conservation and management, as well as to researchers requiring an overview of current work in forest diversity, conservation and sustainable management.

'This book has been written by a team of experts from a wide variety of institutions... The result is by far the most comprehensive and easy to understand treatment of FLR yet written.' ACHIM STEINER (DIRECTOR GENERAL, IUCN) AND MANOEL SOBRAL FILHO (EXECUTIVE DIRECTOR, ITTO), FROM THE PREFACE Forest loss and degradation have caused a decline in the quality of ecosystem services around the world. But fixing the problem takes more than just planting trees; practitioners increasingly realize that a landscape approach is essential. This handbook, authored and edited by international authorities in the field of forestry, is the first practical guide to using forest landscape restoration (FLR) to repair the damage done to forest lands by poor land management practice. Using research backed by respected institutions such as ITTO and the World Conservation Union (IUCN), it explains how to increase the resilience of landscapes and the communities they support through FLR. The main aim of FLR is not to re-establish pristine forest, even if this were possible; rather, the objective is to make landscapes more resilient and thereby keep future management options open. It also aims to support communities as they strive to increase and sustain the benefits they derive from land management. This book explains the concept of FLR and guides the reader through the steps that must be taken to put it into practice. It is an indispensable aid for practitioners in all aspects of forestry and natural resource management. Published with ITTO and IUCN

R1,365 Discovery Miles 13 650 Ships in 9 - 17 working days

When first published in 2009, Nature's Matrix set out a radical new approach to the conservation of biodiversity. This new edition pushes the frontier of the biodiversity/agriculture debate further, making an even stronger case for the need to transform agriculture and support small- and medium-scale agroecology and food sovereignty. In the first edition, the authors set out a radical new approach to the conservation of biodiversity. This is based on the concept of a landscape as a matrix of diverse, small-scale agricultural ecosystems, providing opportunities to enhance conservation under the stewardship of local farmers. This contrasts with the alternative view of industrial-scale farms and large protected areas which exclude local people. However, since then the debate around conservation and agriculture has developed significantly and this is reflected in this updated second edition. The text is thoroughly revised, including: a reorganization of chapters with new and timely topics introduced, updates to the discussion of agroecology and food sovereignty, bringing it in line with the current debates, greater coverage of the role of agroecology, in particular agroforestry, as an important component of climate change adaptation and mitigation, highlighting recent studies on the role of intensive agriculture in climate change and loss of biodiversity, and more attention given to the discussion of land sparing versus land sharing. By integrating the ecological aspects of agriculture and conservation biology, with a political and social analysis as well as historical perspective, the book continues to set a progressive agenda and appeals to a wide range of students and professionals.

Learn how the principles and practices of landscape agroecology can help to overcome drought, flooding, poor soil, damaging winds, plant diseases, plant-eating insects, and more! Examining the concepts, conventions, and components that underlie the ecology of human-managed landscapes, this is the first book to address landscape agroecology. Incorporating ideas from agroecology, forestry, agronomy, agroforestry, landscape ecology, and environmental science, Landscape Agroecology is a comprehensive look at a cutting-edge topic. From the author: Farm or forestry landscapes can be designed to address any number of objectives. Commonly, the focus is entirely on production with few, if any, secondary goals. These landscapes typically achieve their purpose but are not entirely in harmony with nature. Landscape agroecology offers the same potential for productivity, but also focuses on sustainability and environmental friendliness as strong secondary objectives. While the idea of formulating landscapes for specific purposes is comparatively new, countless examples exist where landscape modifications have been made to inhospitable areas in order to overcome the natural obstacles that hamper crop growth. This book illuminates the principles behind these triumphs, bringing this local knowledge into the mainstream. Landscape Agroecology will familiarize you with the concepts and terminology needed to understand this exciting new field: complementarityusually defined in terms of plant-plant growthexpanded to include the rural countryside desirable agroecosystems propertieswhat an agroecosystem needs in order to overcome landscape stresses such as drought, flooding, insect infestation, etc. agrotechnologiesthe classification of agroecosystems based on visual characteristics and the land-use problems addressed cultural agroecologywhat we can learn from the superior land-use techniques of various societies and cultures, and how these ideas can be brought into the mainstream cultural motifculturally related land-use patterns that are openly manifested in the landscape Essential for university/college libraries and for research stations as well as professors and students of agroecology, this book will be referred to again and again. In addition to basic agroecological concepts, chapters in this essential book address the management of wind, water, and pests; biodiversity; physical and temporal patterns; principal, auxiliary, and temporal agrotechnologies, and much more. For professors and students in environmental science, this book offers many previously un-dicussed alternatives for resolving the earth's environmental dilemmas.

Adaptation and Fitness in Animal Populations - Evolutionary and Breeding Perspectives on Genetic Resource Management... Adaptation and Fitness in Animal Populations - Evolutionary and Breeding Perspectives on Genetic Resource Management (Hardcover, 2009 ed.)
Julius Van Der Werf, Hans-Ulrich Graser, Richard Frankham, Cedric Gondro
R5,284 Discovery Miles 52 840 Ships in 18 - 22 working days

Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production.

Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use.

Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources.

This book had an ambitious goal in bringing together a sample of the world s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

Forests and woodlands provide an enormous range of goods and services to society, from timber and firewood to medicinal plants, watershed protection, destinations for tourists and sacred sites. Only when these are understood and valued can forests and their resources be properly managed and conserved. This work shows how the complicated network of benefits can be untangled and sets out the different approaches needed to value them. It covers the analysis of plant-based markets, non-market valuation and decision frameworks such as cost-benefit analysis.

The Magaliesberg by Vincent Carruthers was first published in 1990. A second edition was published in 2000 and reprinted in 2007. It has now been revised again for publication to coincide with the international proclamation of the Magaliesberg Biosphere. The book has been highly successful and is a valuable source of information about the Magaliesberg, its geology, biodiversity and human history. During the decades since its publication substantial changes have taken place in in South Africa and in the Magaliesberg region and the revised editions to the book have taken cognisance of these. Most importantly, The Magaliesberg has had a profound influence on government and public awareness of the region and it has led directly to application to UNESCO for the Magaliesberg to be registered as a Biosphere Reserve in June 2014. This international recognition of the importance of the area will greatly enhance conservation efforts and stimulate tourism, education and research in the region. The current edition of the book celebrates this accomplishment and it will continue to be the primary source of information for public readership. The Magaliesberg mountains are more than two billion years old - one of the oldest mountain ranges on the planet – and the book traces their creation and the changes in the landscape over this vast passage of time. The ancient geomorphology has given rise to a wide spectrum of different habitats and a consequent diversity of plant and animal life. The book’s extensive descriptions of the fauna and flora of the area inspire the reader to consider the impact that man has on his environment. Each of the main plant and animal groups – trees, flowers, birds, mammals, reptiles and insects – has a full chapter devoted to it with checklists of every species found in the area indicating both the Scientific as well as common names. The second half of the book is dedicated to the immensely rich human history of the Magaliesberg and is equally comprehensive. Starting with the pre-hominid ancestors of humankind it describes the paleontological and archaeological evidence of the succession of people who have lived in the mountains over hundreds of thousands of years. Stone Age tools and etchings, Iron Age walled villages as well as the forts and battlefields of more recent centuries are all brought to life in detailed accounts of the people and events of the time. Carruthers’s eloquent writing style is easy to read and grabs the reader’s attention from the start. The comprehensive book is based on exhaustive research and is complemented by numerous illustrations and full-colour photographs. Carruthers’s love for the area is obvious and he describes the Magaliesberg as a ‘priceless national asset’, which this book has helped, and continues to help, to preserve. The many full-colour and black and white photographs, as well as detailed illustrations on every page, add value to the book and make it a publication that appeals to those readers who are academically inclined, as well as those who are amateur environmentalists or historians.
