It is universally agreed that a catastrophic loss of plant genetic diversity is occurring. Some species and, perhaps more importantly, gene combinations are being lost for perpetuity. Following the signing of the Biodiversity Convention in Rio there is even more awareness of the need to conserve the world's biodiversity. In recent years for various scientific and political reasons, the practical application of conservation has switched away from ex situ toward in situ techniques, i.e. the maintenance of germplasm in its natural "wild" habitat or within traditional agricultural systems. This text aims to provide a practical and theoretical introduction to the technique of in situ genetic conservation.

Plant diversity sustains all animal life, and the genetic diversity within plants underpins global food security. This text provides a practical and theoretical introduction to the strategies and actions to adopt for conserving plant genetic variation, as well as explaining how humans can exploit this diversity for sustainable development. Notably readable, it initially offers current knowledge on the characterization and evaluation of plant genetic resources. The authors then discuss strategies from in situ and ex situ conservation to crop breeding, exploring how these can be used to improve food security in the face of increasing agrobiodiversity loss, human population growth and climate change. Each chapter draws on examples from the literature or the authors' research and includes further reading references. Containing other useful features such as a glossary, it is invaluable for professionals and undergraduate and graduate students in plant sciences, ecology, conservation, genetics and natural resource management.

It should be useful reading for second-year undergraduate courses in plant biology and plant genetic conservation, and also be valuable for postgraduate courses in plant genetics, conservation and cell biology. It provides information for professional plant conservationists. This work covers ex situ genetic resources conservation.

Genetic erosion, that is, the loss of native plant and genetic diversity has been exponential from the Mediterranean Basin through the 20th century. This careless eradication of species and genetic diversity as a result of human activities from a "hot-spot" of diversity threatens sustainable agriculture and food security for the temperate regions of the world. Since the early 1900s there has been a largely ad hoc movement to halt the loss of plant diversity and enhance its utilization. The Convention on Biological Diversity and Food and Agriculture Organization of the United Nations International Undertaking on Plant Genetic Resources, both highlight the need to improve conservation methodologies and enhance utilisation techniques. It has been argued that the most important component of biodiversity is the genetic diversity of crop and forage species used to feed humans and livestock. These cultivated and related wild species provides the raw material for further selection and improvement.Leguminosae species are of major economic importance (peas, chickpeas, lentils and faba beans, as well as numerous forage species) and provide a particularly rich source of protein for human and animal foods. Their distribution is concentrated in the Mediterranean region and therefore the improvement of their conservation and use in the region is critical. This text is designed to help ensure an adequate breadth of legume diversity is conserved and to help maximize the use of that conserved diversity. The subjects of conservation and use of legume diversity, the Mediterranean ecosystem and taxonomy of legumes are introduced. Generic reviews of the taxonomy, centre of diversity, ecogeographic distribution, genetic diversity distribution, conservation status, conservation gaps and future research needs are provided, along with a discussion of the importance of rhizobia to the maintenance of legume diversity. Current ex situ and in situ conservation activities as well current legume uses are reviewed. In conclusion future priorities for ex situ and in situ plant genetic conservation and use of Mediterranean legumes are highlighted.All contributors look forward rather than simply reviewing past and current activities and therefore it is hoped that the identification of genetic erosion, location of taxonomic and genetic diversity and promotion of more efficient utilization of conserved material will be enhanced.

Two major challenges to continued global food security are the ever increasing demand for  food products, and the unprecedented abiotic stresses that crops face due to climate change.Wild relatives of domesticated crops serve as a reservoir of genetic material, with the potential to be used to develop new, improved varieties of crops. Crop Wild Relative and Climate Change integrates crop evolution, breeding technologies and biotechnologies, improved practices and sustainable approaches while exploring the role wild relatives could play in increasing agricultural output. Crop Wild Relative and Climate Change begins with overviews of the impacts of climate change on growing environments and the challenges that agricultural production face in coming years and decades. Chapters then explore crop evolution and the potential for crop wild relatives to contribute novel genetic resources to the breeding of more resilient and productive crops. Breeding technologies and biotechnological advances that are being used to incorporate key genetic traits of wild relatives into crop varieties are also covered. There is also a valuable discussion on the importance of conserving genetic resources to ensure continued successful crop production.  A timely resource, Crop Wild Relative and Climate Change will be an invaluable resource for the crop science community for years to come.

Maintaining food security in the face of human population increase and climate change is one of the critical challenges facing us in the 21st Century. Utilisation of the full range of agrobiodiversity will be a necessary tool in addressing this challenge. In this book a team of international contributors review all aspects of utilization and conservation of crop wild relative (CWR) and landrace (LR) diversity as a basis for crop improvement and future food security. Enhancing Crop Genepool Use covers four key areas: · Characterization techniques - novel 'omics' techniques and predictive tools that can be used to identify adaptive traits and expedite plant breeding. · Conservation strategies - how to develop national, regional and global CWR and LR conservation strategies, how better to target conservation to meet the needs of the plant breeding community, and how to integrate CWR and LR diversity into existing biodiversity conservation programmes. · Facilitating CWR and LR use - pre-breeding using 'exotic' germplasm, meeting breeders' needs, integrating the conservation and user communities, and policy enhancement. · Informatics development - improving characterization, trait and conservation data management and accessibility, and inter-information system operability. This book will appeal to a wide array of specialists and postgraduate students, such as those working in the fields of agrobiodiversity conservation and use, conservation, ecology, botany, genetics, plant breeding and agriculture.

Crop wild relatives (CWR) are species closely related to crop plants which can contribute beneficial traits, such as pest or disease resistance and yield improvement. These species are critical for improving agricultural production and increasing food security. They are also essential components of natural and semi-natural habitats as well as agricultural systems, and are therefore vital in maintaining ecosystem health. However, CWR, like any other group of wild species, are subject to an increasing range of threats: habitat loss, degradation and mismanagement, over-collection and climate change. Through an examination of the national, regional and global context of CWR, these authoritative studies present methodologies and case studies that review and provide recommendations for global conservation and use. Topics range from the establishment of conservation priorities and strategies, threat assessment and genetic erosion and pollution.

Conservation in protected areas has focused on preserving biodiversity of ecosystems and species, whereas conserving the genetic diversity contained within species has historically often been ignored. However, maintaining genetic diversity is fundamental to food security and the provision of raw materials and it is best preserved within plants' natural habitats. This is particularly true for wild plants that are directly related to crop species and can play a key role in providing beneficial traits, such as pest or disease resistance and yield improvement. These wild relatives are presently threatened due to processes of habitat destruction and change and methodologies have been adapted to provide in-situ conservation through the establishment of genetic reserves within the existing network of protected areas. Providing a long-awaited synthesis of these new methodologies, this book presents a practical set of management guidelines that can be used for the conservation of plant genetic diversity of crop wild relatives in protected areas.

Based on the 2010 conference 'Towards the establishment of genetic reserves for crop wild relatives and landraces in Europe', this book is the cutting edge discussion of agrobiodiversity conservation. By considering the benefits of understanding and preserving crop wild relatives and landraces, it encompasses issues as wide-ranging and topical as habitat protection, ecosystem health and food security. Focusing on Europe, but globally relevant, Agrobiodiversity Conservation is ideal for postgraduate students of conservation and environmental studies, conservation professionals, policy makers and researchers.

The Asian beans and grams, the species of Vigna (subgenus Ceratotropis), include several legumes that are an essential component in the diets of a large proportion of Asia's population, and interest in these legumes is growing as ethnic cuisine spreads worldwide. However, this important group of legumes is little known compared to the closely related Phaseolus beans and soybean. That deficiency is addressed for the first time in this fully illustrated comprehensive conservation, genetics, taxonomic, and agricultural monograph on the genetic resources of the Asian Vigna. The book deals with the phylogeny of the group from the perspectives of morphological and molecular analyses, ex situ and in situ conservation, eco-geographical analyses, and research. In addition, morphological descriptions, keys, and eco-geographic details of each species in the group are provided. This genetic resources handbook and guide to the Asian Vigna will be a valuable reference for agriculturists, conservationists, taxonomists, other scientists, and students interested in the legumes and plant genetic resources.
