Book Description
This book contains edited and revised papers from a conference on 'Science and Technology for Managing Plant Genetic Diversity in the 21st Century' held in Malaysia in June 2000, organised by the International Plant Genetic Resources Institute (IPGRI). It includes keynote papers and some 40 additional ones, covering ten themes.The major scientific challenges to developing a global vision for the next century are identified and key research objectives are also discussed.

Book Description
This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.

Book Description
Land and water management is especially critical as the use of upstream watersheds can drastically affect large numbers of people living in downstream watersheds. This work examines the institutional and technical context for managing watersheds and river basins, including the involvement of both the public and private sectors.

Book Description
Genetic erosion is the loss of genetic diversity within a species. It can happen very quickly, due to catastrophic events, or changes in land use leading to habitat loss. But it can also occur more gradually and remain unnoticed for a long time. One of the main causes of genetic erosion is the replacement of local varieties by modern varieties. Other causes include environmental degradation, urbanization, and land clearing through deforestation and brush fires. In order to conserve biodiversity in plants, it is important to targets three independent levels that include ecosystems, species and genes. Genetic diversity is important to a species’ fitness, long-term viability, and ability to adapt to changing environmental conditions. Chapters in this book are written by leading geneticists, molecular biologists and other specialists on relevant topics on genetic erosion and conservation genetic diversity in plants. This divisible set of two volumes deals with a broad spectrum of topics on genetic erosion, and approaches to biodiversity conservation in crop plants and trees. Volume 1 deals with indicators and prevention of genetic erosion, while volume 2 covers genetic diversity and erosion in a number of plants species. These two volumes will also be useful to botanists, biotechnologists, environmentalists, policy makers, conservationists, and NGOs working to manage genetic erosion and biodiversity.

Book Description
This book in the series “Sustainable Development and Biodiversity” contains peer-reviewed chapters from leading academicians and researchers around the world in the field of horticulture, plant taxonomy, plant biotechnology, genetics and related areas of biodiversity science centered on genetic diversity. This book includes original research reviews (national, regional and global) and case studies in genetic diversity in fruits and vegetables, horticulture, and ecology from sub-tropical and tropical regions. It is unique as it covers a wide array of topics covering global interests and will constitute valuable reference material for students, researchers, extension specialists, farmers and certification agencies who are concerned with biodiversity, ecology and sustainable development.

Book Description
Genes in the Field: Conserving Plant Diversity on Farms is a comprehensive collection of papers focusing on agricultural conservation and diversity issues throughout the world. Recently, regional and local farm seed variety has been reduced because of increased population, agricultural science and technology and the integration of the world's many diverse cultures. Because of this, diversity on individual farms across wide regions is threatened by modern crop varieties that have been bred for broad adaptation, resistance to disease, and other risk factors such as their ability to better use water, fertilizer, and higher yields. The concern of the farmers to maintain production levels and income often seems incompatible with those whose focus is on the maintenance of viable and sustainable ecosystems and maintaining genetic diversity. Exploring and understanding these different concerns is an essential starting point for answering some of the key questions about the implementation of "on farm" conservation and the role of local cultivators in sustainable development.

Book Description
This collection starts by reviewing key issues such as valuing, identifying and monitoring plant genetic diversity. The book goes on to assess advances in in-situ and on-farm strategies for protecting crop wild relatives and landraces. Chapters cover topics such as local strategies for preserving crop genetic resources, in-situ management of wild plant populations, monitoring genetic diversity and collecting wild varieties. The book also discusses community-based conservation strategies, participatory plant breeding programmes and seed systems to ensure farmer access to improved varieties. Part 4 reviews key challenges facing ex-situ collections such as genebanks, including improved storage and conservation techniques. Parts 5 and 6 assesses improvements in characterising and evaluating plant genetic resources such as DNA-based screening and phenotyping, as well as ways of improving the quality and exchange of information and germplasm for use in breeding improved varieties.

Book Description
One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

Book Description
Our lives and well being intimately depend on the exploitation of the plant genetic resources available to our breeding programs. Therefore, more extensive exploration and effective exploitation of plant genetic resources are essential prerequisites for the release of improved cultivars. Accordingly, the remarkable progress in genomics approaches and more recently in sequencing and bioinformatics offers unprecedented opportunities for mining germplasm collections, mapping and cloning loci of interest, identifying novel alleles and deploying them for breeding purposes. This book collects 48 highly interdisciplinary articles describing how genomics improves our capacity to characterize and harness natural and artificially induced variation in order to boost crop productivity and provide consumers with high-quality food. This book will be an invaluable reference for all those interested in managing, mining and harnessing the genetic richness of plant genetic resources.
