Available in PDF, EPUB and Kindle. Book excerpt: The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade the importance of natural resources for sustainable agricultural development has been increasingly discussed at international forums and conferences. Aside from the sustainable management of soil, water, and air, it now seems to be accepted that the sustainable management of genetic resources is one of the four indispensable preconditions for a sustainable agriculture. The discussion on conservation of plant genetic resources for food and agriculture (PGRFA), however, has to reflect the costs of conservation as well. These have not yet been discussed intensively. The study analyzes the conservation costs of plant genetic resources; it also assesses the effectiveness of conservation and the efficiency of the different conservation instruments. It is based on extensive surveys in relevant countries. Following the detailed cost and impact analysis, the results show that the effectiveness of conservation strategies may be increased.

Book excerpt: In the United States, the critical task of preserving our plant genetic resources is the responsibility of the National Plant Germplasm System (NPGS). NPGS undergoes a thorough analysis in this book, which offers wide-ranging recommendations for equipping the agency to better meet U.S. needsâ€"and lead international conservation efforts. The book outlines the importance and status of plant genetic conservation and evaluates NPGS's multifaceted operations. Two options for revamping NPGS within the U.S. Department of Agriculture are included.
Download or read book Plant Genetic Resources written by Ehsan Dulloo and published by Burleigh Dodds Agricultural Sc. This book was released on 2021-03-23 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Plant Genetic Resources and Food Security written by Christine Frison and published by Routledge. This book was released on 2012-06-25 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) is a pivotal piece of recent legislation, providing a route map for the use of such resources for sustainable agriculture and food security. Plant Genetic Resources and Food Security explains clearly the different interests and views at stake between all players in the global food chain. It touches upon many issues such as international food governance and policy, economic aspects of food and seed trade, conservation and sustainable use of food and agricultural biodiversity, hunger alleviation, ecological concerns, consumers' protection, fairness and equity between nations and generations, plant breeding techniques and socio-economic benefits related to food local economies. The book shows that despite the conflicting interests at stake, players managed to come to an agreement on food and agriculture for the sake of food security and hunger alleviation in the world. Published with the Food and Agriculture Organization (FAO) of the United Nations and with Bioversity International.
Download or read book Conservation and Utilization of Horticultural Genetic Resources written by P.E. Rajasekharan and published by Springer. This book was released on 2019-06-25 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation of crop genetic resources is one of the important elements in efforts to sustainably increase agricultural production in low-income countries, and to guarantee long-term food security, especially for the low-income population groups in these countries. Horticultural crops, as high-value crops, have an important role to play in revitalizing rural economies and can add significantly to national economies. Moreover, horticulture provides more than twice the number of jobs compared to traditional cereal crop production, and the shifting of conventional agriculture towards high-value horticulture has increased employment opportunities in developing countries. To exploit this potential, researchers need a vast array of horticultural genetic resources and information on new traits. Horticultural crops, which are only a part of PGRFA (Plant Genetic Resources for Food and Agriculture), are characterized by a wide and varied range of species. In fact, there are five major horticultural crop groups: fruit and nut crops, vegetables, food legumes, roots and tubers, and lastly the ornamental and medicinal group. In this context, the present book provides a comprehensive overview of the current state of conservation and utilization of horticultural genetic resources, addressing contemporary approaches to conservation in connection with different technologies, including biotechnological approaches as practised in India and in some cases, globally. It includes a brief chapter on the unique nature of horticultural genetic resources, providing a rationale for viewing them as being distinct from field crop genetic resources. Subsequent chapters share insights on protocols for the conservation of selected horticultural crops ex situ, and focus on the increased need to complement these efforts with in situ conservation approaches. Geospatial tools are also briefly described, emphasizing their utility with regard to mapping and managing resources. The book also explores the wild gene pool in horticulture crops; discusses legal aspects related to horticultural genetic resources and biotechnological aspects; and describes the key aspects of sustainable management and replenishment. Given its scope, the book offers a valuable resource for all horticulturists, graduate students, researchers, policymakers, conservationists, and NGOs engaged in horticulture in particular and biodiversity in general.
