Book excerpt: The papers included in this Special Issue address a variety of important aspects of plant biodiversity and genetic resources, including definitions, descriptions, and illustrations of different components and their value for food and nutrition security, breeding, and environmental services. Furthermore, comprehensive information is provided regarding conservation approaches and techniques for plant genetic resources, policy aspects, and results of biological, genetic, morphological, economic, social, and breeding-related research activities. The complexity and vulnerability of (plant) biodiversity and its inherent genetic resources, as an integral part of the contextual ecosystem and the human web of life, are clearly demonstrated in this Special Issue, and for several encountered problems and constraints, possible approaches or solutions are presented to overcome these.

Download or read book Genetic Diversity and Erosion in Plants written by M. R. Ahuja and published by Springer. This book was released on 2015-11-06 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Custodians of Biodiversity written by Manuel Ruiz and published by Routledge. This book was released on 2012-03-15 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globally, local and indigenous approaches to conserving biodiversity, crop improvement, and managing precious natural resources are under threat. Many communities have to deal with 'biopiracy,' for example. As well, existing laws are usually unsuitable for protecting indigenous and traditional knowledge and for recognizing collective rights, such as in cases of participatory plant breeding, where farmers, researchers and others join forces to improve existing crop varieties or develop new ones, based on shared knowledge and resources. This book addresses these issues. It outlines the national and international policy processes that are currently underway to protect local genetic resources and related traditional knowledge and the challenges these initiatives have faced. In particular these themes are addressed within the context of the Convention of Biological Diversity and the International Treaty on Plant Genetic Resources for Food and Agriculture. The authors broaden the policy and legal debates beyond the sphere of policy experts to include the knowledge-holders themselves. These are the 'custodians of biodiversity': farmers, herders and fishers in local communities. Their experience in sharing access and benefits to genetic resources is shown to be crucial for the development of effective national and international agreements. The book presents and analyzes this experience, including case studies from China, Cuba, Honduras, Jordan, Nepal, Peru and Syria.

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 Protecting Biodiversity written by International Development Research Centre (Canada) and published by IDRC. This book was released on 2000 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the countries of South and North America are found some of the most diverse collections of flora and fauna in the world. Colombia alone carries over 50 thousand different plant species. This precious resource, however, is quickly dwindling. Pharmaceutical and biotechnology companies are tapping America's genetic resources at an ever-increasing rate, and habitat destruction has pushed many species to extinction or to the brink of extinction. "Protecting Biodiversity" addresses one of the most fundamental aspects of this important issue: the lack of adequate national laws regulating access to, and compensation for, the use of local genetic resources. This book is the first to compare such laws and policies across a range of countries in both the industrialized and developing worlds, including Argentina, Canada, Colombia, Costa Rica, Paraguay, Peru, and the United States. It also presents legal viewpoints, conclusions, and solid recommendations for future action. "Protecting Biodiversity" is the newest reference book in the rapidly emerging legal field that combines environmental, intellectual property, contract, and administrative law.

Download or read book Plant Genetic Conservation written by Nigel Maxted and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 462 pages. 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.
