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.
Download or read book Ex Situ Plant Conservation written by Center for Plant Conservation and published by Island Press. This book was released on 2013-02-22 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faced with widespread and devastating loss of biodiversity in wild habitats, scientists have developed innovative strategies for studying and protecting targeted plant and animal species in "off-site" facilities such as botanic gardens and zoos. Such ex situ work is an increasingly important component of conservation and restoration efforts. Ex Situ Plant Conservation, edited by Edward O. Guerrant Jr., Kayri Havens, and Mike Maunder, is the first book to address integrated plant conservation strategies and to examine the scientific, technical, and strategic bases of the ex situ approach. The book examines where and how ex situ investment can best support in situ conservation. Ex Situ Plant Conservation outlines the role, value, and limits of ex situ conservation as well as updating best management practices for the field, and is an invaluable resource for plant conservation practitioners at botanic gardens, zoos, and other conservation organizations; students and faculty in conservation biology and related fields; managers of protected areas and other public and private lands; and policymakers and members of the international community concerned with species conservation.

Download or read book The Ex Situ Conservation of Plant Genetic Resources written by J.G. Hawkes and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a distressing truism that the human race during the last millennium has caused the exponential loss of plant genetic diversity throughout the world. This has had direct and negative economic, political and social consequences for the human race, which at the same time has failed to exploit fully the positive benefits that might result from conserving and exploiting the world's plant genetic resources. However, a strong movement to halt this loss of plant diversity and enhance its utilisation for the benefit of all humanity has been underway since the 1960's (Frankel and Bennett, 1970; Frankel and Hawkes, 1975). This initiative was taken up by the Convention on Biological Diversity (CBD, 1992) that not only expounds the need to conserve biological diversity but links conservation to exploitation and development for the benefit of all. Article 8 of the Convention clearly states the need to develop more effective and efficient guidelines to conserve biological diversity, while Article 9, along with the FAO International Undertaking on Plant Genetic Resources, promotes the adoption of a complementary approach to conservation that incorporates both ex situ and in situ techniques.
Download or read book Plant Conservation written by Timothy Walker and published by Timber Press. This book was released on 2013-12-03 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants’ ability to turn sunlight into energy makes them the basis for all life; without them there is no life. And they are more than just a food source—they provide us with fuel, fibers, and pharmaceuticals. Global warming and the destruction of natural habitats are a serious threat to many plants, and there are worldwide efforts to mitigate the disaster. Plant Conservation tackles this essential topic head on. Timothy Walker, as the director of the Oxford Botanical Garden, a leader in the field of plant conservation, plays a key role in this effort. He highlights what is happening now, from cataloging the world’s flora to conservation efforts like protecting plants from overcollecting. He also shows home gardeners how they can become involved, whether by growing their own food to decrease reliance on large agriculture or by making smart plant choices by growing natives and avoiding invasives. Plant Conservation treats a critical topic in an accessible and optimistic way. It is required reading for students, professionals, and anyone with a keen interest in the importance of plants.
Download or read book Plant Conservation written by Gary A. Krupnick and published by . This book was released on 2005 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural history has always been the foundation of conservation biology. For centuries, botanists collected specimens in the field to understand plant diversity; now that many habitats are threatened, botanists have turned their focus to conservation, and, increasingly, they look to the collections of museums, herbaria, and botanical gardens for insight on developing informed management programs. Plant Conservation explores the value of these collections in light of contemporary biodiversity studies. Plant Conservation opens with a broad view of plant biodiversity and then considers evolutionary and taxonomic threats and consequences of habitat alteration; specific threats to plant diversity, such as invasive species and global climate change; consequences of plant population decline at the ecological, evolutionary, and taxonomic levels; and, finally, management strategies that protect plant biodiversity from further decline. With a unique perspective on biodiversity and scientific collections, Plant Conservation ultimately emphasizes the role museums and botanical gardens will play in future conservation.
Download or read book Conservation of Threatened Plants written by J. Simmons and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last hlO hundred years man has changed from living in equilibrium with the natural world which sustained him, to a new position in which he is now its undisputed ruler - and very often out of equilibrium - able in a matter of hours to reduce miles of forest to devastated, potential desert. This destructive and wasteful ability has increas~d dramatically over recent years. At the same time however the need for conservation, particularly of plants as a resource for the future, has also become apparent, along with the realisation that advanced technologies can produce more from existing agricultural and forest regions. This may to some extent relieve the heavy pressure on the vulnerable areas where short term over-exploitation leads to permanent destruction of whole ecosystems, and the attendant loss, for ever, of many of the animals and plants which originally lived there. There still remains today a vast number of plant species whose potential is unknown. Maybe they will never have more than aesthetic value to mankind. But who knows where, for example, the next anti cancer agent may be found. And anyway future generations may not be ready to accept such anthropocentric values, and the options should be kept open for the philosophical concept that all life on earth has a right to exist and that man has none to exterminate.
Download or read book Biodiversity and Conservation of Woody Plants written by M. R. Ahuja and published by Springer. This book was released on 2017-11-21 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides complete, comprehensive, and broad subject-based reviews for students, teachers, researchers, policymakers, conservationists, and NGOs interested in the biodiversity and conservation of woody plants. Forests cover approximately 31 percent of the world’s total landmass; 93 percent is natural forest and only 7 percent consists of planted trees. Forest decline is progressing at an alarming rate worldwide. In addition to human activities (logging, deforestation, and exploiting forest lands for agriculture and industrial use), a number of other factors – including pests and diseases, drought, soil acidity, radiation, and ozone – are cumulatively contributing to global forest decline. The present situation forces us to focus on forest conservation strategies for the present and future. Gene conservation and maintaining genetic diversity in forest ecosystems are crucial to the preservation of forest genetic resources. This calls for integrated action to implement both the in situ (on site) preservation of forest stands and ex situ (distant from the original site) strategies for the conservation of woody plants’ genetic resources. Selected priority areas include: 1) assessing patterns of genetic diversity and threats, 2) understanding the biological processes regulating genetic diversity, 3) assessing the impact of human activities and climate change on genetic diversity, and 5) finding methods for prioritizing species and populations for the conservation of forest trees genetic resources. All chapters were written by leading scientists in their respective fields, which include: woody plant diversity, ecology and evolution; assessment of genetic diversity in forest tree populations; conservation planning under climate change; and in situ and ex situ strategies, including biotechnological approaches, for the conservation of woody plants genetic resources.
Download or read book Community Biodiversity Management written by Walter Simon de Boef and published by Routledge. This book was released on 2013-03-12 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conservation and sustainable use of biodiversity are issues that have been high on the policy agenda since the first Earth Summit in Rio in 1992. As part of efforts to implement in situ conservation, a methodology referred to as community biodiversity management (CBM) has been developed by those engaged in this arena. CBM contributes to the empowerment of farming communities to manage their biological resources and make informed decisions on the conservation and use of agrobiodiversity. This book is the first to set out a clear overview of CBM as a methodology for meeting socio-environmental changes. CBM is shown to be a key strategy that promotes community resilience, and contributes to the conservation of plant genetic resources. The authors present the underlying concepts and theories of CBM as well as its methodology and practices, and introduce case studies primarily from Brazil, Ethiopia, France, India, and Nepal. Contributors include farmers, leaders of farmers’ organizations, professionals from conservation and development organizations, students and scientists. The book offers inspiration to all those involved in the conservation and use of agrobiodiversity within livelihood development and presents ideas for the implementation of farmers’ rights. The wide collection of experiences illustrates the efforts made by communities throughout the world to cope with change while using diversity and engaging in learning processes. It links these grassroots efforts with debates in policy arenas as a means to respond to the unpredictable changes, such as climate change, that communities face in sustaining their livelihoods.

Download or read book Plant Conservation written by Alan Hamilton and published by Earthscan. This book was released on 2013 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this, the latest in the People and Plants series, plant conservation is described in the context of livelihoods and development, and ways of balancing the conservation of plant diversity with the use of plants and the environment for human benefit are discussed. A central contention in this book is that local people must be involved if conservation is to be successful. Also examined are ways of prioritizing plants and places for conservation initiatives, approaches to in situ and ex situ conservation, and how to approach problems of unsustainable harvesting of wild plants. Roles for botanists, foresters, sociologists, development workers and others are discussed. This book acts as a unifying text for the series, integrating case studies and methodologies considered in previous volumes and pointing out in a comprehensive, accessible volume the valuable lessons to be learned.

Download or read book Plant Resources for Food Fuel and Conservation written by Robert James Henry and published by Earthscan. This book was released on 2010 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Agriculture and food production have a large footprint on the landscape globally and compete for space with land for nature conservation. This book explores the competition between the food needs of a growing human population and the conservation of biodiversity as intensified by the emerging use of crops for energy production. As concern about the impact of greenhouse gas emissions on climate grows and oil prices increase, energy production from agricultural crops has become a significant industry. At the same time, growth in food demand due to population growth has been accelerated by growing affluence associated with economic growth in major developing countries increasing per capita consumption. Consumers are concerned that the price of food will continue to increase sharply as a result of this competition but a loss of biodiversity may be another major outcome. Drawing on his expertise in plant conservation genetics, the author provides a balanced appraisal of the potential for developing new or improved crops for food or bioenergy production in the context of climate change, while at the same time protecting biodiversity."--Back cover.
