Download or read book Vulnerability and Adaptation Assessments written by Ron Benioff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possible impacts of global climate change on different countries has led to the development and ratification of the Framework Convention on Climate Change (FCCC) and has a strong bearing on the future sustainable development of developing countries and countries with economies in transition. The preparation of analytical methodologies and tools for carrying out assessments of vulnerability and adaptation to climate change is therefore of prime importance to these countries. Such assessments are needed to both fulfill the reporting requirements of the countries under the FCCC as well as to prepare their own climate change adaptation and mitigation plans. The vulnerability and adaptation assessment guidelines prepared by the U.S. Country Studies Program bring together all the latest knowledge and experience from around the world on both vulnerability analysis as well as adaptation methodologies. It is currently being applied successfully by scientists in over fifty countries from all the regions of the globe. This guidance is being published to share it with the wider scientific community interested in global climate change issues. This guidance document has two primary purposes: • To assist countries in making decisions about the scope and methods for their vulnerability and adaptation assessments, • To provide countries with guidance and step-by-step instructions on each of the basic elements of vulnerability and adaptation assessments.

Download or read book Darwinian Agriculture written by R. Ford Denison and published by Princeton University Press. This book was released on 2016-08-16 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: As human populations grow and resources are depleted, agriculture will need to use land, water, and other resources more efficiently and without sacrificing long-term sustainability. Darwinian Agriculture presents an entirely new approach to these challenges, one that draws on the principles of evolution and natural selection. R. Ford Denison shows how both biotechnology and traditional plant breeding can use Darwinian insights to identify promising routes for crop genetic improvement and avoid costly dead ends. Denison explains why plant traits that have been genetically optimized by individual selection--such as photosynthesis and drought tolerance--are bad candidates for genetic improvement. Traits like plant height and leaf angle, which determine the collective performance of plant communities, offer more room for improvement. Agriculturalists can also benefit from more sophisticated comparisons among natural communities and from the study of wild species in the landscapes where they evolved. Darwinian Agriculture reveals why it is sometimes better to slow or even reverse evolutionary trends when they are inconsistent with our present goals, and how we can glean new ideas from natural selection's marvelous innovations in wild species.

Download or read book Crop Ecology written by David J. Connor and published by Cambridge University Press. This book was released on 2011-04-28 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food security and environmental conservation are two of the greatest challenges facing the world today. It is predicted that food production must increase by at least 70% before 2050 to support continued population growth, though the size of the world's agricultural area will remain essentially unchanged. This updated and thoroughly revised second edition provides in-depth coverage of the impact of environmental conditions and management on crops, resource requirements for productivity and effects on soil resources. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology and morphology. System concepts are explored in detail throughout the book, giving emphasis to quantitative approaches, management strategies and tactics employed by farmers, and associated environmental issues. Drawing on key examples and highlighting the role of science, technology and economic conditions in determining management strategies, this book is suitable for agriculturalists, ecologists and environmental scientists.

Download or read book Carbon Dioxide and Terrestrial Ecosystems written by George W. Koch and published by Elsevier. This book was released on 1995-12-21 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of carbon dioxide extends from cellular to global levels of organization and potential ecological deterioration may be the result of increased CO2 in our atmosphere. Recently, the research emphasis shifted from studies of photosynthesis pathways and plant growth to ground-breaking studies of carbon dioxide balances in ecosystems, regions, and even the entire globe. Carbon Dioxide and Terrestrial Ecosystems addresses these new areas of research. Economically important woody ecosystems are emphasized because they have substantial influence on global carbon dioxide balances. Herbaceous ecosystems (e.g., grasslands, prairies, wetlands) and crop ecosystems are also covered. The interactions among organisms, communities, and ecosystems are modeled, and the book closes with an important synthesis of this growing nexus of research. Carbon Dioxide and Terrestrial Ecosystems is a compilation of detailed scientific studies that reveal how ecosystems generally, and particular plants specifically, respond to changed levels of carbon dioxide. - Contributions from an international team of experts - Empirical examination of the actual effects of carbon dioxide - Variety of terrestrial habitats investigated - Specific plants and whole ecosystems offered as studies

Download or read book Crop Ecology written by R. S. Loomis and published by Cambridge University Press. This book was released on 1992-10-08 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is centred on the 'production processes' of crops and pastures - photosynthesis and use of water and nutrients in fields. The book is unique in its combination of great breadth and depth in its treatment of production processes and systems problems. The approach is explanatory and integrative, with a firm basis in environmental physics, soils, physiology, and morphology, in contrast to descriptive or reductionist approaches. Systems concepts are introduced early and expanded as the book proceeds, giving emphasis to quantitative approaches, to management strategies and tactics employed by farmers, and to environmental issues. The systems approach is brought together in the final chapters where production and nutrient cycling are analyzed, for example farms and problems in an uncertain future are considered. The book is based on courses taught by the authors in Australia and the United States and is designed for use as a text for an introductory course in crop ecology (advanced undergraduates and beginning post-graduate level). It is more than a text, however. Given the wide range of subjects, the authors have integrated reference and background material to create a 'stand-alone' reference work useful to a wide audience of agriculturalists.
