Book Synopsis Progress in Nitrogen Cycling Studies by : O. van Cleemput
Download or read book Progress in Nitrogen Cycling Studies written by O. van Cleemput and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the `8th Nitrogen Workshop' which was held at the University of Ghent, Belgium, from 5 to 8 September 1994. Although nitrogen dynamics in different ecosystems have been studied for several decades, new orientations and other emphases have recently emerged. Previously, nitrogen was considered as an essential element mostly in terms of productivity, but now, more emphasis is attached to environmental consequences. More than 100 contributions in this book tackle recent developments within the fields of nitrogen advice systems, plant response to fertilization, immobilization and mobilization, nitrification, denitrification, leaching, ammonia volatilization and biological nitrogen fixation. A large number of papers is devoted to the formation of gaseous nitrogen compounds, while mineralization-immobilization is another topic of important interest. The book also contains the reports of discussion groups on different aspects of the nitrogen cycle.

Download or read book Nitrogen Fixation in Tropical Cropping Systems written by Ken E. Giller and published by CABI. This book was released on 2001-01-01 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this book, first published in 1991 and intended for students and researchers, contains revised and updated material on the theory and practice of nitrogen fixation in tropical cropping systems. There are 15 chapters in 3 parts. Part I, Introduction, contains 5 chapters on tropical environments (climate, soils and cropping systems), nitrogen fixing organisms, the process of nitrogen fixation, assessment of the role of nitrogen fixation, and cycling of nitrogen in tropical cropping systems. Part II, Tropical crops and cropping systems, comprises 7 chapters on freeliving, root-associated and endophytic nitrogen fixing bacteria of cereal crops and grasses, cyanobacteria and Azolla as green manure for wetland rice, grain legumes, legumes as green manures and cover crops, forage legumes, understorey legumes and shade trees in plantation crops, and nitrogen fixing trees in agroforestry. Part III, optimizing nitrogen fixation, includes 3 chapters on environmental constraints, approaches to enhancement, and future impacts on nitrogen fixation in tropical agriculture. A list of common names and subject index are included.

Book Synopsis Human Security and the Environment by : Edward Page
Download or read book Human Security and the Environment written by Edward Page and published by Edward Elgar Publishing. This book was released on 2002-01-01 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the post-Cold War era, the pre-eminent threats to our security derive from human degradation of vital ecosystems as well as the possibility of war and terrorist attack. This substantial book examines this new 'security-environment' paradigm and the way in which the activities of societies are shifting the balance with nature. The distinguished authors investigate this redefinition of security with particular reference to environmental threats such as climate change and the availability of adequate supplies of food and water. They illustrate how unfettered economic growth, rising levels of personal consumption and unsustainable natural resource and energy procurement are taking a heavy toll on the global environment. This, in turn, is forcing both developed and developing countries to re-evaluate the more immediate environmental security of their own populations. For a truly global perspective, the authors present a series of country case-studies, looking at issues of security and environment, and comparing how they influence policy and human well-being. They also discuss a number of theoretical issues which underpin discussions of 'environmental security', demonstrating that this is a relatively new and essentially contested concept.

Book Synopsis Shifting Cultivation and Environmental Change by : Malcolm F. Cairns
Download or read book Shifting Cultivation and Environmental Change written by Malcolm F. Cairns and published by Routledge. This book was released on 2015-01-09 with total page 1057 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shifting cultivation is one of the oldest forms of subsistence agriculture and is still practised by millions of poor people in the tropics. Typically it involves clearing land (often forest) for the growing of crops for a few years, and then moving on to new sites, leaving the earlier ground fallow to regain its soil fertility. This book brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Some critics have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, the book shows that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment and local communities. The book focuses on successful agricultural strategies of upland farmers, particularly in south and south-east Asia, and presents over 50 contributions by scholars from around the world and from various disciplines, including agricultural economics, ecology and anthropology. It is a sequel to the much praised "Voices from the Forest: Integrating Indigenous Knowledge into Sustainable Upland Farming" (RFF Press, 2007), but all chapters are completely new and there is a greater emphasis on the contemporary challenges of climate change and biodiversity conservation.

Book Synopsis Soil and Soil Fertility Management Research in Sub-Saharan Africa by : Henk Mutsaers
Download or read book Soil and Soil Fertility Management Research in Sub-Saharan Africa written by Henk Mutsaers and published by Routledge. This book was released on 2017-03-27 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Judicious soil fertility management is crucial for sustainable crop production and food security in sub-Saharan Africa (SSA). This book describes the various concepts and approaches underlying soil and soil fertility management research in SSA over the last fifty years. It provides examples of important innovations generated and assesses the position of research within the research-to-development continuum, including how innovations have been validated with the intended beneficiaries. Using the experience of the International Institute of Tropical Agriculture (IITA) as a case study, the authors analyse how processes, partnerships and other factors have affected research priorities, the delivery of outputs, and their uptake by farming communities in SSA. They evaluate both successes and failures of past investments in soil fertility research and important lessons learnt which provide crucial information for national and international scientists currently engaged in this research area. The book is organised in a number of chapters each covering a chronological period characterised by its primary research content and approaches and by the dominant research paradigms and delivery models.
