This book was released on 2012-12-06 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: Towards the Balance and Management of the Carbon Budget of the Biosphere The current state of misunderstanding of the global C cycle and our failure to resolve an issue that has been debated for 100 years (Jones and Henderson-Sellers, 1990) speaks loudly about the limitations of modem science when faced with the complexity of the biosphere. Efforts to understand and balance the global C budget have gone through several phases. First was a holistic view of the C budget as part of efforts to understand the geochemistry of the Earth (e. g. , Clarke, 1908). Next, came a period of data collection and sythesis which focused on the diversity of sectors of the biosphere. This phase culminated in the early 1970's with the realization that humans were greatly impacting the global C cycle as measured at the Mauna Loa Observatory (Keeling et al. , 1973). New syntheses of the global C budget emerged at this time (Woodwell and Pacan, 1973; Bolin et al. , 1979). The next phase was one of controversy and intense focus on particular sectors of the biosphere. The controversy rested on discrepancies about the role of the terrestrial biota in the global C cycle and the failure to account for sufficient C sinks to absorb all the C emitted by land-use change in the tropics (Woodwell et al. , 1978, 1983; Houghton et al. , 1983).
Download or read book Droughts written by Donald A. Wilhite and published by Routledge. This book was released on 2016-09-17 with total page 1368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drought draws together contributions from over 75 leading international researchers in the field to present the most comprehensive body of research on the physical and social dimensions of drought to date. Including an extensive range of case-studies covering the most drought-prone and most affected countries, the contributors examine new technology, planning methodologies and mitigation actions from recent drought experiences worldwide. Following a discussion of the critical concepts of drought, the work is divided into the following additional parts: · causes and predictability · monitoring and early warning techniques · impacts and assessment methodologies · links between drought and other global issues · conclusions and future challenges

Download or read book Southern African Landscapes and Environmental Change written by Peter J. Holmes and published by Routledge. This book was released on 2018-07-04 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a textbook and reference work on the physical and biotic landscapes of Southern Africa. It examines the links between these environments and the ways in which they have been, are and will likely be subject to change. It covers the geomorphology, soils, vegetation and land use across a range of landscapes, including mountains, coasts, savannah, drylands and wetlands, and identifies the impacts of current and potential climate change and other factors on these environments. The geographical focus is on the region defined by Namibia, South Africa, Botswana, Mozambique, Zimbabwe, Lesotho and Swaziland. Illustrated throughout in full colour, the book will serve as a reference volume for researchers and environmental professionals internationally, as well as a textbook for senior undergraduate and graduate-level students of geography, ecology and environmental studies in Southern Africa.

Download or read book Reference Guide to Africa written by Alfred Kagan and published by Rowman & Littlefield. This book was released on 2014-10-16 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third edition of the Reference Guide to Africa explains the most important resources for the study of the continent of Africa. It contains a general sources section and a larger disciplinary oriented section. All sources are annotated. A new edition is sorely needed since the last edition was published nine years ago. The previous editions have been successfully used in research libraries worldwide since 1999, and it has been used to teach several African studies research courses. The book provides an orientation for researching almost any topic in the arts, humanities and social sciences concerning the continent of Africa, and all of its countries and ethnic groups. The first part explains and lists portals, databases, bibliographies, indexes, guides, encyclopedias, country sources, biography, primary sources, government publications, and statistics. The second part presents 16 subject-oriented chapters, mostly in the arts, humanities and social sciences, from agriculture and food security to women studies. It covers sources that broadly cover the continent, or in some cases only North Africa (and the Middle East). It generally excludes sources limited to one country or region of Africa, except for North Africa because of the nature of the literature. One-third of the sources in this edition are new, and nearly half of them are available in electronic format. There are author/title and subject indexes. This unique work is intended for students, teachers, librarians, and researchers. It likely will be used most by reference librarians and teachers for students in high school through graduate studies. It will also be used independently by undergraduate and graduate students. It can be used to answer simple reference questions, provide the resources for an undergraduate paper, or for comprehensive work by advanced students and researchers.

This book was released on 2002-01-01 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: International agricultural research is expanding beyond the development of annual crop technologies for individual farms to the development of longer-tern natural resource management techniques for entire landscapes. But technologies of practices with a long lag time between investment and returns are unlikely to be adopted by farmers unless they have secure rights to the underlying resources (property rights). Similarly, technologies that span multiple farms are unlikely to be adopted unless neighbors and groups work together (collective action). But little is know about the way property rights and collective action in developing countries mediate the adoption of technologies by farmers and groups. To address this information gap, this volume brings together international experts in economics, sociology, and natural resource management to examine the links among property rights, collective action, and technological change for a variety of technologies across a rage of community contexts in the developing world.

Download or read book Land Tenure and Natural Resource Management written by Keijiro Otsuka and published by Intl Food Policy Res Inst. This book was released on 2001-08-14 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The devastating environmental effects of deforestation and the exploitation of other natural resources in the developing world have been well documented, yet their impact on local communities has received far less attention. This volume fills this gap by looking at how land degradation and deforestation are being addressed at the local level, where households have experienced the reduction of farm size and the decline of natural resources. Through a comparison of Asia and Africa, Land Tenure and Natural Resource Management examines the evolution of land tenure institutions within diverse cultural, natural, and policy environments. Specific topics include the evolution of customary land tenure, the impacts of land tenure policies, and common property management. The editors conclude that the best strategy for managing land and forest resources lies in promoting the establishment of property rights and investment in the improvement of the natural resource base. Topics Include: Issues and Theoretical Framework; Quantitative Methodology; Agroforestry Management in Ghana; Agroforestry Management in Sumatra; Tree and Cropland Management in Malawi; Customary and Private Land Management in Uganda; Management of State Land and Privatization in Vietnam; Common Property Forest Management in the Hill Region of Nepal; Timber Forest Management in Nepal and Japan Toward New Paradigms of Land and Tree Resource Management.
