Available in PDF, EPUB and Kindle. Book excerpt: Plant Resources of Arid and Semiarid Lands: A Global Perspective is a collection of papers that evaluates the existing native plant resources in the arid and semiarid regions. The papers deal with the resources found in these arid regions such as food potential, forage, fuel, fiber, medicinal or industrial uses. The book covers the arid regions of Africa, Australia, the Indian subcontinent, Middle East, North America, China, South America, and the USSR. The treatment of these regions includes geographical descriptions such as area, annual precipitation, temperature, humidity, wind ranges or patterns, and seasons. These papers also discuss the effects of topography on water drainage and loss, the basic soil types, holding capacity, water runoffs, and the availability of water (surface and subsurface), The book examines the current and projected growth rates for relevant countries and dry regions in each continent. These papers discuss the economic output from arid lands, the balance of trade, current or developing resources, as well as the prospects of these countries with dry regions. The book also focuses on the types of plants found in these regions whether these are used for food, forage, medicine or for industry. This collection is suitable for environmentalists, ecologists, sociologist, anthropologists, and researchers involved in biological and environmental conservation.

Book excerpt: The international conference Arid Lands: Today and Tomorrow drew more than 400 participants from over 3 S countries to Tucson, Arizona, for one week in October of 19 8 S. The diversity of presenters, disciplines and subject matters addressed contributed to an interesting and informative conference. The papers presented in this volume represent the efforts of scientists and other individuals who, through their various disciplines, are addressing the problems of and opportunities presented by the arid lands of the world. A committee of five scientists reviewed for substance. relevance and their contribution to the conference the 284 abstracts that were submitted. They selected 146 for presentation at the conference and of those papers presented, 128 were received for inclusion in the proceedings.

Download or read book Plants for Arid Lands written by G.E. Wickens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.

Available in PDF, EPUB and Kindle. Book excerpt: First published in 1995. This title presents the proceedings of The Second International Conference on Range Management in the Arabian Gulf, 1990. The objectives of the Conference were to: evaluate progress made following the First Conference; exchange information on range management development; review advances in applicable technologies; discuss potential strategies for range enhancement and assemble pertinent recommendations for enactment. As such, these proceedings will serve as a reference base for researchers, professors, lecturers, and students alike, both at advanced undergraduate and graduate levels.

Book excerpt: A unique and comprehensive introduction to contemporary development issues in East and Southern Africa, and represents a significant departure from the often descriptive approach adopted by existing regional and development texts on African regions. Each contribution is carefully chosen to highlight the theoretical basis to development issues, and the practical problems of implementing development plans, in this vital subregion. Overall this produces comprehensive and balanced coverage of historical, economic, political and social issues. The twin issues of globalisation and modernisation give the book a clear focus.

Download or read book Geology and Plant Life written by Arthur R. Kruckeberg and published by University of Washington Press. This book was released on 2004 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before any other influences began to fashion life and its lavish diversity, geological events created the initial environments--both physical and chemical--for the evolutionary drama that followed. Drawing on case histories from around the world, Arthur Kruckeberg demonstrates the role of landforms and rock types in producing the unique geographical distributions of plants and in stimulating evolutionary diversification. His examples range throughout the rich and heterogeneous tapestry of the earth's surface: the dramatic variations of mountainous topography, the undulating ground and crevices of level limestone karst, and the subtle realm of sand dunes. He describes the ongoing evolutionary consequences of the geology-plant interface and the often underestimated role of geology in shaping climate. Kruckeberg explores the fundamental connection between plants and geology, including the historical roots of geobotany, the reciprocal relations between geology and other environmental influences, geomorphology and its connection with plant life, lithology as a potent selective agent for plants, and the physical and biological influences of soils. Special emphasis is given to the responses of plants to exceptional rock types and their soils--serpentines, limestones, and other azonal (exceptional) substrates. Edaphic ecology, especially of serpentines, has been his specialty for years. Kruckeberg's research fills a significant gap in the field of environmental science by connecting the conventionally separated disciplines of the physical and biological sciences. Geology and Plant Life is the result of more than forty years of research into the question of why certain plants grow on certain soils and certain terrain structures, and what happens when this relationship is disrupted by human agents. It will be useful to a wide spectrum of professionals in the natural sciences: plant ecologists, paleobiologists, climatologists, soil scientists, geologists, geographers, and conservation scientists, as well as serious amateurs in natural history.
Download or read book Soil Carbon in Sensitive European Ecosystems written by Robert Jandl and published by John Wiley & Sons. This book was released on 2011-10-20 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Carbon in Sensitive European Ecosystems - From Science to Land Management is a comprehensive overview of the latest research in this field drawn together by a network of scientists from across Europe. Soil carbon assessments are crucial at present to our understanding of the dynamics of terrestrial ecosystems and our ability to assess implications for the global carbon exchange and its consequences on the future climate. This book focuses primarily on ecosystems and their soil carbon stocks. The book identifies three key sensitive ecosystems within Europe: Mediterranean Forest and Agricultural Systems; Mountains; and Peatland. Contributors include those currently working for the European research programme, COST Action 639 BurnOut (www.cost639.net; 2006-2010). COST Action 639 emerged from a demand from policy makers in Europe for more detailed information on soil carbon dynamics. The cooperation between experts for reporting and experts for soil dynamics is the focus of the book. This book seeks to provide an up-to-date account on the state-of-the-art research within this topical field.
