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.

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.

Download or read book The Arid Zones written by Hilton Kramer and published by Routledge. This book was released on 2017-07-05 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hot and temperate deserts and their marginal steppe lands comprise one-third of the land surface of the world and are an increasingly critical area for the economic wellbeing of world populations. The remarkable mechanisms of floral, faunal, and human adaptation to the distinct and difficult environment of these arid zones, as well as the potential of modern technology for facilitating adaptation, are described and explained by Walton in the light of our most recent knowledge of the phenomena and processes involved.Beginning with a clarification of the definitions of arid and semi-arid regions and with the delineation of techniques for measuring the degree of aridity in these areas, the author shows that there is wide variation among the arid zones in landscape and climate and that there are numerous local and microclimates within any single arid region. The life cycles of the plants and animals of the arid zones are described and the water resources, including problems of salinity, mineral contamination, and the construction of reservoirs, are examined. Extensive treatment is given to potential agricultural adaptations and to pastoralism as the most widespread response to dry land. A final chapter summarizes attempts at adaptation to prevailing drought and discusses the kinds of future development that the author deems most likely in arid zones.Throughout the book emphasis is placed on specific, detailed analysis, with adequate tables and formulas for in-depth understanding of particular aspects of aridity. Examples from both Old and New Worlds are used to demonstrate the spheres in which progress is being made and to show the mistakes in past and present land use in arid areas. An essential supplement for courses in physical geography, the book will be useful in many area studies and in studies of economic development.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Wildland Shrubs, Their Biology and Utilization: An International Symposium, Utah State University, Logan, Utah, July 1971 In the past, arid and semiarid regions were defined on the basis of climatic factors alone (koppen 1923; Mathews 1931; Lang 1920; de Martonne 1905; Thornthwaite 1948; Transeau 1905; Emberger 1930; Gorczynski 1943; Stenz 1946; Boyko accord ingly, dpen's world map included Thar and Rajasthan under desert climate and the surrounding portion that extends up to Cutch and Gujarat, and certain parts of Madras are included under Steppe climate. However, since vegetation is the result of the response of plants to many variables of the climatic factors, no single factor can characterize deserts or arid and semiarid regions. Pramanik, Hariharan, and Ghose (1952) defined deserts or arid regions of India as areas having rainfall of 10 inches or less and a mean annual diurnal temperature range of 24° F. Or more; they defined semiarid regions as areas having rainfall ranging from 10 to 20 inches and an annual diurnal temperature range of 18° F. Or more. However, a correlation of climate and vegetation led Bharucha (1955) to retain as the limit of the arid zone the 10 inches isohyet, while the limit of the semiarid zone at the 30 inches isohyet. On the basis of these criteria as well as those of Thornthwaite the areas of arid and semi arid zones in India total sq. Km. And sq. Km respectively (table this excludes the cold desert of Jammu and Kashmir State, which contains sq. Km. Of arid and sq. Km. Of semiarid areas (krishnan Figure 1 gives the distribution and delimitation of these zones. In the North, next to Rajasthan, Gujarat has the largest area within the arid zone. In South India, the arid region is mainly confined to a portion of Rayalaseema region in Andhra Pradesh (fig. 1) and adjoining parts of Mysore. Of the semiarid zone, 59 percent is situated in peninsular India. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Steppes written by Michael Bone and published by Timber Press. This book was released on 2015-07-15 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steppes—semi-arid biomes dominated by forbs, grasses, and grass-like species, and characterized by extremes of cold and heat—occupy enormous areas on four continents. Yet these ecosystems are among the least studied on our planet. Given that the birth and evolution of human beings have been so intimately interwoven with steppe regions, it is amazing that so few attempts have been made to compare and quantify the features of these regions. In this ground-breaking volume, five leading voices in horticulture—all staff members of Denver Botanic Gardens—examine the plants, climate, geology, and geography of the world’s steppes: central Asia, central and intermountain North America, Patagonia, and South Africa. Drawing upon their first-hand experience, the writers illuminate the distinctive features of each region, with a particular emphasis on the striking similarities between their floras. Each chapter includes a primer of species of horticultural interest—a rich resource for readers with an interest in steppe plants.

This book was released on 2012-12-06 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters in this section place the problems of vegetation and climate interactions in semi-arid regions into the context which recur throughout the book. First, Verstraete and Schwartz review desertification as a process of global change evaluating both the human and climatic factors. The theme of human impact and land management is discussed further by Roberts whose review focuses on semi-arid land-use planning. In the third and final chapter in this section we return to the meteorological theme. Nicholls reviews the effects of El Nino/Southern Oscillation on Australian vegetation stressing, in particular, the interaction between plants and their climatic environment.

Download or read book Reclamation of Arid Lands written by Mohammad Jafari and published by Springer. This book was released on 2017-10-31 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of arid and semi-arid lands conditions, their general characteristics, methods of management, conservation, exploitation and reclamation. It also focuses on how to utilize the potential of arid lands with the minimum manipulation and alteration. Arid and semi-arid areas represent a major part of natural ecosystems not only in Iran, but around the world, and mismanagement and inappropriate exploitation of these areas may lead to further gradual degradation. As such, an understanding of the characteristics of these areas is vital if they are to be conserved and reclaimed.
Download or read book Management of Semi Arid Ecosystems written by B.H. Walker and published by Elsevier. This book was released on 2012-12-02 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive regions of the world have a climate which, whilst permitting development of a continuous vegetative cover, is too dry for successful annual cropping. These are the semi-arid areas where land use is based on the natural vegetation. Easily degraded and difficult to maintain, they are under increasing pressure as expanding human populations move in and endeavour to force a living from them. As a result they contain some of the worst examples of resource degradation. This book examines the problems and opportunities involved in man's use of semi-arid areas. The authors are all actively involved in research and land management in the areas discussed. Each chapter begins with a detailed, up-to-date account of the ecology of the region (its climate, soils, vegetation, fauna and main ecological characteristics). This is followed by a history of land use, problems involved in its management, a review of current research and recommended land use practices. The common features of semi-arid ecosystems are brought together in a final section.

Download or read book Plant Growth Promoting Microorganisms of Arid Region written by Ritu Mawar and published by Springer Nature. This book was released on 2023-03-01 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book aims to focus on microbial diversity in arid lands and deserts versus specific microbial assemblages associated with plants. The book explains ecological drivers that shape this diversity, how plant-associated microbiomes are selected, and their biotechnological potential are discussed. Diversity and functional redundancy of these associated PGPM make them very active in supporting plant improvement, health and resistance to drought, salt and other stresses, and these dimensions will be explored in this book. Implementing proper biotechnological applications of the arid and desert-adapted PGPM constitutes a sizeable challenge, and the book attempts to take up that challenge and help researchers in this field to gain a detailed understanding of PGPM from arid ecosystems. This book serves as a handbook for research workers, teachers, postgraduate students and extension personnel, other development workers, and policy planners engaged in arid zone development.
