Book Synopsis Plants for Arid Lands by : G.E. Wickens

Download or read book Plants for Arid Lands written by G.E. Wickens. This book was released on 2012-12-06. 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.

Book Synopsis Plant Resources of Arid and Semiarid Lands by : J. R. Goodin

Download or read book Plant Resources of Arid and Semiarid Lands written by J. R. Goodin. This book was released on 2013-09-25. 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: This book deals with arid and semi-arid environments and their classification, and the physiological restraints and adaptations of plants to the environment. Further, it discusses economic botany and the needs and methods of conserving economic plants. A broad view is taken regarding the definition of economic plants, taking into account their value to the environment as well as to man and to livestock. The individual deserts and associated semi-arid regions are described in separate chapters, providing background information on the regional environments in terms of climate and major plant formations. The economic plants within these formations, their usages, geographical distribution together with their morphological and physiological adaptations are treated in detail.
