Download or read book Ecophysiology of Economic Plants in Arid and Semi Arid Lands written by Gerald E. Wickens and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 348 pages. Available in PDF, EPUB and Kindle. 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.

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 Plant Resources of Arid and Semiarid Lands written by J. R. Goodin and published by Academic Press. This book was released on 2013-09-25 with total page 353 pages. 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 Culture Ecology and Economy of Fire Management in North Australian Savannas written by Jeremy Russell-Smith and published by CSIRO PUBLISHING. This book was released on 2009-10-26 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This engaging volume explores the management of fire in one of the world’s most flammable landscapes: Australia’s tropical savannas, where on average 18% of the landscape is burned annually. Impacts have been particularly severe in the Arnhem Land Plateau, a centre of plant and animal diversity on Indigenous land. Culture, Ecology and Economy of Fire Management in North Australian Savannas documents a remarkable collaboration between Arnhem Land’s traditional landowners and the scientific community to arrest a potentially catastrophic fire-driven decline in the natural and cultural assets of the region – not by excluding fire, but by using it better through restoration of Indigenous control over burning. This multi-disciplinary treatment encompasses the history of fire use in the savannas, the post-settlement changes that altered fire patterns, the personal histories of a small number of people who lived most of their lives on the plateau and, critically, their deep knowledge of fire and how to apply it to care for country. Uniquely, it shows how such knowledge and commitment can be deployed in conjunction with rigorous formal scientific analysis, advanced technology, new cross-cultural institutions and the emerging carbon economy to build partnerships for controlling fire at scales that were, until this demonstration, thought beyond effective intervention.

Download or read book Uses and Abuses of Plant Derived Smoke written by Marcello Pennacchio and published by Oxford University Press. This book was released on 2010-07-15 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants provide the food, shelter, medicines, and biomass that underlie sustainable life. One of the earliest and often overlooked uses of plants is the production of smoke, dating to the time of early hominid species. Plant-derived smoke has had an enormous socio-economic impact throughout human history, being burned for medicinal and recreational purposes, magico-religious ceremonies, pest control, food preservation, and flavoring, perfumes, and incense. This illustrated global compendium documents and describes approximately 2,000 global uses for over 1,400 plant species. The Uses and Abuses of Plant-Derived Smoke is accessibly written and provides a wealth of information on human uses for smoke. Divided into nine main categories of use, the compendium lists plant-derived smoke's medicinal, historical, ceremonial, ritual and recreational uses. Plant use in the production of incense and to preserve and flavor foods and beverages is also included. Each entry includes full binomial names and family, an identification of the person who named the plant, as well as numerous references to other scholarly texts. Of particular interest will be plants such as Tobacco (Nicotiana tabaccum), Boswellia spp (frankincense), and Datura stramonium (smoked as a treatment for asthma all over the world), all of which are described in great detail.
