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 Mesquite written by Rodney W. Bovey and published by Texas A&M University Press. This book was released on 2016-09-30 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global problem or treasure? This question has accompanied the widespread and controversial mesquite tree wherever it grows and is studied around the world. In this comprehensive reference to the genus Prosopis, rangeland scientist Rodney Bovey has gathered and synthesized years of research in a book that reflects our current state of knowledge about the biology, morphology, and management of mesquite. Environmentally adaptive, the mesquite is considered by many to be an invasive or a pest species, and Bovey addresses the concerns about mesquite encroachment worldwide. But he also explains its ecological importance in the prevention of erosion and desertification and in providing food and habitat for wildlife. In addition, Bovey traces the uses of mesquite by humans and discusses the economics of growing and harvesting mesquite. A handy guide to the names, locations, distributions, habitat, structure, and uses of several species of mesquite is included in this benchmark publication for ecologists, range managers, biologists, landowners, and students of agriculture and ecosystem science.

Download or read book The Magnificent Mesquite written by Ken E. Rogers and published by University of Texas Press. This book was released on 2010-07-22 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive guide to the versatile mesquite tree covers its various species and many uses, from food to furniture to rangeland management. A reliable source of food and shelter even in the severest droughts, the mesquite tree sustained American Indians in the Southwest for centuries. Today, mesquite is popular for barbecuing, woodworking, furniture making, flooring, sculpture, jewelry, and food products ranging from honey to jelly and syrup. Even ranchers, who once fought to eradicate mesquite, have come to value its multiple uses on well-managed rangeland. In this accessible volume, one of the world's leading authorities on mesquite presents a wealth of information about its natural history and commercial, agricultural, and woodworking uses. Ken Rogers describes the life cycle, species, and wide distribution of the mesquite, which is native or naturalized not only in the Southwest and Mexico, but also in India, Africa, Australia, South America, and Hawaii. Rogers discusses the many consumer and woodworker uses of mesquite, even giving instructions for laying a mesquite wood floor and making mesquite bean jelly. He also looks into the ways that people are using mesquite in nature, from rangeland management in the Southwest to desertification prevention in arid countries.
Download or read book Silvopastoral Systems in Southern South America written by Pablo Luis Peri and published by Springer. This book was released on 2016-03-02 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

Download or read book Halophytes as a resource for livestock and for rehabilitation of degraded lands written by V. Squires and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desertification (land degradation in arid, semi-arid and dry sub-humid areas resulting mainly from adverse human impacts) is the main environmental problem of dry lands, which occupy more than 40 per cent of the total global land area. The phenomenon threatens about 3.6 billion hectares and currently affects the livelihood of about 900 million people. Thl! world is now losing annually about 1.5 million hectares of total irrigated lands (240 million hectares) due mostly to salinization, mainly in drylands. Salt affected soils are widely distributed throughout the arid and semi-arid regions, and particularly severe in China (7 million ha), India (20 million ha), Pakistan (3.2 million ha), USA (5.2 million ha), as well as Near East, southern Europe and elsewhere. Demands on production have increased the pressure on existing productive land and moved the limits of production onto increasingly marginal lands. Wise land-use practices have yet to be developed for such conditions. The Executive Director of UNEP reported to the Governing Council in February 1992 concerning the "Status of Desertification and Implementation of the United Nations Plan of Action to Comtat Desertification (PACD)". The Report concludes that major efforts to implement the PACD had gJne into supporting measures rather than concrete corrective field operations. Little evidence of progrl!ss was found in irrigated croplands, rainfed croplands or rangelands. It was recommended that every piece of land should be used in keeping with its ecological characteristics, natural capabilities and constraints.

Download or read book Ecological Systems of the Geobiosphere written by Heinrich Walter and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Volume 1 of this four-volume series, ecological problems of a general nature were discussed from a global point of view. Familiarity with this is essential for a full understanding of the more specialized treatment in this and subsequent volumes, for no similar approach is to be found in other ecological handbooks for beginners. This present volume deals in detail with the special ecological relation ships of the tropical and subtropical zonobiomes I to III. Most ecologists proceed from the basis of their experience in the temperate zones of the northern hemisphere. As a result, many ecological writings show a certain one-sidedness and there is a danger that generalizations made will not be broadly applicable. To avoid this, particular emphasis is laid, in this vol urne, on the special ecological features and the characteristics of the trop ical and subtropical regions. More specifically, we deal not only with the relationship of the euclimatope to zonal soils and zonal vegetation, but also pay attention to azonal conditions shown in pedobiomes and in the altitudinal belts of mountains, the orobiomes. In this and the subsequent volumes the same simple scheme is followed in treating each zonobiome: 1. climate; 2. soils; 3. producers; 4. consum ers; 5. decomposers; 6. ecosystems; 7. sub division into biomes; 8. oro biomes; 9. pedobiomes and 10. zonoecotones. Where it has appeared expedient, however, we have occasionally deviated from this scheme (see Deserts D, F, G and H).

Download or read book Tropical Legumes written by National Research Council and published by The Minerva Group, Inc.. This book was released on 2002-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This National Academy of Sciences report describes plants of the family Leguminosae, all of them greatly underexploited. Some are extensively used in one part of the world but unknown elsewhere; others are virtually unknown to science but have particular attributes that suggest they could become major crops in the future; a few are already widespread but their possibilities are not yet fully realized.Most of the plants described in this book have the capacity to provide their own nitrogenous fertilizer through bacteria that live in nodules on their roots; the bacteria chemically convert nitrogen gas from the air into soluble compounds that the plant can absorb and utilize. As a result, legumes generally require no additional nitrogenous fertilizer for average growth. This is advantageous because commercial nitrogenous fertilizers are now extremely expensive for peasant farmers. This report demonstrates how farmers in developing countries, by using leguminous plants, can grow useful crops while avoiding that expense. However, the plants to be discussed here should be seen as complements to, not as substitutes for, conventional tropical crops.
Download or read book Step Wise Protocols for Somatic Embryogenesis of Important Woody Plants written by Shri Mohan Jain and published by Springer. This book was released on 2018-05-30 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: World population is increasing at an alarming rate and this has resulted in increasing tremendously the demand for tree products such as wood for construction materials, fuel and paper, fruits, oils and medicines etc. This has put immense pressure on the world’s supplies of trees and raw material to industry and will continue to do so as long as human population continues to grow. Also, the quality of human diet, especially nutritional components, is adversely affected due to limited genetic improvement of most of fruit trees. Thus there is an immediate need to increase productivity of trees. Improvement has been made through conventional breeding methods, however, conventional breeding is very slow due to long life cycle of trees. A basic strategy in tree improvement is to capture genetic gain through clonal propagation. Clonal propagation via organogenesis is being used for the production of selected elite individual trees. However, the methods are labour intensive, costly, and produce low volumes. Genetic gain can now be captured through somatic embryogenesis. Formation of embryos from somatic cells by a process resembling zygotic embryogenesis is one of the most important features of plants. In 1958, Reinert in Germany and Steward in USA independently reported somatic embryogenesis in carrot cultures. Since then, tremendous progress in somatic embryogenesis of woody and non-woody plants has taken place. It offers a potentially large-scale propagation system for superior clones.
