Available in PDF, EPUB and Kindle. Book excerpt: The increasing world population is already causing intensive pressure on the most productive areas of the earth's surface. Hopes of improved living standards, if realised, will increase the pressure still further. The need to make better use of less productive areas thus becomes an urgent priority for human endeavour. In this respect, the arid and semi-arid regions of the world, occupying about 11,000 million acres or 4,500 million hectares, roughly one third of the tota11and surface, pose a constant challenge to man's technological skill. Though the possibilities of economic use of the real deserts are inherently limited, there remain vast areas with less extreme conditions where sustained research is capable of yielding substantial gains in pro ductivity. The problem is so large that it can be solved only by the coordinated efforts of workers in many countries and many disciplines. Forestry has a special part to play, not only for its potential value for wood production but still more for the beneficial effects of shelter from desiccating winds which so commonly accompany arid conditions. Mr. KA UL is to be congratulated on his initiative to pool the results of research on afforestation in arid zones in many parts of the world, and to present them in a single volume in the form of separate monographs.

This book was released on 2013-04-17 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: A shortage of water exists, not only in the arid regions of the world, but even in some moderately humid climates. This situation is a consequence of water require ments for agriculture and industry in amounts greater than the natural surplus. Even in Europe there is increased anxiety over the state of water reserves, and shortages are forecast for the near future if industry continues to expand. During the past 50 years in the United States, water use has increased about twice as fast as the rate of population growth, and shortages have already appeared in some places. The need to conserve declining water resources which has become apparent over the last few decades has led several investigators to conclude that plants with a high rate of transpiration endanger water resources, and the growth of such plants must not be encouraged. Some think that trees withdraw more water from the soil than other plant species and evaporate it excessively through the stomata of leaves. THORNTHWAITE and HARE (1955) explained transpiration on the same thermo dynamic basis as evaporation, and calculated its rate, using DALTON'S law or modifications thereof. In spite ofthe many past and present investigations into the problems of transpiration, the biological aspects of this essential process is still poorly understood.
Download or read book Trees forests and land use in drylands the first global assessment written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-11-29 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drylands cover 41 percent of the Earth's land surface. This publication presents the results of the first global assessment of trees, forests and land use in these lands. The assessment breaks new methodological ground: it relies on the visual interpreation of freely available satellite images, carried out by more than 200 experts in a series of regional workshops. Using a tool called Open Foris ollect Earth, developed by FAO in collaboration with Google, participants gathered and analysed information for mrore than 200 000 sample plots worldwide. For each region, the report summarizes the distribution of forests, other wooded land and other land uses including grasslands, croplands, built-up areas and barren land, across all drylands and by aridity zone. It also estimates tree canopy cover, shrub cover, forest type and presence of trees outside forest. Indicatng that the global drylands contain more than one-quarter of the world's forest area, and that trees are present on 31 percent of the world's dryland area, the report provides a baseline for future monitoring and will support countries in their efforts to identify appropriate investments for the restoration and sustainable management of drylands.

Download or read book Forests And Forest Plants Volume III written by John N. Owens and published by EOLSS Publications. This book was released on 2009-02-24 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests and Forest Plants is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Forests are an essential part of Earth's life support systems. Forest resources are essential for humankind. They provide both vital goods and services. They provide food, fuel, shelter, soil and water protection, and filter the air we breathe. This publication on Forest and Forest Plants provides the user with such information as to create an awareness of the value of our forestlands and the products and environmental services they provide. The three volumes on Forests and Forest Plants are organized starting with first the necessity of : the World's Forest Resources – including classification and distribution of forest, urban forestry and agroforestry; Important Tree Species including trees in reclamation and arid zone forestry; Forests and Forest Products including wood and non word products; the Role of Forests in the Biosphere – preserving biological diversity, functions in the hydrological cycle, etc.; and Conservation and Breeding of Forest Trees – what is being done to improve our forest resources - silviculture, tree nurseries, and forest protection. The theme Forest and Forest Plants has led to the conclusion that there are substantial difficulties in matching environmental concerns and sustainability with an ever-increasing world population. Thus there is a tension between maximizing for food, wood and production on the one hand and implementing sustainable development and environmental protection on the other. These three volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.
Download or read book Afforestation Reforestation and Forest Restoration in Arid and Semi arid Tropics written by Panna Ram Siyag and published by Springer Science & Business Media. This book was released on 2013-09-24 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a comprehensive manual of practice for execution of afforestation and tree planting programmes in arid and semi-arid tropics. It includes a compact running account of the technology of afforestation and the relevant principles and practices in management of afforestation projects. It provides a wide range of structured information and a number of model designs which can be gainfully put to use by the field level supervisors as also by the managers concerned with planning and control of such projects. Written by a practising specialist, the book is invaluable for anyone concerned with the practice of afforestation and tree planting, be he a tree hobbyist or a school teacher, a professional forester or a senior policy maker in government, an industrialist or a philanthropist, an environmental activist or a member of a community service organization.
