Download or read book Forest Development in Cold Climates written by John Alden and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: As forests decline in temperate and tropical climates, highly-developed countries and those striving for greater economic and social benefits are beginning to utilize marginal forests of high-latitude and mountainous regions for resources to satisfy human needs. The benefits of marginal forests range from purely aesthetic to providing resources for producing many goods and services demanded by a growing world population. Increased demands for forest resources and amenities and recent warming of high latitude climates have generated interest in reforestation and afforestation of marginal habitats in cold regions. Afforestation of treeless landscapes improves the environment for human habitation and provides for land use and economic prosperity. Trees are frequently planted in cold climates to rehabilitate denuded sites, for the amenity of homes and villages, and for wind shelter, recreation, agroforestry, and industrial uses. In addition, forests in cold climates reduce the albedo of the earth's surface in winter, and in summer they are small but significant long-lived sinks for atmospheric carbon dioxide. Finally, growth and reproductive success of forests at their geographic limits are sensitive indices of climatic change. As efforts to adapt forests to cold climates increase, however, new afforestation problems arise and old ones intensify. Austral, northern, and altitudinal tree limits are determined by many different factors. Current hypotheses for high-latitude tree limits are based on low growing-season temperatures that inhibit plant development and reproduction.

Download or read book Geographers written by Elizabeth Baigent and published by Bloomsbury Publishing. This book was released on 2019-12-26 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Women are the exclusive focus of the 38th volume of Geographers. For the first time in the serial's history, the entire volume is devoted to important work of distinguished female geographers, amply demonstrating how these scholars' professional lives enrich the discipline's history. It also illustrates how reading and writing their biographies not only expands our understanding of geography's past, but points to its more diverse future. The collection includes biographies of Doreen Massey, winner of geography's 'Nobel prize', the prix Vautrin-Lud, for her remarkable contribution to geography and neighbouring disciplines which discovered the importance of space through her work; Helen Wallis, geographer and historian of cartography who for many years had charge of the UK's foremost collection of maps; Alice Saunier-Seïté, who applied her geographical training and formidable energy to teaching and educational reform in France; Isabel Margarida André, who lived through a turbulent political period in her native Portugal and meticulously investigated its effect on women and political geography; and the many women who helped to create the UK's first Geography department - the University of Oxford's, School of Geography - including Fanny Herbertson, Nora MacMunn, Marjorie Sweeting, Mary Marshall, Barbara Kennedy and other women geographers who are memorialised in a group article.
