Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
Области покровного и горного оледенения находятся в центре внимания наук о Земле. Это связано с рядом научных, экономических и политических факторов. В частности, одной из важнейших задач государства является обеспечение развития территорий Арктики – зоны стратегических интересов России. Не менее важной геополитической задачей является обеспечение присутствия Российской Федерации в Антарктическом регионе. Серьезным политическим инструментом становится доступ к источникам пресной воды, которыми являются горные ледники.
Arid environments may not be the most hospitable places n Earth, but the 30 % or more of the global land surface that they cover does support an ever-growing human population and has fascinated travellers, explorers and scientists for centuries. Early geomorphological studies were frequently carried out indirectly, sometimes even unwittingly, by those whose main purpose and motives lay elsewhere: inevitably, but with some notable exceptions, their accounts were descriptive and unscientific. Some would even argue that these traits persisted and dominated desert geomorphological studies well into the second half of this century.
Along with storms, floods, earthquakes and volcanic eruptions, landslides are one of the most severe natural hazards. Even though they cause fewer victims than other hazards, landslides are responsible for huge economic damage around the world, with losses of hundreds of millions of Euros per year. In addition, differently from other hazards, even small magnitude events represent a serious threat, deeply affecting transportation corridors and disrupting movements of men and goods. Finally, landslides can cause strong geomorphological modifications inducing permanent changes in the landscape.
Earth surface processes, landforms, and sediment deposits are intimately related – involving erosion of rocks, generation of sediment, and transport and deposition of sediment through various Earth surface environments. These processes, and the deposits and landforms that they generate, have a fundamental bearing on engineering, environmental and public safety issues; on recovery of economic resources; and on our understanding of Earth history.

La acogida que tuvieron el libro Geomorfoiogía Climática (2001) y su traducción al inglés ligeramente ampliada, Climatic Geomorphology (2005), nos ha proporcionado el ánimo necesario para afrontar la redacción de un libro de carácter general más amplio que aborde las diferentes formas del relieve del planeta Tierra y de los procesos responsables de su génesis. El estudio de las morfologías, algunas de ellas generadas en tiempos geológicos pretéritos bajo condiciones ambientales muy diferentes a las actuales, nos permite reconstruir la evolución del relieve e inferir cambios ambientales en los que han podido intervenir el medio geológico, el clima o la actividad humana.
Вопросы изучения природных явлений и одновременно проблема охраны окружающей среды становятся все более актуальными. Настало время выработать правильные критерии природопользования. Эта задача может решаться лишь при высоком уровне изучения природных явлений, в том числе и таких динамичных комплексов, как морские берега, развитие которых протекает при исключительно сложном взаимодействии разнообразных процессов.
Настоящая монография написана коллективом авторов сотрудников Воронежского университета. В работе рассматриваются физико-географические осооенности меловых ландшафтов на территории юго-запада Воронежской области. Кроме обзора отдельных компонентов природы (геологии, почв, растительности и т. д.) в книге также дается характеристика наиболее распространенных природных комплексов (типов местности, урочищ, склоновых ландшафтов и др.) этого района. Значительное место уделено во просам охфаны природы и ее рациональному использованию. Книга рассчитана на широкий круг читателей — научных работников, учителей, студентов, учащихся старших классов, краеведов и туристов.
Landforms and landscapes vary enormously across the Earth, from high mountains to endless plains. At a smaller scale, nature often surprises us creating shapes which look improbable. Many physical landscapes are so immensely beautiful that they received the highest possible recognition—they hold the status of World Heritage properties. Apart from often being immensely scenic, landscapes tell stories that not uncommonly can be traced back in time for tens of millions of years and include unique events. In addition, many landscapes owe their appearance and harmony not solely to the natural forces. For centuries, and even millennia, they have been shaped by humans who have modified hillslopes, river courses, and coastlines, and erected structures which often blend with the natural landforms to form inseparable entities. These landscapes are studied by geomorphology—‘the science of scenery’—a part of Earth Sciences that focuses on landforms, their assemblages, surface, and subsurface processes that molded them in the past and that change them today. To show the importance of geomorphology in understanding the landscape, and to present the beauty and diversity of the geomorphological sceneries across the world, we have launched a book series World Geomorphological Landscapes. It aims to be a scientific library of monographs that present and explain physical landscapes, focusing on both representative and uniquely spectacular examples. Each book will contain details on geomorphology of a particular country or a geographically coherent region. This volume presents the geomorphology of Brazil, a big country with a multitude of spectacular landscapes, from the very well known—such as the steep-sided domes of Rio de Janeiro, Iguazu Falls, or majestic rivers of the Amazonian Lowland—to many hidden gems scattered across the Brazilian Shield. For such a vast and varied territory to make a selection of case studies must have been an arduous task, so inevitably they present only a small fraction of what Brazil has to offer in terms of geomorphological sceneries to enjoy. To discover and learn more, go to Brazil! This would be an unforgettable geomorphological experience. The World Geomorphological Landscapes series is produced under the scientific patronage of the International Association of Geomorphologists (IAG)—a society that brings together geomorphologists from all over the world. The IAG was established in 1989 and is an independent scientific association affiliated with the International Geographical Union (IGU) and the International Union of Geological Sciences (IUGS). Among its main aims are to promote geomorphology and to foster dissemination of geomorphological knowledge. I believe that this lavishly illustrated series, which sticks to the scientific rigor, is the most appropriate means to fulfill these aims and to serve the geoscientific community. To this end, my great thanks go to the editors of this volume—Prof. Bianca Carvalho Vieira as the senior editor, and Profs. André Augusto Rodrigues Salgado and Leonardo José Cordeiro Santos as co-editors. <...>
