This book provides a succinct but comprehensive presentation of key geomorphological locations and topics including information about geomorphological heritage and maps to visit the most important sites. Apart from often being remarkably scenic, landscapes reveal stories that often can be traced back in time tens of million years and include unique events. This is particularly true for Ethiopia where spectacular examples of different landforms are present. Its geomorphology varies from highlands, marked by high volcanoes and incised by deep river gorges, to the rift valley lakes endorheic systems and the below sea level lowlands with characteristic landscapes which are unique in the world. Landscapes and Landforms of Ethiopia highlights all these topics including essential information about geology and tectonic framework, past and present climate, hydrology, geographical regions and long-term geomorphological history. It is a highly informative book, providing insight for readers with an interest in geography and geomorphology.
Understanding Ethiopia is a detailed description of Ethiopia’s geological story and enables non-specialist readers to share the author’s thrill at gaining a deeper insight into the processes which produced, and continue to shape, this amazing country. Ethiopia’s spectacular landscapes, ranging from mountains over 4500m high to salt plains 150m below sea level, are a reflection of the geological processes that formed the country. Indeed, its history and the historical sites, for which it is renowned, are largely determined by geology. Readers learn why and how Ethiopia’s geology is both unique and dynamic, as here the earth’s crust is in the process of breaking apart.
Two sections of EarthÕs crust meet to form the Great Rift Valley in the middle of Ethiopia. Bordering the valley are some of AfricaÕs most expansive highland areas, lending Ethiopia the nickname, Òthe roof of Africa.Ó Discover the diversity of landscapes, people, and wildlife in this informative title for young readers.
This book focuses on regions for which until now the geomorphology was very poorly studied and relatively unknown. Nevertheless, the landforms and landscapes of the Horn of Africa are highly attractive, diverse and in a few cases unique, since they span very different environments, from highland plateaus and mountains to lowlands (even below sea level) and coastlines with a high degree of diversity and from monsoon to arid climate conditions. The main topics addressed in the book include the links between the geological evolution and the current large scale geomorphology of the Horn of Africa; the large differences between the highlands and lowlands climate, river hydrology and their variation through time within a climate change perspective. This part of the world was home of the very first hominids. The landscape in which they lived and evolved throughout the Pleistocene is described in comparison with the arid and inhospitable, though immensely scenic, environment of today. Perennial and ephemeral rivers with very different morphology, processes, and hydrology drain the area, and, in combination with the past and recent uplift, substantially contributed to provide the region with peculiar landscapes and landforms. Long lasting weathering and erosion processes result in a typical inselberg landscape such as the Bur region, or the currently exposed flatland of old peneplain surfaces. Their changes through time, induced by both natural and anthropogenic factors, are addressed by a couple of case studies. Though the region has few inhabitants, they had to struggle to find their livelihood in a land that offers poor resources. This resulted in landscape change and land degradation. Examples of human impact on the landscape are presented at different scales. This book provides readers interested in geography and geomorphology with essential scientific and educational information on the Landscapes and Landforms of Eritrea, Djibouti and Somalia through simple, though scientifically, rigorous texts illustrated with several color maps and photos. One main prerogative of this book is therefore to give an insight into a region of the world where, for geographical and historical constraints, geomorphological investigation was very limited, thus enriching its intrinsic informative value.
Living Terraces is both an ethnographic and historical account of the terraces of Konso in southern Ethiopia. Terraced agricultural landscapes in Africa are remarkable feats of human engineering and social organization, enabling the conservation of soil and water and the cultivation of food. Indigenous terraced landscapes are all the morevaluable because they have been produced by the people themselves and maintained for several hundred years, evidencing a valuable degree of sustainability. Yet until this book, there have been few accounts of how such landscapesin Africa are produced and maintained over time. Taking a period of approximately a hundred years, Living Terraces is both an ethnography and history of the terraces of Konso in southern Ethiopia. It traces the way Konso agriculture and landscape has been produced and managed in close relationship with broader changes in Konso political and cultural lives. In shedding new light on the relationships between landscapes, livelihoods, culture and development, the book demonstrates the embeddedness of social institutions in areas of social, cultural, religious and political life, showing that social institutions cannot easily be abstracted, replicated or used instrumentallyfor development purposes. The result is a call for an approach to social institutions, so vital to development, which centralizes a study of culture, history and power in the analysis. ELIZABETH E.
