Book Description
Pichi Sermolli’s work with his more than 2750 collections of plants from nearly 150 localities on the Lake Tana expedition in Ethiopia in 1937 was interrupted by World War II, but completed in 1947 at the Royal Botanic Gardens, Kew, and the British Museum (Natural History), UK. It resulted in preliminary accounts of the vegetation published 1938-40 and a taxonomically arranged account in 1951, all in Italian. Pichi Sermolli’s observations are difficult to locate due to the imperfect maps of the time, but in this book the authors have reconstructed the sequence of the collections, georeferenced the localities, and updated the identifications of the species. By reconstructing Pichi Sermolli’s observations, it is possible to draw conclusions about the vegetation and compare with a recent model of the vegetation of Ethiopia. According to this, the vegetation of the Lake Tana Basin was a complex mosaic of woodland, scrub, forest, farmland and lake shore vegetation now difficult to interpret in detail. Pichi Sermolli’s study of the vegetation in the Semien Mountains demonstrated for the first time the zonation of Ericaceous woodland and Afroalpine vegetation, within which he distinguished Carex monostachya bogs, Afroalpine grasslands with Lobelia rhynchopetalum, and stony and rocky Afroalpine vegetation. This book interprets Pichi Sermolli’s observations in English and compares them with modern knowledge of the region, partly obtained by the present authors’ own field work. It demonstrates how Pichi Sermolli’s studies form a valuable contribution to the understanding of the Ethiopian flora and vegetation.

Book Description
This book covers biodiversity conservation under special consideration of the challenges in the global south with particular attention being paid to consider the existing conservation challenges in relation to the study area in Ethiopia. Key issues are addressed, such as the current and future threats to plant biodiversity in Ethiopia, as well as the single large or several small conservation approaches and which approach is feasible for Ethiopia. Furthermore, an innovative approach was developed that enhances ecological connectivity and promotes ecological restoration through community involvement. The book also covers why a systematic conservation planning approach is important and should be used in new protected area establishments, and also looks at the trends of plant ecology research over the past five decades, revealing research gaps and suggesting future research topics. Despite its focus on Ethiopian plant diversity, abundant examples were used from different continents making this book attractive to global readers. It will be of interest for policy- and decision-makers in the conservation sector, researchers interested in biodiversity, climate change, conservation and sustainable use of natural resources, and would be a valuable resource for university students.

Book Description
One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and conservation in Ethiopia, and the evaluation and utilization of Ethiopian genetic resources. A broad range of food and feed crops and plants of medicinal and industrial importance are discussed, both at a national and international level. A brief account of conservation strategies and gene bank problems unique to Ethiopia is also given. The importance of Ethiopia's plant genetic resources to world agriculture has been demonstrated on more than one occasion. Plant breeders, geneticists, and botanists throughout the world will, therefore, find this unique book a valuable source of information and an essential reference work.

Book Description
The book covers 101 families (gymnosperms: 1; dicots: 79; monocots: 21), close to 300 genera and 545 species recorded from the Simen and surroundings. Brief descriptions are provided for all taxa, and keys are generally included if a family is represented by 3 or more taxa. The arrangement of families (and genera) follows the Flora of Ethiopia and Eritrea, making it easy to cross-check for more detailed information.

Book Description
"A new map of the potential vegetation types of Ethiopia has been produced at the scale of 1:2,000,000. It is published here as an atlas with 29 map plates. The map shows the distribution of twelve potential vegetation types that can be mapped using environmental parameters and GIS methodology. In the accompanying text these vegetation types have been described and further divided into a number of subtypes. The types and subtypes are: (1) Desert and semi-desert scrubland. (2) Acacia-Commiphora woodland and bushland (with the subtypes (2a) Acacia-Commiphora woodland and bushland proper and (2b) Acacia wooded grassland of the Rift Valley). (3) Wooded grassland of the western Gambela region. (4) Combretum-Terminalia woodland and wooded grassland. (5) Dry evergreen Afromontane forest and grassland complex (with the subtypes (5a) Undifferentiated Afromontane forest, (5b) Dry single-dominant Afromontane forest of the Ethiopian highlands, (5c) Afromontane woodland, wooded grassland and grassland, (5d) Transition between Afromontane vegetation and Acacia-Commiphora bushland on the Eastern escarpment). (6) Moist evergreen Afromontane forest (with the subtypes (6a) Primary or mature secondary moist evergreen Afromontane forest, and (6b) Edges of moist evergreen Afromontane forest, bushland, woodland and wooded grassland). (7) Transitional rain forest. (8) Ericaceous belt. (8) Afroalpine belt. (10) Riverine vegetation. (11) Fresh-water lakes, etc. (with the subtypes (11a) Fresh-water lake vegetation (open water) and (11b) Freshwater marshes and swamps, floodplains and lake shore vegetation). (12) Salt lakes, etc. (with the subtypes (12a) Salt lake vegetation (open water) and (12b) Salt pans, saline brackish and intermittent wetlands and salt-lake shore vegetation)"--Synopsis.

Book Description
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.

Book Description
This book, with contributions from leading academics - and including reviews and case studies from Ethiopian Church forests - provides a valuable reference for advanced students and researchers interested in forest and other natural resource management, ecology and ecosystem services as well as restoration options. The book addresses various aspects including a general overview of Ethiopian church forests, the present role and future challenges of church forests. It also discusses their structure and diversity in the context of sustainability and discusses restoration options for surrounding landscapes, under consideration of the circumstances of the land and the needs of surrounding communities. The intended readership includes natural resource professionals in general as well as forestry professionals in particular (practitioners, policymakers, educators and researchers). The book will provide the reader with a good foundation for understanding Ethiopian forest resources and restoration options of degraded landscape.

Book Description
This book presents the results of the biodiversity hotspots - those discrete, biogeographic regions that are known to hold at least 1,500 plants as endemics and that have lost at least 70% of their primary native vegetation.
