"The mile-deep gorge made by the Blue Nile as it flows out of the highlands of North West Ethiopa into the broad plains of the Sudan is one of the greatest natural features in the world. It remained virtually unexplored until 1968. That summer an expedition supported by the Army, The Daily Telegraph and the Royal Geographical Society set out to investigate this gorge. It also aimed to navigate 500 miles of the crocodile-infested river - known in Ethiopa as the Great Abbai - 200 miles of which had not been visited by Europeans, except at occasional fording places." "The climax of the expedition, the penetration of the Northern gorge, was unhappily marked by the death of an expedition member by drowning, and by two attacks by bandits. In these harsh conditions a group of scientists - mainly zoologists - were able to carry out a valuable investigation of the area."--BOOK JACKET.
What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzóska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of “The Nile: Biology of an Ancient River”. Thirty-seven authors have taken up the challenge, and have written the “new” book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzóska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.

The view encompasses more than 2000 kilometers from the river junction in the lower part of the picture to just below the Qena-Luxor bend, at the left upper end. The photograph was taken before the Aswan High Dam basin began to rise. The Red Sea and Saudi Arabia and the Ethiopian Highlands form the background.

A big library could be filled by books on this river devoted to exploration and discovery, human history and hydrology. None has so far been written on the biology of the whole river system.

This book tells briefly about the pioneer missionaries effort in the previous Welega province in Western-Ethiopia, and then about the untiring Ethiopian pastor and bible translator, Onesimus Nezib (1856- 1931). However the author’s main intention with the writing is to recall from personal experiences during serving terms in the same province in close co-operation with national colleagues, and with a special focus on health care. In particular he writes about the work among the Gumuz people who are living along the Blue Nile River – also he records from his experiences among the Berta people, another lowland group. The health service was for a period carried on as an ambulatory work, but after some time permanent clinics were established. The book has a lot of photos which will introduce these lowland people and show the health care activities and other branches of the work of the church. One of the author’s working-terms was at a major clinic on the highland where the Oromo people are living, and the book refers to quite many experiences from there. It is also recalled from the overthrown of Emperor Haile Selassie in September 1974, and about the difficult time which followed during the reign of the communist regime until it was defeated at spring 1991. After a shorter time with some tumults between two liberation organizations the situation became normalized and with good living and working conditions.
Ethiopia is one of the oldest countries in the world. This book traces the country's expansion southward during medieval times, its resistance to Muslim invasion, and, under energetic leaders, its defense of its independence during the European scramble for Africa. The author is concerned not only with kings, princes and politicians but also includes insights on daily life, art, architecture, religion, culture, customs and observations by travelers.
Ethiopia is clearly one of the most important countries in Africa. First of all, with about 75 million people, it is the third most populous country in Africa. Second, it is very strategically located, in the Horn of Africa and bordering Eritrea, Sudan, Kenya, and Somalia, with some of whom it has touchy and sometimes worse relations. Yet, its capital – Addis Ababa – is the headquarters of the African Union, the prime meeting place for Africa’s leaders. So, if things went poorly in Ethiopia, this would not be good for Africa, and for a long time this was the case, with internal disruption rife, until it was literally suppressed under the strong rule of the recently deceased Meles Zenawi. The Historical Dictionary of Ethiopia, Second Edition covers the history of Ethiopia through a chronology, an introductory essay, appendixes, and an extensive bibliography. The dictionary section has several hundred cross-referenced entries on important personalities, politics, economy, foreign relations, religion, and culture. This book is an excellent access point for students, researchers, and anyone wanting to know more about Ethiopia.
Ethiopia is one of the world's oldest countries; its Rift Valley may be the location where the ancestors of humankind originated more than four million years ago. With a population of 67 million people today, it is the third most populous country on the African continent after Nigeria and Egypt. It is the source of 86 percent of the water reaching the Aswan Dam in Egypt, most of it carried by the amazing Blue Nile. Ethiopia offers major historical sites such as the pre-Christian palace at Yeha, the stele and tombs of the old Kingdom of Axum, and the rock-carved churches of Lalibela. For anyone interested in Ethiopia, this historical dictionary, through its individual and carefully cross-referenced entries, captures the importance and intrigue of this truly significant African nation. Historical Dictionary of Ethiopia appeals to all levels of readers, providing entries for each of Ethiopia's 85 ethnic groups and covering a broad range of cultural, political, and economic topics. Readers interested in the cultural aspects or who are planning to visit Ethiopia will find a wealth of entries on art, literature, handicrafts, music, dance, bird life, geography, and historic tourist sites. Practitioners in government and non-governmental organizations will find entries on pressing economic, social, and political issues such as HIV/AIDS, female circumcision , debt, human rights, and the environment. The important historical role of missionaries and the combination of conflict and cooperation between Christians and Muslims in the region are also issues reviewed. And, finally, many of the entries highlight relations between Ethiopia and her neighbors-Eritrea, Somalia, Somaliland, Djibouti, Kenya, and Sudan. In the bibliography, considerable emphasis has been placed on including both new and old materials covering all facets of Ethiopia, organized for easy identification by areas of major interest.
