This book is an attempt to compile and integrate the information documented by many botanists, both Egyptians and others, about the vegetation of Egypt. The first treatise on the flora of Egypt, by Petrus Forsskäl, was published in 1775. Records of the Egyptian flora made during the Napoleonic expedition to Egypt (1778-1801) were provided by AR. Delile from 1809 to 1812 (Kassas, 1981). The early beginning of ecological studies of the vegetation of Egypt extended to the mid-nineteenth century. Two traditions may be re cognized. The first was general exploration and survey, for which one name is symbolic: Georges-Auguste Schweinfurth (1836-1925), a German scientist and explorer who lived in Egypt from 1863 to 1914. The second tradition was ecophysiological to explain the plant life in the dry desert. The work of G. Volkens (1887) remains a classic on xerophytism. These two traditions were maintained and expanded in further phases of ecological development associated with the es tablishment of the Egyptian University in 1925 (now the University the Swedish Gunnar of Cairo). The first professor of botany was Täckholm (1925-1929). He died young, and his wife Vivi Täckholm devoted her life to studying the flora of Egypt and gave leadership and inspiration to plant taxonomists in Egypt for some 50 years. She died in 1978. The second professor of botany in Egypt was F. W. Oliver (1929- 1932) followed by the British ecologist F. J. Lewis (1935-1947).

The vegetation in Wadi El Gemal National Park in Egypt's Eastern Desert is more diverse than might first be expected, but even more surprising is the relationship that the desert dwellers continue to have with the plant life in their habitat, despite the increasing modernization of their world. As a ranger in the park, Tamer Mahmoud quickly realized the importance of surveying, identifying, and documenting the indigenous plants, and recording the information he compiled from interviews with the local community about how they use the plants for food, healing, animal fodder, and fuel. The result is this detailed and colorful guide, which includes photographs of each plant, the scientific name and local name in Arabic and English, and information on location, distribution, uses, and ecology. A glossary, bibliography, visitors' information section and distribution maps make this a comprehensive reference work that will interest visitors, scientists, anyone interested in the flora of arid areas, and even anthropologists.

The position of Egypt as a cross-road territory between the Middle East and Africa has attracted the attention of naturalists and explorers for many centuries. There have been many thousands of published studies relating to aspects of the ecological and botanical patterns of Egyptian vegetation, but this work draws this information together.

Usually authors write introductions for their books, although they know that not many readers will read it. Despite this, authors insist on writing an introduction and no publisher will publish a book without one. I would like to inform my dear readers that I have spent almost all of the first quarter of my life in a village in the Nile Delta, 65 km north of Cairo. The everyday scenery there was the beautiful green landscape dissected with canals full of running water. All of these were bordered with the huge sycamore, mulberry and acacia trees. The desert was something unknown to me at that time, except for the very basic information given in geography books, which explained that the desert is a place without water or cultiva tion. Some of my ideas about the desert came to me from the stories in the history of Islam and the desert lands where Islam originated. My real attraction to the desert developed in the last year of my under graduate studies. This was during the field courses in Ecology (Prof. A.M.

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.

Deserts are unique ecosystems with their own biotic and abiotic components, and are often rich in renewable natural resources, the appropriate management of which can contribute significantly to the sustainable management of desert regions for the welfare of the people. Yet while there are many books on the flora of the countries fringing the important desert countries of the Mediterranean and Red Seas, there or few books reporting on their ecophysiology and vegetation ecology. This book presents the vegetation types of the African and Asian countries of the Mediterranean and Red Sea coastal regions, and discusses the ecological threats and economic applications of these critical resources. In particular, it examines the relationships between climate and vegetation, and discusses these within the context of desertification, agro-industrial applications, ecotourism and sustainable development. The book will provide a valuable reference for researchers and graduate students involved in plant ecology, biogeography, economic botany and environmental management in the Afro-Asian Mediterranean and Red Sea coastal regions, as well as other desert regions around the world.
