Download or read book Roman Foodprints at Berenike written by Rene T. J. Cappers and published by Cotsen Institute of Archaeology Press. This book was released on 2006-12-31 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the Graeco-Roman period, Berenike served as a gateway to the outside world together with Myos Hormos. Commodities were imported from Africa south of the Sahara, Arabia, and India into the Greek and Roman Empire, the importance of both harbors evidenced by several contemporary sources. Between 1994 and 2002, eight excavation seasons were conducted at Berenike by the University of Delaware and Leiden University, the Netherlands. This book presents the results of the archaeobotanical research of the Roman deposits. It is shown that the study of a transit port such as Berenike, located at the southeastern fringe of the Roman Empire, is highly effective in producing new information on the import of all kinds of luxury items. In addition to the huge quantities of black pepper, plant remains of more than 60 cultivated plant species could be evidenced, several of them for the first time in an archaeobotanical context. For each plant species detailed information on its (possible) origin, its use, its preservation qualities, and the Egyptian subfossil record is provided. The interpretation of the cultivated plants, including the possibilities of cultivation in Berenike proper, is supported by ethnoarchaeobotanical research that has been conducted over the years. The reconstruction of the former environment is based on the many wild plant species that were found in Berenike and the study of the present desert vegetation.
Download or read book The Public Health Effects of Food Deserts written by National Research Council and published by National Academies Press. This book was released on 2009-07-02 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, people living in low-income neighborhoods frequently do not have access to affordable healthy food venues, such as supermarkets. Instead, those living in "food deserts" must rely on convenience stores and small neighborhood stores that offer few, if any, healthy food choices, such as fruits and vegetables. The Institute of Medicine (IOM) and National Research Council (NRC) convened a two-day workshop on January 26-27, 2009, to provide input into a Congressionally-mandated food deserts study by the U.S. Department of Agriculture's Economic Research Service. The workshop, summarized in this volume, provided a forum in which to discuss the public health effects of food deserts.
Download or read book The Desert Experience in Israel written by A. Paul Hare and published by University Press of America. This book was released on 2009-09-29 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Desert Experience in Israel shares the responses of settlers, artists, poets, scientists, and educators who lived near the Blaustein Institute in the Negev Desert of Israel as they answer the question, 'What difference has living in the desert year round made in your work?' The book begins with a reprint of David Ben-Gurion's call for settlement and science in the desert. This is followed by an account of life in early kibbutzim, a discussion of the meaning of the term 'desert,' accounts of religion in the desert, and the relationship of the desert experience to art, theatre, literature, poetry, sculpture, and the use of color categories by the Bedouin. Accounts of research on solar energy, fossil fuel, water, microalgae, runoff agriculture, fish, and architecture are followed by desert-related activities in the high school, field school, and research institute.
Download or read book One Day in the Desert written by Anna Keener and published by Rowman & Littlefield. This book was released on 2017-11-15 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mariana is a third grader living in Las Cruces, New Mexico at the northern fringe of the Chihuahuan Desert. One day her class visits Chihuahuan Desert Nature Park to hike to the top of an extinct volcano and see the plant and animal life that is special to this desert. Led by Dr. Whitford, the nature park scientist, the children are challenged to find as many signs of animals living along the trail as they can. Mariana is amazed at all the life around her that was difficult to see at first glance. Adapting to the desert environment, many animals were camouflaged or sought shelter from the sun in burrows. At last atop the volcano, Dr. Whitford tells the children that “This is a great example of an ecosystem that has shifted.” Once grassland, the landscape is now mostly covered in shrubs like creosote bush and mesquite. Suddenly a storm comes up with little warning, and the children rush back to their bus. As the rain subsides the bus driver delivers the unwelcome news that the bus will have to be pulled out of the now muddy road. While waiting for help the children get out of the bus and head for a nearby Playa, a special kind of shallow lake that is formed after a heavy rain. As Mariana wades through the Playa she notices small animals in the water, and scoops one up. Dr. Whitford identifies it as a tadpole shrimp, animals that hatch only when water fills the lakes. At last the bus is pulled out of the mud by a rancher’s tractor, and Mariana returns home to write to her friends about her day in the desert.

Download or read book Survival Strategies of Annual Desert Plants written by Yitzchak Gutterman and published by Springer Science & Business Media. This book was released on 2002-08-28 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.
Download or read book The History of the Peoples of the Eastern Desert written by Hans Barnard and published by Cotsen Institute of Archaeology Press. This book was released on 2012-12-31 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last quarter century has seen extensive research on the ports of the Red Sea coast of Egypt, the road systems connecting them to the Nile, and the mines and quarries in the region. Missing has been a systematic study of the peoples of the Eastern Desert--the area between the Red Sea and the Nile Valley--in whose territories these ports, roads, mines, and quarries were located. The historical overview of the Eastern Desert in the shape of a roughly chronological narrative presented in this book fills that gap. The multidisciplinary perspective focuses on the long-term history of the region. The extensive range of topics addressed includes specific historical periods, natural resources, nomadic survival strategies, ancient textual data, and the interaction between Christian hermits and their neighbors. The breadth of perspective does not sacrifice depth, for all authors deal in some detail with the specifics of their subject matter. As a whole, this collection provides an outline of the history and sociology of the Eastern Desert unparalleled in any language for its comprehensiveness. As such, it will be the essential starting point for future research on the Eastern Desert. Includes a CD of eleven audio files with music of the Ababda Nomads, and six short videos of Ababda culture.

Download or read book Desert Truffles written by Varda Kagan-Zur and published by Springer Science & Business Media. This book was released on 2013-10-30 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desert truffles are found in every known desert, irrespective of the habitat – cool or hot, loamy or acidic, sandy or heavy soil – the only common condition seems to be a limited supply of water. In contrast to ‘true’ truffles, desert truffles have evolved over time in different families, mainly within the order Pezizales. While in some arid areas, desert truffles have been traditionally used as food, in most regions interest has only recently been increasing, and truffles are now treasured for their nutritional value, as an income source and for research. This volume gives a comprehensive overview of the phylogeny, biology, mycorrhizal association, and distribution of desert truffles, their use, biochemical and medicinal properties, as well as their domestication and cultivation.
Download or read book The Awakening Desert written by Michael Evenari and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Michael Evenari's biography unfolds his exciting, manifold life: his love for botany, the confrontation with political events as a youngster and his thrilling experience of helping in the development of Israel. Evenari takes us on his exciting expeditions in the company of his beloved wife. He tells us of his meetings with many personalities and about his farm in the Negev. The discovery of long forgotten floodwater irrigated farm systems from the times of King Salomon and their reconstruction became a successful experiment which lead him to teach this approach of runoff agriculture in many parts of the world, initializing progress in the development of various arid areas. As a tribute to his successful scientific life, Evenari was awarded the Balzan Prize in 1988. In April 1989, Michael Evenari died at the age of 84.
Download or read book The End of Desertification written by Roy H. Behnke and published by Springer. This book was released on 2016-04-12 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. The concept of desertification, it can be argued, has ceased to be analytically useful and distorts our understanding of social-environmental systems and their resiliency, particularly in poor countries with variable rainfall and persistent poverty. For better policy and governance, we need to reconsider the scientific justification for international attempts to combat desertification. Our exploration of these issues begins in the Sahel of West Africa, where a series of severe droughts at the end of the 20th century led to the global institutionalization of the idea of desertification. It now seems incontrovertible that these droughts were not caused primarily by local land use mismanagement, effectively terminating a long-standing policy and scientific debate. There is now an opportunity to treat this episode as an object lesson in the relationship between science, the formation of public opinion and international policy-making. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept. Despite an increasingly sophisticated understanding of dryland environments and societies, the uses now being made of the desertification concept in parts of Asia exhibit many of the shortcomings of earlier work done in Africa. It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world.
