Available in PDF, EPUB and Kindle. Book excerpt: The little-known history of how the Sahara was transformed from a green and fertile land into the largest hot desert in the world The Sahara is the largest hot desert in the world, equal in size to China or the United States. Yet, this arid expanse was once a verdant, pleasant land, fed by rivers and lakes. The Sahara sustained abundant plant and animal life, such as Nile perch, turtles, crocodiles, and hippos, and attracted prehistoric hunters and herders. What transformed this land of lakes into a sea of sands? When the Sahara Was Green describes the remarkable history of Earth’s greatest desert—including why its climate changed, the impact this had on human populations, and how scientists uncovered the evidence for these extraordinary events. From the Sahara’s origins as savanna woodland and grassland to its current arid incarnation, Martin Williams takes us on a vivid journey through time. He describes how the desert’s ancient rocks were first fashioned, how dinosaurs roamed freely across the land, and how it was later covered in tall trees. Along the way, Williams addresses many questions: Why was the Sahara previously much wetter, and will it be so again? Did humans contribute to its desertification? What was the impact of extreme climatic episodes—such as prolonged droughts—upon the Sahara’s geology, ecology, and inhabitants? Williams also shows how plants, animals, and humans have adapted to the Sahara and what lessons we might learn for living in harmony with the harshest, driest conditions in an ever-changing global environment. A valuable look at how an iconic region has changed over millions of years, When the Sahara Was Green reveals the desert’s surprising past to reflect on its present, as well as its possible future.
Download or read book Mobile Technologies in the Ancient Sahara and Beyond written by Chloë N. Duckworth and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume is the fourth and final volume resulting from a focused programme of research and intensive group discussion of a wide range of topics related to the archaeological (and to a lesser extent, historical and anthropological/ethnographic) analysis of ancient societies in and around the Sahara, from the first millennium BC to the mid-second millennium AD. While the focus of the present volume is technology, there will inevitably be discussion of cross-overs and contrasts with the main conclusions from earlier volumes in the series. As explained in the Preface above, the Trans-SAHARA project evolved out of a long-term programme of fieldwork on an ancient people of the Libyan Sahara. Just as they occupied a significant nodal location in the Sahara, the Garamantes are at the centre of this volume, but the scope of debate here extends way beyond the history of a single group. Connections and barriers within the Trans-Saharan region (and the interrelationship between these two aspects) form one focus. In this introduction we present an overview of crucial themes and considerations which cross-cut all or many of the contributions."--
Download or read book The Secret Knowledge of Water written by Craig Childs and published by Back Bay Books. This book was released on 2008-12-14 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Naturalist Craig Childs's "utterly memorable and fantastic" study of the desert's dangerous beauty is based on years of adventures in the deserts of the American West (Washington Post). Like the highest mountain peaks, deserts are environments that can be inhospitable even to the most seasoned explorers. Craig Childs, who has spent years in the deserts of the American West as an adventurer, a river guide, and a field instructor in natural history, has developed a keen appreciation for these forbidding landscapes: their beauty, their wonder, and especially their paradoxes. His extraordinary treks through arid lands in search of water are an astonishing revelation of the natural world at its most extreme. "Utterly memorable and fantastic...Certainly no reader will ever see the desert in the same way again." —Suzannah Lessard, Washington Post
Download or read book Desert Kingdom written by Toby Craig Jones and published by Harvard University Press. This book was released on 2011-03-15 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil and water, and the science and technology used to harness them, have long been at the heart of political authority in Saudi Arabia. Oil’s abundance, and the fantastic wealth it generated, has been a keystone in the political primacy of the kingdom’s ruling family. The other bedrock element was water, whose importance was measured by its dearth. Over much of the twentieth century, it was through efforts to control and manage oil and water that the modern state of Saudi Arabia emerged. The central government’s power over water, space, and people expanded steadily over time, enabled by increasing oil revenues. The operations of the Arabian American Oil Company proved critical to expansion and to achieving power over the environment. Political authority in Saudi Arabia took shape through global networks of oil, science, and expertise. And, where oil and water were central to the forging of Saudi authoritarianism, they were also instrumental in shaping politics on the ground. Nowhere was the impact more profound than in the oil-rich Eastern Province, where the politics of oil and water led to a yearning for national belonging and to calls for revolution. Saudi Arabia is traditionally viewed through the lenses of Islam, tribe, and the economics of oil. Desert Kingdom now provides an alternative history of environmental power and the making of the modern Saudi state. It demonstrates how vital the exploitation of nature and the roles of science and global experts were to the consolidation of political authority in the desert.

Book excerpt: "Poetic language, attractive illustrations and a positive message about Islam, without any didacticism: a wonderful combination," declares Kirkus Reviews in a starred review. Lalla lives in the Muslim country of Mauritania, and more than anything, she wants to wear a malafa, the colorful cloth Mauritanian women, like her mama and big sister, wear to cover their heads and clothes in public. But it is not until Lalla realizes that a malafa is not just worn to show a woman's beauty and mystery or to honor tradition—a malafa for faith—that Lalla's mother agrees to slip a long cloth as blue as the ink in the Koran over Lalla's head, under her arm, and round and round her body. Then together, they pray. An author's note and glossary are included in the back of the book.

Download or read book North to Paradise written by Ousman Umar and published by AmazonCrossing. This book was released on 2022-03 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inspiring true story of one man's treacherous boyhood journey from a rural village in Ghana to the streets of Barcelona--and the path that led him home. Ousman Umar is a shaman's son born in a small village in Ghana. Though his mother died giving birth, he spent a contented childhood working the fields, setting traps in the jungle, and living off the land. Still, as strange and wondrous flying machines crisscrossed the skies overhead, Ousman dreamed of a different life. And so, when he was only twelve years old, he left his village and began what would be a five-year journey to Europe. Every step of the way, as he traveled across the Sahara Desert, through the daunting metropolises of Accra, Tripoli, Benghazi, and Casablanca, and over the Mediterranean Sea aboard a packed migrant dinghy, Ousman was handed off like merchandise by a loose network of smugglers and in the constant, foreboding company of "sinkers" other migrants who found themselves penniless and alone on their way north, unable to continue onward or return home. But on a path rife with violence, exploitation, and racism, Ousman also encountered friendship, generosity, and hope. North to Paradise is a visceral true story about the stark realities of life along the most dangerous migrant route across Africa; it is also a portrait of extraordinary resilience in the face of unimaginable challenges, the beauty of kindness in strangers, and the power of giving back.

Download or read book The Sahara written by Eamonn Gearon and published by Oxford University Press, USA. This book was released on 2011 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sahara is the quintessence of isolation, epitomizing both remoteness and severity of environment unlike any other place on the face of the earth. Replete with myths and fictions, it is a wild land, dotted with oases and camel trains trudging through sand dunes that roll like the waves on a sea, as far as the distant horizon. But this is just part of the picture. The largest desert in the world, the Sahara ranges from the river Nile running through Egypt and Sudan in the east, to the Atlantic coast from Morocco to Mauritania in the west; stretching from the Atlas Mountains and the shores of the Mediterranean in the north, to the fluid Sahelian fringe that delineates the desert in the south. Invaders and traders have come and gone for millennia, but the Sahara is also the place that some people call home. While larger than the United States, this vast area contains only three million people: Africans and Arabs, Berber and Bedu, Tuareg and Tebu. Eamonn Gearon explores the history, culture, and terrain of a place whose name is familiar to all, but known to few. Conquered and Cursed: from the 50,000-strong army of Cambyses, swallowed in a sandstorm in the sixth century BC, to the US Marines' first foreign engagement, in 1805; Hannibal and his elephants, Caesar against Anthony and Cleopatra, Alexander the Great, the armies of Islam, Napoleon, and Rommel versus Monty. Myths and Mysteries: from whales in the White Desert to the arrival of camels in the Great Sand Sea; chariots of the gods and colonialists' motor-cars; from the Land of the Dead to Timbuktu; salt and gold mines, fields of oil and gas and a man-made river. Artists, Writers, and Filmmakers: from the ancient rock art of the Tassili frescoes to the modernism of Matisse and Klee; from Ibn Battuta to Paul Bowles; from Beau Geste's French Foreign Legion to Star Wars.

Download or read book Revive Eden written by Hong-Quan Zhang and published by Bookbaby. This book was released on 2021-06-03 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantis is not hiding at the bottom of the Atlantic Ocean but in plain view on top of the Sahara Desert. The prosperity of the Atlas Empire and the inundation of Atlantis corresponded to a lush Green Sahara started around 12,000 years ago. About 5700 years ago, the Green Sahara suddenly began to wither from the Atlas Basin, the heartland of the Atlas Empire. This is the rain shadow area of the Atlas Mountain range in today's Northeast Algeria and South Tunisia. When the water cycle stability in this standalone catchment was broken, the Chotts Megalakes (the Atlantic Sea) dried rapidly and the strong rain shadow effect of the Atlas Mountain became fully active. Deserts formed immediately in this area and gradually expanded east and south, like a spreading wildfire powered by the prevailing winds. This led to desertification and aridification in North Africa, West Asia, and the Mediterranean synchronously until this day. This timeline spans most of human history as we know it, including the thriving and dispersion of Atlas Empire, the rise and fall of Egypt, the prosperity and desolation of Mesopotamia, and the civilization shifts first from west to east and then from east to west across the Mediterranean and the Atlantic. The Atlantic Sea had a surface area over 26,000 sq km, which generated a great amount of water vapor, sufficient to eliminate the strong rain shadow effect of the Atlas Mountain, so that the Green Sahara was stabilized for about six thousand years. The Earth's precession (wobbling) has been blamed as the main control for the flipping between desert and green in the Sahara. This view has misled the academic society away from seeking the true primary cause for so long. The water cycle stability of the Sahara is governed by the non-linear relationship between precipitation and evaporation, which depends on surface conditions and atmospheric circulation. The Earth's precession only moved the water cycle closer to its unstable point so that a perturbation could trigger the transition from wet to dry state. This book explains the start and step-by-step spread of the Sahara Desert and its impact on West Asia and the Mediterranean regions. Archaeological records and paleoclimate data corroborate this new insight of the Sahara expansion process and the consequential desertification in these areas. The desertification process in Northwest China is an independent validation for the same control mechanism. Based on the new understanding, approaches are suggested to revive the Northwest China ecosystem, to turn the Sahara back to green and to ameliorate Australia to a water abundant country.
