Facing The Sea Of Sand

Northern Africa is dominated by the Sahara Desert, stretching across the continent from the Atlantic Ocean to the Red Sea. This book is about the people who lived around the edges of the Desert and the different ways in which they responded to its challenges, establishing networks of communication across its expanse. But the Sahara has not always been a desert. From about 9000 BC the region began to enjoy a warm, humid period allowing vegetation to flourish and wild animals to move in. Humans soon followed practising pastoral economies but with the onset of harsher conditions once more around 3000 BC the desert reclaimed its own. Since then fluctuations in climate have continued to affect the lives of people living around the desert fringes. The communities occupying the North African Coast and in the Nile Valley have come under the influence of the states dominating the Near East and the Mediterranean but those living in in the Sahel to the south of the desert have developed their own distinctive cultures. The book tells the story of the growing links between the two worlds, showing that Africa played a crucial part in the development of the Old World before it was drawn into the story of the New World.

From Ty McCormick, winner of the Robert F. Kennedy Journalism Award, an epic and timeless story of a family in search of safety, security, and a place to call home. When Asad Hussein was growing up in the world’s largest refugee camp, nearly every aspect of life revolved around getting to America—a distant land where anything was possible. Thousands of displaced families like his were whisked away to the United States in the mid-2000s, leaving the dusty encampment in northeastern Kenya for new lives in suburban America. When Asad was nine, his older sister Maryan was resettled in Arizona, but Asad, his parents, and his other siblings were left behind. In the years they waited to join her, Asad found refuge in dog-eared novels donated by American charities, many of them written by immigrants who had come to the United States from poor and war-torn countries. Maryan nourished his dreams of someday writing such novels, but it would be another fourteen years before he set foot in America. The story of Asad, Maryan, and their family’s escape from Dadaab refugee camp is one of perseverance in the face of overwhelming adversity. It is also a story of happenstance, of long odds and impossibly good luck, and of uncommon generosity. In a world where too many young men are forced to make dangerous sea crossings in search of work, are recruited into extremist groups, and die at the hands of brutal security forces, Asad not only made it to the United States to join Maryan, but won a scholarship to study literature at Princeton—the first person born in Dadaab ever admitted to the prestigious university. Beyond the Sand and Sea is an extraordinary and inspiring book for anyone searching for pinpricks of light in the darkness. Meticulously reported over three years, it reveals the strength of a family of Somali refugees who never lost faith in America—and exposes the broken refugee resettlement system that kept that family trapped for more than two decades and has turned millions into permanent exiles.

This is a compilation of papers presented at the 6th International Conference on Asian and Pacific Coasts (APAC2011) held on December 14?16, 2011 in Hong Kong, China. It contains more than 200 articles addressing a wide spectrum of issues, ranging from conventional coastal engineering problems (such as wave hydrodynamics and sediment transport) to issues of contemporary interest (such as tsunami, coastal development, climate change and seawater level rise, shoreline protection, marine energy, nearshore ecology, oil spill, etc.). Authors present their experiences in tackling these problems, by means of theoretical modeling, numerical simulation, laboratory and field observations, with an aim to advance fundamental understanding of the controlling mechanisms, as well as to develop solutions for practical designs. This volume serves to promote technological progress and activities, technical knowledge transfer and cooperation on an international scale.

This Proceedings contains over 260 papers on cutting-edge research presented at the eighth international Symposium on Coastal Sediment Processes, held May 11 ? 15, 2015, in San Diego, California, USA. This technical specialty conference was devoted to promoting an interdisciplinary exchange of state-of-the-art knowledge among researchers in the fields of coastal engineering, geology, oceanography, and related disciplines, with the theme of Understanding and Working with Nature. Focusing on the physical aspects of the sediment processes in various coastal environments, this Proceedings provides findings from the latest research and newest engineering applications. Sessions covered a wide range of topics including barrier islands, beaches, climate and sea level, cohesive and noncohesive sediments, coastal bluffs, coastal marsh, dredged sediments, inlet and navigation channels, regional sediment management, river deltas, shore protection, tsunamis, and vegetation-sediment interaction. Several special sessions included: Relevant science for changing coastlines: A Tribute to Gary Griggs; North Atlantic Coast Comprehensive Study and post-super-storm Sandy work; long-term coastal evolution; barrier islands of Louisiana; sea-level rise and super storms in a warming world; predicting decadal coastal geomorphic evolution; and contrasting Pacific coastal behavior with El Ni¤o Southern Oscillation (ENSO), are also featured.

Sea, Sand and Sunshine are the elements of the pleasant memories of Alan Hunt's time spent in Libya, from the first glimpses of the Mediterranean Sea's clear blue waters to the Libyan Sahara Desert's bright white sands, and the endless reaches of blue sky as seen from ESSO's Convair aircraft on his first venture abroad. Join him as he explores, through sketches, photos and descriptive stories, the mystic Middle East and the lasting memories, actions, and incidents, both amusing and serious, with his fellow compatriots.

Jean-Pierre Cabestan, a China specialist based in Hong Kong, provides an overview of “Thucydides’ Trap,” as coined by political scientist Graham Allison to describe the inescapable conflict between Beijing and Washington. Is China’s growing power a threat to the United States? Could it lead to war between the two nations? Economically and militarily stronger, and more nationalist than ever, the People’s Republic of China is increasingly tempted to use force to assert its power, especially in its immediate region. First, the author considers the factors around the threat of war, specifically on the Chinese side, then presents the three most likely armed conflict scenarios: around Taiwan; in the South China Sea; or in the Senkaku Islands under Japanese control. Cabestan also analyses the tensions between China and India along their common borders, which were revived in 2020. But the most likely scenario, according to Cabestan, would be a rapid, piecemeal attack, aimed at tearing borders apart or defending vested interests – not to mention increased cyber warfare. It could also manifest itself as the emergence of a new type of cold war, punctuated by crises bordering on either a nuclear strike or the use of new weapons. U.S.-Chinese tensions and the many potential fronts on which they could elevate are a conflict-in-waiting which will weigh on the 21st century and dominate international life as China seeks to become entrenched as a dominant world power.
