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.

A finalist for the PEN/E. O. Wilson Literary Science Writing Award The gripping story of the most important overlooked commodity in the world--sand--and the crucial role it plays in our lives. After water and air, sand is the natural resource that we consume more than any other--even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids to the Hubble telescope, from the world's tallest skyscraper to the sidewalk below it, from Chartres' stained-glass windows to your iPhone, sand shelters us, empowers us, engages us, and inspires us. It's the ingredient that makes possible our cities, our science, our lives--and our future. And, incredibly, we're running out of it. The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it--and sometimes, even kill for it. It's also a provocative examination of the serious human and environmental costs incurred by our dependence on sand, which has received little public attention. Not all sand is created equal: Some of the easiest sand to get to is the least useful. Award-winning journalist Vince Beiser delves deep into this world, taking readers on a journey across the globe, from the United States to remote corners of India, China, and Dubai to explain why sand is so crucial to modern life. Along the way, readers encounter world-changing innovators, island-building entrepreneurs, desert fighters, and murderous sand pirates. The result is an entertaining and eye-opening work, one that is both unexpected and involving, rippling with fascinating detail and filled with surprising characters.
