Dynamics and Diversity: Soil Fertility and Farming Livelihoods in Africa
by Ian ScoonesSoils are critical to agriculture and, in turn, to food supply and livelihoods. Sustainable management of soils is crucial for a large proportion of the population of Africa. Contrary to many claims, soil fertility is improved and managed successfully by small-scale farmers there. Careful studies from widely different areas reveal how closely bound up soil management is with complex social, cultural and ecological factors - requiring a far more subtly tuned approach to development policy and practice. This work is a study of how the context of livelihood systems has to inform development policy and practice.
The Dynamics of Agricultural Change: The Historical Experience (Routledge Library Editions: Agriculture #10)
by David GriggFirst published in 1982. Until the nineteenth-century the history of agriculture was the history of mankind but it has not perhaps received the wide attention that this importance justifies. In this study, the author reviews for the student of agricultural history successive attempts to describe and explain agricultural changes that are not specific to a limited area or a particular time. In a sense The Dynamics of Agricultural Change is a systematic historical geography of agriculture. Some of the models the author explores have been developed within agricultural history; some, drawn from other disciplines, can be applied fruitfully to it. What is the relationship between population growth and agricultural development? Between environmental changes and those in agriculture? What was the effect of the industrial revolution? And has there been an agricultural revolution? This book suggests to university students of economic history, historical geography and agriculture, a number of stimulating ways of interpreting and reinterpreting agricultural history.
Dynamics of Climate Change and Water Resources of Northwestern Himalaya
by Rajesh Joshi Kireet Kumar Lok Man S. PalniThis book is about the Himalayan ranges as a source of fresh water supply and a perennial store house of ice, snow and permafrost as well as a vast repository of rich biodiversity, in the light of climate change. Special attention is given to the dynamics of snow and glaciers in the northwestern Himalayas, assessment of climate change patterns, and the consequences of changes and flow regime in order to understand the behaviour of climate change in the northwestern Himalayas. The outcome of melting glaciers are pro-glacial lakes. Their increasing size and potential danger of outbursts requires systematic study, particularly where there is the risk of impact on life and property. Furthermore, the changing trend of the hydrological cycle on a regional or local scale is another area of research which calls for the attention of geoscientists. To date there is a scarcity of reliable data meaning that a concerted effort is still required by all parties.

Dynamics of the Pantanal Wetland in South America
by Ivan Bergier Mario Luis AssineThis book provides readers with in-depth insights into the changes in the Pantanal wetland from its formation to the actual and likely future states. It reveals that today's Pantanal is an evolutionary consequence of geological, ecological and, more recently, man-made events taking place at distinct space-time intervals. Topics include geotectonics and sun-earth interactions, which largely dictate the rate of drastic changes that eventually disrupt ecological stability and radically rebuild the regional landscape. Furthermore, the biota-climate system is discussed as a major driver reshaping the ecohydrology functioning of the landscape on an intermediate timescale. Also covered are major changes in the landscape ecohydrology and biodiversity due to recent land-use and climate changes induced by humankind in the Anthropocene. The ability to recognize how those temporal scales impact the Pantanal wetland provides the opportunity for wise management approaches and the sustainable development of the region.

E-Waste Management: Challenges and Opportunities in India
by Varsha Bhagat-GangulyThis book offers an extensive review of e-waste management in India, the world’s third‑largest producer of waste from electrical and electronic equipment. With a focus on the evolution of legalframeworks in India and the world, it presents impacts and outcomes; challenges and opportunities; and management strategies and practices to deal with e-waste. First of its kind, the book examines relevant concepts and issues from across 15 disciplines and six areas of policy making and will serve as a comprehensive knowledge base on electronic waste in India. It links key themes to the global context of Sustainable Development Goals and explores the convergence with technological, infrastructural, and social initiatives in e-waste management. A range of topics are discussed, such as resource efficiency policies; circular economy; toxicity; technicalities and complexities of e-waste management including role of the informal sector and need for recognising social and human costs in policy making. The book deals with the role of statistics; legal trends and reforms; linkages with green Agenda 2030 and UN initiatives; implementation of Extended Producer Responsibility (EPR); environmental factors; business prospects; consequences on human health; Life Cycle Impact Assessment; the ‘six Rs’ (Responsible use, Repair, Refurbish, Recycle, Recover and Reuse); recycling practices and problems, material flow and informal sector in trade value chain; fostering partnership between formal-informal sectors; safe disposal; alternatives to landfilling; role of jurisprudence and regulatory bodies; and education and awareness. It also includes a survey of pan-India initiatives and trajectories of law-driven initiatives for effective e-waste management along with responses from industries and producers. Timely and essential, this volume will be useful to scholars and researchers of environment studies, digital waste management, waste management, development studies, public policy, political ecology, sustainable development, technology and manufacturing, design and instrumentation, environmental and international law, taxation, commerce, electronic industry, economics, business management, metallurgy, and engineering, labour studies, as well as to policymakers, nongovernmental organisations, and interested general readers.
Each One a Furnace: Poems
by Tolu OloruntobaFrom the author of The Junta of Happenstance, here is a brilliant new collection of poems—a burning chronicle of passage and stillness and restlessness.Each One a Furnace explores (im)migration, diasporas, transience, and instability by following the behaviour, and abundant variety, of finches. The often-migratory birds in these poems typify the unrest, and inability to rest, that animate the lives of billions in the modern world. Out of the register of ornithology, themes of difficulty, adversity, and migrancy, urban ennui, and the psychic struggles of diasporic peoples take shape as those unable to be at rest in the world take to improbable flight. Trailing the global mobility of birds, in urban and non-urban settings, in historical and contemporary contexts, and through the metaphysical and concrete, Each One a Furnace is a chronicle of struggle within, and between, cultures.
Eager: The Surprising, Secret Life of Beavers and Why They Matter
by Ben GoldfarbIn Eager, environmental journalist Ben Goldfarb reveals that our modern idea of what a healthy landscape looks like and how it functions is wrong, distorted by the fur trade that once trapped out millions of beavers from North America’s lakes and rivers. The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”—including scientists, ranchers, and passionate citizens—recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world’s most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it’s about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

Eagle Rock Reservation (Images of America)
by Joseph FaganFounded in 1895, the Essex County Park Commission was the first county park system in the nation. That year, the commission began its management of Eagle Rock. The reservation was designed by renowned architect Frederick Law Olmsted Sr., who also designed Central Park in New York City and the Capitol Grounds in Washington, D.C. Evident characteristics of the architect within the park are the winding roads, natural blended waterways, open fields, and overlooks, all of which combine to attract thousands of visitors each year. Eagle Rock Reservation explores many interesting and little-known facts about the park. Readers are introduced to Llewellyn Haskell, the founder of nearby Llewellyn Park, who first purchased land at Eagle Rock. Seen is the trolley that once served Eagle Rock as it emerged as a popular resort area. Included are the park's view of the New York City skyline and the Hundred Steps to Eagle Rock, the same steps that were ascended by visitors nearly one hundred years ago. Also seen is a never-before-published lab note written by Thomas Edison, documenting World War I experiments he conducted for the U.S. Navy at Eagle Rock.
The eagle watchers: observing and conserving raptors around the world
by Ruth E. Tingay Todd E. Katzner Keith L. Bildstein Jemima Parry-JonesEagles have fascinated humans for millennia. For some, the glimpse of a distant eagle instantly becomes a treasured lifelong memory. Others may never encounter a wild eagle in their lifetime. This book was written by people who have dedicated years to the study of eagles, to provide an insider's view for all readers, but especially those who have never been up close and personal with these magnificent yet often misunderstood creatures.In their stories, twenty-nine leading eagle researchers share their remarkable field experiences, providing personal narratives that don't feature in their scientific publications. They tell of their fear at being stalked by grizzly bears, their surprise at being followed by the secret police, their embarrassment when accidentally firing mortar rockets over a school gymnasium, and their sense of awe at tracking eagles via satellite. The reader experiences the cultural shock of being guest of honor at a circumcision ceremony, the absurdity of sharing an aquatic car with the Khmer Rouge, and the sense of foreboding at being press-ganged into a frenzied tribal death march through the jungle. The Eagle Watchers covers twenty-four species on six continents, from well known (bald eagle; golden eagle), to obscure (black-and-chestnut eagle; New Guinea harpy eagle), and from common (African fish eagle) to critically endangered (Philippine eagle; Madagascar fish eagle). The diverse experiences vividly described in this book reveal the passion, dedication, and sense of adventure shared by those who study these majestic birds and strive for their conservation. Featuring stunning color photographs of the eagles, information on raptor conservation, a global list of all eagle species with ranges and conservation status, and a color map of the sites visited in the book, The Eagle Watchers will appeal to birders, conservationists, and adventure travelers alike. To further support the conservation programs described in this book, all royalties are being donated to two leading nonprofit organizations for raptor conservation training and fieldwork: Hawk Mountain Sanctuary Intern Program and the National Birds of Prey Trust.
Early Ascents on Pikes Peak (American Chronicles Ser.)
by Woody SmithAn intriguing, firsthand look at what it was like to ascend the storied Colorado mountain and experience its allure in the early days of the Old West. Magnificent Pikes Peak rises dramatically from the Colorado prairie to a height of 14,114 feet above sea level. Visible for one hundred miles around, the granite giant&’s magnetic appeal compelled rugged mountaineers more than a century ago to risk loose saddles, electrical storms and even murder on treacherous expeditions to the summit. First known as Long Mountain by the Indigenous peoples who sojourned at its hot springs, Pikes Peak was a full-fledged tourist destination by the 1870s. Eager men and women ventured up and down by foot, horse, burro, stagecoach, rail and bicycle. Colorado Mountain Club historian Woody Smith captures the news of the era to recount the thrill of pioneer days on America&’s most famous mountain.

Early Days in the Range of Light: Encounters with Legendary Mountaineers
by Daniel ArnoldIt's 1873. Gore-Tex shells and aluminum climbing gear are a century away, but the high mountains still demand your attention. Imagine the stone in your hands and thousands of feet of open air below you, with only a wool jacket to weather a storm and no rope to catch a fall. Daniel Arnold did more than imagine - he spent three years retracing the steps of his climbing forefathers, and in Early Days in the Range of Light, he tells their riveting stories. From 1864 to 1931, the Sierra Nevada witnessed some of the most audacious climbing of all time. In the spirit of his predecessors, Arnold carried only rudimentary equipment - no ropes, no harness, no specialized climbing shoes. Sometimes he left his backpack and sleeping bag behind as well, and, like John Muir, traveled for days with only a few pounds of food rolled into a sack slung over his shoulder.In an artful blend of history, biography, nature, and adventure writing, Arnold brings to life the journeys and the terrain traveled. In the process he uncovers the motivations that drove an extraordinary group of individuals to risk so much for airy summits and close contact with bare stone and snow.
Early Events in Monocot Evolution
by Paul Wilkin Simon J. MayoTracing the evolution of one of the most ancient major branches of flowering plants, this is a wide-ranging survey of state-of-the-art research on the early clades of the monocot phylogenetic tree. It explores a series of broad but linked themes, providing for the first time a detailed and coherent view of the taxa of the early monocot lineages, how they diversified and their importance in monocots as a whole. Featuring contributions from leaders in the field, the chapters trace the evolution of the monocots from largely aquatic ancestors. Topics covered include the rapidly advancing field of monocot fossils, aquatic adaptations in pollen and anther structure and pollination strategies and floral developmental morphology. The book also presents a new plastid sequence analysis of early monocots and a review of monocot phylogeny as a whole, placing in an evolutionary context a plant group of major ecological, economic and horticultural importance.
Early Exchange between Africa and the Wider Indian Ocean World
by Gwyn CampbellThis volume comprises a selection of essays by scholars from a variety of disciplines that discuss the exchange relationship between Africa and the wider Indian Ocean world (IOW), a macro-region running from East Africa to China, from early times to about 1300 CE. The rationale for regarding this macro-region as a "world" is the central significance of the monsoon system which facilitated the early emergence of long-distance trans-IOW maritime exchange of commodities, peoples, plants, animals, technologies and ideas.

Early Warming: Crisis and Response in the Climate-Changed North
by Nancy LordIn Shishmaref, Alaska, new seawalls are constructed while residents navigate the many practical and bureaucratic obstacles to moving their entire island village to higher ground. Farther south, inland hunters and fishermen set out to grow more of their own food-and to support the reintroduction of wood bison, an ancient species well suited to expected habitat changes. First Nations people in Canada team with conservationists to protect land for both local use and environmental resilience.In Early Warming, Nancy Lord takes a cutting-edge look at how communities in the North-where global warming is amplified and climate-change effects are most immediate-are responding with desperation and creativity. This beautifully written and measured narrative takes us deep into regions where the indigenous people who face life-threatening change also demonstrate impressive conservation ethics and adaptive capacities. Underpinned by a long acquaintance with the North and backed with scientific and political sophistication, Lord's vivid account brings the challenges ahead for us all into ice-water clarity.
Earth: Feeling the Heat
by Brenda Z. GuibersonIN EVERY CORNER of the world, humans zoom zoom from here to there, push buttons, turn keys, and flip switches. With clever inventions, people fly like birds and keep warm like polar bears. But to do these things, humans burn oil, gas, and coal, all of which release particles into the air. These particles hover over the earth like a thick blanket that traps sunshine and makes everything extra warm. This is called global warming. People and all the animals are feeling the heat. You can help by using less energy. Even the little things you do can make a big difference!

Earth: The Race to Reinvent Energy and Stop Global Warming
by Fred Krupp Miriam HornHOW TO HARNESS THE GREAT FORCES OF CAPITALISM TO SAVE THE WORLD FROM CATASTROPHE. The forecasts are grim and time is running out, but that's not the end of the story. In this book, Fred Krupp, longtime president of Environmental Defense Fund, brings a stirring and hopeful call to arms: We can solve global warming. And in doing so, we will build the new industries, jobs, and fortunes of the twenty-first century. In these pages the reader will encounter the bold innovators and investors who are reinventing energy and the ways we use it. Among them: a frontier impresario who keeps his ice hotel frozen all summer long with the energy of hot springs; a utility engineer who feeds smokestack gases from coal-fired plants to voracious algae, then turns them into fuel; and a tribe of Native Americans, for two thousand years fishermen in the roughest Pacific waters, who are now harvesting the fierce power of the waves themselves. These entrepreneurs are poised to remake the world's biggest business and save the planet-if America's political leaders give them a fair chance to compete.
