In explaining how developments in the Kruger National Park have been integral to the wider political and socio-economic concerns of South Africa, this text opens an alternative perspective on its history. Nature protection has evolved in response to a variety of stimuli including white self-interest, Afrikaner nationalism, ineffectual legislation, elitism, capitalism and the exploitation of Africans.
This text is a synthesis of research in production and management since the inception of the discipline as an agricultural science in the 1930s. All the ecological regions are covered extensively, but the main emphasis is on the three biomes (grassland, savanna and karoo) which produce the bulk of the forage supporting the domestic livestock, conservation and the game farming industries. The book has an audience beyond the borders of South Africa in the grassland and savanna areas which stretch through southern and central Africa.;The text is aimed at students concerned with the management of natural ecosystems and also livestock producers and game ranchers who rely on the veld to feed their animals. The text throughout emphasizes the interpretation and application of research results to the practical situation.;All major aspects of veld production and management are covered in this book. It outlines the physiological and ecological principles on which management is based and which underpin the science. The book presents management options based on these underlying principles before dealing with recommended management procedures in each of the main ecological regions of the country.;The contributions to this book collectively represent a component of the expertise available on issues related to veld management in South Africa. They are veld and animal production researchers, conservation managers and planners working both at a practical level, closely in touch with livestock and game farmers, and at the more theoretical level as teachers at colleges and universities.
’I can’t recall us ever talking about anything other than eels and how to best catch them, down there by the stream. Actually, I can’t remember us speaking at all. Maybe because we never did.’ The European eel, Anguilla anguilla, is one of the strangest creatures nature ever created. Remarkably little is known about the eel, even today. What we do know is that it’s born as a tiny willow-leaf shaped larva in the Sargasso Sea, travels on the ocean currents toward the coasts of Europe – a journey of about four thousand miles that takes at least two years. Upon arrival, it transforms itself into a glass eel and then into a yellow eel before it wanders up into fresh water. It lives a solitary life, hiding from both light and science, for ten, twenty, fifty years, before migrating back to the sea in the autumn, morphing into a silver eel and swimming all the way back to the Sargasso Sea, where it breeds and dies. And yet . . . There is still so much we don’t know about eels. No human has ever seen eels reproduce; no one can give a complete account of the eel’s metamorphoses or say why they are born and die in the Sargasso Sea; no human has even seen a mature eel in the Sargasso Sea. Ever. And now the eel is disappearing, and we don’t know exactly why. What we do know is that eels and their mysterious lives captivate us. This is the basis for The Gospel of the Eels, Patrik Svensson’s quite unique natural science memoir; his ongoing fascination with this secretive fish, but also the equally perplexing and often murky relationship he shared with his father, whose only passion in life was fishing for this obscure creature. Through the exploration of eels in literature (Günter Grass and Graham Swift feature, amongst others) and the history of science (we learn about Aristotle’s and Sigmund Freud’s complicated relationships with eels) as well as modern marine biology (Rachel Carson and others) we get to know this peculiar animal. In this exploration, we also learn about the human condition, life and death, through natural science and nature writing at its very best.
As indigenous scientist and author of Braiding Sweetgrass Robin Wall
Kimmerer harvests serviceberries alongside the birds, she considers the
ethic of reciprocity that lies at the heart of the gift economy. How,
she asks, can we learn from indigenous wisdom and the plant world to
reimagine what we value most?
The world food situation is deteriorating. Grain stocks have dropped to a dangerously low level. The World Food Price Index has doubled in one decade. The ranks of the hungry are expanding; political unrest is spreading. On the demand side of the food equation, there will be 219,000 people at the dinner table tonight who were not there last night. And some 3 billion increasingly affluent people are moving up the food chain, consuming grain-intensive livestock and poultry products. At the same time, water shortages and heat waves are making it more difficult for farmers to keep pace with demand. As grain-exporting countries ban exports to keep their food prices down, importing countries are panicking. In response, they are buying large tracts of land in other countries to grow food for themselves. The land rush is on. Could food become the weak link for us as it was for so many earlier civilizations? Lester Brown, one of the leading environmentalists of our time, explains why world food supplies are tightening and tells what we need to do about it.
World Oceans: A Reference Handbook offers an in-depth discussion of the world's oceans. It discusses the marine life that is dependent on the sea as well as the problems threatening the health of the ocean and its wildlife. World Oceans: A Reference Handbook opens with an overview of the history of human knowledge and understanding of the oceans and cryosphere, along with related scientific, technological, social, political, and other factors. The second chapter presents and discusses about a dozen major problems facing the Earth's oceans today, along with possible solutions. The third chapter provides interested individuals with an opportunity to express their thoughts and ideas on today's ocean issues, and remaining chapters provide additional resources, such as a bibliography, a chronology, and a glossary, to assist the reader in her or his further study of the issue. Where most books for young adults learning about world oceans take a purely expository treatment, this book provides readers with additional information as well as resources, allowing them to learn more and inform further study of the subject. Provides readers with the basic background they need about the oceans and cryosphere in order to understand current problems Includes additional readings, a comprehensive chronology, a glossary, and other additional features to aid students' understanding of current issues and to guide them in designing and conducting their own research on more detailed aspects of the topic Offers ideas for additional research from a list of important individuals and organizations Rounds out the author's expertise in perspectives essays that show readers a diversity of viewpoints
An engaging, personalized look at the interplay between people and nature in the northeastern and midwestern United States, from prehistory to the present. The Northeast and Midwest regions of the United States provide a fascinating case study for the emergent field of environmental history. These regions, with their varied resources, were central to the early economic success of the nation. Consequently, the early industries in these regions altered and depleted the landscape as people changed their locations and occupations. Fishing and whaling on the northeastern coast have given way to tourism and sailing. The great stands of timber around the Great Lakes have been replaced by farms and dairies. The textile mills, powered by the falls of the Piedmont and once yielding wealth, now stand empty. That humans shape their environment and, in turn, must respond to the consequences is broadly obvious. Using the voices of historical figures, both notable and obscure, this book brings to life the interaction between humans and their environments and illustrates the consequences of those interactions. Part of ABC-CLIO's unique Nature and Human Societies series, this book enables readers to better understand humanity's effect on the environment. Maps and photographs show environmental regions, population movement, and changes to the environment by humans Separate listing of primary sources for all chapter topics, along with a bibliography and glossary
From an award-winning science journalist comes Nomad Century, an urgent investigation of environmental migration--the most underreported, seismic consequence of our climate crisis that will force us to change where--and how--we live. "The MOST IMPORTANT BOOK I imagine I'll ever read."--Mary Roach "An IMPORTANT and PROVOCATIVE start to a crucial conversation." --Bill McKibben "We are facing a species emergency. We can survive, but to do so will require a planned and deliberate migration of a kind humanity has never before undertaken. This is the biggest human crisis you've never heard of." Drought-hit regions bleeding those for whom a rural life has become untenable. Coastlines diminishing year on year. Wildfires and hurricanes leaving widening swaths of destruction. The culprit, most of us accept, is climate change, but not enough of us are confronting one of its biggest, and most present, consequences: a total reshaping of the earth's human geography. As Gaia Vince points out early in Nomad Century, global migration has doubled in the past decade, on track to see literal billions displaced in the coming decades. What exactly is happening, Vince asks? And how will this new great migration reshape us all? In this deeply-reported clarion call, Vince draws on a career of environmental reporting and over two years of travel to the front lines of climate migration across the globe, to tell us how the changes already in play will transform our food, our cities, our politics, and much more. Her findings are answers we all need, now more than ever.
Hundreds of millions of people still suffer from chronic hunger and
food insecurity despite sufficient levels of global food
production. The poor's inability to afford adequate diets remains
the biggest constraint to solving hunger, but the dynamics of
global food insecurity are complex and demand analysis that extends
beyond the traditional domains of economics and agriculture. How do
the policies used to promote food security in one country affect
nutrition, food access, natural resources, and national security in
other countries? How do the priorities and challenges of achieving
food security change over time as countries develop economically?
The Evolving Sphere of Food Security seeks to answer these two
important questions and others by exploring the interconnections of
food security to security of many kinds: energy, water, health,
climate, the environment, and national security.
Landowners and managers, municipalities, the logging and livestock industries, and conservation professionals all increasingly recognize that setting prescribed fires may reduce the devastating effects of wildfire, control invasive brush and weeds, improve livestock range and health, maintain wildlife habitat, control parasites, manage forest lands, remove hazardous fuel in the wildland-urban interface, and create residential buffer zones. In this practical and helpful manual, John R. Weir, who has conducted more than 720 burns in four states, offers a step-by-step guide to the systematic application of burning to meet specific land management needs and goals.
Over the last eight years I have spent much time looking into some really important questions: why do we have a climate and how has it changed? what role has the human race played in these changes? what will be the consequences if we continue burning fossils fuels? can we produce enough renewable, carbon neutral energy for the future, allowing for an increase in world population and for economic growth? The challenge - if we are to limit the long term global temperature rise to just 1 C above the current level, then we need to take urgent action. By 2050 the world must be producing seven times the amount of renewables we use today . This means that over the next 35 years we will have to develop these sources of energy 12 times faster than we've done in the last 35 years. We have to act now - this is our wake-up call. Getting governments to adopt policies with long term benefits is always difficult when they involve major short term investment but getting international agreement on limiting global warming is crucial. National targets must be agreed as well as an effective means of monitoring and enforcing them. Agreement must be based on the long term interests of the world not just on what is best "now, for me". Seven countries, China, USA, India, Russia, Japan, Canada and South Korea plus the EU account for three quarters of current greenhouse gas emissions. Negotiations must begin by getting these parties to agree on targets for themselves. They must then meet these targets and get everyone else to follow suit.
Here is the history of how exciting and innovative environmental education has been provided by the Countryside Education Trust for 40 years. People of all ages have visited the farm-based residential centre, a study centre in beautiful ancient woodland, or taken part in a range of countryside activities.
One of the great challenges of the 21st century is that of sustainability. This book aims to provide examples of sustainability in a wide variety of chemical contexts, in hope of laying the groundwork for cross-divisional work that might be possible in the future to address the important issue of sustainability. In doing so, the editors look at both the questions chemistry is asking right now related to sustainability as well as the questions chemistry SHOULD be asking about sustainability. The world is facing interrelated global challenges of energy, food, water, and human health. Solving these daunting challenges will require global systems thinking and proactive local action. No ONE company, academic institution, non-profit or government agency can accomplish this task alone, but it starts with education at all levels. This book addresses the need for better chemical education on the subject of sustainability.
A positive vision is emerging - a community-based, but globally linked and co-ordinated society, a global human family looking after each other and the Earth. eGaia describes starting points and next big steps where the starting points join and link up. It clarifies the vision, gives background, organising principles, and a light fictional picture of a sustainable world.
Introduction to the Concept of Greenhouse Tourism' is a book that comes following the call for global awareness on issues of climate change and need for sustainable development. The answer to the call is the need to respond to drastic adaptation behavioural in managerial paternalism, adopt mitigative measures and redress underpinning policies that champion the case for natural resource justice and fundamental reform in the educational system to generic view of our world as per the original metaphysical approach to social policy management. The teleological notion upon which the principle of intelligent design is construed remains the running spirit of theory, rallying henceforth the celebration of the Greenhouse effect.
