Download or read book Mathematical Methods for Economic Theory 2 written by James C. Moore and published by Springer Science & Business Media. This book was released on 1999-10-19 with total page 1012 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work functions both as a textbook for graduates and as a reference for economic scholars. Assuming only the minimal mathematics background required of every second-year graduate in economics, the two volumes provide a self-contained and careful development of mathematics through locally convex topological vector spaces, and fixed-point, separation, and selection theorems in such spaces. This second volume introduces general topology, the theory of correspondences on and into topological spaces, Banach spaces, topological vector spaces, and maximum, fixed-point, and selection theorems for such spaces

Download or read book A Distant Light written by Henry W. Kendall and published by Springer. This book was released on 2013-12-23 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of essays by a Nobel Prize Laureate on a wide range of problems facing the world, and the role of scientists in solving them. Kendall was one of a group of physicists who founded the Union of Concerned Scientists (UCS) and is currently chairman of its board of directors. UCS is today a voice of authority in US government science policy, particularly with regard to environment issues. Together, these essays represent both the successes and failures of science to impact public policy, and offer practical guidelines for involvement in science policy. They are roughly chronological, organised by subject with introductions, beginning with the controversies on nuclear power safety and Three Mile Island, then followed by sections on national security issues, global environmental and resource problems, and radioactive cleanup. Kendall's Nobel Prize lecture is also included (and is the only really technical material in the book), while the photos are from a 1992 exhibition of his work.

Download or read book Agricultural Ecology and Environment written by B.R. Stinner and published by Elsevier. This book was released on 2012-12-02 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability.The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.

Book excerpt: Peter Lindert evaluates environmental concerns about soil degradation in two very large countries—China and Indonesia—where anecdotal evidence has suggested serious problems. In this book Peter Lindert evaluates environmental concerns about soil degradation in two very large countries—China and Indonesia—where anecdotal evidence has suggested serious problems. Lindert does what no scholar before him has done: using new archival data sets, he measures changes in soil productivity over long enough periods of time to reveal the influence of human activity. China and Indonesia are good test cases because of their geography and history. China has been at the center of global concerns about desertification and water erosion, which it may have accelerated with intense agriculture. Most of Indonesia's lands were created by volcanoes and erosion, and its rapid deforestation and shifting slash-burn agriculture have been singled out for international censure. Lindert's investigation suggests that human mismanagement is not on average worsening the soil quality in China and Indonesia. Human cultivation lowers soil nitrogen and organic matter, but has offsetting positive effects. Economic development and rising incomes may even lead to better soil. Beyond the importance of Lindert's immediate findings, this book opens a new area of study—quantitative soil history—and raises the standard for debating soil trends.
Download or read book Ecosystems of Disturbed Ground written by L.R. Walker and published by Elsevier. This book was released on 1999-12-17 with total page 881 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population inexorably grows, its cumulative impact on the Earth's resources is hard to ignore. The ability of the Earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. This book is the first to take a global approach to the description of both natural and anthropogenic disturbance regimes that physically impact the ground. Natural disturbances such as erosion, volcanoes, wind, herbivory, flooding and drought plus anthropogenic disturbances such as foresty, grazing, mining, urbanization and military actions are considered. Both disturbance impacts and the biotic recovery are addressed as well as the interactions of different types of disturbance. Other chapters cover processes that are important to the understanding of disturbance of all types including soil processes, nutrient cycles, primary productivity, succession, animal behaviour and competition. Humans react to disturbances by avoiding, exacerbating, or restoring them or by passing environmental legislation. All of these issues are covered in this book.Managers need better predictive models and robust data-collections that help determine both site-specfic and generalized responses to disturbance. Multiple disturbances have a complex effect on both physical and biotic processes as they interact. This book provides a wealth of detail about the process of disturbance and recovery as well as a synthesis of the current state of knowledge about disturbance theory, with extensive documentation.
Download or read book Agricultural Science Policy written by Julian M. Alston and published by Intl Food Policy Res Inst. This book was released on 2001-01-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural research and development have profoundly increased the quantity and quality of food production in the twentieth century. As populations increase, however, and land and water resources become more scarce, we must improve productivity and efficiency to provide adequate food supplies. Issues such as the environment, genetic diversity, food safety, poverty, human health, animal rights, public versus private responsibilities, and the question of intellectual property rights further complicate this task. Agricultural Science Policy: Changing Global Agendas consists of twelve chapters that describe important issues in agricultural science policy, the relevant facts, current economic thinking, and new results. Topics Include: Changing Global Contexts and Agendas for Agricultural R & D; Productivity Measures and Measurement; Research, Productivity, and Natural Resources; Research for Genetic Improvement; and a Conclusion, which suggests directions for the future. The chapters in this volume will provide researchers and policy makers with a timely review of progress on the existing agenda as well as laying the foundation for a new agenda and new directions for global agricultural science policy in the 21st century.

Download or read book Climate Change and World Food Security written by Thomas E. Downing and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last half decade since sustainable development became a serious objective, what have we achieved? Are livelihoods more secure? Are nations wealthier and more resilient? Is environmental quality being restored or maintained? These are essential questions of development. Their answers are many, varied between communities and regions, even between individuals. Two years ago, in the aftermath of the Earth Summit and ratification of the Framework Convention on Climate Change, but before the first Conference of Parties, I participated in a panel at the inaugural Oxford Environment Conference on Climate Change and World Food Security. The panel vigorously reviewed issues of resilient development and food security. This book is a product of the Oxford Environment Conference. It takes the essential questions of sustainability as a starting point to focus on present food security and its future prospects in the face of climate change. Why is this book important? First, I believe our goals to end hunger are under threat. We know what to do in many respects, but fail to generate the finances and political will to change the structures that thrive on poverty. Second, I believe concern about the environment has become dangerously separated from the fundamental issues of human deprivation. Third, I believe climate change is a serious threat and I am dismayed at the way nations dither over how to control greenhouse gas emissions and mechanisms to meet the challenge of adverse climate impacts.
