Book excerpt: The following article is an attempt to discover the mechanism that shapes the fish catches in the oceans and seas. Previous ocean biology studies have found a relationship between fish catches and regional climate change. The author speculates that the same cosmic factors that shape the Earth's climate affect the biological production of the ocean. It is, therefore, necessary to describe the Earth's climate mechanism and we will find the reasons for the variability of fish catches then. Changes in the magnetic activity of the Sun are caused by changes in the gravitational forces of the Solar System, which at the same time interact with the northern hemisphere, which is heavier than the southern hemisphere, causing the Earth's coating to rotate around the Earth's core. The rotation of the earth's coating consisting of crust and mantle is reflected by apparent changes in the location of North Magnetic Field NMP found in paleomagnetic studies. The rotation of the Earth's coating causes changes in the moment of inertia of the Earth's geoid, and thus changes in length of earth’s day LOD, and changes in the centrifugal force affecting the inertial ocean waters and the Earth's crust. Changes in the centrifugal force acting in the surface of the globe caused changes in the Global Mean Sea Level GMSL (the largest changes occur at the equator due to the highest linear speed of Earth's rotation) and changes in upwelling - i.e. movement of vertical and horizontal ocean water caused by centrifugal force. Changes in ocean upwelling cause cooling of ocean water and changes in ocean biological productivity that are correlated with changes in Length Of Earth's Day LOD, changes in Earth's climate (El Nino Southern Oscillation ENSO, Pacific Decadal Oscillation PDO, North Atlantic Oscillation NAO, East Asian Monsoon EAM, Sea Level Pressure SLP), cloud cover over oceans, Earth's flattening coefficient J2 and delta C20, and carbon dioxide emissions from the ocean into the atmosphere. Changes in the centrifugal force acting on the rotating Earth cause displacement of tectonic plates of the earth's crust and changes in the number of 2 earthquakes, as well as the formation and development of subduction zones in which hydrocarbons and other minerals are formed. The relationship between changes in solar activity measured by the number of spots on the sun and changes in LOD confirms the correlation of the physicochemical phenomena described above on Earth with changes in gravity in the solar system. Because LOD changes are correlated with changes in ocean biological productivity and the Earth Orientation Center IERS service provides a semi-annual forecast of LOD changes, it is possible to predict periods of more abundant catches of marine organisms. Seasons of heavy fishing in the ocean occur during significant changes in the Earth's rotational speed accompanied by the cooling of the Sea Surface Temperature SST. Increasing catches will probably be possible because the long-term period of large displacements of the Earth's coating is approaching, which will be accompanied by large changes in the Earth's rotation speed and global cooling of the climate due to the cooling of ocean water. Confirmation of these future geophysical phenomena is important for securing sufficient food supply for human society.

This book was released on 2001 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: * Comprehensive assessment from the leading German environmental scientists of the state of the world's living resources or biosphere * Covers all aspects of the subject: biodiversity and genetic diversity, landscape and ecosystems, its role in the Earth's system and human impacts on it * Reviews global policies and research strategies on the biosphere and advocates urgent policy actions * A major, authoritative contribution to environmental science and policy Biodiversity- the planet's natural capital- is undergoing a dramatic collapse: its " Sixth Extinction". The losses, which are do to human activities and overexploitation of the biosphere, are irreversible. They are undermining the basis of future well-being and prosperity, including genetic resources and food production, climate stability, and coastal and soil protection. The scientists of the German Advisory Council on Global Change have produced an authoritative and alarming analysis of the state of the biosphere. They show that the time remaining for remedial action is fast disappearing and they set out a range of initiatives to be undertaken at different levels. Among their main urgent recommendations are: * protecting 10-20% of the global land area * an Intergovernmental Panel on Biodiversity to provide scientific advice * conservation of the diversity of cultivated as well as wild plant species * greater multilateral cooperation and implementation of the Convention on Biological Diversity The volume makes a highly significant contribution to the scientific and policy debates on these critical issues. It will be essential reading for those engaged with them.

Available in PDF, EPUB and Kindle. Book excerpt: Economic growth, reflected in increases in national output per capita, makes possible an improved material standard of living and the alleviation of poverty. Sustainable development, popularly and concisely defined as ‘meeting the needs of the present generations without compromising the ability of future generations to meet their needs,' directly addresses the utilization of natural resources, the state of the environment, and intergenerational equity. Now in its second edition, Economic Growth and Sustainable Development features expanded discussion of income distribution, social capital and the insights of behavioural economics for climate change mitigation. Boxed case studies have been added which explore the impact of economic growth on people and countries in both the developed and developing world. This text addresses the following fundamental questions: What causes economic growth? Why do some countries grow faster than others? What accounts for the extraordinary growth in the world’s population over the past two centuries? What are the current trends in population and will these trends continue? How do we measure sustainable development and is sustainable development compatible with economic growth? Why is climate change the greatest market failure of all time? What can be done to mitigate climate change and global warming? With a blend of formal models, empirical evidence, history and policy, this text provides a coherent and comprehensive treatment of economic growth and sustainable development. It is suitable for those who study development economics, sustainable development and ecological economics.

Download or read book Ecosystems Oceans written by Trevor Day and published by Routledge. This book was released on 2014-07-10 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oceans are teeming with life of all kinds. Changing sea levels, plate tectonics, chemical cycling, sedimentation, and the atmosphere greatly impact these habitats. The ocean's currents and sea level are tied closely to weather patterns and in turn to such issues as global warming and El Nino. Oceans provides a complete overview of the ecosystem that exists in these bodies of water. From the coastal wetlands to the deep ocean waters, the geography, geology, chemistry, and physics of oceans are thoroughly examined in this volume. Today, the impact that human use of ocean resources has on these habitats, including habitat loss and overharvesting, is in constant debate. Oceans looks at these possible threats and concludes with a balanced look at the ways to manage the oceans, as well as the future of this ecosystem.

Download or read book From Summits to Solutions written by Hiroshi Kato and published by Brookings Institution Press. This book was released on 2018-07-24 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: A positive agenda for achieving the Sustainable Development Goals by 2030 All 193 member nations of the United Nations agreed in September 2015 to adopt a set of seventeen "Sustainable Development Goals," to be achieved by 2030. Each of the goals—in such areas as education and health care —is laudable in and of itself, and governments and organizations are working hard on them. But so far there is no overall, positive agenda of what new things need to be done to ensure the goals are achieved across all nations. In a search of fresh approaches to the longstanding problems targeted by the Sustainable Development Goals, the Japan International Cooperation Agency and the Global Economy and Development program at Brookings mounted a collaborative research effort to advance implementation of Agenda 2030. This edited volume is the product of that effort. The book approaches the UN's goals through three broad lenses. The first considers new approaches to capturing value. Examples include Nigeria's first green bonds, practical methods to expand women's economic opportunities, benchmarking to reflect business contributions to achieving the goals, new incentives for investment in infrastructure, and educational systems that promote cross-sector problem solving. The second lens entails new approaches to targeting places, including oceans, rural areas, fast-growing developing cities, and the interlocking challenge of data systems, including geospatial information generated by satellites. The third lens focuses on updating governance, broadly defined. Issues include how civil society can align with the SDG challenge; how an advanced economy like Canada can approach the goals at home and abroad; what needs to be done to foster new approaches for managing the global commons; and how can multilateral institutions for health and development finance evolve.

Download or read book CHINA FOOD SECURITY AND AGRICULTURAL GOING GLOBAL written by Han Jun and published by American Academic Press. This book was released on 2022-11-21 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through decades of efforts, China has overall achieved self-sufficiency in food supply, which is the result of effective policies and measures adopted by the Chinese government. This book focuses on China’s food security strategy and agricultural going global strategy and goes into details on policies and measures for achieving domestic food security. It specially analyzes status and development trend of China’s corn industry since corn is the most sensitive grain variety that plays an important role as food, feed and raw material for bioenergy. It also studies overseas agricultural development potential for agricultural investment and cooperation globally. It finally elaborates China’s agricultural going global strategy, with specific cases to evaluate policy effect, in order to promote international cooperation in agriculture. The conclusions are that as the world’s most populated country, China should rely on its domestic production to ensure food supply. However, with intensified constraints on resources and environment, China should appropriately adjust its food security goals to ensure the basic self-sufficiency of cereals and rely more on global markets for non-cereal grain varieties. Looking to the future, China should establish a food security system that is efficient, open and sustainable through profound reform to increase its domestic food productivity, promote sustainable development of agriculture, and expand international cooperation in agriculture.

Download or read book The Tragedy of the Commodity written by Stefano B. Longo and published by Rutgers University Press. This book was released on 2015-06-25 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2017 Paul Sweezy Marxist Sociology Book Award from the American Sociological Association Although humans have long depended on oceans and aquatic ecosystems for sustenance and trade, only recently has human influence on these resources dramatically increased, transforming and undermining oceanic environments throughout the world. Marine ecosystems are in a crisis that is global in scope, rapid in pace, and colossal in scale. In The Tragedy of the Commodity, sociologists Stefano B. Longo, Rebecca Clausen, and Brett Clark explore the role human influence plays in this crisis, highlighting the social and economic forces that are at the heart of this looming ecological problem. In a critique of the classic theory “the tragedy of the commons” by ecologist Garrett Hardin, the authors move beyond simplistic explanations—such as unrestrained self-interest or population growth—to argue that it is the commodification of aquatic resources that leads to the depletion of fisheries and the development of environmentally suspect means of aquaculture. To illustrate this argument, the book features two fascinating case studies—the thousand-year history of the bluefin tuna fishery in the Mediterranean and the massive Pacific salmon fishery. Longo, Clausen, and Clark describe how new fishing technologies, transformations in ships and storage capacities, and the expansion of seafood markets combined to alter radically and permanently these crucial ecosystems. In doing so, the authors underscore how the particular organization of social production contributes to ecological degradation and an increase in the pressures placed upon the ocean. The authors highlight the historical, political, economic, and cultural forces that shape how we interact with the larger biophysical world. A path-breaking analysis of overfishing, The Tragedy of the Commodity yields insight into issues such as deforestation, biodiversity loss, pollution, and climate change.
