This book was released on 2013-11-27 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three important studies were initiated in the 1970s to investigate the relation ship between climatic variations and agriculture: by the National Delcnse University (1980) on Crop Yields and Climate Change to the Year 2000, by the U.s. Department of Transportation (1975) on Impacts of Climatic Change on the Biosphere and by the U.S. Department of Energy (1980) on Environmental and Societal Consequences of a Possible CO -Induced Climatic Change (the ClAP 2 study). These were pioneering projects in a young field. Their emphasis was on measuring likely impacts of climatic variations rather than on evaluating possible responses, and they focused on first-order impacts (e.g., on crop yields) rather than on higher-order effects on society. A logical next step was to look at higher-order effects and potential responses, as part of a more integrated approach to impact assessment. This was undertaken by the World Climate Impact Program (WCIP), which is directed by the United Nations Environment Program (UNEP). The WCIP is one of four aspects of the World Climate Program that was initiated in 1979. At a meeting in 1982, the Scientific Advisory Committee of WCIP accepted, in broad terms, a proposal from the International Institute for Applied Systems Analysis (IIASA) for an integrated climate impact assessment, with the proviso that the emphasis be on impacts in the agricultural sector. Martin Parry was asked to design and direct the project at IIASA. Funding was provided by UNEP, IIASA, the Austrian Government and the United Nations University.
Download or read book Soil erosion the greatest challenge for sustainable soil management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-05-16 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.
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 Soil Erosion written by Arthur J. Fournier and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil erosion is perceived as a major and widespread form of soil degradation and it has large environmental and economic impacts at different scales, especially in agricultural areas. Even though erosion originally is a natural process, influenced by physical factors, current human interventions in the landscape often accelerate natural erosion rates tremendously. Consequently, social, economic and political factors are decisive in determining soil erosion risk. This book gathers and presents current research from around the globe in the study of soil erosion, including research on erosion measurements and estimates with reference to water erosion in mountain environments; radiocaesium as a tool of erosion studies; and mitigation strategies to counteract soil erosion.

Download or read book Desertification written by Monique Mainguet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controversial, and often discussed with passion and vehemence, desertification is a problem on whose solution the survival of millions of humans is dependent. This book aims at an understanding of what is commonly called "desertification" - a term which has a connotation of irreversibility, spreading and emergence of desert-like landscapes: "land degradation" is proposed to replace it. The purpose is to present what has happened in reality, and what might be done. Illustrative worldwide analyses allow a more realistic evaluation of global land degradation. Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in a decrease in soil productivity and eventually land degradation. The benefit to the reader is an awareness of the ecozones which have undergone the most severe land degradation, and a global overview of the phenomena, mechanisms and existing solutions.
Download or read book Food And Natural Resources written by David Pimentel and published by Elsevier. This book was released on 2012-12-02 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food and Natural Resources provides an understanding of the interdependency of food and natural resources that affect society. It is hoped that through these discussions a more complete understanding of these timely issues will emerge. This base of knowledge will help individuals and government leaders develop and implement the types of programs that will result in the effective use and management of land, water, energy, and biological resources for improved food production and a higher standard of living for everyone. The book begins by examining the intrinsic dynamics of natural ecosystems—especially the land, water, atmosphere, energy, and biological components. This is followed by chapters on the availability and interrelationships between population size, arable land, water, energy, and other biological resources; the loss of wild species of plants and animals; the availability of agricultural land for crops and livestock; and the impact of land degradation on food and other resources. Subsequent chapters discuss water use in agriculture; the mechanization of agriculture and food production; the principles and practices that can make agriculture environmentally and economically sound and sustainable; and the impact of population growth on the environment and food supply.
