Download or read book The Fire Next Door written by Ted Galen Carpenter and published by Cato Institute. This book was released on 2012-10-09 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Mexican government initiated a military offensive against its country’s powerful drug cartels in December 2006, some 50,000 people have perished and the drugs continue to flow. In The Fire Next Door, Ted Galen Carpenter boldly conveys the growing horror overtaking Mexico and makes the case that the only effective strategy for the United States is to abandon its failed drug prohibition policy, thus depriving drug cartels of financial resources.
Download or read book Evaluation of Soil Organic Matter Models written by David S. Powlson and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter (SOM) represents a major pool of carbon within the biosphere, roughly twice than in atmospheric CO2. SOM models embody our best understanding of soil carbon dynamics and are needed to predict how global environmental change will influence soil carbon stocks. These models are also required for evaluating the likely effectiveness of different mitigation options. The first important step towards systematically evaluating the suitability of SOM models for these purposes is to test their simulations against real data. Since changes in SOM occur slowly, long-term datasets are required. This volume brings together leading SOM model developers and experimentalists to test SOM models using long-term datasets from diverse ecosystems, land uses and climatic zones within the temperate region.

Download or read book Soil Conditions and Plant Growth written by Peter J. Gregory and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building on the extremely successful and popular Russell’s Soil Conditions and Plant Growth, Wiley-Blackwell is pleased to publish this completely revised and updated edition of the soil science classic. Covering all aspects of the interactions between plant and soil, Peter Gregory and Stephen Nortcliff, along with their team of internationally-known and respected authors, provide essential reading for all students and professionals studying and working in agriculture and soil science. Subject areas covered range from crop science and genetics; soil fertility and organic matter; nitrogen and phosphoros cycles and their management; properties and management of plant nutrients; water and the soil physical environment and its management; plants and change processes in soils; management of the soil/plant system; and new challenges including food, energy and water security in a changing environment. Providing a very timely account on how better to understand and manage the many interactions that occur between soils and plants, Soil Conditions and Plant Growth is sure to become the book of choice - as a recommended text for students and as an invaluable reference for those working or entering into the industry. An essential purchase for all universities and research establishments where agricultural, soil, and environmental sciences are studied and taught.
Download or read book The End of Development written by Andrew Brooks and published by Zed Books Ltd.. This book was released on 2017-05-15 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why did some countries grow rich while others remained poor? Human history unfolded differently across the globe. The world is separated in to places of poverty and prosperity. Tracing the long arc of human history from hunter gatherer societies to the early twenty first century in an argument grounded in a deep understanding of geography, Andrew Brooks rejects popular explanations for the divergence of nations. This accessible and illuminating volume shows how the wealth of ‘the West’ and poverty of ‘the rest’ stem not from environmental factors or some unique European cultural, social or technological qualities, but from the expansion of colonialism and the rise of America. Brooks puts the case that international inequality was moulded by capitalist development over the last 500 years. After the Second World War, international aid projects failed to close the gap between ‘developed’ and ‘developing’ nations and millions remain impoverished. Rather than address the root causes of inequality, overseas development assistance exacerbate the problems of an uneven world by imposing crippling debts and destructive neoliberal policies on poor countries. But this flawed form of development is now coming to an end, as the emerging economies of Asia and Africa begin to assert themselves on the world stage. The End of Development provides a compelling account of how human history unfolded differently in varied regions of the world. Brooks argues that we must now seize the opportunity afforded by today’s changing economic geography to transform attitudes towards inequality and to develop radical new approaches to addressing global poverty, as the alternative is to accept that impoverishment is somehow part of the natural order of things.

Download or read book Biomethanization of the Organic Fraction of Municipal Solid Wastes written by J. Mata-Alvarez and published by IWA Publishing. This book was released on 2002-08-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomethanization of the Organic Fraction of Municipal Solid Wastes is a comprehensive introduction to both the fundamentals and the more practical aspects of the anaerobic digestion of organic solid wastes, particularly those derived from households, that is, the organic fraction of municipal solid wastes (OFMSW). It can be used as a textbook for specialized courses and also as a guide for practitioners. In the first part, the book covers the relevant aspects of anaerobic digestion (AD) of organic wastes. The fundamentals and kinetic aspects of AD are reviewed with particular emphasis on the aspects related to solid wastes. This introduction is necessary to have a comprehensive view of the AD process and to understand the practical principles as well as the origin of possible problems arising from the management of the process. Chapter 2 emphasizes the role of kinetics in designing the reactor, paying special attention to existing models, particularly the dynamic ones. Through this introduction, it is intended to facilitate the technology transfer from laboratory or pilot plant experiences to full-scale process, in order to implement improvements in current digesters. Laboratory methods are described for the analysis and optimization of reactor performance, such as methanogenic activity tests or experimental evaluation of the biodegradation kinetics of solid organic waste. The different reaction patterns applied to industrial reactors are outlined. Industrial reactors are classified in accordance with the system they use, pointing out advantages and limitations. Co-digestion, enabling the co-treatment of organic wastes of different origin in a more economically feasible way, is described in detail. Examples of co-digestion are given, with OFMSW as a base-substrate. Finally, full-scale co-digestion plants are discussed. Various types (mechanical, biological, physico-chemical) of pre-treatment to increase the biodegradability, and thus the yields of the process, are reviewed in detail. The use of the fermentation products of anaerobic digesters for biological nutrient removal processes in wastewater treatment plants is described. This constitutes an example of integrated waste management, a field in which both economic and technical advances can be achieved. Balances are given to justify the approach, and a full-scale case study is presented. The important topic of economics and the ecological advantages of the process are emphasized. The use of compost, the integration with composting technology, and advantages over other technologies are detailed in the framework of an environmental impact assessment of biowaste treatment. Finally, the anaerobic digestion of MSW in landfills is reviewed in detail, with emphasis on landfill process enhancement and strategies for its application.
