Download or read book Soil Quality for Crop Production and Ecosystem Health written by E.G. Gregorich and published by Elsevier. This book was released on 1997-11-10 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is a complex body that exists as many types, each with diverse properties that may vary widely across time and space as a function of many factors. This complexity makes the evaluation of soil quality much more challenging than that of water or air quality. Evaluation of soil quality now considers environmental implications as well as economic productivity, seeking to be more holistic in its approach.Thus, soil quality research draws from a wide range of disciplines, blending the approaches of biologists, physicists, chemists, ecologists, economists and agronomists, among others.This book presents a broad perspective of soil quality that includes these various perspectives and gives a strong theoretical basis for the assessment of soil quality.A short glossary provides definitions for terms used throughout the book.

Download or read book Transforming the Rural Nonfarm Economy written by Steven Haggblade and published by Intl Food Policy Res Inst. This book was released on 2007-11-16 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contrary to conventional wisdom that equates rural economies with agriculture, rural residents in developing countries often rely heavily on activities other than farming for their income. Indeed, nonfarm work accounts for between one-third and one-half of rural incomes in the developing world. In recent years, accelerating globalization, increasing competition from large businesses, expanding urban markets for rural goods and services, and greater availability of information and communication technology have combined to expose rural nonfarm businesses to new opportunities as well as new risks. By examining these rapid changes in the rural nonfarm economy, international experts explore how the rural nonfarm economy can contribute to overall economic growth in developing countries and how the poor can participate in this rapidly evolving segment of the economy. The authors review an array of recent studies of the rural nonfarm economy in order to summarize existing empirical evidence, explore policy implications, and identify future research priorities. They examine the varied scale, structure, and composition of the rural nonfarm economy, as well as its relationship with agricultural and urban enterprises. And they address key questions about the role of public intervention in the rural nonfarm economy and how the rural poor can participate in and navigate the rapid transition underway in rural areas. The contributors offer new insights to specialists in rural development and to others interested in overall economic development.

Download or read book Fresh Tracks in the Forest Assessing Incipient Payments for Environmental Services Initiatives in Bolivia written by Nina Robertson and published by CIFOR. This book was released on 2005-01-01 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Payments for Environmental Services (PES) are being considered worldwide with great interest and expectation. Proposals to create agreements in which beneficiaries of environmental services pay landowners directly for the provision or protection of these services are innovative and promising. But what real PES experiences are actually out there? This work assesses a range of PES or PES-type experiences in one country, Bolivia, in the fields of carbon sequestration, protection of watershed services, biodiversity and aesthetic landscape values. The report concludes that while none of the generally young initiatives adhere fully to the principle of PES as developed in the theoretical literature, many experiment with some of the relevant PES mechanisms. Protection of watersheds and landscape values are the most common types, though the implementing intermediaries often have underlying biodiversity-protection goals. Main obstacles to PES implementation include ideological resistance against the PES concept, the difficulty of building trust between buyers and sellers, and limited willingness to pay on behalf of service users. During their relatively short lifetime, basically all initiatives had been successful in making service sellers (PES recipients) better off in economic terms, while the effectiveness in achieving environmental objectives and securing positive social impacts so far remained more variable. In some cases, redesigning these initiatives to bring them closer to the full PES principles could also enable them to more effectively achieve positive environmental and livelihood outcomes.
Download or read book The North American Mosaic written by Commission for Environmental Cooperation (Montréal, Québec). Secretariat and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Download or read book Linking Social and Ecological Systems written by Fikret Berkes and published by Cambridge University Press. This book was released on 2000-04-13 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is usually the case that scientists examine either ecological systems or social systems, yet the need for an interdisciplinary approach to the problems of environmental management and sustainable development is becoming increasingly obvious. Developed under the auspices of the Beijer Institute in Stockholm, this new book analyses social and ecological linkages in selected ecosystems using an international and interdisciplinary case study approach. The chapters provide detailed information on a variety of management practices for dealing with environmental change. Taken as a whole, the book will contribute to the greater understanding of essential social responses to changes in ecosystems, including the generation, accumulation and transmission of ecological knowledge, structure and dynamics of institutions, and the cultural values underlying these responses. A set of new (or rediscovered) principles for sustainable ecosystem management is also presented. Linking Social and Ecological Systems will be of value to natural and social scientists interested in sustainability.
Download or read book Biological Wastewater Treatment written by Mogens Henze and published by IWA Publishing (International Water Assoc). This book was released on 1881 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: For information on the online course in Biological Wastewater Treatment from UNESCO-IHE, visit: http://www.iwapublishing.co.uk/books/biological-wastewater-treatment-online-course-principles-modeling-and-design Over the past twenty years, the knowledge and understanding of wastewater treatment have advanced extensively and moved away from empirically-based approaches to a first principles approach embracing chemistry, microbiology, physical and bioprocess engineering, and mathematics. Many of these advances have matured to the degree that they have been codified into mathematical models for simulation with computers. For a new generation of young scientists and engineers entering the wastewater treatment profession, the quantity, complexity and diversity of these new developments can be overwhelming, particularly in developing countries where access is not readily available to advanced level tertiary education courses in wastewater treatment. Biological Wastewater Treatment addresses this deficiency. It assembles and integrates the postgraduate course material of a dozen or so professors from research groups around the world that have made significant contributions to the advances in wastewater treatment. The book forms part of an internet-based curriculum in biological wastewater treatment which also includes: Summarized lecture handouts of the topics covered in book Filmed lectures by the author professors Tutorial exercises for students self-learning Upon completion of this curriculum the modern approach of modelling and simulation to wastewater treatment plant design and operation, be it activated sludge, biological nitrogen and phosphorus removal, secondary settling tanks or biofilm systems, can be embraced with deeper insight, advanced knowledge and greater confidence.
