This book was released on 2021-06-14 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Como externalidades se distinguen aquellos aspectos ambientales no deseados en los sistemas de producción agropecuarios que en últimas afectan su sostenibilidad; por ejemplo, la pérdida de la agrobiodiversidad por simplificación del germoplasma, la degradación del suelo por uso excesivo de maquinaria y aplicación de fertilizantes sintéticos, la contaminación del agua y el aire por solubilidad de moléculas empleadas en el manejo de arvenses, plagas y enfermedades, entre otros, que limitan su reproducibilidad en el tiempo, reducen los beneficios económicos obtenidos por los produc-tores y, en últimas, ocasionan su deserción del sector. No se trata solo de analizar cómo las prácticas de agricultura convencional afectan estos sistemas de producción, sino también de evaluar alternativas de manejo que reduzcan estos impactos, basadas en la simulación de procesos que ocurren naturalmente en los ecosistemas. Entre estos procesos se destacan el aprovechamiento de la energía solar para generación de biomasa, sobre todo por ser Colombia un país de trópico, el incremento de la diversidad en sistemas de cultivo aprovechando las relaciones sinérgicas entre las especies, el manejo a favor de los agroecosistemas de los ciclos biogeoquímicos de elementos como el carbono, nitrógeno, fósforo y potasio, el incentivo de los organismos del suelo como transformadores de materia orgánica, la estabilización y habilitación de residuos como abonos y sustratos orgánicos mediante procesos de compostaje y el aprovechamiento de materiales vegetales fibrosos para elaboración de materiales de construcción con el fin de ser incorporados en la infraestructura rural. Por esta razón el presente libro se titula Relaciones agroambientales en sistemas productivos rurales. La redacción del libro se basa en el lenguaje técnico-científico y pretende abarcar un gran número de lectores que incluyen agricultores, estudiantes de las ciencias agropecuarias y ambientales, tomadores de decisiones en el sector agropecuario y la comunidad académica en general, con miras de aportar al desarrollo de masa crítica y servir de referencia para otras investigaciones enfocadas al desarrollo de una agricultura más limpia y la producción sostenible de alimentos.
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 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 Making Parks Work written by John Terborgh and published by . This book was released on 2002-03 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most scientists and researchers working in tropical areas are convinced that parks and protected areas are the only real hope for saving land and biodiversity in those regions. Rather than giving up on parks that are foundering, ways must be found to strengthen them, and Making Parks Work offers a vital contribution to that effort. Focusing on the "good news" -- success stories from the front lines and what lessons can be taken from those stories -- the book gathers experiences and information from thirty leading conservationists into a guidebook of principles for effective management of protected areas. The book: offers a general overview of the status of protected areas worldwide presents case studies from Africa, Latin America, and Asia written by field researchers with long experience working in those areas analyzes a variety of problems that parks face and suggests policies and practices for coping with those problems explores the broad philosophical questions of conservation and how protected areas can -- and must -- resist the mounting pressures of an overcrowded world Contributors include Mario Boza, Katrina Brandon, K. Ullas Karanth, Randall Kramer, Jeff Langholz, John F. Oates, Carlos A. Peres, Herman Rijksen, Nick Salafsky, Thomas T. Struhsaker, Patricia C. Wright, and others.
Download or read book Soil and Sediment Remediation written by Piet Lens and published by IWA Publishing. This book was released on 2005-09-30 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Download or read book Ecological Indicators for the Nation written by National Research Council and published by National Academies Press. This book was released on 2000-04-12 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental indicators, such as global temperatures and pollutant concentrations, attract scientists' attention and often make the headlines. Equally important to policymaking are indicators of the ecological processes and conditions that yield food, fiber, building materials and ecological "services" such as water purification and recreation. This book identifies ecological indicators that can support U.S. policymaking and also be adapted to decisions at the regional and local levels. The committee describes indicators of land cover and productivity, species diversity, and other key ecological processesâ€"explaining why each indicator is useful, what models support the indicator, what the measured values will mean, how the relevant data are gathered, how data collection might be improved, and what effects emerging technologies are likely to have on the measurements. The committee reviews how it arrived at its recommendations and explores how the indicators can contribute to policymaking. Also included are interesting details on paleoecology, satellite imagery, species diversity, and other aspects of ecological assessment. Federal, state, and local decision-makers, as well as environmental scientists and practitioners, will be especially interested in this new book.
