Book Synopsis Sustainable Agriculture and the Environment in the Humid Tropics by : National Research Council
Download or read book Sustainable Agriculture and the Environment in the Humid Tropics written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainforests are rapidly being cleared in the humid tropics to keep pace with food demands, economic needs, and population growth. Without proper management, these forests and other natural resources will be seriously depleted within the next 50 years. Sustainable Agriculture and the Environment in the Humid Tropics provides critically needed direction for developing strategies that both mitigate land degradation, deforestation, and biological resource losses and help the economic status of tropical countries through promotion of sustainable agricultural practices. The book includes: A practical discussion of 12 major land use options for boosting food production and enhancing local economies while protecting the natural resource base. Recommendations for developing technologies needed for sustainable agriculture. A strategy for changing policies that discourage conserving and managing natural resources and biodiversity. Detailed reports on agriculture and deforestation in seven tropical countries.
Book Synopsis Natural Enemies of Insect Pests in Neotropical Agroecosystems by : Brígida Souza

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to address the importance of natural enemies and functional diversity for biological control in Neotropical agroecosystems. Several aspects related to the conservation of natural enemies, such as vegetation design and climate change, are discussed in Part 1 and the bioecology of several insects groups used in biological control in Latin America is presented in Part 2. Part 3 is devoted to mass production of natural enemies while Part 4 describes how these insects have been used to control of pests in major crops, forests, pasture, weeds and plant diseases. Lastly, Part 5 reports Latin-American experiences of integration of biological in pest management programs.

Book Synopsis Proximal Soil Sensing by : Raphael A. Viscarra Rossel
Download or read book Proximal Soil Sensing written by Raphael A. Viscarra Rossel and published by Springer Science & Business Media. This book was released on 2010-07-25 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.

Book Synopsis Agriculture and Industry in Brazil by : Albert Fishlow
Download or read book Agriculture and Industry in Brazil written by Albert Fishlow and published by Columbia University Press. This book was released on 2020-08-04 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture and Industry in Brazil is a study of the economics of Brazilian agriculture and industry, with a special focus on the importance of innovation to productivity growth. Albert Fishlow and José Eustáquio Ribeiro Vieira Filho examine technological change in Brazil, highlighting the role of public policy in building institutions and creating an innovation-oriented environment. Fishlow and Vieira Filho tackle the theme of innovation from various angles. They contrast the relationship between state involvement and the private sector in key parts of the Brazilian economy and compare agricultural expansion with growth in the oil and aviation sectors. Fishlow and Vieira Filho argue that modern agriculture is a knowledge-intensive industry and its success in Brazil stems from public institution building. They demonstrate how research has played a key role in productivity growth, showing how prudent innovation policies can leverage knowledge not only within a particular company but also across whole sectors of the economy. The book discusses whether and how Brazil can serve as a model for other middle-income countries eager to achieve higher growth and a more egalitarian distribution of income. An important contribution to comparative, international, and development economics, Agriculture and Industry in Brazil shows how the public success in agriculture became a prototype for advance elsewhere.
Book Synopsis Tapping the Green Market by : Abraham Guillen
Download or read book Tapping the Green Market written by Abraham Guillen and published by Routledge. This book was released on 2012-08-21 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a rapidly growing interest in, and demand for, non-timber forest products (NTFPs). They provide critical resources across the globe fulfilling nutritional, medicinal, financial and cultural needs. However, they have been largely overlooked in mainstream conservation and forestry politics. This volume explains the use and importance of certification and eco-labelling for guaranteeing best management practices of non-timber forest products in the field. Using extensive case studies and global profiles of non-timber forest products, this work not only seeks to further our comprehension of certification processes but also broaden understanding of non-timber forest product management, harvesting and marketing. It should be useful to forest managers, policy-makers and conservation organizations as well as for academics in these areas.
Book Synopsis The Biogeochemistry of the Amazon Basin by : Michael E. McClain
Download or read book The Biogeochemistry of the Amazon Basin written by Michael E. McClain and published by Oxford University Press. This book was released on 2001-11-08 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a complex assemblage of largely intact ecosystems that support the earth's greatest diversity of life, the Amazon basin is a focal point of international scientific interest. And, as development and colonization schemes transform the landscape in increasing measure, scientists from around the world are directing attention to questions of regional and global significance. Some of these qustions are: What are the fluxes of greenhouse gases across the atmospheric interface of ecosystems? How mush carbon is stored in the biomass and soils of the basin? How are elements from the land transferred to the basin's surface waters? What is the sum of elements transferred from land to ocean, and what is its marine "fate"? This book of original chapters by experts in chemical and biological oceanography, tropical agronomy and biology, and the atmospheric sciences will address these and other important questions, with the aim of synthesizing the current knowledge of biochemical processes operating within and between the various ecosystems in the Amazon basin.
