Available in PDF, EPUB and Kindle. Book excerpt: As razões que levaram ao desenvolvimento deste trabalho surgiram devido a grande transformação da agricultura brasileira que ao longo dos anos tem favorecido ao êxodo rural, incentivado por sua modernização excludente e parcial dos recursos para o trabalho com perspectivas de agravamento diante do cenário econômico mundial. Essas transformações foram: a globalização com abertura de mercado, a importância do meio ambiente e a revolução tecnológica. Todos esses fatores acabam por impulsionar a otimização das atividades nas propriedades rurais exigindo que cada vez se produza maiores quantidades com maior qualidade e com custos reduzidos. Essa exigência afasta cada vez mais o produtor rural de menor porte, geralmente composto por trabalho familiar que, por causa do êxodo rural, está envelhecendo e contando com um número significantemente menor de membros da família para o trabalho e, por outro lado, abre mais espaço para grandes produtores com poder aquisitivo maior. Já a evolução da tecnologia tem favorecido muito os produtores de grande porte, mas essa tecnologia não chegou aos pequenos e médios produtores na mesma proporção dos grandes. Hoje os produtores rurais de pequeno e médio porte ainda não podem contar com máquinas modernas, modulares e versáteis, que atendam na íntegra suas reais necessidades. Diante disso, a proposta desse trabalho foi desenvolver um protótipo conceitual de um módulo de potência para a agricultura, preparado para receber diferentes tecnologias de propulsão para o atendimento aos pequenos e médios produtores. No desenvolvimento da máquina foram definidas as especificações de projeto com base no resultado do questionário semi-estruturado, a fim de poder delinear o desenvolvimento do mesmo. A máquina (módulo de potência) foi projetada para ser utilizada em terrenos acidentados onde o risco de acidente por tombamento é grande. O trabalho foi desenvolvido até o projeto conceitual, em nível de um modelo eletrônico e de um modelo analógico. Para testar o conceito fez-se um processo de avaliação com parte dos agricultores e técnicos que participaram da especificação das necessidades. A avaliação dos modelos foi positiva recomendando a implementar para as outras fases do projeto. A percepção é que a estrutura modular permitiu ampliar as possibilidades de utilização da máquina e seu elemento de movimentação visa levar o conceito para a visão ecologicamente correta quanto a utilização de fontes de combustíveis renováveis.

Available in PDF, EPUB and Kindle. Book excerpt: An exploration of the Anthropocene and “a relentless reckoning of how we, as a species, got ourselves into the mess we’re in today” (The Wall Street Journal). Meteorites, mega-volcanoes, and plate tectonics—the old forces of nature—have transformed Earth for millions of years. They are now joined by a new geological force—humans. Our actions have driven Earth into a new geological epoch, the Anthropocene. For the first time in our home planet's 4.5-billion-year history a single species is increasingly dictating Earth’s future. To some the Anthropocene symbolizes a future of superlative control of our environment. To others it is the height of hubris, the illusion of our mastery over nature. Whatever your view, just below the surface of this odd-sounding scientific word—the Anthropocene—is a heady mix of science, philosophy, history, and politics linked to our deepest fears and utopian visions. Tracing our environmental impacts through time, scientists Simon Lewis and Mark Maslin reveal a new view of human history and a new outlook for the future of humanity in the unstable world we have created.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of recent developments in land, ecosystem, and water management in the Brazilian state of Rio de Janeiro. The state is located in the biodiversity hotspot of the Atlantic Forest (Mata Atlântica), a biome characterized by high biological diversity and endemism. At the same time the state of Rio de Janeiro emerged to one of the economic hubs in Latin America. This development process has been accompanied by population growth, industrialization, urbanization, as well as consumption and degradation of land and water resources. In the past years many efforts have been made to stop or at least slow down these degradation processes and restore degraded environments with the overall goal to bring together sustainable management of natural resources, nature conservation, and economic development. An overview is provided of the different strategies and tools that have been developed in the fields of agriculture, ecosystem management and biodiversity, integrated water management, land restoration, disaster risk reduction and climate change adaptation, as well as environmental governance and economic instruments. This book covers a wide spectrum from applied research to science‐policy interfaces, planning concepts, and technical tools and has a model character for other rural areas in Latin America. Target groups are scientists, practitioners, policy makers and graduate students in the field of environmental management. The different chapters are written by researchers and practitioners of the German‐Brazilian project INTECRAL (Integrated Eco Technologies and Services for a Sustainable Rural Rio de Janeiro), the rural development program Rio Rural under the state secretary for agriculture and animal husbandry, as well as invited scientists from Brazilian universities and research institutes. It bridges existing gaps between science, policies, and practice in rural development.

Book excerpt: bookdown: Authoring Books and Technical Documents with R Markdown presents a much easier way to write books and technical publications than traditional tools such as LaTeX and Word. The bookdown package inherits the simplicity of syntax and flexibility for data analysis from R Markdown, and extends R Markdown for technical writing, so that you can make better use of document elements such as figures, tables, equations, theorems, citations, and references. Similar to LaTeX, you can number and cross-reference these elements with bookdown. Your document can even include live examples so readers can interact with them while reading the book. The book can be rendered to multiple output formats, including LaTeX/PDF, HTML, EPUB, and Word, thus making it easy to put your documents online. The style and theme of these output formats can be customized. We used books and R primarily for examples in this book, but bookdown is not only for books or R. Most features introduced in this book also apply to other types of publications: journal papers, reports, dissertations, course handouts, study notes, and even novels. You do not have to use R, either. Other choices of computing languages include Python, C, C++, SQL, Bash, Stan, JavaScript, and so on, although R is best supported. You can also leave out computing, for example, to write a fiction. This book itself is an example of publishing with bookdown and R Markdown, and its source is fully available on GitHub.

Book excerpt: In Brazil, sugarcane ethanol supplied, in 2009, 17.6 % of the energy for land transportation (excluding railroads)and about 55% of the total energy supplied by liquid fuel for Otto cycle engines. Besides the lower production costs ethanol produced from sugarcane in Brazil has another important advantage: in Central-South Brazil only 1 unit of fossil energy is used for each 8-9 units of energy produced by ethanol from sugarcane. Carbon emissions reduction also benefits from sugarcane ethanol: for each cubic meter of ethanol used as fuel, there is net saving of around 2 t CO2 not emitted to the atmosphere while, at the same time, no SO2 is emitted. Sugarcane was introduced in Brazil in 1532. The "Brazilian model" of producing concomitantly sugar and ethanol, brought important technical benefits and made possible an outstanding increase in the competitiveness in the international market for sugar and ethanol. Today about 50% of the sucrose of sugarcane produced in the country is directed to the production of sugar while another half is used to produce Ethanol. Industrial and academic R&D has helped to increase the productivity of ethanol steadily over the past 35 years, at a rate of 3.2% per year. Productivity gains implied savings of planted area by a factor of 2.6. In 2009/2010 the area planted with sugarcane for Ethanol production was 4.2 Mha, amounting to 1% of the total arable land available in Brazil. About 60% of the Ethanol produced in Brazil comes from the State of Sao Paulo, where the productivity is the highest (around 86 t/ha.year). Most of the recent expansion is happening in the center-west region of the country, in degraded pasture lands. The FAPESP Program for Research on Bioenergy, BIOEN, aims at articulating public and private R&D, using academic and industrial laboratories to advance and apply knowledge in fields related to ethanol production in Brazil. The BIOEN Program has a solid core for supporting academic exploratory research activities that will generate new knowledge and form scientists and professionals essential for advancing industry capacity in ethanol related technologies. On top of this, BIOEN includes partnerships with industry for cooperative R&D activities between industrial and academic laboratories, which are to be co-funded by FAPESP and industry.Federal agencies, such as CNPq, will also co-fund the research.

This book was released on 2006-05-02 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States is viewed by the world as a country with plenty of food, yet not all households in America are food secure, meaning access at all times to enough food for an active, healthy life. A proportion of the population experiences food insecurity at some time in a given year because of food deprivation and lack of access to food due to economic resource constraints. Still, food insecurity in the United States is not of the same intensity as in some developing countries. Since 1995 the U.S. Department of Agriculture (USDA) has annually published statistics on the extent of food insecurity and food insecurity with hunger in U.S. households. These estimates are based on a survey measure developed by the U.S. Food Security Measurement Project, an ongoing collaboration among federal agencies, academic researchers, and private organizations. USDA requested the Committee on National Statistics of the National Academies to convene a panel of experts to undertake a two-year study in two phases to review at this 10-year mark the concepts and methodology for measuring food insecurity and hunger and the uses of the measure. In Phase 2 of the study the panel was to consider in more depth the issues raised in Phase 1 relating to the concepts and methods used to measure food security and make recommendations as appropriate. The Committee on National Statistics appointed a panel of 10 experts to examine the above issues. In order to provide timely guidance to USDA, the panel issued an interim Phase 1 report, Measuring Food Insecurity and Hunger: Phase 1 Report. That report presented the panel's preliminary assessments of the food security concepts and definitions; the appropriateness of identifying hunger as a severe range of food insecurity in such a survey-based measurement method; questions for measuring these concepts; and the appropriateness of a household survey for regularly monitoring food security in the U.S. population. It provided interim guidance for the continued production of the food security estimates. This final report primarily focuses on the Phase 2 charge. The major findings and conclusions based on the panel's review and deliberations are summarized.
