Available in PDF, EPUB and Kindle. Book excerpt: Em propriedades com recursos hídricos escassos e/ou com topografia muito ondulada, os sisstemas de irrigação convencionais tem seu emprego limitado. Com adaptações feitas pelo CPATSA?EMBRAPA, essas propriedades poderão ser exploradas pelo sistema de irrigação por mangueira utilizando microbacias. Este sistema apresenta as seguintes características: condução da água através de tubulação; aplicação localizada da água através de mangueiras flexíveis; funciona sob condições de baixa e média pressão: aproveitamento de fontes de água com pequenas vazões ou pequenos volumes; não requer a filtragem da água de irrigação; aproveita a mão-de-obra familiar, simples quanto a instalação e ao manejo; evita perdas de água por escoamento superficial e apresenta uma alta eficiência de irrigação. Este sistema de irrigação destina-se a exploração de fruteiras. O custo de investimento deste sistema de irrigação, sob condições de baixa pressão (sem necessidade de bombeamento) representa em média 38% do custo de investimento do sistema de irrigação por aspersão. Sob condição de bombeamento, o custo de investimento desse sistema se equivale ao do sistema de irrigação por aspersão, mas que permite a irrigação em terrenos com declividades bastante elevadas, que normalmente, limitam o emprego dos sistemas de irrigação convencionais.

Book excerpt: The factors affecting the presence and growth of micro-organisms in piped networks are reviewed in this book, as are the practices of water supply organisations that can directly or indirectly influence their presence and growth. The information and conclusions are intended for policy makers and those responsible for formulating "Water Safety Plans" for the supply of drinking-water. It is also relevant to engineers and scientists who are responsible for water supply planning, operations and monitoring. The review shows that there are often public health reasons for adopting a more proactive approach to many of the traditional practices used in designing, operating and maintaining distribution networks, and to modifying the composition of the water that is fed into the network. Contents include the following topics: The microbiology of piped distribution systems and public health Composition of treated waters to minimise potential for microbiological changes Design and operation of distribution networks. Planned maintenance and survey of distribution systems Precautions during construction and repairs Small animals in drinking water distribution systems Risk management for distribution systems

Available in PDF, EPUB and Kindle. Book excerpt: In February 1813 the British frigate Phoebe set out on a secret mission that would involve sailing halfway around the world to attack American settlements in the Pacific Northwest. The United States, frustrated at the treatment of its shipping by the combatants in the Napoleonic Wars, had finally opened hostilities against the British in the previous June. From the American perspective the War of 1812 began with disasters in its invasion of Canada, but against all expectations the infant US Navy had scored significant victories at sea. The most strategically significant of these was the campaign by the frigate USS Essex, which had almost annihilated the lucrative British whaling trade in the south Pacific. Therefore, Phoebe was diverted to hunt down and destroy this highly successful commerce-raider. After an epic search, Phoebe tracked her prey to neutral Valparaiso where the American frigate was blockaded and,in a very bloody battle, eventually captured. The American captain, David Porter, published a self-serving account of his actions which ever since has mired the battle in controversy, so this British naval eyewitness account is an important counter-balance. It is one of the lesser-known campaigns of a war which is currently celebrating its bicentenary, but its inherent drama inspired the plot of Patrick O'Brian's novel The Far Side of the World, although in its movie adaptation Master & Commander the American frigate is transformed into a French privateer.

Available in PDF, EPUB and Kindle. Book excerpt: The Urban and Regional Planning Reader draws together the very best of classic and contemporary writings to illuminate the planning of cities and metropolitan areas. Forty-seven generous selections include contributions from Lewis Mumford, Jane Jacobs, Ian McHarg, Paul Davidoff, Charles Harr, Susan Fainstein and Charles J. Hoch through to Timothy Beatley; Jonathan Barnett, Alex Garvin, Tom Daniels, Andres Duany and Barbara Faga. The variety and wide selection of readings offers one of the most innovative amalgamations of planning research and practice. The Reader lays out the context, range of concerns, history, methods and key topics for twenty-first century urban and regional planning. Sections on the world of planning, history and theory, classic readings, practice and current issues include writings with a focus on the distribution of space and place, essays on housing, transportation design, environment, community development, the effects of cultural diversity and information technology on land use and other topics. It displays the techniques used to direct and control growth, including zoning, master planning, public budgeting and citizen participation. It explores different types of plans distinguished by their scale and reference type. It references analytical and presentation techniques and outlines ethical issues confronting planners. This Urban and Regional Planning Reader provides an essential resource, for students of planning, drawing together important but widely dispersed writings and the associated bibliography is a resource which enables deeper investigations. The synthesis is also valuable for lecturers and researches in the area and the pertinent editorial commentaries preceding each entry not only demonstrate its significance, but also outline the issue surrounding the topic.

Available in PDF, EPUB and Kindle. Book excerpt: Carrot City is a collection of ideas, both conceptual and realized, that use design to enable sustainable food production, helping to reintroduce urban agriculture to our cities. Focusing on the need and desire to grow food within the city to supply food from local sources, the contributions of architecture, landscape design, and urban design are explored. Forty projects demonstrate how the production of food can lead to visually striking and artistically interesting solutions that create community and provide inhabitants with immediate access to fresh, healthful ingredients. The authors show how city planning and architecture that considers food production as a fundamental requirement of design result in more community gardens, greenhouses tucked under raised highways, edible landscapes in front yards in place of resource-devouring lawns, living walls that bring greenery into dense city blocks, and productive green roofs on schools and large apartment blocks that can be tended and harvested by students and residents alike.

Available in PDF, EPUB and Kindle. Book excerpt: Shows how to combine the forces of ecological science and participatory democracy to design urban landscapes that enable us to act as communities, are resilient rather than imperiled, and touch our hearts. Over the last fifty years, the process of community building has been lost in the process of city building. City and suburban design divides us from others in our communities, destroys natural habitats, and fails to provide a joyful context for our lives. In Design for Ecological Democracy, Randolph Hester proposes a remedy for our urban anomie. He outlines new principles for urban design that will allow us to forge connections with our fellow citizens and our natural environment. He demonstrates these principles with abundantly illustrated examples—drawn from forty years of design and planning practice—showing how we can design cities that are ecologically resilient, that enhance community, and that give us pleasure. Hester argues that it is only by combining the powerful forces of ecology and democracy that the needed revolution in design will take place. Democracy bestows freedom; ecology creates responsible freedom by explaining our interconnectedness with all creatures. Hester's new design principles are founded on three fundamental issues that integrate democracy and ecology: enabling form, resilient form, and impelling form. Urban design must enable us to be communities rather than zoning-segregated enclaves and to function as informed democracies. A simple bench at a centrally located post office, for example, provides an opportunity for connection and shared experience. Cities must be ecologically resilient rather than ecologically imperiled, adaptable to the surrounding ecology rather than dependent on technological fixes. Resilient form turns increased urban density, for example, into an advantage. And cities should impel us by joy rather than compel us by fear; good cities enrich us rather than limit us. Design for Ecological Democracy is essential reading for designers, planners, environmentalists, community activists, and anyone else who wants to improve a local community.
