Download or read book Distribuição do sistema radicular e consumo de água da bananeira irrigada por microaspersão written by C. M. C. Ramos and published by . This book was released on 2001 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: O semi-árido nordestino é uma região propícia ao desenvolvimento da agricultura irrigada, em particular a fruticultura. Na região do Sub-Médio São Francisco, o cultivo da bananeira vem crescendo nos últimos anos. Com o objetivo de obter dados para maximizar a eficiência do manejo da irrigação, foi instalado, em 1999, experimento com a cultura da bananeira (Musa AAB, subgrupo Prata, var. Pacovan), irrigada por um sistema de microaspersão, na estação experimental da Embrapa -Semi- Árido, em Petrolina -PE, onde foi avaliada a distribuição radicular e quantificadas a área foliar e a evapotranspiração real da cultura durante o primeiro ciclo. A avaliação do sistema radicular das plantas foi feita através da análise de imagens digitais, para determinação de área e comprimento das raízes. As determinações da área foliar da bananeira foram realizadas aos 65, 123 e 184 dias depois do plantio (DAP), quando as plantas entraram em plena floração. A evapotranspiração real (ETr) foi calculada pelo método do balanço hídrico da água no solo, realizado em determinados períodos ao longo do ciclo da cultura. Aproximadamente 80% das raízes da bananeira distribuíram-se até 0,80 m de distância do pseudocaule no sentido da entrelinha, enquanto 88% da área total das raízes se concentrou até a profundidade de 0,60 m, em um solo de textura arenosa, aos 371 DAP. A área foliar da "planta-mãe" da bananeira, no primeiro ciclo, teve sua maior taxa de crescimento entre os 120 e 180 DAP, totalizando uma área de 11,3 m2 aos 245 DAP. O consumo de água da bananeira foi calculado entre o primeiro mês depois do plantio das mudas até a colheita e observou-se consumo de 1.401 mm, com evapotranspiração diária máxima de 6,2 mm/dia e média de 3,3 mm/dia no período, para uma colheita equivalente a 10,8 t/ha. Os valores de Kc, determinados para os dados de ETo do modelo de Penman-Monteith F AO, foram de 0,6; 0,5; 1,2; e 0,9, respectivamente para as fases de desenvolvimento vegetativo I, desenvolvimento vegetativo II, floração e desenvolvimento dos frutos e colheita. Para os dados de ETo calculados pelo tanque classe A, os valores de Kc foram de 0,6; 0,6; 1,0; e 0,9, para as mesmas fases descritas anteriormente.

Download or read book Sugarcane Bioethanol written by Luís Augusto Barbosa Cortez and published by . This book was released on 2010 with total page 994 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Food and Urbanism written by Susan Parham and published by Bloomsbury Publishing. This book was released on 2015-02-26 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities are home to over fifty percent of the world's population, a figure which is expected to increase enormously by 2050. Despite the growing demand on urban resources and infrastructure, food is still often overlooked as a key factor in planning and designing cities. Without incorporating food into the design process – how it is grown, transported, and bought, cooked, eaten and disposed of – it is impossible to create truly resilient and convivial urbanism. Moving from the table and home garden to the town, city, and suburbs, Food and Urbanism explores the connections between food and place in past and present design practices. The book also looks to future methods for extending the 'gastronomic' possibilities of urban space. Supported by examples from places across the world, including the UK, Norway, Germany, France, Spain, Portugal, Greece, Romania, Australia and the USA, the book offers insights into how the interplay of physical design and socio-spatial practices centred around food can help to maintain socially rich, productive and sustainable urban space. Susan Parham brings together the latest research from a number of disciplines – urban planning, food studies, sociology, geography, and design – with her own fieldwork on a range of foodscapes to highlight the fundamental role food has to play in shaping the urban future.

Available in PDF, EPUB and Kindle. Book excerpt: In 1992, at the United Nations Conference on Environment and Development in Rio de Janeiro, the nations of the world agreed to implement an ambitious plan for ecologically sustainable human development. This book is a comprehensive review of U.S. efforts to achieve such development since Rio. The U.S. has unquestionably begun to take steps toward sustainable development. Yet the nation is now far from being a sustainable society, and in many respects is farther away than it was in 1992. Nevertheless, legal and policy tools are available to put the U.S. on a direct path to sustainability. This book brings together 42 distinguished experts from a variety of backgrounds and academic disciplines. It is among the most thorough assessments ever conducted of U.S. law and policy concerning the environment.
