Este livro recupera a trajetória de um dos mais importantes centros de pesquisa e formação de profissionais do setor agronômico brasileiro: a Escola Superior de Agricultura Luiz de Queiroz. Por meio de uma vasta pesquisa histórica, a autora recupera transformações políticas e econômicas ocorridas na virada do século XIX e que provocaram mudanças em todo o sistema de produção econômico e também no equilíbrio político brasileiro. As inovações exigiram mudanças e uma das respostas da elite e do governo paulista foi a criação da Esalq. Analisando a criação da Escola, Marly Therezinha Germano Perecin revela ainda os debates que definiram os rumos pedagógicos da Esalq nos primeiros anos e ajudaram-na a transformar-se no centro de excelência que é.

This manual describes, in detail, all the uses for geotextiles and geomembranes (synthethic polymers) in civil engineering: erosion control systems, embankments, pollution control systems, water storage, drainage, and road construction. Focuses on the application of geotextiles in bank and bed protection, construction and drainage. Also deals with production technology, properties and testing of geotextiles, and the designing of the geotextile-element in a structure. Aspects of execution and maintenance are also treated.

The design text, Sprinkle and Trickle Irrigation, opens up a new and clear window through which to view the physics, economics, design, and manage ment of pressurized irrigation systems. A broad array of system types and ap plications have been covered in detail to provide for complete understanding of systems design. Topics include soil-water-plant relations, general planning con cepts, hydraulics, economics, sizing, operation, maintenance, and special uses. Pressurized irrigation system types covered include hand-line, wheel-line, solid set, traveler, center-pivot, linear-moving and big-gun-sprinkler systems, pump ing systems, and a broad array of trickle system components. The work in this text culminates earlier major works by Jack Keller on the W. R. Ames Company Irrigation Handbook (1967), Rain Bird Sprinkler Man ufacturing Corp. 's Trickle Irrigation Design (1975), and the USDA-Soil Con servation Service's National Engineering Handbook, Section 15: Irrigation Chapter 11: Sprinkle Irrigation (1983) and Chapter 15: Trickle Irrigation (1984). These earlier works form the foundation upon which the majority of currently used design texts are based. The years of design and troubleshooting experiences of the authors and wide ranges of environments and design appli cations in which they have worked have resulted in the substance and robustness of this text in stated relationships and procedures.

Only once we understand the long history of human efforts to draw sustenance from the land can we grasp the nature of the crisis that faces humankind today, as hundreds of millions of people are faced with famine or flight from the land. From Neolithic times through the earliest civilizations of the ancient Near East, in savannahs, river valleys and the terraces created by the Incas in the Andean mountains, an increasing range of agricultural techniques have developed in response to very different conditions. These developments are recounted in this book, with detailed attention to the ways in which plants, animals, soil, climate, and society have interacted. Mazoyer and Roudart’s A History of World Agriculture is a path-breaking and panoramic work, beginning with the emergence of agriculture after thousands of years in which human societies had depended on hunting and gathering, showing how agricultural techniques developed in the different regions of the world, and how this extraordinary wealth of knowledge, tradition and natural variety is endangered today by global capitialism, as it forces the unequal agrarian heritages of the world to conform to the norms of profit. During the twentieth century, mechanization, motorization and specialization have brought to a halt the pattern of cultural and environmental responses that characterized the global history of agriculture until then. Today a small number of corporations have the capacity to impose the farming methods on the planet that they find most profitable. Mazoyer and Roudart propose an alternative global strategy that can safegaurd the economies of the poor countries, reinvigorate the global economy, and create a livable future for mankind.

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.
