A colheita de cana-de-açúcar, desde os tempos do Brasil Colônia, sempre foi uma tarefa dispendiosa em trabalho físico e recursos financeiros. A substituição da força humana por máquinas envolveu longos períodos de desenvolvimento, experimentação e investimentos, porque o processo de colheita envolve a execução simultânea de três tarefas distintas: I) corte e despalhe dos colmos, II) carregamento dos colmos nos meios de transporte e III) transporte dos colmos de cana até o pátio da unidade industrial. Cada tarefa com suas peculiaridades e exigências específicas, bem como a necessária aptidão para operação sincronizada nos talhões canavieiros, resultou em dois sistemas de colheita: a) Sistema CCT (corte – carregamento – transporte) ou semimecanizado; b) Sistema CTT (corte – transbordo – transporte) ou mecanizado. Ao longo do desenvolvimento desses sistemas de colheita de cana-de-açúcar, passando da colheita semimecanizada tipificada pela colheita manual com carregamento e transporte mecanizado para a colheita plenamente mecanizada, ocorreram dois eventos que marcaram profundamente a colheita canavieira no Brasil. O primeiro foi a mudança do transporte ferroviário pelo rodoviário, quando caminhões de diversas capacidades e tipos de rodados invadiram os canaviais, gerando problemas de compactação do solo, porém reduzindo o desmatamento causado pela busca de lenha, combustível para as locomotivas do transporte ferroviário. O segundo evento ocorreu mais recentemente, quando foi estabelecido um protocolo entre produtores e órgãos governamentais proibindo o uso do fogo para despalhe de pré-colheita dos canaviais. Essa proibição tornou praticamente inviável, economicamente, a colheita semimecanizada, que era, então, praticada pela maioria dos pequenos e médios produtores de cana-de-açúcar. Atualmente, sob os efeitos da busca por fontes alternativas de energia, passaram a incidir sobre a colheita mecanizada os efeitos da diferença entre "cana-sacarose" & "cana-energia". Essa diferenciação resultou em enorme alteração na tendência evolutiva dos projetos das colhedoras de cana-de-açúcar e na forma de recepção dessa matéria-prima nas unidades industriais. Nesta obra o autor faz uma análise dessas variáveis e dos requisitos de modelagem, visando avaliar o desempenho operacional e econômico de sistemas mecanizados de colheita de cana-de-açúcar de alta performance.

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.

How will global warming affect developing countries, which rely heavily on agriculture as a source of economic growth? William Cline asserts that developing countries have more at risk, such as their production capacity, than industrial countries as global warming worsens. Using general circulation models, Cline boldly examines 2071–99 to forecast the effects of global warming and its economic impact into the next decade. This detailed study outlines existing studies on climate change; Cline finds the Stern Report for the UK government's estimates most reliable; estimates projected changes in temperature, precipitation, and agricultural capacity; and concludes with policy recommendations. Cline finds that agricultural production in developing countries may fall an average of 16 percent, and if global warming progresses at its current rate, India's agricultural capacity could fall as much as 40 percent. Thus, policymakers should address this phenomenon now before the world's developing countries are adversely and irreversibly affected.

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.
