Brazil is an important sugar cane producer, which is the main resource for ethanol production, a renewable source of energy. This agricultural commodity is important to the country economy, becoming fundamental to improve models that assist the crops monitoring process. Vegetation indexes originated from remote sensing images and agrometeorological indexes can be combined to represent sugar cane fields...
Oil is currently the target of criticism and concerns on the issues of greenhouse gases emissions, escalating prices and decreasing availability. Brazil, since 1975, has been encouraging ethanol use as a bio alternative, either as a substitute or as an additive to gasoline. The launching, in 2003, of vehicles that can run on any proportion of ethanol and gasoline, reinforced this process. These flex...
Flex fuel vehicles can be powered by any mix whatsoever of gasoline and ethanol. Special software for fuel identification and motor control is its main feature. Beginning in 2003, today already 23% of the Brazilian fleet and 95% of new cars have been built using this technology. Bosch was the pioneer in an early version in USA, in which it has been investing since the 80s. Bosch also made the earliest...
Time series of remote sensing EVI/MODIS data are an important source of information to evaluate the direct land conversion to sugarcane in response to increased ethanol production in Brazil. The present work uses a time series of EVI/MODIS data to identify the land use prior to the conversion to sugarcane in a dense cultivated region in Parana?? State, Brazil. Some sugarcane fields were selected over...
Pro-Alcool the National Alcohol Program began in 1975 and was a government financed program, developed on account of the petrol crisis of 1973, and fortified due to the second impact of 1979. This program aimed to substitute gasoline with ethanol from sugar cane on a grand scale, thereby reducing the dependence on imported petroleum. During the decades to follow, as the international price of petrol...
This paper uses the functions of technological systems of innovation to compare the evolution of bioethanol for the transportation sector between the U.S. and Brazil. It argues that differences in how functions of innovation operate within each system can explain different performances of bioethanol development over time. Despite the economic crisis of the 1980s, Brazil's strong strategic guidance...
