“…Também pôde ser verificado que a formalização tem aumentado ao longo do tempo. Segundo Moraes (2007b), em 1992 a proporção dos empregados formais na cultura da cana-de-açúcar era de 53,6%. Esta tendência foi verificada para ambas as regiões produtoras: a região Norte-Nordeste em 1992 tinha 42,3% de empregados formais, em 2006 aumentou para 65%; na região Centro-Sul a proporção foi de 66% em 1992 para 83,2% em 2006.…”

The aim of this paper is to identify the determinants of the income of the employees of the sugarcane sector, and also for the sugar and ethanol industries. Special attention is given to union's role. Earnings equations were estimated for these sectors and information on union's action were collected in a field research. In the regressions estimated, the coefficients of the following variables were significant and had the expected signs: (i) gender (ii) region, (iii) education, (iv) threshold effect of education, (v) membership to labor unions. It was verified the existence and also the influence of labor unions on wage formation

Sustainable energy strategies require decision-makers in government, industry, academia and civil society alike to make choices among tradeoffs. Within the transport sector alone, ethanol has been shown to be the dominant solution among viable, low carbon options to date, yet questions remain over the economic and ecological impacts of this industry.In Brazil -the largest producer of sugarcane-based ethanol and a country with over three decades of ethanol development -we find a strong basis for evaluating the ethanol industry"s role in a national economy. In the mid 1970"s, Brazilian ethanol production received an important boost with the launch of the "Proálcool" program. The ethanol industry has subsequently evidenced flux until its consolidation in the period following 2000.Over the course of three decades, economic, institutional, technological and environmental determinants have factored in the success of Brazilian ethanol diffusion. In economic terms, price tradeoffs for ethanol vs. sugar and ethanol vs. gasoline played a role in scale-up of the biofuel together with balance of payment considerations. From an institutional standpoint, support for the Proálcool program, deregulation of the sugar-cane sector in the 1990"s and fuel pump adaptations also factored. With respect to technology, the development of flex fuel cars, greater use of mechanized harvesting, and launch of domestic, co-generated, electrical power were key drivers. Finally, in environmental terms, challenges associated with pollution and public health in major cities as well as questions related to climate change gained visibility.In this paper, we analyze a set of input-output tables for the Brazilian economy from 1975 to 2006, taking the above factors into consideration. Deriving a series of indicators, such as multipliers and linkages, we study the evolution of the ethanol sector"s role in the Brazilian economy and its relation to the productive structure of the country.

RESUMO:A prática agrícola da queima da palha da cana-de-açúcar tem por finalidade facilitar a colheita manual. No Estado de São Paulo, essa prática está submetida a uma rigorosa legislação ambiental devido ao impacto negativo para o meio ambiente. Está previsto que a queima da cana deve ser gradativamente eliminada até 2017. O presente trabalho tem por objetivo avaliar a área de cana colhida com e sem queima em todo o Estado de São Paulo. Para tal, foram utilizadas as imagens disponíveis do sensor TM a bordo do satélite Landsat-5. As imagens foram adquiridas de abril a dezembro de 2006, que corresponde ao período de colheita da cana. Essas imagens foram analisadas por meio de técnicas de processamento digital e interpretação visual. A área de cana colhida sem queima foi avaliada em 1.085.730 ha e corresponde a 34,7% do total da área mecanizável colhida. Isso atende à legislação ambiental que, para o ano de 2006, previa que 30% da área de cana fosse colhida sem queima. A sequência temporal de imagens adquiridas entre abril e dezembro permite identificar as áreas de cana colhidas sem queima e, portanto, distingui-las das áreas de cana colhidas com queima. PALAVRAS-CHAVE:queima da cana, modelo linear de mistura espectral, cana crua. REMOTE SENSING IMAGES FOR MONITORING THE SUGARCANE HARVEST ABSTRACT:The agricultural practice of burning the sugarcane straw has the intention of facilitating the manual harvest. In São Paulo state this practice is subjected to a rigorous environmental legislation, due to the negative impact for the environment. It is anticipated that sugarcane burning should gradually be eliminated until 2017. The present work has the objective of evaluating the sugarcane area harvested with and without burning in the entire state of São Paulo. For that purpose, available images from TM sensor, on board of Landsat-5 satellite, were used. Images were acquired from April to December 2006, which corresponds to the sugarcane harvest period. These images were analyzed by using digital processing and visual interpretation techniques. The sugarcane area harvested without burning was estimated as 1,085,730 ha and corresponds to 34.7% of the total mechanized harvested area. This is according to the expectation of 30% established by the environmental legislation for the year of 2006. The temporal image sequence acquired between April and December allows us to identify the sugarcane areas harvested without burning and, therefore, distinguish them from the sugarcane areas harvested with burning.
