The sugarcane industry has been important in the Brazilian economy since the colonial period. The search for alternative energy sources has gained more prominence, by offering a product generating clean energy. With the opening of the Brazilian economy, the sector has undergone transformations operating in a free market environment requiring greater efficiency and competitiveness of those involved in order to stay in business. This scenario is producer/supplier independent, and social aspects related to their stay in the market. Although its share in sugarcane production is smaller than the plant itself, it is still considerable having reached around 20% to 25% in 2008 by employing labor, also production factors had an important economic impact in the regions where they operate. Therefore, this study aimed to estimate the economic efficiency and production of independent sugarcane producers in the state of Paraná through the DEA model. The Data envelopment analysis (DEA) is a nonparametric technique that, using linear programming constructs production borders from production units that employ similar technological processes to transform inputs into outputs.The results showed that of the total surveyed, 13.56% had maximum efficiency (an efficiency score equal to 1). The average efficiency under variable returns to scale (BCC-DEA) was 0.71024. One can thus conclude that for the majority of the samples collected, it might be better use of available resources to the in order to obtain the economic efficiency of the production process.

This study was to evaluate the profitability of land use for production of sugar cane in the São Paulo North Region, under risk conditions, from two views: the owner operator and the cash rental operator. The owner operators have higher levels of profitability comparing to cash rental owners, but with higher levels of risk. The land owners aversive to risk fits better to rent system, since the minimum return is greater than the profitability of owners operators. Moreover, if the producer is willing to production risk, the income may reach approximately 3 times that one obtained by the tenants.

La producción de azúcar ha jugado un papel central en gran parte de la historia de Cuba, así como en Brasil. En algunos períodos de la historia de estos dos países se consideró esta actividad, tecnológicamente hablando, moderna, y en otros se mostraron retrasos y demoras.Durante el período que cubrimos, 1875-1929, el cultivo de caña de azúcar de Cuba fue el más desarrollado del mundo, presentando altos niveles de productividad. Ya la de Brasil estaba estancada en el tiempo, totalmente incapaz de competir en el mercado internacional.En Brasil, el estado de Sao Paulo se perfilaba como un productor emergente, dotado de una mayor capacidad de asimilación de la tecnología y la expansión del cultivo de caña de azúcar. En el proceso de despliegue de sus modernas plantas en primer lugar, el ejemplo de Cuba fue de grande influencia a los productores de Sao Paulo.Lo que pretendemos analizar con esta investigación es cómo el sistema cubano de transporte de la caña tuvo divulgación y fue asimilado parcialmente en el estado de Sao Paulo, que pronto se convertiría en el principal productor de azúcar en el Brasil.
