O Processo de estrangeirização da Terra no Brasil: estudo de caso da empresa Umoe Bioenergy no município de Sandovalina (SP)

From the agri-food crisis of 2007/2008, we live an intensifying period in the global land rush. The land grabbing is analyzed as a process that occurs on a global scale, especially to countries in Africa and Latin America, the main targets of the current global competition for land, because beyond the earth have low prices and the legislation be flexible, low and ineffective supervision of the state (especially in the issue of environmental and labor laws), also have vast tracts of arable land, with fertile soils and high availability of water resources (the latter element has become relevant in that case analysis). In addressing the land foreignization in the XXI century it is necessary to speak about the issue of biofuels and bioenergy, since it is these that define the current phase of land foreignization in Brazil. In the 1970s occurred the first incentive to produce ethanol in the sugarcane cultivation, with the policy of the National Alcohol Program (PROALCOOL). From the 2000s this interest again sharpened up and foreign capital began to see in Brazil a great opportunity for a production facility and purchase of old agro-processing plants that were implanted in PROALCOOL period but who were disabled. This is the case of Umoe Bioenergy, Norwegian company that in 2006 started its production in the municipalities of Narandiba and Sandhurst, located in the Pontal do Paranapanema region that, in turn, is the region of São Paulo with larger agrarian conflicts, settlements land reform, land grabbing and high poverty rates...

Os financiamentos do BNDES às usinas sucroalcooleiras paulistas: potencialidades da ampliação da desigualdade regional no Brasil

The present work focuses on addressing the financing made by BNDES to sucroalcooleiras plants located in the State of São Paulo in Brazil. The study points out the Bank loans at São Paulo due to accumulation of plants technical objects that BNDES loans provide the State, with the installation of new equipment, machinery and services in canavieiros enterprises for electric power generation. Sucroalcooleiras plants are getting financing from BNDES to expand and diversify power generation in the country, mainly in São Paulo, because residential and industrial consumption of electricity grows annually. The offer of new financing to sucroalcooleiras plants for energy production Sao Paulo electric provides continued technical density in São Paulo and the expansion of regional inequality in the country. Therefore, the present study highlights for the period 2008 to 2013 the BNDES financing for are sucroalcooleiras plants in order to highlight the consolidation of technical objects in the State and show that the funding will help in the expansion of regional disparity

Análise estatística de parâmetros elétricos em usinas sucroalcoleiras do centro-oeste paulista

The industry of sugar cane has become an important contributor to the generation of electricity in Brazil. Currently there are 434 sugar and ethanol plants operating in the country, 23% of the total export electricity to the National Integrated System (SIN), the state of São Paulo has 182 plants and 30% of them export energy to the SIN. The objective of this study is to compare parameters of electrical efficiency in the sugar and alcohol industry. For the study, three plants localized in the midwest region of Sao Paulo state with great potential for production and exporting bioenergy were chosen. Five energy analyzers LANDYS + GYR SAGA were used for measure the electrical parameters. The variables studied were energy consumption (C) and power factor (PF). For the statistical analysis it was adopteda randomized block design in a factorial 3 5composed of three companies and five sectors of energy consumption,in which: reception(1), milling (2), boiler (3), supporting activities / juice treatment (4), and distillation (5), totaling 15 treatments. Each group comprised 192 repetitions (48 hours 4 measurements per hour). It was concluded that there is no interest for the plans to fix the FP and reach a value 0.92, which is considered the ideal power factor.This,because the plants generate their own energy and are not penalized. Regarding the energy consumed, all sectors had significant differences. When comparingsector to sector, the plant called USB showed no significant differences in sectors 1 and 3, and the plant USC, in sectors 1 and 4. Considering the production units of this sector and selling power this type of evaluation is essential to perform this analysis, since the analyzed sectors are most important in the production of sugar and ethanol, and analyze and monitor these parameters, use and consumption energy can provide a greater supply of energy to be commercialized.

Simulação da produtividade de cana-de-açúcar (Saccharum officinarum L.) na região nordeste do Brasil, utilizando o modelo DSSAT

The objective of this study was to simulate the potential stem and sugar yield of sugar cane (Saccharum officinarum L.) in the Northeastern Brazil (Petrolina-PE and Teresina-PI) and analyze 4 varieties in different planting seasons in two environments: irrigated and rainfed cultivars. The model of simulation was DSSAT/CANEGRO (Decision Support System for Agrotechnology Transfer) and the four sugar cane varieties were as follows: RB86 7515, CTC 4, CTC 7 and CTC 20 (all in 1.5 year cycle). Analysis of variance was performed on the results and means were compared using the Tukey test with probability level at 5%. March is the recommended month for planting in Teresina, PI. In Petrolina, PE, rainfed planting is not advisable because of the extended water deficit all year long. In an irrigated environment, no difference was found concerning stem yield as a function of planting season, for all varieties in the study regions. The stem and sugar yields were always higher in irrigated environment as compared with those in rainfed environment in all municipalities and study varieties. The simulation model provided good estimate of stem and sugar yields as compared with experimental data in Teresina, PI.
