O objetivo geral dessa pesquisa foi identificar as histórias de vida e as condições de trabalho, relatadas e percebidas pelos trabalhadores rurais do município de Sertãozinho/SP. Como objetivos específicos buscamos: Verificar os fatores de risco relacionados ao trabalho no contexto estudado; Analisar a percepção dos trabalhadores acerca de sua saúde; Identificar as estratégias de defesa utilizadas pelos trabalhadores rurais.

Os dados de natureza quantitativa foram tabulados e analisados em formas de tabelas e quadros. Os dados qualitativos foram analisados tomando como referência a Teoria do Desgaste Mental no Trabalho da autora Seligmann-Silva (1994) a qual considera que as situações de trabalho são correlacionadas ao desgaste mental, que é concebido numa perspectiva dinâmica, levando em conta a dimensão subjetiva... / The rural work, special in the sugar cane agricultere, is conditioned of intenses loads of work, subjecting the workers a risks like: acccidents of work; exposition to agrotoxics; and, musculoskeletal diseases. The overall objective of this research was to identify the stories of living and working conditions, reported and perceived by rural workers in the city of Sertãozinho/SP. The specifics objectives were: Check the risk factors related to work in the context studied; Analyze the perceptions of workers about their health; Identify the defense strategies used by rural workers. The instruments used for data collection was: Bookmarks Registration of the Program of Health’s Community Agents, Family Health Strategy; individual semi-structured interviews; photographic records.

The age of workers ranged from 20 (twenty) and 60 (sixty) years. The data were analyzed quantitatively and qualitatively. The quantitative data were tabulated and analyzed in forms of tables and charts. Qualitative data were analyzed with reference to the Theory of Wear Mental in the Work, by the author Seligmann-Silva (1994), which considers the working conditions are correlated to the mental strain, which is conceived in a dynamic perspective, taking into account the subjective dimension and confrontations.

This study uses energy and greenhouse gas (GHG) balances to evaluate how the scale of sugarcane cultivation affects the performance of a sugarcane bioenergy system generating exportable electricity from bagasse. Small-, medium-, large- and miller-planter systems, with cane field areas of less than 10 ha, 10 – 42 ha, 42 – 2000 ha, more than 2000 ha respectively, were modelled. Each of them also has different combinations of manual and mechanical agricultural operations, resulting in different cane yields. Miller-planter system (fully mechanised) performs best with energy yield ratio of 10.99, GHG emissions in bagasse electricity of 0.0633 kg CO2eq/kWh and avoided life cycle GHG emissions of 82.07% when replacing electricity from coal, whereas small-planter system (fully manual) has the worst performance with energy yield ratio of 6.82, GHG emissions in bagasse electricity of 0.0881 kg CO2eq/kWh and avoided life cycle GHG emissions of 75.03% when substituting electricity from coal. Sensitivity analyses show that relative performances of all sugarcane planter systems both in terms of energy and GHG emissions are not significantly affected by variations in bagasse allocation factor, in sugarcane yield and in fertiliser input (the most energy-intensive and GHG-emitting component). Moreover, they confirm miller-planter system as the overall best performer and indicate that increasing small-planters’ cane yield is the critical measure to improve their energy analysis performance. In terms of the nature of agricultural operations, mechanical operations do not necessarily require more input energy than their manual counterparts, contrary to common belief. This is the case for fertilisation, irrigation and cane loading. Fully mechanised sugarcane production at miller-planter scale is therefore strongly encouraged.
