Resumo
O objetivo geral desta pesquisa é analisar a relação entre a gestão dos recursos hídricos, praticada em duas fecularias de mandioca do Escritório de Desenvolvimento Rural de Assis, e a Pegada Hídrica do produto final. Portanto, neste estudo multicasos, foi mensurada a Pegada Hídrica da mandioca, do processamento da mandioca para a produção de fécula e da fécula, e comparadas, por meio do coeficiente de correlação por postos de Spearman, as práticas de gerenciamento da água consideradas ideais em cada uma das fecularias estudadas. Ademais, foram identificadas as práticas efetivamente empreendidas. A coleta de dados ocorreu por meio da aplicação de formulários semiestruturados e entrevistas. Como resultado, na Fecularia A, o total da Pegada Hídrica do produto final foi de 2.607,25 m³.ton-1 de fécula e na Fecularia B de 1.764,13 m³.ton-1 de fécula, enquanto as práticas consideradas ideais, segundo o Coeficiente de Spearman de 0,5857, possuem correlação positiva de moderada a forte. Igualmente, as práticas efetivamente realizadas são semelhantes e sugerem exercer influência sobre o resultado da Pegada Hídrica. Este trabalho possibilitou o conhecimento do consumo hídrico na produção da fécula de mandioca, de forma a evidenciar fatores, de ordem interna e externa às fecularias, influentes na apropriação do recurso hídrico nas mesmas.
The general objective of this research is to analyze the relationship between the management of water resources, practiced in two cassava starch of the Office of Rural Development of Assis, and the Water Footprint of the final product. Therefore, in this multi-level study, was measured the Water Footprint of cassava, cassava processing for starch production, and starch, and were compared, by means of the Spearman's Rank Correlation Coefficient, water management practices considered ideal in each of the farms studied. In addition, the practices actually undertaken were identified. Data collection took place through the application of semi-structured forms and interviews. As a result, in Cassava Starch A, the total Water Footprint of the final product was 2,607.25 m³.ton-1 starch and in Cassava Starch B, 1,764.13 m³.ton-1 starch, while the practices considered ideal, according to the Spearman Coefficient of 0.5857, have a moderate to strong positive correlation. Equally, the practices actually carried out are similar and suggest influence on the result of the Water Footprint. This work made possible the knowledge of water consumption in the production of cassava starch, in order to show factors, internal and external to the cassava starch, influential in the appropriation of water resources in them.
