The goal of this work consisted in the proposition and methodological development and of an Indicators System aimed at evaluating the potential for water sustainability for sugar cane culture expansion in the allowance for agricultural and territorial planning and water resources management. The Indicators System (IS) SISH-Cana was drawn from a methodological proposal of integrating different conceptual frameworks of reference for conceptual modeling of environmental management problem raised by the case of sugar cane culture expansion trends on areas of the Brazilian Cerrado, which at its greatest extent, presents seasonal water deficit, allowing the sugarcane cultivation only under supplemental irrigation. This methodology has been deliberately designed to meet the goals of this thesis. Through this was possible to elaborate the IS with a functional design and organizational structure in modules which earned the same satisfactory flexibility in terms of functionality and applicability. The system was designed for to meet strategic and tactical management levels and analytical assessments, diagnostic and prognostic, as well as descriptive summaries, through direct, relevant indicators, aggregated as dimensionless ratios. But, with physical meaning, derived from available public data or data extracted from the simple espacializados models, which was one of the premises of the proposal. To demonstrate the applicability of SISH-Cana were conducted two case studies. The first study case, strategic level-oriented management, consisted in the assessment of environmental favorability, sustainability and water potential in monitoring the process of expansion of sugarcane cultivation in the period between the years-the 20062007 agricultural, 20102011 occurring within the micro-regions: Sudoeste de Goiás; Vale do Rio dos Bois; Quirinópolis and Meia Ponte, belonging to, considered as relevant hotspots of sugarcane expansion in the State of Goiás. The second study had the same purpose, but focused on the evaluation of Rio Verde basin, located in the same region and federal State. The results demonstrate the potential of applicability and functionality of the system of indicators proposed to deal of environmental issues explained. It is concluded that the purposes and objectives have been achieved, validating the thesis, since it was possible to demonstrate the managerial and practical value of the Indicator System SISH-Cana . It is, thus, have contributed to the development of methodologies oriented for agriculture and water resources planning.
