Conflicts over multiple uses of water in the reservoir of the Tucuruí Dam arise with the announcement of the construction of the mega dam in the region, and the subsequent social and environmental conflicts. Allied to the raising of the social perception level concerning environmental problems, the search for efficient process of water resources management also increases. This study aims to analyze and typify the conflicts over multiple uses of water in the reservoir of the Tucuruí Dam, using the software for qualitative modeling NVivo 8 as a decision support tool, and thus to determine the best alternatives to be adopted for the conciliation of multiple uses in the reservoir. The typifications performed were based on the analysis of conflicts, its components, elements and aspects, type, nature and origin. In such case, three main types of conflict were identified in the Tucuruí Dam reservoir: conflicts among different water users groups, conflicts over hydraulic works, and conflicts arising from environmental pollution. For this study, a qualitative approach was adopted, using the cognitive mapping method. This type of mapping enables the construction of a cognitive model for the management of conflicts in Tucuruí reservoir. Thus, the software NVivo 8 enabled, besides the analysis of data obtained in the interviews and literature review, the construction of the graphic model to support management of conflicts over multiple uses of water. It was verified that one of the solutions for conflicts is through its analysis in order to investigate the appropriate mechanisms to resolve them, and subsequent proposal of structural and/or non-structural measures for water resources management. The main actions for the solution of conflicts are defined in methods of long-term institutional resolution. The model may act as a support for planning and decision making, concerning environmental problems, the participation of water users in the water system, public policies, as well as integrated water resources management. Then, it follows that the exploitation of water resources should provide the multiple uses of water in response to the environmental sustainability principles, inserted in a process of management of conflicts over multiple uses of water and integrated water resources management.

Segurança de barragens e governança de risco em hidrelétricas na Amazônia

The construction and operation of hydroelectric power plants produce risks, including dam failure, and damage to downstream communities. These technological risks may be fraught with complexity, uncertainty, and ambiguities. In this context, dam safety management needs to be expanded in a risk governance process. This governance has as fundamental components the prediction of spaces of participation and social involvement, as well as risk communication. This case study presents the risk governance analysis in the dam’s safety regulation scenario, taking into account the Amazon region context, and the case of the Tucuruí hydroelectric power plant. The analytical stage of this research involved the use of French Discourse Analysis concepts to reveal discursiveness regarding the presence of participation channels, or the silencing of social involvement in dam safety management. To do this, data were selected from four main groups: technical documents (reports and manuals), legal-normative documents (legislation and normative resolution), scientific manuscripts, as well as semi-structured interviews. These interviews were carried out from the definition of three groups in the governance arena: the regulated one, the regulators and social groups affected by the risk. Thus, it was identified that in the case of the Tucuruí hydroelectric plant, there is no communication channels and spaces of social participation for the effective social involvement in risk governance. Therefore, there is a limitation of the social group contribution in the dam safety management, as well as weaknesses in the decision-making, in the risk governance. From the point of view of dam safety regulation, it is understood that effective channels of dialogue between dam developers, regulators and the community affected by the risk should be provided, guaranteeing the effective inclusiveness of risk governance.
