Influência das distintas dominialidades das águas no Brasil na gestão dos recursos hídricos - estudo de caso

Abstract

The dominance of water is considered a factor of complexity in the management of water resources in Brazil. Although Law No. 9.433/1997 affirms the implementation of integrated management, the country still has deficiencies in this area. The dominance in conjunction with the existing deficiency in the integration between the water resources management bodies of the different spheres can reflect on the behavior of the water users. State regulations on collection and granting are motivating agents for an eventual alternation between sources of abstraction, mainly due to the possibility of the existence or not of collection, as well as the fact that surface water presents a greater advance in the implementation of collection in relation to underground ones. Thus, this study aimed to evaluate the behavior of water resource users in Brazil in a hydrographic basin in the federal domain due to the criteria adopted for granting and charging in each federative unit - UF of the basin. To that end, a survey was made of the legislation relevant to water management in UFs, as well as surface and underground grants. From the identification of the most expressive users in each unit, ananalysis was carried out in order to observe the reflexes of dominance and management carried out in the basin on the user's behavior. It was found that dominance reflects the behavior of users of water resources so that, possibly, they migrate between sources of funding or reduce their demands in view of the implementation of the collection and seek sources that can offer higher amounts that can be granted.
