Resumo:
Water charging and availability are instruments that are intrinsically related since scarcity would determine a possible economic value of water. The objective of this study is to demonstrate the water availability of the hydrographic basin of the Paraopeba River, raising the areas of greater and lesser availability and proposing the implementation of the water charging, considering scarcity as an index incorporated in its base. The methodology of this work was divided into three stages: the first, aimed at an analysis of the grant data and insignificant uses; the second analysis of water availability; and the third will be the proposal of charging with a scarcity index in its offer. As a result, this research shows that the insignificant user is capable of causing water unavailability and that with better knowledge of users (granted and insignificant) and water availability, it will show that the lack of efficient management is what is leading to water unavailability. In addition, the amount that could be collected if the basin had a water resource charge implemented will be presented, showing that the charge cannot be implemented for insignificant users even if they cause water unavailability.
