Use of Geotechnologies in Mapping Grants in the Piancó/PB Hydrological Planning Unit in Years 2021 - 2024

Resumo

The grant is one of the instruments of the National Water Resources Policy-PNRH that emphasizes the regularization of the assignment regarding the use of water resources in the country. In this way, the main objective of this work is to analyze, under the temporal aspect, the granting of the right to use water resources in the Piancó Hydrological Planning Unit, located in the Piancó-Piranhas-Açu River Watershed, issued by the Paraíba, by through the Executive Agency for Water Management of Paraíba (AESA). In the methodological steps, the qualitative analysis was approached as the main method in an exploratory approach, as it sought, through the analysis of data and information, to explain the patterns of grants granted in the planning unit of Piancó/PB. In the period studied from 2021 to 2024, 256 grants were identified, with the predominance of the use of irrigation with 70% of the grants issued, as for the type of abstraction, there is a preference for underground abstraction with a percentage of 56%. As for uses, irrigation is well dispersed throughout the basin area, highlighting the importance of grants for rural supply. Therefore, there is a lack of standardization of grants, as well as the concentration of water use for irrigation activities.
