| Resumo: | The Drought Polygon is a territory that characterizes the area of predominance of semiarid conditions in the Northeast region. In Rio Grande do Norte, the Drought Polygon covers more than 90% of the municipalities, which have a diversified water structure, with specific potentialities and fragilities. This high coverage of the Drought Polygon in the state has resulted in distinct levels of vulnerability to water collapse. Based on this context, the aim is to analyze the Drought Polygon and the vulnerability to water collapse in the territory of Rio Grande do Norte, from 2015 to 2017. To achieve this objective, a set of methodological procedures, of a theoretical and empirical nature, such as the construction of a theoretical and conceptual contribution on elements of water structure, potentiality and fragility, vulnerability to water collapse, and Polygon of Droughts. In addition, cartography was produced to characterize water resources; the calculation of vulnerability to water collapse was carried out; and later, the information of water collapse and those of Polygon of Droughts were superimposed cartographically. It was verified that the relationship between the Polygon of Droughts and vulnerability to water collapse in Rio Grande do Norte, between 2015 and 2017, generated four specific territorial cuts: 1) municipalities that are not part of the Drought Polygon and that present medium vulnerability to collapse water; 2) municipalities that are part of the Drought Polygon and that present medium vulnerability to water collapse; 3) municipalities that are not part of the Drought Polygon and that present high vulnerability to water collapse; and 4) municipalities that are part of the Drought Polygon and that present high vulnerability to water collapse. These cuts evidenced that the discussion about Drought Polygon and vulnerability to water collapse demanded different territorial analyzes, mainly for the planning and management of water resources in Rio Grande do Norte. |
