Brazilian Semi-arid Region
The Brazilian Semi-Arid Region is delimited by the Superintendence of Northeastern Development - SUDENE, considering the weather conditions that prevail in the semi-arid contexts, as the pluviometry. As a reflex of the weather conditions, the hydrography is frail, in various ways, being unable to support the larger rivers so that they can be perennial in the long drought periods, the exception being the São Francisco River. Due to its hydrologic characteristics, which allow for its subsistence throughout the year, the São Francisco River gains a special meaning to the populations living by the river and those of the Sertão area.
About the publication - 2022
The Brazilian Semiarid now comprises 1,477 municipalities, belonging to the states of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, Minas Gerais and Espírito Santo. Of this total, 1,212 municipalities were already included in the previous delimitation and were confirmed. Other 215 municipalities qualified, according to the new criteria adopted. It should be mentioned that 50 municipalities included in the previous delimitation would not integrate the Semiarid, as they did not hit any of the technical criteria established. However, these 50 municipalities were allowed to appeal for their exclusion from the Semiarid up to April 2023. As the current release corresponds to the status of the territorial division up to December 31, 2022, the IBGE decided to keep not only the municipalities included in the Semiarid according to the changes, but also those that might be excluded, as explained in the resolutions no. 155, of April 29, 2022, and no. 163, of December 15, 2022, of the SUDENE´s Advisory Board.
