This study evaluated the spatial distribution of annual rainfall in a semiarid Brazilian basin under different regimes and its impact on land use and land cover dynamics. Climate Hazards Group InfraRed Precipitation with Stations (CHIRPS) records and observed data from 40 weather stations over a time series of 55 years were used, in addition to the Standardized Precipitation Index. Spatiotemporal analysis was carried out based on geostatistics. Remote sensing images were also interpreted for different rainfall regimes using the Normalized Difference Vegetation Index and Modified Normalized Difference Water Index. The Gaussian semivariogram model best represented the rainfall spatial structure, showing strong spatial dependence. Results indicated that rainfall amount in the basin significantly increases with elevation, as expected. There is high variation in the dynamics of water storage that can threaten water security in the region. Our findings point out that the application of geostatistics for mapping both the annual precipitation and the Standardized Precipitation Index provides a powerful framework to support hydrological analysis, as well as land use and land cover management in semiarid regions.<\/jats:p>","DOI":"10.3390\/rs15102550","type":"journal-article","created":{"date-parts":[[2023,5,12]],"date-time":"2023-05-12T10:49:51Z","timestamp":1683888591000},"page":"2550","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Spatiotemporal Analysis of Rainfall and Droughts in a Semiarid Basin of Brazil: Land Use and Land Cover Dynamics"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5283-2958","authenticated-orcid":false,"given":"Lizandra","family":"de Barros de Sousa","sequence":"first","affiliation":[{"name":"Department of Agriculture Engineering, Federal Rural University of Pernambuco, Rua Dom Manoel de Medeiros, Dois Irm\u00e3os, Recife 52171-900, PE, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abelardo Ant\u00f4nio","family":"de Assun\u00e7\u00e3o Montenegro","sequence":"additional","affiliation":[{"name":"Department of Agriculture Engineering, Federal Rural University of Pernambuco, Rua Dom Manoel de Medeiros, Dois Irm\u00e3os, Recife 52171-900, PE, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1318-2320","authenticated-orcid":false,"given":"Marcos Vin\u00edcius","family":"da Silva","sequence":"additional","affiliation":[{"name":"Department of Agriculture Engineering, Federal Rural University of Pernambuco, Rua Dom Manoel de Medeiros, Dois Irm\u00e3os, Recife 52171-900, PE, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2172-4732","authenticated-orcid":false,"given":"Thayn\u00e1 Alice Brito","family":"Almeida","sequence":"additional","affiliation":[{"name":"Department of Agriculture Engineering, Federal Rural University of Pernambuco, Rua Dom Manoel de Medeiros, Dois Irm\u00e3os, Recife 52171-900, PE, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ailton Alves","family":"de Carvalho","sequence":"additional","affiliation":[{"name":"National Institute of Semiarid, Avenida Francisco Lopes de Almeida, Serrot\u00e3o, Campina Grande 58434-700, PB, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8355-4935","authenticated-orcid":false,"given":"Thieres George Freire","family":"da Silva","sequence":"additional","affiliation":[{"name":"Department of Agriculture Engineering, Federal Rural University of Pernambuco, Rua Dom Manoel de Medeiros, Dois Irm\u00e3os, Recife 52171-900, PE, Brazil"},{"name":"Academic Unit of Serra Talhada, Federal Rural University of Pernambuco, Avenida Greg\u00f3rio Ferraz Nogueira, Serra Talhada 56909-535, PE, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0135-2249","authenticated-orcid":false,"given":"Jo\u00e3o Luis Mendes Pedroso","family":"de Lima","sequence":"additional","affiliation":[{"name":"MARE\u2014Marine and Environmental Sciences Centre, ARNET\u2014Aquatic Research Network, Department of Civil Engineering, Faculty of Science and Technology, University of Coimbra, Rua Lu\u00eds Reis Santos, P\u00f3lo II, 3030-788 Coimbra, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3859","DOI":"10.5194\/hess-21-3859-2017","article-title":"Spatial and temporal variability of rainfall and their effects on hydrological response in urban areas\u2014A review","volume":"21","author":"Cristiano","year":"2017","journal-title":"Hydrol.
