Resumo: The water exported indirectly by sending products to other countries, or vice versa, is called a virtual water flow and this can be measured through water footprint (WF) calculations, which represent the embedded water needed to manufacture a product. This present study aims to analyze the virtual water flow and the WF of the main products exported by municipalities in the state of Ceará in the year 2019, in order to enhance the management of the state’s water resources. Analytical hierarchy process (AHP), the most commonly used multicriteria decision-making method in the world, was used to determine which product is more sustainably produced by the municipalities of Ceará, with the criteria: WF, price, and volume exported. The alternatives are at least two of the seven categories of products exported by the state where the “fruit or vegetable juices” class was preferred as the most sustainable. It was found that most cities in the state that export agricultural products use only one basin, which can lead to very low reservoir levels, while the other hydrographic basins in the state are underused. It is worth noting that the Metropolitan Basin concentrates on 11 out of 32 municipalities that export abroad and that it is responsible for supplying more than 4,074,730 inhabitants, according to Brazilian Institute of Geography and Statistics (IBGE, 2019).

O presente estudo teve o objetivo de analisar o fluxo de água virtual e a pegada hídrica dos principais produtos exportados por municípios do estado do Ceará no ano de 2019, a fim de potencializar o gerenciamento dos recursos hídricos do estado. Utilizouse o analytical hierarchy process (AHP), método de tomada de decisão multicritério mais usado no mundo, aqui escolhido para determinar qual o produto mais sustentável produzido pelos municípios do Ceará, com os critérios: pegada hídrica, preço e volume exportado. As alternativas são pelo menos duas das sete categorias de produtos exportados pelo estado, e a classe de “sucos de frutas ou vegetais” foi preferida como a mais sustentável. Constatou-se que a maioria das cidades do estado que exportam produtos de origem agropecuária faz uso de apenas uma bacia, o que pode acarretar níveis muito baixos de reservatório, enquanto as outras bacias hidrográficas do estado são subusadas. Vale a pena salientar que a Bacia Metropolitana concentra 11 de 32 municípios que exportam para o exterior e é responsável pelo abastecimento de mais de 4.074.730 habitantes, segundo o Instituto Brasileiro de Geografia e Estatística (2019).Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)2021-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/xmlhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/100310.5327/Z217694781003Revista Brasileira de Ciências Ambientais (RBCIAMB); v. 56 n. 4 (2021): RBCIAMB - ISSN 2176-9478 - Dezembro; 608-620Revista Brasileira de Ciências Ambientais (RBCIAMB); Vol. 56 No. 4 (2021): RBCIAMB - ISSN 2176-9478 - December; 608-6202176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESenghttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1003/693https://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1003/709Copyright (c) 2021 Brazilian Journal of Environmental Sciences (Online)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLeite, Ivana SampaioSabiá, Rodolfo JoséMatos, Andrezza PereiraSilva, Camila Cavalcante2023-11-09T17:39:38Zoai:ojs.www.rbciamb.com.br:article/1003Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2023-11-09T17:39:38Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false
