{"doi":"10.3390/w11061140","title":"Reassessing Water Allocation Strategies and Conjunctive Use to Reduce Water Scarcity and Scarcity Costs for Irrigated Agriculture in Southern Brazil","abstract":"<jats:p>The lack of adequate management programs alongside water resources overexploitation have led to undesirable effects such as water shortages and economic losses in several regions. Optimized water allocation strategies using groundwater and surface water resources could reduce water scarcity and scarcity costs by exploring the advantages and peculiarities of each source, thus reducing the effect of variability and uncertainties on water availability. The aim of this study is to assess economic water allocation and the potential of conjunctive use of surface water and groundwater operations using a hydro-economic model to evaluate scarcity and scarcity cost at an irrigated agricultural region in Southern Brazil. Results indicated the possibility to reduce but not entirely eliminate, water scarcity and scarcity cost based solely on the reallocation of water among users and crops, without generating water deficit to users downstream. Results also pointed to the elevated potential of groundwater use as a component to reduce scarcity and its costs, mainly through economic optimized strategies integrated with surface water.</jats:p>","journal":"Water","year":2019,"id":34690,"datarank":0.5173170427488695,"base_score":2.302585092994046,"endowment":2.302585092994046,"self_citation_contribution":0.3453877639491069,"citation_network_contribution":0.17192927879976255,"self_endowment_contribution":0.3453877639491069,"citer_contribution":0.17192927879976255,"corpus_percentile":null,"corpus_rank":null,"citation_count":9,"citer_count":7,"citers_with_citation_signal":5,"citers_with_endowment":5,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":179274,"name":"Guilherme Fernandes Marques","orcid":null,"position":1,"is_corresponding":false},{"id":179276,"name":"Josué Medellín-Azuara","orcid":"0000-0003-1379-2257","position":2,"is_corresponding":false},{"id":179273,"name":"Camila Dalla Porta Mattiuzi","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":2.302585092994046,"endowment":2.302585092994046,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24523987","pmcid":null,"openalex_id":"https://openalex.org/W2947255022","authors":[],"funders":[{"funder_name":"Coordenação de Aperfeiçoamento de Pessoal de Nível Superior","grant_id":"88881.064986/2014-0","title":null}],"total_grants":1,"fwci":0.6596,"citation_percentile":0.70100621,"influential_citations":1,"citation_trend":[{"year":2020,"count":1},{"year":2022,"count":2},{"year":2023,"count":3},{"year":2024,"count":1},{"year":2025,"count":2}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://www.mdpi.com/2073-4441/11/6/1140/pdf?version=1559543556","host_type":"journal"},{"url":"https://www.mdpi.com/2073-4441/11/6/1140/pdf?version=1559543556","host_type":"GOLD"},{"url":"https://www.mdpi.com/2073-4441/11/6/1140/pdf?version=1559543556","host_type":"publisher"},{"url":"https://www.mdpi.com/2073-4441/11/6/1140/pdf","host_type":"publisher"},{"url":"https://doi.org/10.3390/w11061140","host_type":"journal"},{"url":"http://americanae.aecid.es/americanae/es/registros/registro.do?tipoRegistro=MTD&idBib=2060951","host_type":"repository"},{"url":"http://americanae.aecid.es/americanae/es/registros/registro.do?tipoRegistro=MTD&idBib=2309802","host_type":"repository"},{"url":"http://americanae.aecid.es/americanae/es/registros/registro.do?tipoRegistro=MTD&idBib=2647082","host_type":"repository"},{"url":"https://doaj.org/article/27cbe016bb71449a9d442b287f55d821","host_type":"repository"},{"url":"http://dx.doi.org/10.3390/w11061140","host_type":"repository"},{"url":"http://rigeo.cprm.gov.br/jspui/handle/doc/21440","host_type":"repository"},{"url":"https://rigeo.cprm.gov.br/handle/doc/21463","host_type":"repository"},{"url":"http://hdl.handle.net/10183/198787","host_type":"repository"}],"fields_of_study":["Water resources management and optimization","Water-Energy-Food Nexus Studies","Irrigation Practices and Water Management","Environmental Science","Agricultural and Food Sciences"],"mesh_terms":[],"keywords":["Water scarcity","Scarcity","Overexploitation","Water resource management","Agriculture","Groundwater","Water resources","Environmental science","Farm water","Water use","Conjunctive use","Natural resource economics","Business","Water conservation","Economics","Aquifer","Geography","Ecology","Engineering"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Clean water and sanitation"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-09T19:35:47.043697Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
