RT journal article T1 Matinhos Beach Nourishment and the Complexity of Coastal Management: Cooperation between the University and the Prosecutor’s Office T2 Nutrición de la Playa de Matinhos y Complejidad de la Gestión Costera: Cooperación entre la Universidad y la Fiscalía A1 Silveira Miura, Aika A1 da Mata Cavalcante, Priscila A1 Lloret, Jaime K1 beach nourishment K1 environmental licensing K1 coastal management AB The Paraná State Prosecutor’s Office launched an investigation against the Paraná State and its EnvironmentalAgency due to serious illegalities in the bidding and li-censing procedure of a project that cost around US$77,861,223.28, to contract a company for the executionof the work of Matinhos Seafront Recovery. Since theanalysis of the project required deep technical and scientific knowledge, the Prosecutor’s Office had the support ofthe Federal University of Paraná (UFPR), which deliveredseveral technical notes, pointing out the problems of thestudies, the administrative procedures, and the projects.After a long attempt of trying to reach an extrajudicialagreement, the Prosecutor’s Office had no other optionthan to file a lawsuit against the Paraná State and the IAT(Water and Land Institute) to annul the Bidding Procedure No. 49/2021 and the environmental licensing protocols and permits, since the environmental licensing procedures are null, without the obligatory Environment ImpactAssessment (EIA/RIMA) and before the preparation of the basic and executive projects. Furthermore, the projects wereexpensive and carried out immense cultural, social, and environmental impacts and significant modifications to thenatural environment, its coastal dynamics, and the ecosystem services provided, losing natural habitats, and interferingwith nutrient circulation. Due to a partnership between the Public Ministry of Paraná and the Federal University ofParaná, a class action still pending final judgment was drawn up to analyze and question fundamental technical pointsneglected in carrying out public works to nourish the beach, in Matinhos, on the coast of the Paraná State, Brazil. Thestudy reviews technical notes presented by university researchers and highlights gaps in the project’s environmentallicensing. Remote sensing was used to analyze the variability of the area after beach fattening.
