Análise dos possíveis impactos das mudanças climáticas na segurança da navegação, sob o enfoque da autoridade marítima

Abstract

ABSTRACT THE POSSIBLE IMPACTS FROM CLIMATE CHANGE ON NAVIGATION SAFETY, UNDER THE FOCUS OF THE MARITIME AUTHORITY Climate change is already a reality on the planet and hydrometeorological extremes are being strongly affected by it, and projections for the future indicate that they will become increasingly intense. Within the maritime context, it is inevitable that climate change will directly influence navigation safety and the blue economy and, in Brazil, ensuring navigation safety is one of the responsibilities of the Maritime Authority. Given the evidence that the rise in sea level is irreversible in the coming centuries and the importance of navigation for Brazil, this research aims to identify in the Vessel Traffic Service, which aids maritime navigation, the necessary adaptations so that it can effectively contribute to mitigating its possible effects on maritime port accessibility, on the safety of navigation in Brazilian Jurisdictional Waters, in particular, the rise in the average sea level, predicted for the Brazilian coast. Experiences and good practices in several ports around the world demonstrate the applicability of mitigating measures and contribute to the dissemination of knowledge and awareness regarding possible impacts on port operations and infrastructure, through the standardization of procedures and training; financial investments in the installation of meteorological and oceanographic monitoring equipment; implementation of alert and alarm systems to prevent extreme hydrometeorological events; the inclusion of studies aimed at creating vulnerability maps and flood risk maps in the port area and the implementation of digital systems. The proposed actions can support the development of requirements for the renewal of the Service's operating authorization in Brazil in order to include measures to increase the operational resilience of this important service in the face of climate change.
