Coastal and marine spaces all around the world are committed to a current global sustainability agendas, in the seas and coasts, as well as their public policies and territorial governance agendas have received a special role in international discussions on the directions of development and conservation. In this context, the establishment of the Sustainable Development Agenda for 2030 (Agenda 2030) by the United Nations (UN) stands out which incorporated Objective 14, seeking to establish a science-political-society interface and strengthening the management of oceans and coastal zones for the benefit of humankind. In this scenario, in line with the global agendas and in order to identify and fill gaps in the interface between produced science and public policies for Brazilian marine-coastal environments, the initiative “Programa Horizonte Oceânico Brasileiro (HOB)” was created. The theme “Marine Space Planning (MSP)” is extremely relevant in the scope of the HOB, given its proposal for innovation through an ecosystem approach. Furthermore, MSP has been adopted as a mechanism for environmental policies in the international intergovernmental sector in countries with different levels of development, as a public policy and operational platform in planning and management of uses in the marine-coastal space. In this context, the activities of the Marine Space Planning Team (Team PEM) were established, which has been producing knowledge to strengthen the MSP in the path of collective inter-network learning and disseminating information that can assist future research, management and ordering actions in Brazilian seas and coasts, such as the publication of the.“I Volume Horizonte Oceânico Brasileiro” (Chapter 5 - Planejamento Espacial Marinho: Desafios e Oportunidades para Inserção Inter-Redes no Pré Planejamento Espacial Marinho Brasileiro) and the “Síntese para Tomadores de Decisão – I VOLUME HOB” (Planejamento Espacial Marinho: Desafios e Caminhos para sua Implementação) and the webinar of Marine Spatial Planning. This article aims to present the production of general knowledge about MSP by this group and its potential interaction with different systems (social, economic and political), looking to contribute and improving the information base of Brazilian coastal governance and also to subsidize possible initiatives related to the theme.
