Recognizing that the rich knowledge held by Indigenous Peoples and local communities (IPLCs) regarding coastal-marine ecosystems is often overlooked in Marine Spatial Planning (MSP), the MSPglobal initiative of the Intergovernmental Oceanographic Commission (IOC), together with the Local and Indigenous Knowledge Systems (LINKS) programme of UNESCO, co-organized four international dialogues aimed at discussing challenges and good practices related to fostering the engagement of IPLCs and embracing Indigenous and local knowledge (ILK) in MSP processes. These four rounds of participatory meetings entitled “MSPglobal 2.0 Dialogues on Engaging Indigenous Peoples and Local Communities in Marine Spatial Planning” were held during the months of November and December of 2023 and involved 25 participants divided into two groups: Group 1 comprised mainly experts from Asia and the Pacific regions, and Group 2 comprised mainly experts from Africa and the Americas. The participants of the dialogues comprised representatives of research groups, MSP practitioners, governmental authorities, and a mix of Indigenous groups with experience in ocean management.This publication is a result of these dialogues and aims to support MSPglobal practitioners in engaging IPLCs and including ILK in MSP approaches. It also encourages co-management practices between governments and IPLCs at the local level and advocates for the development of MSP initiatives led by rights-holders, especially in areas where marine planning takes place within ancestral territories.This publication is divided into five parts. In Part 1, the purpose of this document, the procedures carried out to develop the participatory meetings and produce their outcomes, and the key concepts adopted are introduced. In Part 2, the challenges that may be encountered while including customary management systems in marine policies are presented. These challenges are grouped into seven interconnected topics. In Part 3, good practices for more inclusive and equitable marine spatial planning approaches are described. These are organized under overarching recommendations as well as specific recommendations for each phase of the MSP process. Cases studies illustrating real-world good practices provided by participants of the meetings are presented in Part 4. Finally, Part 5 of this publication addresses strategies for disseminating and implementing the outlined Good Practices.In parallel with this “Good Practices” publication (volume 2), MSPglobal also developed another publication (volume 1) aimed at describing Basic Concepts regarding the equitable and inclusive engagement of IPLCs and the consideration of ILK in MSP processes. This associated publication was prepared through a literature review of international guidelines, codes of conduct, academic papers, websites and real-world case studies addressing this topic. Therefore, it is highly recommended to read these Good Practices alongside the publication “Engaging Indigenous Peoples and Local Communities, and Embracing Indigenous and Local Knowledge in Marine Spatial Planning: Volume 1 – Basic Concepts” to gain a comprehensive understanding of the conceptual background behind the recommendations provided herein.
