Many of these research projects use multiple case studies to extract lessons for wider contexts. The methods used by these studies, and the extent to which their results have validity beyond the individual case study, often remain unclear. This paper explores the challenges in performing cross-case analysis within what we denote as case-based globally focussed sustainability projects (CB-GSPs) and indicates solutions by combining information from semi-structured interviews with leading scientists from eight CB-GSPs. We identify six distinct challenges that are common across these studies with regard to generating action- able knowledge through cross-case analysis. Based on these findings, we propose a set of best practice recommendations for scientists, project partners, and funders to co-produce actionable knowledge for global projects on ocean conflict.

That is not easy for a coordinator. • If you want a global view, the number of partners increases, and budget limits come to bear more strongly. The framework needs to be devel- oped first and then targeted partners need to be invited to fulfil specified tasks. Planning at the beginning is key. • Need to check that those who are allocated tasks have the capacity to fulfil them; match the distribution of tasks to the distribution of fund- ing; ensure that the project coordinator has a scientific vision for the project. This is not necessarily given when a private company coordi- nates. • Time and capacity are needed • For big projects: (1) think of additional clustering into case types to introduce extra options for comparison (e.g., between cases in the global North; it is easier to learn from similar cases, different dimensions of comparison of case studies; (2) longer projects, more funding for empirical work and ambitious project management are needed; now case selection is driven by countries` eligibility for funding; funding for external collaborators is needed (researchers and others); need to be able to collaborate on a more equal basis with community collabora- tors (e.g., small scale fishers); (3) better to identify case types first and then collaborators; mediation via an organization might be good but that limits free competition for projects; a boundary organization that helps to pre-organize case studies might work; (4) if transdisciplinary research is the aim, funding for non-academic partners is needed; do not fund projects that have no ambition/experience in working with local people. Different core ambitions/sets of research; natural science cross-case comparisons seem easier than studies that contain social complexities. • A set of core methods needs to be combined with flexibility to complement and adapt them to context. • Simultaneous start of funding for all case studies/research teams and one set of reporting requirements within one project timeline is needed (rather than each national funder following their separate, and at times mutually inconsistent procedures); this is important for a global multi- case project to generate synergies through cross-case team collaboration • Project design: When working with indigenous communities, project design is challenging because trust and co-creation are key but not all “tools” fit with all cultures. This needs to be discussed early, during project framing; we need longer projects to allow for early redesign and starting problems (5 rather than 4 years). • Funding: The time frame including start and end dates for all funding agencies should be coordinated, and the degree of support should match the (planning and reporting) effort required from project scientists. The central funding (by a single partner country or by a central one-stop agency) would help project cohesion and dynamics. • Organization: Project teams that have experience with collaborative work, and are trusted locally are likely to be more successful. Frequent meetings (at least monthly) of all participants and in-person kick-off meetings are important; distributed leadership is good (e.g., co-chairs, topic leads, national coordinators…); where time zones and distance make interaction hard, a post- COVID communication strategy needs to be designed (e.g. go beyond emails and phone calls with Miro board, interactive tools, shared documents, online meetings). 13 Maritime Studies (2023) 22:48 Page 21 of 23 48 Acknowledgements The first ideas for this paper were drafted by Benasso, Sebastiano, Dejana Bouillet, Tiago Neves, and Marcelo Par- MG (who is a member of and coordinator of two case studies in the reira do Amaral. 2022.
