Incorporating Gender-Sensitive Data Enhances Insights in Marine Spatial Planning

In an era where sustainable management of marine environments is becoming increasingly critical, understanding the nuanced ways in which different demographic groups interact with ocean spaces has emerged as a frontier of vital importance. A groundbreaking study led by researchers at the University of California, Santa Barbara, underscores the importance of incorporating gender-sensitive analyses into marine spatial planning (MSP). Published recently in the journal Marine Policy, this research unveils significant gender-based differences in how men and women use and value marine spaces around the world, challenging long-standing assumptions that have often overlooked the complex social dimensions of ocean governance.

Marine spatial planning is a sophisticated framework that aims to allocate oceanic and coastal spaces effectively to balance environmental conservation, economic growth, and societal well-being. Traditionally, MSP efforts have been predominantly informed by aggregated data that rarely disaggregates users by gender or examines the spatial patterns of ocean use through a gendered lens. Abigail Vath Meyer, a geospatial developer with the Will McClintock Lab at UCSB’s National Center for Ecological Analysis and Synthesis (NCEAS), spearheaded this research which harnessed innovative geospatial tools to chart these patterns, revealing substantial disparities in how men and women interact with marine environments.

One of the core findings of the study is that women tend to use ocean spaces much closer to the shore compared to men, a spatial tendency that persists across diverse socio-economic contexts and geographic regions including the Maldives, the Azores, and Belize. This spatial proximity to shore extends beyond just direct commercial or artisanal fishing activities; it includes vital cultural and community functions, which are often informal and therefore inadequately captured in official data sets. Women’s engagement with marine environments often includes non-extractive activities and indirect economic roles such as gear preparation and catch processing, which are essential to the marine economy yet remain largely invisible in formal maritime governance.

The researchers employed the innovative marine spatial planning application SeaSketch, developed within the McClintock Lab, to gather high-resolution ocean use data directly from stakeholders in these three countries. This approach allowed the team to map and analyze spatial patterns of ocean use at a granular level, going beyond traditional top-down data collection methods. The precise geospatial data drew attention to the critical nearshore zones valued by women, highlighting their overlap with spaces designated for cultural significance and community safety, particularly for children and families.

This invisibility of women’s ocean uses in formal economic and governance frameworks bears significant consequences. Meyer emphasizes that overlooking nearshore and informal uses risks undervaluing a large segment of maritime stakeholders. Such a blind spot in MSP can lead to plans that fail to incorporate the full spectrum of ocean users, resulting in inequitable outcomes that disenfranchise key groups and undermine the social legitimacy and sustainability of marine governance initiatives. Recognizing and integrating gender-specific spatial data can thus enhance not only fairness but also the effectiveness of marine conservation and resource management.

The study also highlights notable cross-regional variations. For example, while men overwhelmingly dominate most marine economic sectors and are the primary data representatives in ocean use surveys, the researchers found compelling evidence that female recreational fishers in the Azores exhibit higher awareness and compliance with marine protected area (MPA) regulations than their male counterparts. This compliance is crucial for the success of MPAs, which serve to protect critical habitats and fish stocks. Such behavioral insights open avenues for tailored community engagement strategies that capitalize on women’s potential role as stewards of marine ecosystems.

In Belize, the research prompted a reassessment of ocean use data collection methodologies. Following the study, Belizean marine planners conducted a second round of surveys aimed explicitly at increasing female representation. This policy response reflects the practical value of gender-disaggregated data, indicating that incorporating such insights can lead to more inclusive and responsive marine spatial governance.

The researchers caution, however, that gender roles in ocean use are highly variable and intersect with other factors such as age, marital status, wealth, and nationality. This complexity underscores the need for nuanced and context-specific approaches in MSP, rather than one-size-fits-all models. Failure to account for these intersecting identities risks perpetuating exclusion and reducing the potential for marine spatial plans to deliver co-benefits in ecology, economy, and social equity.

The research thus offers a methodological leap forward by demonstrating how geospatial technologies, combined with participatory data collection, can illuminate the uneven ways men and women engage with marine environments. It also contributes to an emerging normative framework that calls for “gender mainstreaming” within MSP, aligning with international directives such as those articulated by the European Union. Yet, Meyer and McClintock note that despite such policy recommendations, practical applications remain sparse due to the lack of fine-scale, gender-disaggregated ocean use data.

Ultimately, this study makes a compelling case for why MSP must move beyond traditional economic and environmental metrics to incorporate social dimensions that have been historically marginalized. Collecting and analyzing gender-disaggregated data not only democratizes the planning process but also enriches the knowledge base, enabling planners to craft marine policies that are both equitable and ecologically sound. This approach also ensures that women’s less visible but nonetheless critical roles in the marine domain receive proper recognition and consideration in governance decisions.

The implications of this research extend globally, offering a replicable analytical framework for coastal nations everywhere, regardless of development status. As climate change, overfishing, and habitat loss intensify pressures on marine ecosystems, inclusive and data-driven MSP becomes ever more imperative. Insights into gendered spatial patterns equip policymakers with a powerful tool to align marine uses with conservation goals while fostering community support and resilience.

This pioneering research was facilitated through an international collaboration involving multiple institutions and experts, including co-lead author Marinez Scherer at the University of Santa Catarina in Brazil, and partners from The Nature Conservancy in Belize, the Waitt Institute, and Blue Azores in Portugal. Their collective efforts underscore the interdisciplinary and transnational dimension essential to addressing the complexities of ocean governance in the 21st century.

As the marine science community continues to advocate for more equitable and scientifically robust approaches to ocean management, studies like this one by the UCSB-led team pave the way toward reframing marine spatial planning as not just a scientific or economic exercise, but as a socially just endeavor capable of honoring diverse ocean users and fostering sustainable futures.
