How Science and Partnership Are Protecting the Western Indian Ocean
Scientific evidence and strategic collaboration are creating sustainable solutions for marine ecosystems and coastal communities
Explore the ImpactIntroduction
Beneath the warm, azure waters of the Western Indian Ocean lies a world of breathtaking coral reefs, majestic mangroves, and abundant marine life that supports the livelihoods of millions of people along the eastern coast of Africa.
Yet this vital ecosystem faces increasing threats from climate change, overfishing, and pollution. Protecting this precious resource requires more than just good intentions—it demands scientific evidence guiding effective policy.
This is where a unique partnership, supported by the Swedish International Development Cooperation Agency (Sida), is making waves. For over two decades, Sweden has committed to strengthening marine research and conservation in this vulnerable region. Through a strategic focus on bridging the gap between scientists and decision-makers, Sida is helping ensure that policy decisions are informed by the best available science, securing a sustainable future for both the Western Indian Ocean's ecosystems and the communities that depend on them 2 .

The Science-Policy Bridge: Why It Matters
The Critical Divide
In an ideal world, every environmental policy would be grounded in robust scientific evidence. In reality, a significant gap often exists between researchers and policymakers. Scientists typically work on multi-year research cycles, carefully collecting and analyzing data before drawing conclusions. Policymakers, by contrast, often need to make rapid decisions in response to immediate challenges, balancing scientific evidence with political, economic, and social considerations 3 .
This divergence creates what experts call a problematic "science-policy interface." As one policy briefing notes, researchers frequently face challenges in "supporting policy uptake of their findings" despite the growing understanding of how critical evidence-based policymaking is for effective environmental responses 3 . The challenges include mismatched timeframes, difficulties in navigating policy processes, and a lack of mutual understanding between these two communities 3 .
Science vs. Policy Timelines
The mismatch between scientific research cycles and policy decision timelines creates challenges for evidence-based governance.
Sida's Strategic Investment in Knowledge
Recognizing these challenges, Sida has made a substantial commitment to strengthening the scientific foundation of marine governance in the Western Indian Ocean. In 2023, Sweden reaffirmed its long-standing support for the region by pledging 70 million Swedish Kronor (approximately US$6,400,000) to be distributed over three years through the Western Indian Ocean Marine Science Association (WIOMSA) 2 .
This funding supports WIOMSA's "Sustainable Blue Future in the Western Indian Ocean" program, also known as SCALABLE, which focuses on "institutional strengthening through science, capacity and assimilation for a sustainable blue future" 2 . The program aims to develop ocean professionals across the region, including scientists, early career professionals, marine resource managers, governments, and local communities 2 .
| Focus Area | Description | Expected Outcome |
|---|---|---|
| Multi-stakeholder Exchanges | Facilitating dialogue between researchers, policymakers, communities, and private sector | Inclusive knowledge generation and comprehensive policies |
| Capacity Building | Developing skills of scientists, early career professionals, and resource managers | Stronger regional expertise in marine science and management |
| Co-development Processes | Jointly creating solutions between researchers and end-users | More relevant and applicable research outcomes |
| Integrative Scientific Assessments | Comprehensive evaluation of marine environment | Better understanding of ecosystem status and trends |
Sida in Action: Case Studies from the Western Indian Ocean
The WIO Symphony: A Tool for Marine Planning
One remarkable outcome of Sida's engagement is the development of WIO Symphony, a sophisticated tool for measuring and forecasting cumulative environmental impacts in the Western Indian Ocean. This initiative represents a practical application of science-policy bridging, co-created through collaboration between the Nairobi Convention, its ten Member States, and the Swedish Agency for Marine and Water Management (SwAM) 4 .
WIO Symphony supports marine spatial planning by assessing environmental impacts from human activities, allowing users to "visualize data in order to test and compare different planning scenarios" 4 . What makes this tool particularly effective is the involvement of representatives from each of the ten member states in its development, ensuring the final product is "tailored to the specific needs of the end users" 4 . This approach of co-creation "brings science closer to policy" and provides a "tangible transparent tool for marine managers and planners from the region" 4 .

Empowering Small-Scale Fisheries Through Regional Networks
In June 2025, a stakeholders' consultative workshop in Mombasa, Kenya, led to the formation of the Western Indian Ocean Network for Small-Scale Octopus Fisheries (WION-SOF) 6 . Supported by Sida, this initiative brought together 35 participants from Kenya, Tanzania, Comoros, and Madagascar, including NGOs, academics, government representatives, and local fishers 6 .
The network aims to address critical challenges in octopus fisheries, which play a "vital role in the livelihoods of coastal communities," particularly for women 6 . By creating a platform for knowledge-sharing, capacity building, and advocacy, WION-SOF represents another practical example of how Sida's support helps bridge different types of knowledge—scientific research, traditional wisdom, and policy expertise—to create more sustainable outcomes.

| Benefit | Mechanism | Impact |
|---|---|---|
| Knowledge Sharing | Platform for exchanging best practices and research findings | Improved fishing techniques and resource management |
| Gender Equality | Focus on enhancing women's role in fisheries | More equitable benefits and recognition of women's contributions |
| Market Access | Collective bargaining and reduced post-harvest losses | Better incomes for fishing communities |
| Policy Influence | Unified voice advocating for sustainable practices | More supportive regulatory environment |
Building Capacity Through Grants and Scientific Exchange
Beyond specific tools and networks, Sida's support enables WIOMSA to administer grant programs that drive innovation in marine research. The Innovation for Sustainability Grant programme supports "transformative, paradigm-shifting concepts and approaches" that address marine and coastal environmental issues 1 .
This program explicitly encourages "collaboration between different actors, including researchers, communities, government authorities and the private sector," recognizing that complex sustainability challenges require diverse perspectives and expertise 1 . The upcoming 13th WIOMSA Scientific Symposium in Mombasa in September-October 2025 provides another platform for such exchange, showcasing "the latest research results and key developments" in the region 8 .
Capacity Building
Developing the next generation of marine scientists and professionals across the region.

Conclusion: A Model for Sustainable Ocean Governance
Sida's involvement in supporting research in the Western Indian Ocean offers a compelling model for how international development cooperation can effectively bridge the gap between science and policy.
By taking a long-term perspective—with support spanning over two decades—and focusing on building regional capacity rather than imposing external solutions, this partnership has created a sustainable foundation for evidence-based ocean governance 2 .
The success of this approach lies in its multifaceted strategy: developing practical tools like WIO Symphony for decision-makers 4 , creating collaborative networks such as WION-SOF for knowledge exchange 6 , and building the next generation of marine professionals through grants and scientific symposia 1 8 . Underpinning all these efforts is a recognition that protecting the Western Indian Ocean requires not just excellent science, but science that is relevant, accessible, and useful to those tasked with making decisions about its future.
As climate change and other human impacts continue to threaten marine ecosystems worldwide, the lessons from Sida's engagement in the Western Indian Ocean—emphasizing collaboration, capacity building, and communication across the science-policy divide—offer valuable insights for other regions striving to protect their blue natural heritage while supporting coastal communities.
