Sri Lanka, strategically situated in the Indian Ocean, is deeply intertwined with maritime activities. Its location along major shipping routes has made it a critical node for global trade. However, as a small island state, it faces growing threats from climate change. The island nation is particularly vulnerable to rising sea levels, extreme weather events, and other environmental shifts that intensify maritime security risks.

In the broader Indian Ocean Region (IOR), many island states, like Sri Lanka, share common vulnerabilities due to their reliance on maritime resources. They depend on the ocean for livelihoods through fishing, tourism, and trade. Climate change disrupts these activities, leading to resource scarcity and the amplification of illegal fishing and maritime crime.

As sea temperatures rise, fish populations shift, often resulting in increased competition for dwindling stocks. This competition can fuel illegal fishing, further threatening economic stability. Additionally, rising sea levels endanger coastal infrastructure, including ports and naval bases, which are vital for both trade and security. The displacement of coastal communities due to climate-induced erosion and flooding is another significant concern, often leading to human trafficking and migration.

Sri Lanka’s experience highlights the need for robust adaptation strategies to counter these threats. The country has taken proactive steps, including launching its Climate Prosperity Plan, restoring mangrove ecosystems, and enhancing coastal resilience. The

Sri Lankan Navy plays a crucial role in safeguarding maritime interests by increasing patrols, intercepting illegal activities, and collaborating with international partners on counter-piracy and trafficking efforts.

For island states in the IOR, Sri Lanka serves as a case study for addressing the complex interplay between climate change and maritime security. Regional cooperation, policy integration, and community-led adaptation are essential to building resilience and ensuring long-term stability in these vulnerable regions. By taking a holistic approach, island states can better navigate the challenges posed by climate change and secure their maritime futures.

Strengthening Adaptation and Regional Cooperation

Building on its proactive measures, Sri Lanka underscores the importance of regional collaboration and a comprehensive approach to tackling climate change impacts on maritime security. Given the interconnectedness of island nations in the Indian Ocean Region (IOR), collective efforts are crucial for strengthening resilience and safeguarding maritime interests.

Sustainable Fisheries and Blue Economy Diversification

Sri Lanka’s experience highlights the importance of sustainable fisheries management. Overfishing due to climate change-induced shifts in marine ecosystems is a growing concern across the region. Collaborating with neighboring countries to adopt sustainable fishing practices and enforce regulations can prevent resource depletion and mitigate conflicts. Additionally, diversifying the blue economy—by investing in renewable energy, marine research, and ecotourism—can reduce dependence on vulnerable sectors like traditional fisheries and tourism.

Climate-Resilient Infrastructure and Coastal Management

As climate-induced risks, such as sea-level rise and extreme weather, threaten critical coastal infrastructure, Sri Lanka’s focus on climate-resilient planning offers valuable lessons for other island states. Investments in strengthening ports, naval bases, and coastal surveillance systems are essential for maintaining both economic stability and maritime security.

Sri Lanka’s efforts in restoring mangroves and protecting coral reefs serve as practical examples of nature-based solutions that enhance coastal resilience while supporting livelihoods.

Community-Led Adaptation and Local Empowerment

Engaging local communities in climate adaptation efforts is another vital component of resilience building. Sri Lanka’s mangrove restoration projects and coastal conservation initiatives demonstrate how empowering local populations can lead to more sustainable outcomes. Island states across the IOR can replicate this model by integrating local knowledge and participation into broader climate adaptation strategies, fostering stronger social cohesion and environmental stewardship.

Joint Maritime Operations and International Cooperation

Sri Lanka’s active participation in joint maritime operations and regional security forums, such as the Indian Ocean Rim Association (IORA), showcases the importance of international cooperation. Strengthening regional ties through coordinated patrols, information sharing, and capacity building can help island states effectively combat transnational crimes, such as piracy, smuggling, and illegal fishing. The establishment of agreements like the Djibouti Code of Conduct is an important step toward enhancing maritime security and ensuring the safe passage of global trade.

Charting a Climate-Resilient Maritime Future

As the effects of climate change continue to reshape the maritime landscape, Sri Lanka’s comprehensive approach to adaptation and security serves as a roadmap for other island nations. By prioritizing sustainability, fostering regional cooperation, and empowering local communities, the IOR can mitigate the threats posed by climate change and ensure long-term security for its maritime domain.

In conclusion, Sri Lanka’s proactive strategies in addressing the nexus between climate change and maritime security provide a blueprint for island states in the Indian Ocean Region. Through collaborative efforts and innovative adaptation measures, these nations can navigate the complex challenges ahead and secure a more resilient future for their people and their maritime economies.
