Sri Lanka Ties Coastal Cleanup to Indian Ocean Marine Heatwaves

Sri Lanka's national Coastal Cleanup Day programmes this year carried a broader environmental message: that the health of the coast cannot be separated from what happens inland. Among the activities was a climate-change awareness session on Indian Ocean marine heatwaves, conducted with the Ocean University of Sri Lanka.

The scale of the national effort was reflected in participation from government institutions, the Navy, the Coast Guard, private companies, environmental organizations and community groups. Presentations and discussions covered coastal conservation and resource management, marine environmental protection, fisheries and aquatic resources, and climate resilience.

Speakers argued that Sri Lanka's environmental problems cannot be solved by institutions working independently. One professor noted that institutions have boundaries while nature does not — coastal ecosystems, the ocean, fisheries and aquaculture function as an interconnected system, yet are typically governed through separate mandates.

The event reflects a growing emphasis in island and coastal states on treating marine heatwaves as a practical concern, not just a scientific one. Heatwaves can stress coral reefs, displace fish stocks and disrupt the fisheries that coastal communities depend on — impacts that are measured in livelihoods as much as in degrees.
