Sustainable Coastal Waste Governance through the Lens of Fishing Families: Evidence from Sebatik Island
This study examines the socio-economic vulnerabilities and waste management challenges faced by fishing families on Sebatik Island, concluding that sustainable coastal waste governance requires integrating poverty alleviation with community-based systems, economic diversification, capacity building, and cross-border collaboration.

The ocean does not recognize borders. A plastic bottle discarded on a shoreline in one country can drift across the water and wash up on a beach in another, carried by the same currents that bring fish to local nets. This reality makes managing coastal waste a complex challenge, particularly in regions where two nations share a single ecosystem. For decades, experts have understood that cleaning up the ocean requires more than just better trash cans or stricter laws; it demands that the people living along the coast are part of the solution. However, a persistent gap often exists between what communities know they should do and what they are actually able to do. When people are struggling to feed their families or lack the tools to sort their trash, even the strongest environmental awareness can fail to translate into action. This disconnect is the central puzzle facing coastal governance in many parts of the world, especially in developing nations where economic hardship and environmental degradation often feed into one another.
A team of researchers from Indonesia and Malaysia recently turned their attention to Sebatik Island, a unique landmass split between the two countries, to understand why this gap exists and how to bridge it. The island serves as a natural laboratory where Indonesian and Malaysian fishing families live side by side, sharing the same waters, the same tides, and the same piles of trash. The researchers wanted to move beyond simple statistics to see the problem through the eyes of the fishermen themselves. They asked a fundamental question: if these communities know that waste is harming their ocean, why does the waste keep piling up, and what would it actually take to change the situation?
To find the answer, the team spent time living and working alongside 159 fishing households across seven villages on both sides of the border. They did not just hand out surveys; they listened to stories, observed daily routines, and held group discussions to understand the real pressures these families face. What they discovered was a picture of deep vulnerability. The majority of these fishermen rely almost entirely on the sea for their income, with very few having other jobs to fall back on when the catch is poor. On the Indonesian side of the island, more than sixty percent of the fishermen earn less than half of the official minimum wage for their region. On the Malaysian side, while incomes are slightly higher, the families still live on the edge, often relying on informal lenders to survive between fishing trips. Many of these households are large, with several children and dependents, meaning a single income must stretch to cover food, school fees, and healthcare.
This economic fragility creates a powerful barrier to environmental action. The researchers found that the fishermen are not unaware of the problem. In fact, more than eighty percent of those surveyed believe that managing coastal waste is critically important. They see the trash clogging their nets and polluting their waters. Yet, despite this high level of awareness, the actual practice of managing waste remains weak. The study identified a stark mismatch: the community is ready and willing to help, but they lack the support, the training, and the financial safety net to turn that willingness into effective action. Without access to proper collection facilities, without knowledge of how to turn waste into something useful, and without the money to invest in better equipment, the trash simply stays where it is.
The composition of the waste itself tells a story of both the problem and a potential solution. Plastic bottles make up the largest share of the trash, accounting for more than half of all waste generated in the area. Interestingly, the researchers observed that some locals already reuse these bottles for seaweed farming, showing a natural instinct to repurpose materials. However, without proper guidance, this reuse can sometimes lead to new problems, such as the plastic breaking down into tiny, harmful particles that enter the food chain. The study suggests that this existing habit of reuse could be the foundation for a broader solution, but only if it is supported by proper education and infrastructure.
The researchers argue that the current approach to solving this problem is flawed because it treats waste management as a purely technical issue. Governments often focus on building more trucks or passing new laws, assuming that if the infrastructure is there, the community will use it. The findings from Sebatik Island show that this assumption is incorrect. When a family is struggling to put food on the table, a new trash bin does not solve the immediate crisis. The study concludes that for waste management to work, it must be integrated with efforts to improve the economic lives of the fishermen. This means creating programs that not only teach people how to sort and recycle but also help them earn money from the process, perhaps by turning waste into building materials or other products.
Furthermore, because the ocean flows freely between Indonesia and Malaysia, the study emphasizes that one country cannot solve this alone. The waste generated on one side of the island inevitably affects the other. The researchers point out that without strong cooperation between the two governments to coordinate their policies and share resources, local efforts will always be incomplete. They propose a new way forward that combines poverty alleviation with environmental protection, creating a system where cleaning the coast also helps lift families out of economic hardship.
Ultimately, the paper suggests that the path to a cleaner coast lies not in forcing communities to change, but in empowering them to change. By addressing the root causes of vulnerability—low income, lack of education, and limited access to capital—governments can create an environment where sustainable waste management becomes a natural choice rather than a burden. The story of Sebatik Island is a reminder that in the fight against ocean pollution, the most effective tool is not a bulldozer or a law, but a community that is strong enough, supported enough, and informed enough to take care of its own home.
