Abstract
This article examines the intersection of sustainable fisheries, economic growth, and ocean conservation in Nauru, a small Pacific Island nation heavily reliant on marine resources. With a focus on the challenges posed by overfishing, environmental degradation, and economic dependency on fishing revenues, the paper explores how Nauru can balance these competing interests. The role of intergovernmental organizations and treaties, such as the Nauru Agreement Concerning Cooperation in the Management of Fisheries of Common Interest, is analyzed as a framework for sustainable management. Through a situational analysis of Nauru’s fisheries and a review of global literature on sustainable fishing practices, this study highlights the need for integrated policies that prioritize both ecological health and economic stability. Recommendations include community-based fisheries management, enhanced regional cooperation, and the adoption of technological innovations for monitoring and enforcement. The paper concludes that sustainable fisheries in Nauru are achievable through collaborative governance and a commitment to long-term conservation goals.
Introduction
Nauru, a small island nation in the Pacific Ocean, spans a mere 21 square kilometers and supports a population of approximately 12,000. Despite its size, Nauru plays a significant role in the global tuna fishery, as part of the Parties to the Nauru Agreement (PNA), which collectively controls a substantial portion of the world’s tuna supply. Fisheries, particularly through licensing fees for foreign vessels, constitute a critical pillar of Nauru’s economy. However, this dependence on marine resources raises pressing concerns about overfishing, habitat degradation, and the long-term sustainability of the nation’s ocean ecosystems.
The dual challenge of fostering economic growth while ensuring ocean conservation is not unique to Nauru but is particularly acute given the country’s limited land resources and geographical isolation. Historically, Nauru’s economic narrative has been one of resource exploitation, most notably through phosphate mining, which left much of the island environmentally degraded. Today, as the nation pivots toward marine resources, there is an urgent need to avoid repeating past mistakes by embedding sustainability into fisheries management. This paper seeks to address how Nauru can balance economic imperatives with the conservation of its marine ecosystems, examining the role of intergovernmental cooperation and treaties in shaping sustainable outcomes.
The study is structured to provide a comprehensive analysis of the issue. A situational analysis of Nauru’s fisheries sector highlights current practices and challenges. This is followed by a literature review exploring global insights into sustainable fisheries. The discussion integrates these findings with Nauru’s unique context, while recommendations offer actionable strategies for policymakers. Finally, the conclusion synthesizes the key arguments and underscores the importance of regional and international collaboration.
Situational Analysis
Nauru’s economy is characterized by a narrow revenue base, with fishing license fees representing a significant income stream alongside residual phosphate processing and revenue from the Australian Regional Processing Center for asylum seekers. According to reports from the International Monetary Fund (IMF), the nation’s small size and remoteness exacerbate its vulnerability to external shocks, making economic diversification challenging (IMF, 2023). Fisheries, therefore, are not merely an economic resource but a lifeline for Nauru’s financial stability.
As a member of the Parties to the Nauru Agreement (PNA), Nauru collaborates with seven other Pacific Island nations to manage tuna stocks in the western and central Pacific, which account for approximately 25–30% of the global tuna supply (PNA, 2010). The PNA has implemented measures such as the Vessel Day Scheme (VDS), which limits fishing effort by allocating a set number of fishing days to foreign vessels. Revenues from these licenses are a critical source of income for Nauru, but they also highlight a dependency on foreign fishing fleets, often operating with limited local oversight.
Environmentally, Nauru faces significant challenges. The coastal areas, where the population resides due to inland degradation from phosphate mining, are vulnerable to climate change impacts such as rising sea levels and ocean acidification. These factors threaten marine biodiversity and fish stocks, compounding the risks of overfishing. Recent initiatives, such as community-based coastal fisheries management supported by programs like the Kiwa Initiative, signal a growing awareness of sustainability needs (Kiwa Initiative, 2025). However, enforcement capacity remains limited, and data on local fish stocks are scarce, hindering evidence-based management.
From a governance perspective, Nauru’s involvement in intergovernmental frameworks like the PNA and the Pacific Islands Forum Fisheries Agency (FFA) provides a platform for regional cooperation. These organizations facilitate coordinated policies on licensing, monitoring, and enforcement. Yet, translating regional agreements into local action remains a hurdle, given Nauru’s resource constraints and competing economic priorities.
Literature Review
The concept of sustainable fisheries has garnered extensive attention in global academic discourse, driven by the recognition that fish stocks are finite resources critical to food security, livelihoods, and cultural identity, especially in Small Island Developing States (SIDS). According to the Food and Agriculture Organization (FAO), over 30% of global fish stocks are overfished, necessitating urgent action to restore marine ecosystems (FAO, 2020). Sustainable fisheries management, therefore, involves not only limiting catch levels but also preserving marine habitats, reducing bycatch, and ensuring equitable benefits for coastal communities.
One prominent framework for sustainability is the ecosystem-based approach, which emphasizes the interconnectedness of marine species and habitats. Pauly et al. (2002) argue that traditional single-species management often fails to account for broader ecological impacts, advocating instead for policies that integrate environmental, social, and economic dimensions. For Pacific Island nations like Nauru, this approach is particularly relevant given their reliance on tuna, a migratory species affected by regional fishing pressures.
Intergovernmental cooperation is frequently cited as a cornerstone of sustainable fisheries. The United Nations Convention on the Law of the Sea (UNCLOS) establishes legal frameworks for managing marine resources, including the obligation to cooperate on highly migratory species (United Nations, 1982). Regional agreements, such as the Nauru Agreement, build on this by tailoring conservation measures to specific contexts. Studies by Clark and Munro (2002) highlight that regional fisheries management organizations (RFMOs) can enhance compliance and reduce overfishing through collective enforcement mechanisms, though success depends on member states’ political will and capacity.
Economic incentives also play a critical role. The World Bank (2017) suggests that rights-based fisheries management, such as quotas or territorial use rights, can align economic interests with conservation goals by giving communities a stake in resource stewardship. However, in contexts like Nauru, where foreign fleets dominate, local benefits are often diluted, raising questions of equity and access.
Finally, technological advancements are increasingly recognized as tools for sustainability. Remote sensing, satellite tracking, and electronic monitoring systems can improve surveillance of fishing activities, particularly in remote regions (Dunn et al., 2018). Yet, the literature notes that such innovations require investment and capacity building, often beyond the means of small nations without international support.
Discussion
The case of Nauru encapsulates the broader challenges faced by SIDS in managing fisheries sustainably. Economically, fishing license fees are a vital revenue source, yet reliance on foreign vessels under the PNA framework risks prioritizing short-term gains over long-term ecological health. The Vessel Day Scheme, while innovative, has been critiqued for inconsistent enforcement and insufficient focus on local capacity building. For Nauru, the economic benefits of fisheries must be weighed against the potential depletion of tuna stocks, which could undermine future income and food security.
Environmentally, Nauru’s marine ecosystems are under strain from both local pressures and global phenomena like climate change. Ocean acidification and warming waters affect fish migration patterns, as noted in regional studies by the Pacific Community (SPC, 2019). Without robust conservation measures, such as marine protected areas (MPAs) or stricter catch limits, Nauru risks losing the very resource base that sustains its economy. This aligns with Pauly et al.’s (2002) ecosystem-based approach, which calls for holistic management beyond mere quotas.
Intergovernmental organizations and treaties offer a pathway forward. The Nauru Agreement, facilitated by the FFA, demonstrates the value of regional collaboration in setting standards for licensing and monitoring. Since its inception in 1982, the agreement has evolved to address conservation, as seen in the 2010 amendments strengthening fishing limits (PNA, 2010). Additionally, Nauru’s alignment with UNCLOS principles reinforces its obligation to manage shared stocks sustainably. However, translating these commitments into action requires overcoming domestic constraints, such as limited surveillance infrastructure and technical expertise.
Recent developments, such as the 2023 Biodiversity Beyond National Jurisdiction (BBNJ) Agreement, further underscore the need to integrate fisheries into broader conservation frameworks. While the BBNJ primarily addresses areas beyond national jurisdiction, its emphasis on holistic marine governance offers lessons for Nauru in harmonizing economic and ecological goals (Nature, 2025). Tensions remain, however, as separating fisheries from biodiversity agendas risks fragmented approaches, a concern echoed in global debates on ocean sustainability.
Community engagement is another critical dimension. Initiatives like the Kiwa project highlight the potential of local stewardship in coastal fisheries management (Kiwa Initiative, 2025). Empowering Nauruan communities to monitor and manage nearshore resources could reduce reliance on foreign fleets while fostering a conservation ethic. Yet, such programs must be scaled with government and international support to address systemic issues like data gaps and enforcement capacity.
In sum, Nauru’s fisheries sector illustrates the delicate balance between economic imperatives and environmental stewardship. While regional treaties and organizations provide a supportive framework, their effectiveness hinges on localized implementation and sustained investment in capacity building. The following recommendations aim to address these challenges with actionable strategies tailored to Nauru’s context.
Recommendations
1. Strengthen Community-Based Fisheries Management (CBFM): Building on initiatives like the Kiwa project, Nauru should prioritize CBFM to engage local communities in monitoring and managing coastal fisheries. This includes training programs on sustainable practices and establishing co-management structures between communities and government agencies. Such measures can enhance local ownership and reduce overfishing in nearshore waters.
2. Enhance Regional Cooperation through the PNA: Nauru must advocate for stricter enforcement of the Vessel Day Scheme within the PNA framework, including mandatory vessel monitoring systems (VMS) for all licensed foreign fleets. Additionally, PNA members should pool resources for joint surveillance operations, addressing Nauru’s individual capacity constraints.
3. Invest in Technological Solutions: With support from international partners, Nauru should adopt affordable technologies such as satellite tracking and electronic catch reporting to improve oversight of fishing activities. Capacity building in data analysis will be crucial to ensure these tools inform evidence-based policies.
4. Establish Marine Protected Areas (MPAs): Designating specific zones as MPAs can safeguard critical habitats and fish spawning grounds. While Nauru’s exclusive economic zone (EEZ) is vast, pilot MPAs near coastal areas can serve as a starting point, with community input on boundaries and regulations.
5. Diversify Economic Base: To reduce dependency on fishing revenues, Nauru should explore alternative livelihoods such as ecotourism and aquaculture, leveraging international funding for climate-resilient projects. This aligns with the United Nations Sustainable Development Goal 14 (Life Below Water), which emphasizes sustainable marine resource use for SIDS (United Nations, 2015).
6. Align with Global Treaties: Nauru should integrate principles from the BBNJ Agreement and UNCLOS into national policies, ensuring that fisheries management contributes to broader ocean conservation goals. This includes participating in international forums to advocate for SIDS-specific support in implementation.
These recommendations, while ambitious, are designed to be incremental and collaborative, recognizing Nauru’s resource limitations and the importance of external partnerships.
Conclusion
Sustainable fisheries in Nauru represent a critical intersection of economic growth and ocean conservation, reflecting broader challenges faced by SIDS globally. The nation’s reliance on fishing license fees underscores the economic stakes, yet the risks of overfishing and environmental degradation demand urgent action. Through frameworks like the Nauru Agreement and support from organizations such as the FFA, Nauru has access to regional mechanisms that can bolster sustainable management. However, translating these into effective local policies requires overcoming significant barriers in capacity, enforcement, and data availability.
This study has highlighted that sustainability in Nauru’s fisheries is not merely a technical issue but a governance and equity challenge. Community engagement, technological innovation, and alignment with global treaties offer pathways to balance competing interests. The recommendations provided—ranging from CBFM to economic diversification—aim to foster a future where Nauru’s marine resources support both livelihoods and biodiversity.
Ultimately, the success of sustainable fisheries in Nauru hinges on collaboration at multiple levels: local communities, regional partners, and international stakeholders must work in tandem. As global attention on ocean conservation grows, Nauru has an opportunity to model how small nations can lead in balancing economic and ecological priorities, contributing to the global agenda for sustainable seas.
