Overfishing is one of the greatest threatsto ocean health, yet for decades many governments have paid subsidies to their fishing fleets, helping them fish beyond levels that are biologically sustainable. Its time to end these harmful subsidies, some of which even support illegal fishing activities. Now, new case studies show that World Trade Organization (WTO) measures to end those harmful payments could help local fishers while increasing global catch.

Not all fisheries subsidies are harmful. Some, for example, might help artisanal fishers survive a lean season, and those payments should be maintained. But studies show that governments are spending $22.2 billion per year on payments that encourage overfishing. These subsidies, paid to help offset the costs of vessel fuel, upgrades, port renovations, and other expenses, enable primarily industrial fleets to fish farther from shore and longer than they otherwise would. A June 2018 study found that without government subsidies, as much as 54% of the present high-seas fishing grounds would be unprofitable.

Fortunately, the global community has recognized this problem and the need to address it: The United Nations Sustainable Development Goal 14 Target 6, which U.N. member governments agreed to in 2015, tasks the WTO with crafting an agreement to end harmful fisheries subsidies. WTO members were on track to finalize this deal at a June meeting but have postponed that conference due to COVID-19.

The new case studies provide the first practical evidence of how curbing subsidy-driven overfishing would improve fishery sustainability and benefit local fishers, their families, and their communities.

To produce the studies, the International Institute for Sustainable Development commissioned researchers to examine fish stock exploitation levels, governance regimes, revenue from landings, income from subsidies, and operating costs in three fisheries: shrimp in Latin America, sardinella in West Africa, and southern longline tuna in the Pacific. The researchers were then asked to examine the economic impacts of possible WTO disciplines, and options for managing these impacts.

Broadly, the studies found that reforming harmful fisheries subsidies could lead to higher yields for local fishers, which in turn could help provide more stable jobs, raise fishers incomes, reduce poverty, and improve food security in local communities.

Incomplete or inadequate reporting often allows governments to obscure the nature of their subsidy programs, creating challenges in evaluating their true impacts. But if governments commit to increased transparency and more complete notifications to the WTO of their subsidy programs, analysts and observers will gain a far better understanding of the potential effects of any new policy.

Here are some of the specific findings from the case studies.

In the Latin American shrimp fisheries:

Key takeaway: WTO disciplines could help artisanal fisheries compete with industrial vessels that may not be profitable without subsidies. Fuel and vessel maintenance subsidies represented 20% to 50% of income for industrial vessels in Mexico and Nicaragua, for example.

In the West African sardinella fishery:

Key takeaway: WTO disciplines could limit the harmful subsidies contributing to the overcapacity and overfishing of sardinella for both sectors. These subsidies cover the costs of fuel, certain capital costs, and access to other countries waters, as well as contribute to allowing illegal, unreported, and unregulated (IUU) fishing, mostly by foreign vessels. Previous studies have estimated that West African fishers are losing up to $2.3 billion in revenue each year due to IUU fishing in the region.

In the western and central Pacific longline tuna fishery:

Key takeaway: Though the impact of WTO disciplines would likely vary in different parts of the fishery, ending subsidies that contribute to overfishing and overcapacity could reduce the overall fishing effort and allow for Pacific island countries to better develop their domestic fishing industries.

WTO members still have a chance to reach a trade deal that could realize unprecedented benefits for the ocean. While new WTO measures might require transition periods to help vulnerable fishers mitigate potential short-term impacts of subsidy removal, meaningful subsidy prohibitions, coupled with improved fisheries management at the national level, could improve economic and environmental conditions in fisheries around the world.

The new case studies show that subsidy reform would improve ocean health and help fishing fleets operate sustainably far into the future.
