Every fishmonger at Tema fishing harbour knows the pattern: canoes travel farther, remain at sea longer and return with fewer fish. Premix fuel costs rise, nets fall apart, and banks refuse loans, calling fishing “too risky”. Meanwhile, Ghana imports fish to feed its population. This is not about an ocean without value; it is about an ocean without investment.
On 19 September 2026 in Manila, Masato Kanda, president of the Asian Development Bank (ADB), announced the bank would mobilise up to $6 billion from 2026 to 2030 for the ASEAN Blue Economy Initiative. The funds will target fisheries, aquaculture, coastal resilience, port-linked value chains, and tackling land-based waste and wastewater polluting the sea. Kanda’s message was clear: the ocean is not only an environmental concern but the economic foundation of Southeast Asia.
Southeast Asia produces about one fifth of the world’s fisheries and aquaculture output. Its ports, coastal logistics, and tourism employ millions and carry significant trade. Yet, plastic pollution, overfishing, and destruction of mangroves and reefs threaten this wealth. The ADB estimates coastal floods could cost the region $11.5 billion annually. Investing $6 billion to protect these assets is a business decision, not an act of charity.
This initiative is part of a larger $30 billion package the ADB has promised for ASEAN priorities by 2030, signalling a shift of ocean concerns from the margins to the centre of development finance. It treats sea and land as one system, investing in upstream waste and water services because most marine pollution originates in cities. The plan is designed to attract private capital through innovative finance, with public money first making projects bankable.
Africa’s ocean wealth contrasts sharply with its investment. According to the State of Africa’s Blue Economy 2026 report presented at the Third Africa Blue Economy Conference in Luanda in July, the continent’s blue economy is worth over $298 billion annually and employs more than 40 million people. About 200 million Africans depend on fish from their seas, and roughly 90% of the continent’s trade moves by sea. Yet, as the African Union admitted, many blue economy projects still rely on external agencies, and a gap exists between policy and delivered projects.
Africa has strategies. The African Union adopted the Africa Blue Economy Strategy in 2019. The African Development Bank supports blue economy skills, including a new marine science scholarship with Shanghai Ocean University in 2026. Still, Africa lacks a dedicated continental blue investment window on the scale the ADB has announced. Calls have grown for the AfDB to fill this gap.
African countries have shown what is possible. Seychelles converted part of its national debt into ocean protection through a debt-for-nature swap in 2016 and issued the world’s first sovereign blue bond in 2018, backed by the World Bank. Gabon completed a debt-for-nature conversion in 2023, freeing funds for marine conservation. These deals were small compared to Asian standards but proved African nations can pioneer blue finance when structures are right.
Ghana has taken steps. Parliament passed the Fisheries and Aquaculture Act, 2025 (Act 1146). The country declared its first Marine Protected Area at Cape Three Points. In December 2025, Cabinet approved a National Blue Economy Strategy based on six pillars, including blue finance, and agreed to establish a Blue Economy Commission. In October 2025, the Vice President announced an Aquaculture Development Fund. These form a foundation.
Yet, challenges persist. Ghana’s fish supply deficit exceeded 640,000 tonnes in 2021, with an annual supply gap estimated at around $800 million. Aquaculture output has grown to about 100,000 tonnes yearly, but farmers face high feed costs, disease, and lack of credit. Coastal erosion affects the shoreline from Keta to Axim. The National Blue Economy Strategy remains uncosted, and no clear plan has been communicated on financing. Without a price tag, the strategy remains a wish list.
To close the gap, Africa needs an Africa Blue Economy Facility. The AfDB should lead a blue investment window of at least $6 billion from 2027 to 2031, co-financed with Afreximbank, the Africa Finance Corporation, regional development banks, and climate funds. The focus should be on fisheries, aquaculture, ports, coastal resilience, and pollution control.
Building a pipeline of bankable projects is essential. A continental project preparation fund should help countries transform plans into investment-ready proposals with clear revenues, risks, and returns. Africa must also scale up blue bonds, debt-for-nature swaps, guarantees, and blended finance, learning from Seychelles and Gabon, so public money attracts private capital rather than standing alone. Investing in ocean data is critical. No investor will fund what cannot be measured. Shared stock assessments, coastal mapping, and pollution monitoring should be treated as core infrastructure.
For Ghana, the immediate task is clear: put a price on the National Blue Economy Strategy. The government should cost the strategy and publish a Ghana Blue Investment Plan, with an ambition of $6 billion. Without this, the ocean will remain an untapped resource while fishmongers at Tema watch their canoes return empty.
