The blue economy originates from the principle of sustainable development. With the deepening of international exchanges and research, its connotation has been continuously enriched, and interdisciplinary research (especially at the integration level) is crucial for case analysis.
Coasts and oceans constitute one of the most productive ecosystems on Earth, providing diverse services such as disaster prevention, climate regulation, carbon sequestration, fisheries, renewable energy, shipping, and tourism. They form the basis of global marine economic activities worth $3-5 trillion annually, with marine economy accounting for 15%-20% of GDP in some East Asian countries.
Since the 21st century, the blue economy has garnered increasing attention. Academic research has focused on multiple fields, and many countries have utilized it as a tool for economic growth and employment policies. The focus encompasses industries such as marine architecture, transportation, mineral development, shipbuilding, renewable energy, tourism, and fisheries. The role of marine information and science departments has also become increasingly prominent.
Under the traditional model, countries often develop their economies by exploiting marine resources, yet they often overlook the impact on the ecosystem. The blue economy advocates a more comprehensive vision, prioritizing sustainable growth and balancing human well-being, social equity, and environmental sustainability, similar to the green economy.
It not only brings economic opportunities, but also safeguards “blue” resources such as traditional lifestyles, carbon sequestration, and coastal resilience, helping to mitigate the impact of poverty and climate change on vulnerable countries.
Currently, the annual value of the global marine economy is approximately $1.5 trillion, making it the seventh largest economy in the world. It is projected to reach $3 trillion by 2030, with the total value of marine natural capital standing at around $24 trillion. Although small island nations have limited land, they are rich in marine resources, presenting both development opportunities and vulnerabilities to resource degradation.
Currently, sustainable development has become a strategic consideration for businesses and investors. Challenges such as population growth, climate change, and marine pollution pose multiple risks, and the value of businesses effectively managing these ecosystems could account for 25%-70% of their revenue.
The blue economy is widely recognized as a potential driver of sustainable regional growth, yet its definition and framework remain unclear to businesses. The report focuses on its development and significance in East Asia, providing a practical framework for businesses. It surveys local companies, analyzes trends, risks, and opportunities in nine key industries, and explores influencing factors such as governance and investment.
Coastal ecosystems are facing multiple threats such as overfishing and pollution. According to data from the United Nations Development Programme, the global annual loss due to these threats ranges from $35 billion to $940 billion, while there is a funding gap of at least $300 billion (potentially reaching trillions of dollars) for ecological protection. Currently, the eight East Asian countries have invested approximately $10 billion in relevant departments for coastal integrated management. The report proposes suggestions for increasing investment by analyzing the sources of funding.
As a maritime nation, the United States has 40% of its population residing in coastal communities. In 2019, the blue economy contributed $397 billion in GDP and provided 2.4 million jobs, growing faster than the national economy. From 2014 to 2019, the GDP of the marine-related industries grew by 4.2% (exceeding the overall GDP growth rate of 2.2%). In 2018, seaport economic activities reached $5.4 trillion (nearly 26% of U.S. GDP). It is estimated that maritime trade demand will double by 2030. If the coastal counties in the United States were considered as independent countries, their GDP would rank third globally.
To build a new blue economy, it is necessary to promote marine technology, sustainable development, and logistics innovation, including improving marine data collection and dissemination, balancing growth and ecological protection, while addressing social challenges, stimulating innovation, and ensuring fairness.
It is estimated that the global population will reach 9 billion by 2050, leading to an increase in demand for fossil fuels and necessitating the exploration of alternative energy sources. Marine renewable energy (“blue energy”) holds great potential, utilizing resources such as wind and waves. It is also necessary to integrate offshore oil and gas with renewable energy communities to tap into the potential of the oil and gas industry in the Indian Ocean region.
Seaports and shipping play a pivotal role in the blue economy, yet trade distribution in the Indian Ocean region is uneven, with some countries facing challenges such as inadequate infrastructure. Regional cooperation is crucial to overcome these bottlenecks.
Marine biotechnology (blue biotechnology) holds vast prospects, as it can promote sustainable aquaculture, develop marine renewable energy, explore the application of marine compounds in fields such as medicine, and also assist in marine monitoring and restoration.
Marine tourism holds significant importance for developing countries. In 2012, international tourists reached 1.035 billion, generating revenue of USD 1.3 trillion. With an expected growth of 3%-4% in 2013, it also faces environmental pressures. Tourism forms such as whale watching have emerged in the IORA region, necessitating the assurance of their sustainability.
Population growth and urbanization exacerbate marine pollution, resulting in over 400 “dead zones” worldwide, covering an area of over 240,000 square kilometers. Plastic waste poses a threat to the food chain. International mechanisms need to be strengthened and implemented, balancing the costs and benefits of governance.
The development of the blue economy requires responsibilities from all countries and international cooperation, including improving governance mechanisms, technology transfer, capacity building, etc. Research provides a scientific foundation for cooperation.
In preparation for the 2014 Samoa Conference on Small Island Developing States, Seychelles and other countries advocated for the inclusion of the blue economy in the international agenda, which received support from multiple international conferences. A “Blue Summit” is planned to be held in Abu Dhabi in January 2014, aiming to facilitate the formation of an internationally recognized blue economy document and promote it as a unique model complementary to the green economy.
Despite the immense potential of the blue economy, it has yet to be fully integrated into practice. Innovative policies, technologies, and financing tools are needed to promote cooperation and resource management, encourage investment in emerging areas, and develop innovative financial methods to accelerate the transition to a sustainable blue economy.
