The blue economy is a term used to describe the sustainable use of ocean and coastal resources for economic growth. It encompasses a wide range of sectors, including fisheries, aquaculture, tourism, maritime transportation, renewable energy, and coastal infrastructure development. The ocean economy supports 90% of global trade and provides millions of jobs. It includes shipping, tourism, and offshore energy valued at US$24 trillion. Marine fisheries and reefs, sea grass and mangroves are worth US$6.9 trillion; trade and transport US$5.2 trillion; and coastline productivity and carbon absorption US4$12.1 trillion. The blue economy is estimated to be worth more than US$1.5 trillion per year globally, and it provides over 30 million jobs. It is also a vital source of food and nutrition for billions of people around the world. The blue economy recognizes the importance of oceans and their resources to the global economy and society, and it seeks to promote economic development while also ensuring the long-term sustainability of ocean resources and the health of marine ecosystems. Nigeria coastline stretches for 420 nautical miles and covers an Exclusive Economic Zone of 200 nautical miles. Its maritime interests span the Gulf of Guinea, covering roughly 574,800 square nautical miles with a 2,874 nautical mile coastline. This paper will focus on the opportunities around blue economies and marine resources with significant potential to create jobs, improve livelihoods, and generate income from fisheries, aquaculture, fish reef, tourism, shipping and renewable energy. The paper will also address the issues of governance, safety and security, rule of law and transparency, respect for human rights, sustainable economic opportunity and human development.
