Nigeria is situated on the on the western Indian Ocean, where coral reefs are a vital component of marine ecosystems that support traditional fishing and livelihoods in coastal communities, as well as commercial seafood production. One of the fastest and most scalable approaches for marine ecosystem service and aquaculture is the cultivation of reefs using prefabricated structures.
In the global climate change context, carbon dioxide removal at gigaton scale is required to retain any hope of achieving the Parish climate accord objectives. Nigeria has an extensive coastline, with an Exclusive Economic Zone (EEZ) greater than 200,000 square kilometers. Using 1% for seaweed cultivation could remove about 7.6 million tons per year of carbon dioxide (CO2) from seawater, which is actual greenhouse gas removal or reduction.
This paper aim to focus on the rapid expand coral reef and seaweed ecosystems as part of regenerative marine aquaculture which provides climate-proof food security as part of the broader blue economy in Nigeria.
