Seaweed farming could reduce the impacts of climate change

By Ana Carolina Dias Terra and Thauan Santos |

The marine farming taking place in Pamban Island, located in India, could contribute for climate safety. Seaweed production in the coastal villages of the island has increased considerably. Among the many benefits, the main one is the capacity to reduce carbon gas emission in the enviroment, which can occur in three different ways: sedimentation of CO2 below the sea surface, reduction of emissions in agriculture through the use of bio-fertiliser made with seadweed and the transformation of algae into biofuels. In addition to that, the Blue Revolution could minimize the shortage of food in the area. Despite the possible negative impacts on coral reefs, seaweed farming could generate positive socioeconomic impacts in the communities.

Impacts on Defense and Security: Seaweed farming in a large scale could point out towards the reduction of climate change that has placed various forms of life at risk. This initiative could considerably increase climate security. In addition to that, people from coastal areas could benefit from the production and trading activities of the resource.
