Abstract
Climate change is forcing farmers in Small Island Developing States to find novel methods to maintain crop productivity. Past practices using chemical fertilizers and poor waste management severely damaged many coastal areas, leading to an ecosystem shift towards algal dominance. In this chapter, the authors propose an approach to deal with this issue by devising methods which divert excess marine plant biomass into agricultural uses through conversion of the biomass to solid and liquid fertilizers. Seaweed-based fertilizers have already been tried with much success on crops in some developed countries, but these are expensive to import into Pacific Islands. The authors also suggest empowering local communities with the knowledge to convert marine plant biomass into ecologically friendly fertilizers. They will be able to save on the purchase of commercial fertilizers detrimental to the environment, while at the same time reducing the spread of seaweeds on their coral reefs. Farmers' incomes will increase.
