The demand for food will continue to increase with an additional 2.7 billion mouths to feed expected by 2050. On land this is a problem that we cannot grow our way out of. Little or no additional land will come into production to meet these food demands, the only option is sustainable intensification. In the oceans however, it is possible to replicate in some small way, what has already been achieved very successfully on land and hence increase the oceans productivity in a similar manner.
Regions of oceanic upwelling typically produce extensive fisheries. Upwelling brings nutrients up from the deep ocean. Addition of nutrients from above the sea surface is an analogous process. The aim of Ocean Nourishment should be to produce a vibrant ecosystem, such as exists in many upwelling areas. Research is needed to better understand this analogy.
