The Wierderij, a Wageningen UR test site where researchers are experimenting with sustainable seaweed cultivation. An idea brought in by Willem Brandenburg, DLO researcher at Plant Research International (PRI), who sees it as a first step towards a new kind of crop farming. At sea.
Brandenburg has a vision for 2050. What he envisages is people growing enormous quantities of seaweed out at sea, sustainably as well as intensively. To this end, developments which on land took 10,000 years must be compressed into a couple of decades. ‘At sea we are still hunter-gatherers,’ says Brandenburg. ‘We hunt fish and dump our waste in the oceans.’ He has a vision of people as farmers at sea. Minerals for ‘green chemistry’ can be extracted from seaweed, as well as the proteins which the world population – 9 billion by 2050 – is crying out for. ‘But with just 2 percent of the total ocean surface – twice the size of Portugal,’ says Brandenburg, ‘we can meet the global need for protein.’ And these marine farms can be combined with aquaculture and wind farms, for example.
