The UN is at the sea’s during a major UN conference on the subject this week, 27 June 2022 in Lisbon. All lights are red: rising temperatures, acidification, rising water and overfishing. In view of the latter, in addition to the international agreements that are beginning to be adopted, a solution that is more sustainable is presented: aquaculture.
With our special correspondent in Lisbon, Simon Roze
The production from fishing and aquaculture is approximately 214 million tonnes by 2020. It now exceeds catch fishing and is growing rapidly. Mankind is consuming more and more shellfish: 20 kilos per person and year on average was half as much in the 1960s.
“Sustainable growth in production in the sector since the 1990s has been mainly linked to growth in production in the aquaculture sector,” explains Marc Taconet of FAO, who worked on this report. This means that they are implementing a number of measures that will enable more important and sustainable production, environmentally and socially. “
Need for more sustainable aquaculture The FAO therefore recommends intensifying aquaculture at the expense of catch fishing. The latter always has particularly detrimental effects: one third of the fish stocks are not fished sustainably and this poor figure is increasing.
“The figures for overfishing presented by the FAO are frightening and we are heading for the wall,” worries Guillermo Antonio Crespo, a researcher at the Stockholm Resilience Center. “We continue to overfish, so is aquaculture the solution? Yes, it can be a source of nutrients. But not all of its forms are sustainable. It can lead to deterioration of mangroves or coastlines, so it needs infrastructure. It’s not that simple.”
The needs are growing, the methods are often unsustainable. In the face of this observation, the FAO calls for a change in practice in favor of what it calls a blue transformation.
It is a project to maintain fishing and to allow Gabon to eat more fish.
