The global COVID-19 pandemic gives us all pause about what the future holds. Our focus and attention are on all those hurt by this terrible disease. But for many of us, this is also a time of deep reflection about society and the world we’ll inhabit when this scourge is over. So for me, it’s also a moment to reflect on the prospects for the ocean, one of the planet’s fundamental life-support systems — making it vital to human health and well-being.
A just-released article in Nature, by Professor Carlos Duarte of King Abdullah University of Science and Technology in Saudi Arabia and colleagues, argues that the global ocean can once again return to abundance, rebounding from overfishing and pollution by 2050, if humanity puts its shoulder to the wheel and redoubles efforts across all types of threats. We emphatically agree.
Here, we dive into what such lofty ambitions might require, through one of the key lenses that Duarte and company identify: sustainable fishing.
First, peer-reviewed research shows very clearly that sustainable fisheries management works. That should come as no surprise. Our own work with University of California, Santa Barbara and others (Costello et al., 2016) modelling the world’s fisheries showed that the “upside” of informed and effective management rapidly outweighs the downside of unsustainable fishing (which would otherwise deplete more than 85% of fish populations). Our modelling shows that such management approaches would allow full rebuilding of most stocks (and total global fish abundance) in less than a decade — restoring fish as a valuable asset both for nature and human needs. This exciting finding was recently underscored by a deep and systemic analysis (Hilborn et al., 2020) showing that, in fact, when good management is put in place, fish and fisheries respond impressively.
