This episode of The Weekly Tradecast looks at the challenges of sustainable fishing with UNCTAD legal expert David Vivas. From farmed prawns to wild-caught mackerel, the fishing industry is a vital source of food – and livelihoods – all over the world. If the seas can sustain it, fisheries output is expected to top 200 million tonnes by 2030 as the global population grows.  But the industry also faces concerns about labour rights and environmental damage – including overfishing and high carbon emissions from trawlers and factories.  Can fishing ever be sustainable in an ever-hungrier world? Listen in to UNCTAD’s David Vivas to find out what we can do.
