It's World Water Week this week, organised by SIWI - Stockholm International Water Institute. The Economist Group's World Ocean Initiative is an official outreach partner of the week. I am participating in today's Accelerator on Communication and Behaviour Change, aimed at highlighting levers that can speed up and intensify our impact.

I moderated this World Ocean Summit Insight Hour, which examined how to increase sustainability in aquaculture supply chains. It will highlight the role of retailers in influencing best-practice operations throughout the value chain. Speakers will identify key steps for seafood processors, fish farmers, feed suppliers and technology developers as they scale production.

Aquaculture is the fastest-growing food-production sector globally and is vital for feeding our growing population. But there are challenges facing the industry. More than half of consumers do not trust seafood, with one in five of all fish sold mislabelled. Read an overview of recent coverage on sustainable aquaculture from the World Ocean Initiative.
