Twenty years have passed. There’s plenty of food to go round, and it hasn’t cost the earth to produce… So what’s changed? Andrew Purvis has a crystal ball.

What will the food and drink industry look like in 2032? If world leaders, policy-makers and the private sector make the right commitments, the world will be better fed, the planet won’t be toast and there will be no unsustainable products on shelves. A whole host of initiatives – some by business, some by government – will have combined to get us there.

Every company will have a route map to sustainability, including a set of well-informed targets developed with scientists and stakeholders. Progress against these will be reported transparently, to make sure pledges are met. By 2032, all board directors will be remunerated on the basis of sustainability and rewarded for meeting these targets (as they are at Marks & Spencer and Unilever now). Enlightened companies will have abandoned quarterly reporting to shareholders, instead informing them about more solid, longer term prospects.
