While there are obviously strong ethical reasons to focus on supporting a more sustainable food environment in developing countries, it also makes sense from a business point of view, as companies increasingly see the opportunities that sustainability can bring.
"If people can't afford food in those countries, then their branding and their initiatives are for naught," Nierenburg said.
However, although many companies are aiming to play a stronger food security and sustainability role, she added that it is important to recognise that some are engaged in greenwashing.
"I think there needs to be a balance between the power that the food industry really does have and (...) making sure that they are really living up to their promises."
