Feeding the world has always been a challenge - but doing it amid a changing climate is only going to get more difficult. The UN's Food and Agriculture Organisation estimates we'll need to produce 70 percent more food by 2050 to feed the world's population of 10 billion. ZeaKal is a biotech company with roots in New Zealand and California which has been working on how to increase crop yields without sacrificing nutrition, while also creating a smaller environmental footprint. Its PhotoSeed technology modifies gene traits to increase a plant's ability to capture carbon and light. This in turn, boosts yield, nutrient density and also increases carbon capture. Han Chen is the CEO of ZeaKal and joins Kathryn to explain more. He'll also be speaking as part of E Tipu, the Boma Agri Summit taking place next month.
