As frontier markets find themselves—and in some cases place themselves—at the heart of some of the most important challenges the planet and the world’s economies are facing, investors are seeing new opportunities that simply couldn't have existed just a few years ago. We meet up with pioneering frontier-markets investor Alison Graham of Voltan Capital Management to talk about digitizing supply chains, the management of waste, tackling climate change … and blockchain. Cutting edge stuff, indeed!
