This week Adah Parris is joined by two entrepreneurs using seemingly low-tech solutions to solve big global challenges. Wefarm founder and CEO Kenny Ewan explains how he’s built a groundbreaking peer-to-peer network for small scale farmers across the world, helping them share knowledge using the humble SMS text message. Plus, we meet Joanne Peter (Global Community Impact, Johnson & Johnson), who introduces Momconnect – a project in partnership with the South African Department of Health providing vital healthcare information to mothers.
