In this post in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, Eloise Quintanilla, an associate communications officer with the foundation, discusses an article published in the Guardian over the weekend that examines 15 simple innovations being used to tackle Africa’s health and development problems. She details three of the innovations included in the Guardian piece and writes that the article “serves as an excellent reminder that innovation doesn’t have to be technologically complex in order to be transformative” (8/28).
