Farming is one of mankind’s oldest endeavors, and digital technology is one of its newest. The contributors to this fascinating volume bring them together, showing just how much good can come from the collaboration. By thinking in terms not just of crops or yields or prices, but rather of an integrated food system that links all players in the agricultural economy, Kofi Annan, Sam Dryden, and their fellow contributors allow us to see African agricultural issues in a new light. From mobile phones to big data, nutrition to climate change, the collection covers it all, with authors who have something powerful to say and the authority to be heard. They deserve kudos for their efforts in putting it together.
