Colin Tudge is a biologist by education and a writer by profession, with published books on evolution, genetics, phylogeny, trees and birds. He also has a lifetime’s interest in food and agriculture, and in particular in the technologies and economic and social structures that are needed to feed everyone forever without wrecking the rest of the world. This was first outlined in his first book, The Famine Business, in the mid 1970s. In So Shall We Reap, in 2003, he invoked the phrase “Enlightened Agriculture” and developed this further in Feeding People is Easy. In 2009 together with his wife, Ruth, he founded the Campaign for Real Farming which led to the College for Enlightened Agriculture.
