This book shows how agriculture can help prisoners and ex-prisoners reintegrate into society, especially in Africa, explaining that African prisons are overcrowded and inhumane, while agriculture lacks skilled workers. Working the land helps psychologically, restores self-confidence, teaches patience, creates a sense of usefulness and builds a new, positive identity. The author proposes a concrete plan for the two years after release from prison to use 50% of the money to support people (psychologist, social aid, training), 25% to give them the means to get started (land, tools, seeds, start-up money) and 25% to help them progress (advanced training, entry into agricultural cooperatives). The book also proposes an international law creating a Global Program with a Financing Fund, recognized training and fair wages. To succeed, participation must be voluntary, training must be serious, support must last a long time, ex-prisoners must have access to land and society must stop rejecting them.
