This booklet is a wake-up call about the situation in which more than half the world’s population is now living. For those living in the cities, it becomes increasingly more difficult to think about what lies behind a chicken, or a pineapple, which are purchased in large retail chains like Carrefour or Mercadona.  Meanwhile some 3 billion persons continue to produce almost all the food they consume, and they are effectively feeding 70% of the world population.
