Chapter 7: Food security & agriculture
Agriculture and livestock cover over one-third of the world’s land surface, dwarfing all other land uses. Intensification, driven by a lucrative but largely inefficient food system, has boosted production. However, it has also disturbed cultural landscapes, sustained over thousands of years, and accelerated land and soil degradation, water shortages, and pollution. In spite of production increases, we are now experiencing widespread food insecurity in what should be a world of plenty.
