The Four Keys

The Four Keys are four comprehensive books compiled by members of the Global Ecovillage Educators for a Sustainable Earth (GEESE), offering an overview of the state of the art of sustainable settlements globally. Each key covers one of the dimensions of the EDE curriculum: Economic, Worldview, Ecological and Social. They make ideal introductions to EDE, companions on the journey of an EDE course or reference books for anyone seeking solutions to the complex problems of climate change, peak oil and carbon reduction.
