A field with a permaculture mandala garden, a project of the boarding private school Le Rosey, is pictured in Rolle, Switzerland, Sunday, May 24, 2020. The aim of the project is to create an open-air classroom to understand the life cycle of permaculture and to strengthen the school's organic and local supply chain. Preparations began last february on the one-hectare agricultural plot. One of the objectives is to produce more than 40 different kinds of organic fruit and vegetables for consumption in the boarding school. (KEYSTONE/Laurent Gillieron)
