Published in the Acer magazine n. 2/19 of ‘Il Verde Editoriale’ an article on the differentiated management of lawns in public parks, to reduce management costs and improve biodiversity and their adaptability to climate change. The article collects some reflections on the cultural and aesthetic aspects related to the turf and highlights the need for a route change towards an ethically more sustainable management and protection of environmental resources. Finally, the results of some years of experimentation carried out in collaboration with UGRAA (Environmental and Agricultural Resources Management Office) are reported in some parks designed by the Pampa studio in the territory of the Republic of San Marino.
