The third edition of the Radicepura Garden Festival attempts to provide answers to such pressing issues starting from the urgent need for sustainable economic, environmental and social development, a paradigm that defines the Millennium Development Goals (MDGs) of the UN Agenda 2030. Increasingly in the international debate on the fight against climate change, green environments are recognised as precious and effective resources able to naturally lower air temperatures and contribute to improving their quality. Gardens have been acknowledged as being able to repair, i.e. protect and defend, the planet. Designing and creating the gardens of tomorrow means imagining the future of people and cities and it is with this objective that the Call for Ideas with the theme ‘GARDENS FOR THE FUTURE was launched in 2021. Seven young landscape architects from all over the world were selected among candidates, who created their own garden, offering their personal vision of the theme contextualised in the Radicepura Park. This triggered triggering an allround discussion under the landscape of director Antonio Perzzi, botanist and writer. An opportunity for the Radicepura Garden Festival to establish itself as a nursery for young talents.
