How can we collectively ensure we are not forgetting the imminent environmental threats to our wellbeing? How can we brainstorm solutions these varied threats together, and find ways to forge a more sustainable world? One option: enter the Climathon, a global event where citizens gather and innovate together for a better future.

The 2020 edition took place online this month, and featured participation of cities across Europe and beyond, including ICLEI Members Berlin, Dresden and Mannheim (Germany), and Ljubljana (Slovenia).

The City of Turin (Italy) is working alongside ICLEI Europe as part of the proGIreg project, which aims to use nature for urban regeneration with and for citizens. As part of Climathon 2020, the city and its Environment Park challenged citizens to envision a regeneration scheme for an unutilised area in the city called ‘ex Combi’. Over 70 participants in 13 teams took part in the competition, which included online activities ranging from yoga to a cooking competition.

The winning project, aptly titled ‘Green Turin’ by the team ‘Sunny People’, sets out a holistic plan to create a sustainable future for the area. The entrance avenue would be transformed into a welcoming green corridor, bordered by trees and paved by tiles capable of converting the mechanical energy of walking into electricity to light the path. Green roofs would be implemented to contribute to improve the microclimatic conditions and help absorb pollutants. Urban gardens would be created and managed by students and neighbourhood associations, with the produce sold at a bistro on site. Last but not least, canopies with climbing plants would surround the area providing shade and respite. To make this green dream a reality, Green Turin will receive implementation support from Torino University and Polytechnic. The winners will also be treated to a urban horticulture course with proGIreg partner Orti Generali Foundation.

This is one example of how the Climathon offers an opportunity to rethink city spaces with nature-based solutions, by combining technical expertise with creative energy and environmental awareness.
