Enhancing citizen engagement to design, locate and build a green solution

The core activity of the project was to design a green or blue solution to mitigate the impact of climate change through design and to build a natural space to help to cool public spaces in Lyon. Place Saint-Jean was chosen as the experimentation site in Lyon, which is a UNESCO World Heritage Site. This means that nothing could be planted including on roofs and facades and no water features added. For this reason, we focused on a mobile garden that was built in the Lyon Pressin Horticultural School and then moved into the Place Saint-Jean. To be mobile meant that the garden must be the same size as a wooden pallet, which is a major constraint.

A strong and efficient mobilisation of the involved partners was managed according to the work plan, enabling indirect exchanges between citizens and high-school students to design and build the green solution in accordance with the expectations of citizens.

The main impact of the project for Lyon City is the fact, that the experimentations have been conducted in Lyon and the methodology deployed in this project could be replicated within the city of Lyon and in other cities too. Due to the seasonality of the project the monitoring campaign planned for spring, summer and the early autumn 2022 to assess the benefit of the green solution in terms of cooling. Two devices were implemented: one near the garden and one at the opposite side of the green solution, to witness the changes brought by the green solution. RESALLIENCE will then be able to quantify the difference of temperature and humidity between the two sites and the benefits in terms of cooling.
