On December 3rd, Hortis and AITF organise a thematical day with technical visits, conferences and a visit to the show allowing to exchange and understand better the problems relating to green space developments.

From the outset and the first edition of Paysalia, Greater Lyon has sponsored the event. It is important for us to be present because the public authorities we represent play an active part in the landscaping sector. The organization of the show includes visits to share our innovative projects in the Urban area to other public Theme days.

Participative Public Space Design in Tatarstan, Russia.
The Public Spaces Development Program was initiated in 2015 under the President of Tatarstan to develop and regenerate the parks, squares, riverfronts and pedestrian streets of the Republic. It is implemented in each of the 45 municipal districts, in settlements ranging from major cities to rural villages, and from the cultural and political capital to industrial centers, and to date, over 300 public spaces have been created or remodeled for year-round enjoyment. The program is hallmarked by a participatory process that engages with citizens and with the specific identity of the place and its communities, including infrastructure and programs for cultural activities to improve the attractiveness and the quality of life

Place de Francfort (3rd arrondissement of Lyon)

The Part-Dieu district involves an ambitious renovation and urban development project. This project integrates the requalification of over 30 ha of public spaces based on 3 principles:

  • Create an "easy ground" to facilitate movements
  • Reconstitute a "canopy" to fight urban heat islands
  • Prioritise the alternative management of rain water linked to a fertile sub-soil

The Place de Francfort (2018) meets these objectives – with an innovation! 93 trees planted in a continuous fertile subsoil to green a very mineral (granite pavement) yet completely permeable (draining joints between the flagstones) place. The experimental system is a load-bearing surface which retains and infiltrates rain water, creating a fertile, aerated and watered soil. A first in France on this scale.

Le Champ - Experiments at the "Station Mue" (2nd arrondissement of Lyon)

The Confluence district of Lyon is one of the major urban development operations in the Métropole. Started nearly 20 years ago and covering over 150 ha, this district reflects Lyon's ambition to be a sustainable City and includes a high density of landscaped spaces.


How do you return a polluted, sterile, former industrial site to nature without plundering the soils of agricultural and natural spaces in suburban areas?
The Mue station site tests the recomposition of the fertile substrate using a material recycling and circular economy logic system.
