Jardin des partages

An agricultural and educational laboratory

A unique space within the Vallée de la Millière

In 2020, photographer and environmental activist Yann Arthus-Bertrand, a long-time partner of Guerlain on numerous projects, purchased an exceptional 30-hectare (74-acre) estate in Yvelines, France – the Vallée de la Millière – with the aim of creating a biodiversity reserve through rewilding.

A historic site
for the Guerlain family

Located on the edge of the Rambouillet forest, a historic site for the Guerlain family, this area is now home to over 350 animal and plant species.

Supported by LVMH, the Vallée de la Millière serves as a prime research site for scientists to reduce human impact on ecosystems, notably through its partnerships with the University of Paris Saclay and the Haute Vallée de Chevreuse Regional Natural Park.

Regenerative Agriculture
on 1.4 hectares

Within it, a 1.4-hectare (3.5-acre) area is dedicated to regenerative agriculture: the Jardin des Partages, supported by Guerlain. Designed as a living laboratory, a place for education and dialogue between nature and culture, this garden aims to reconcile abundant and diverse production with lush, ubiquitous biodiversity.

It embodies the values of our Maison: passing on knowledge and experimenting with virtuous practices alongside our partners.

Measure the environmental impact

In order to measure the environmental impact of the methods applied, Genesis conducts regular soil analyses, allowing key indicators (biodiversity, soil fertility, climate, water management) to be monitored and correlated with external factors (climate stressors, productivity, off-soil biodiversity, etc.).

The creation of a melliferous area

After three years dedicated to the garden’s creation according to agroforestry principles by Tom Arthus-Bertrand and his team, the next three years will focus on developing a melliferous area, creating an experimental market gardening plot and rolling out educational activities for the general public as well as Guerlain and LVMH employees.
