Brief summary: The JArDinS study is a quasi-experimental research that aimed at assessing the impact of community garden participation (a natural experiment) in the adoption of more sustainable lifestyles.

Detailed description: The JArDinS study is part of the SURFOOD-Foodscapes project evaluating the relationships between urban foodscape and food styles in Montpellier Metropole (France).

JArDinS consists of a pretest-posttest quasi-experimental research and includes an experimental group of new gardeners starting gardening in a community garden in Montpellier and a control group comprising participants from a survey on food behaviors undertaken as part of SURFOOD-Foodscapes project. Participants will be surveyed at enrollment and 12 months later.

* age above 18 years
* ability to read in French and live in the city of Montpellier.

Exclusion Criteria:

* past experience of at least one household member in community gardening
* never doing grocery shopping for home
