Workshop (2h): Which design and support for robust transitions towards ecological horticulture?

Convener: Penvern S.

Wednesday 10th

Field visits (2 parallel trips)


Visit 1: Horticultural Agroforestry Systems (Lower Rhone valley). Experimental stations and organic vegetable farms

The trip will start with the visit of a tomato collection trial  at INRA- Genetics and Breeding of Fruit and Vegetables research unit. The trial is part of a European project « Traditom » on traditional tomato cultivars. It will continue at the GRAB. The GRAB is a non-for-profit research organization dedicated to organic farming, for fruits, vegetables and vineyard sectors. The 15-people staff carries out on-farm research in farmers plots directly, and spreads information and results at national and EU scale. See for more information.
On GRAB's experimental farm, you will be able to see various experiments dealing with agroforestry (mixing fruits and vegetables), functional biodiversity, behavioural assessment of cultivars for organic farming, adaptation to climate change, alternative methods for pest control...


Visit 2: Orchard'in: the Inra experimental station of Gotheron (Middle Rhone valley) and organic fruit farms

We will move Northwards to the middle Rhone valley in the Drôme department. The visits will start with the INRA experimental station of Gotheron where organic and IP orchards are experimented in apple and peach fruit production. The station of Gotheron develops research programs to design and manage orchards towards more sustainability; system experiments combining various levers to manage pests and diseases will be presented by the programs’ leaders in peach and apple. After lunch, two fruit farms in Loriol will be visited to highlight the diversity of production and marketing systems and exchange with growers.
