Agroforestry combines the planting of shrubs with agricultural crops. The objective is to promote biodiversity and protect the land.

In recent years, this type of land use combining trees and agricultural crops on the same plot has been redeveloping after decades of land consolidation. The meeting was set at a watercress patch in Cerny (Essonne) Abandoned for five years, it is being rehabilitated by Matthew Charlton, a 37-year-old Englishman who already grows organic water cress in D'Huison-Longueville.
