At SIPEMA, the Coopérative des maraîchers de Saint-Omer, Paul Bailly is a bit at home. It has to be said that he spent 34 years of his life there, up to the position of director. So he’s no stranger to marsh vegetables! A living memory of the evolution of market gardening, he lived through the creation of the first sales dial, which freed up the cauliflower trade in the 70s, as well as mechanization, land consolidation, the increase in plot size and the decline in the number of market gardeners. “From 300 in the 70s to around 30 today”, he points out.
