Nature is the first victim of the sharp rise in temperatures linked to global warming. The soils are thirsty, even at the water’s edge. Example in the marshes of Audomarois (Pas-de-Calais), in the middle of the cauliflower harvest.
On the plots of Alexandre Grave, the rain is slow. For lack of water, his cauliflowers do not grow. To cope with this onset of drought, the market gardener had to invest more than 40,000 euros in an irrigation system. A significant cost that it is not certain to amortize. “Normally, the cost of producing a cauliflower is between 65 and 70 cents. Here we will be close to 1 euro”, says the market gardener, who sells his cauliflowers for 30 cents in the height of summer.
Drought traditionally spares the crops of the Audomarois marsh, a vast expanse of land surrounded by canals. Here, the ground is constantly wet. However, Jérôme Moivre also had to start irrigating the land a month earlier than usual. If he remains confident for the future of his plantations, he still hopes to see the rain fall. Cabbage cultivation fears strong heat and wind, and above all has little resistance to excess water.
