After the commotion over the irrigation expansion plan next to the park, some large food chains follow in the wake of the European ones and require the strawberry farmers of Huelva to certify the legality of water for crops. Sustainability has spread in Spanish chains such as Eroski (4% market share), the French Carrefour (7%) and the German Lidl (6%) and Aldi (1.5%) The four are committed to the Spring seal or similar, although only Aldi guarantees that next winter all its strawberries will have this guarantee.
