Critical

WRI Aqueduct 4.0: Extremely High baseline water stress (4.2). Illegal and semi-legal irrigation wells documented exceeding sanctioned volumes. Strawberry and blueberry expansion accelerating demand in a region with critically low recharge.

Regulatory alignment

51-3

Critical

UNESCO World Heritage site under threat; EU infringement proceedings active. CSRD exposure high for berry-sourcing retailers.
