Changes of groundwater conditions on Jeju volcanic island, Korea: implications for sustainable agriculture

A significant decline in groundwater levels and rise in electrical conductivity on Jeju Volcanic Island, Korea, indicates worsening seawater intrusion and groundwater quality deterioration. Despite efforts like banning illegal wells and artificial recharge using rainwater, groundwater use has surged from 110 to 195 million cubic meters annually (1999–2008), driven by agricultural, domestic, and industrial demands, as well as the growing adoption of ground source heat pumps. Long-term monitoring data reveals critical threats to sustainable water management on this streamless island.
