Implication

Numerical modeling reveals significant groundwater depletion and seawater intrusion risks in Karachi's aquifers, indicating urgent need for recharge monitoring.

Key Points

Annual groundwater decline of 0.5–1.0 m linked to seawater intrusion in Karachi aquifers, threatening resources.
Groundwater levels projected to drop by 5.52 m by 2043 under status quo conditions, with substantial saline encroachment.
Scenario analysis using numerical modeling assessed potential future impacts of climatic variability and land use changes.
Management strategies focused on recharge and monitoring are essential to counter seawater intrusion risks.
