- Goals: Increased water security, restoring depleted aquifers, counteract subsidence, counteract coastal saline intrusion, increased water supply.
- Solutions: Managed aquifer recharge (MAR), aquifer storage and recovery (ASR).
- Green infrastructure: Natural infiltration, revegetation, conservation agriculture.
- Grey infrastructure: Water retention/infiltration basins, runoff harvesting, in-channel mechanisms, recharge wells, riverbank filtration.
- Policy interventions: MAR policies, protection of recharge zones, managing groundwater discharge, land use regulations, managing groundwater use/entitlements, groundwater markets/payments for ecosystem services (PES).
