Groundwater extraction for nawadniation in many agricultural regions excedes natural recharge rates, lowering water tables andd driing up streams that sustain aquatic life. Thi unsustainable use extraiens srecovater biodiversity and reduces water acceptibility for both ecosystems and human communies.
