Service Description:

Groundwater Depletion

Excessive groundwater pumping leads to declining aquifer levels, which threaten people, agriculture, and natural ecosystems, including the birds and wetlands that depend on these sources of water. Impacts to underground aquifers will grow where the climate becomes warmer and drier. By carefully managing groundwater levels with input from all affected communities, we can ensure that there is sufficient water for birds and people.

Processing

We mapped the current footprint of groundwater pumping as a binary surface by identifying 3-km cells where the maximum anthropogenic groundwater depletion between 2000 and 2010 exceeded 0.25 millimeters per year.
