Consulting IGRAC´s GGMN at the Los Arenales aquifer
Part of the data used for a ‘global-scale’ study of groundwater levels, published in #Nature, is now available in our Global Groundwater Information System. The analysis is rooted in the analysis of millions of groundwater-level measurements in 170,000 wells from 1,693 aquifer systems in over 40 countries.

Successful human interventions
Jasechko et al. (2024) also highlight some successful human interventions addressing groundwater depletion. For example, in Bangkok (Thailand), groundwater-level declines of the 1980s and 1990s were reversed following the implementation of regulations designed to reduce groundwater pumping. Meanwhile, in Albuquerque, New Mexico (USA), groundwater levels are recovering after an inter-basin transfer of surface water alleviated groundwater demand. And finally, a managed aquifer recharge scheme in the Avra Valley of Arizona (USA) is replenishing a depleted aquifer using water that has been diverted from the Colorado River.

We have consulted the IGRAC site for Los Arenales aquifer, to check happily that the trends of the piezometers closest to the recharge areas are coming up for the groundwater level; but other piezometers nearby are still coming down.
