abstract = "{Groundwater is essential for sustaining water supply security and
ecosystem stability in arid and semi-arid ecologically fragile
steppe areas, Northern China. However, the drivers of
groundwater storage changes in this steppe remain unclear, and
how climate change and human activities affect groundwater
storage and their relative contributions are not well
characterized because of the paucity of long-term observations.
A more comprehensive understanding of the drivers of groundwater
storage changes in large grassland areas and their quantitative
contributions is needed as we strive to combat grassland sanding
and protect groundwater resources. Here we leveraged NASA's
GRACE/FO satellite data to estimate nearly two decades
observations of groundwater storage and reveal significant
groundwater storage depletion (‑4.4 {\ensuremath{\pm}} 0.1
mm/yr; 0.89 {\ensuremath{\pm}} 0.02 km$^{3}$/yr, p < 0.05)
driven by intensive human activities and climate change in this
typical steppe areas of Northern China. We further integrated
the land surface model that assimilated GRACE/FO data (i.e.,
CLSM-DA) and machine learning to identify and quantify the
relative contributions of various drivers to groundwater storage
decline. The results indicate that water consumption due to coal
mining, groundwater withdrawals, and other human activities
significantly contributed to groundwater storage decline.
Remarkably, escalating human activities have a significant
impact on groundwater storage, accounting for nearly two-thirds
of groundwater storage decline (‑2.8 {\ensuremath{\pm}} 0.2
mm/yr, p < 0.05) over the past two decades. This study
emphasized the pronounced impact of increasing human activities
on groundwater storage decline, highlighting the urgency of
valuing and protecting groundwater resources to better support
ecological stability in ecologically fragile areas.}",
