The long-term effects of widespread greening on regional water cycling and deep water resources remain debated. The associated increase in ecosystem carbon gain and its impact on water consumption are unclear.

How and to what extent hydraulic redistribution may increase vegetation resistance to longer or more severe droughts than seasonal dryness have not been investigated yet, which is the focus of this study.

However, whether the associated increase in ecosystem carbon gain was accompanied by a proportional increase in water consumption and whether groundwater storage changed synchronously remain unclear.

Further research is needed to understand the long-term effects of ecological restoration on groundwater storage and ecosystem water cycling, - Studies should investigate the impacts of ecological restoration on localized or seasonal increases in transpiration, canopy interception, and root water uptake, - Research should focus on the indirect influences of vegetation change on infiltration, groundwater recharge, and subsurface flow
