TLDR
In this article, the authors performed a global-scale analysis of the impact of water withdrawals on water storage variations, using the global water resources and use model WaterGAP, and concluded that water withdrawals at the scale of the whole Mississippi basin cannot be monitored by GRACE.About:

TL;DR: In this paper, the authors critically review recent research assessing the impacts of climate on ground water through natural and human-induced processes as well as through groundwater-driven feedbacks on the climate system, and highlight the possible opportunities and challenges of using and sustaining groundwater resources in climate adaptation strategies.

TL;DR: It is shown that climate change is likely to exacerbate regional and global water scarcity considerably and GHM uncertainty is particularly dominant in many regions affected by declining water resources, suggesting a high potential for improved water resource projections through hydrological model development.

Lost food, wasted resources: global food supply chain losses and their impacts on freshwater, cropland, and fertiliser use
TL;DR: If the lowest loss and waste percentages achieved in any region in each step of the FSC could be reached globally, food supply losses could be halved and there would be enough food for approximately one billion extra people.

Regional strategies for the accelerating global problem of groundwater depletion
TL;DR: In this paper, a review of our understanding of groundwater depletion suggests that although the problem is global, solutions must be adapted to specific regional requirements at the aquifer scale, and that the world's largest freshwater resource is groundwater.

Global-scale assessment of groundwater depletion and related groundwater abstractions: Combining hydrological modeling with information from well observations and GRACE satellites
TL;DR: In this article, a new version of the global hydrological model WaterGAP was applied to derive groundwater depletion at the grid cell, country, and global levels, which simulates not only net groundwater abstractions and groundwater recharge from soils, but also surface water recharge from surface water bodies in dry regions.

An improved method of constructing a database of monthly climate observations and associated high-resolution grids
Timothy D. Mitchell,Philip Jones +1 more
TL;DR: In this paper, a database of monthly climate observations from meteorological stations is constructed and checked for inhomogeneities in the station records using an automated method that refines previous methods by using incomplete and partially overlapping records and by detecting inhomalities with opposite signs in different seasons.

Satellite-based estimates of groundwater depletion in India
Matthew Rodell,Isabella Velicogna,Isabella Velicogna,Isabella Velicogna,James S. Famiglietti +4 more
TL;DR: The available evidence suggests that unsustainable consumption of groundwater for irrigation and other anthropogenic uses is likely to be the cause of groundwater depletion in northwest India and the consequences for the 114,000,000 residents of the region may include a reduction of agricultural output and shortages of potable water, leading to extensive socioeconomic stresses.

Development and validation of a global database of lakes, reservoirs and wetlands
TL;DR: The Global Lakes and Wetlands Database (GLWD) as mentioned in this paper was created by combining the best available sources for lakes and wetlands on a global scale and the application of Geographic Information System (GIS) functionality enabled the generation of a database which focuses in three coordinated levels on (1) large lakes and reservoirs, (2) smaller water bodies, and (3) wetlands.

Groundwater use for irrigation - a global inventory
Stefan Siebert,Jacob J. Burke,Jean-Marc Faures,Karen Frenken,Jippe Hoogeveen,Petra Döll,Felix T. Portmann +6 more
TL;DR: In this article, the authors present a new global inventory on the extent of areas irrigated with groundwater, surface water or non-conventional sources, and determine the related consumptive water uses.

TL;DR: In this paper, the authors provided a global overview of groundwater depletion by assessing groundwater recharge with a global hydrological model and subtracting estimates of groundwater abstraction, and they estimated the total global groundwater depletion to have increased from 126 (±32) km3 a−1 in 1960 to 283 (±40) km 3 a −1 in 2000.
