“…The recharge of treated sewage, stormwater, and diverted surplus streamflow into aquifers for subsequent use by means of managed aquifer recharge constitutes an active effort to achieve sustainable groundwater use by means of managed aquifer recharge (Dillon et al 2019). Other options available to combat groundwater depletion are strategically managing the trade of virtual water (i.e., water consumed in the production of goods, Delpasand et al 2020Delpasand et al , 2022, expanding alternative water sources such as seawater desalination powered by renewable energy (see, e.g., Gao et al 2017) and protective of marine ecosystems (Sheibani et al 2023), modifying cropping patterns and dietary customs in favor of foods that have a lower water footprint (Kheirinejad et al 2022;Radmehr et al 2022), metering water use and pricing water at its marginal cost to reduce wasteful use (Kiparksy et al 2018;Maples et al 2018), and developing a shared groundwater platform for groundwater monitoring and prediction (Condon et al 2021).…”

The intensity of global groundwater use rose from 124 m3 per capita in 1950 to 152 m3 in 2021, for a 22.6% rise in the annual per capita use. This rise in global per capita water use reflects rising consumption patterns. The global use of groundwater, which provides between 21% and 30% of the total freshwater annual consumption, will continue to expand due to the sustained population growth projected through most of the 21st century and the important role that groundwater plays in the water‐food‐energy nexus. The rise in groundwater use, on the other hand, has inflicted adverse impacts in many aquifers, such as land subsidence, sea water intrusion, stream depletion, and deterioration of groundwater‐dependent ecosystems, groundwater‐quality degradation, and aridification. This paper projects global groundwater use between 2025 and 2050. The projected global annual groundwater withdrawal in 2050 is 1535 km3 (1 km3 = 109 m3 = 810,713 acre‐feet). The projected global groundwater depletion, that is, the excess of withdrawal over recharge, in 2050 equals 887 km3, which is about 61% larger than in 2021. This projection signals probable exacerbation of adverse groundwater‐withdrawal impacts, which are worsened by climatic trends and the environmental requirement of groundwater flow unless concerted national and international efforts achieve groundwater sustainability.

Climate change and the increase of population pose challenges to ensuring suitable water supply in water-scarce regions. This work presents a comparative analysis of the water-supply approaches adopted in Los Angeles, Southeastern Spain, and Sydney. Results show a decrease in per-capita water use in the period 2000–2020, which reflects an improvement in water conservation. Social factors in the domain of hydropolitics and economic efficiency explain the divergence of water policies adopted. The adaptation to water scarcity and growing population in three regions of developed countries located in different continents sheds light on challenges facing the achievement of water security worldwide.
