When your well runs dry Groundwater provides nearly half of the water used for agricultural irrigation and most of the drinking water for billions of people. It is essential, then, for this resource to remain secure. Jasechko and Perrone examined data from approximately 39 million wells in 40 countries worldwide to investigate their vulnerability to declining water levels (see the Perspective by Famiglietti and Ferguson). The authors found that construction of deeper wells is not occurring in… 

Revealing the importance of groundwater for potable private water supplies in Wales

At least 77,000 people across Wales rely on private water supplies for their drinking water, with 94 % of these supplies dependent on groundwater. Potable private water supplies were mapped to Lower

Domestic-well failure mitigation and costs in groundwater management planning: observations from recent groundwater sustainability plans in California, USA

Domestic supply wells meet much of the world’s potable water demand. These wells tend to fail as regional groundwater levels decline from intensive agricultural groundwater use, especially during

Global Assessment of Groundwater Stress Vis-à-Vis Sustainability of Irrigated Food Production

Due to poor water resources management, groundwater-dependent agriculture induces substantial stress on several aquifer systems worldwide, which poses a serious threat to water and food security.

Groundwater in Crisis? Addressing Groundwater Challenges in Michigan (USA) as a Template for the Great Lakes

Groundwater historically has been a critical but understudied, underfunded, and underappreciated natural resource, although recent challenges associated with both groundwater quantity and quality

Optimization of Groundwater Exploitation in an Irrigation Area in the Arid Upper Peacock River, NW China: Implications for Sustainable Agriculture and Ecology

Groundwater is the main irrigation water source in the Upper Peacock River. As fast enlargement of irrigation areas continues in recent years, the groundwater level declines continuously and has

The Importance of Prevention in Tackling Desertification: An Approach to Anticipate Risks of Degradation in Coastal Aquifers

Groundwater degradation is a major issue on an increasingly hot and thirsty planet. The problem is critical in drylands, where recharge rates are low and groundwater is the only reliable resource in

When the virtual water runs out: local and global responses to addressing unsustainable groundwater consumption

ABSTRACT Given the growing importance of groundwater in irrigated crop production, policies aimed at restricting groundwater use create fears of intensified food insecurity. Yet, a comprehensive



Dry groundwater wells in the western United States

Declining groundwater levels are common in parts of the western US, but their impact on the ability of wells to pump groundwater is not known. Here we collate groundwater well records for the western

Water balance of global aquifers revealed by groundwater footprint

The groundwater footprint is the first tool suitable for consistently evaluating the use, renewal and ecosystem requirements of groundwater at an aquifer scale and can be combined with the water footprint and virtual water calculations, and be used to assess the potential for increasing agricultural yields with renewable groundwater.

Deeper well drilling an unsustainable stopgap to groundwater depletion

Groundwater depletion is causing wells to run dry, affecting food production and domestic water access. Drilling deeper wells may stave off the drying up of wells—for those who can afford it and

Groundwater depletion: A global problem

In the past half-century, ready access to pumped wells has ushered in a worldwide “explosion” of groundwater development for municipal, industrial, and agricultural supplies. Globally, groundwater

Global Patterns of Groundwater Table Depth

Global observations of water table depth compiled from government archives and literature are presented to fill in data gaps and infer patterns and processes using a groundwater model forced by modern climate, terrain, and sea level.

A global dataset of surface water and groundwater salinity measurements from 1980–2019

A new global salinity database is presented, compiled from electrical conductivity monitoring data of both surface water and groundwater locations over the period 1980–2019, which comprises more than 16.3 million measurements from 45,103 surface water locations and 208,550 groundwater locations around the world.

Groundwater use for irrigation - a global inventory

Abstract. Irrigation is the most important water use sector accounting for about 70% of the global freshwater withdrawals and 90% of consumptive water uses. While the extent of irrigation and related

Global Groundwater Sustainability, Resources, and Systems in the Anthropocene

Groundwater is a crucial resource for current and future generations, but it is not being sustainably used in many parts of the world. The objective of this review is to provide a clear portrait of

Domestic well vulnerability to drought duration and unsustainable groundwater management in California’s Central Valley

Millions of Californians access drinking water via domestic wells, which are vulnerable to drought and unsustainable groundwater management. Groundwater overdraft and the possibility of longer
