Agricultural managed aquifer recharge (Ag-MAR)—a method for sustainable groundwater management: A review

open access: yesCritical reviews in environmental science and technology, 2022
More than two billion people and 40% of global agricultural production depend upon unsustainable groundwater extraction. Managed aquifer recharge (MAR), the practice of strategically recharging water to replenish subsurface storage, is an important ...

Delineating Groundwater Recharge Potential through Remote Sensing and Geographical Information Systems

open access: yesWater, 2022
Owing to the extensive global dependency on groundwater and associated increasing water demand, the global groundwater level is declining rapidly. In the case of Islamabad, Pakistan, the groundwater level has lowered five times over the past five years ...

Global Recharge Data Set Indicates Strengthened Groundwater Connection to Surface Fluxes

open access: yesGeophysical Research Letters, 2022
Groundwater is an invaluable global resource, but its long‐term viability as a resource for consumption, agriculture, and ecosystems depends on precipitation recharging aquifers.

Evaluation of drought impact on groundwater recharge rate using SWAT and Hydrus models on an agricultural island in western Japan [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
Clarifying the variations of groundwater recharge response to a changing non-stationary hydrological process is important for efficiently managing groundwater resources, particularly in regions with limited precipitation that face the risk of water ...

Mapping groundwater recharge in Africa from ground observations and implications for water security

open access: yesEnvironmental Research Letters, 2021
Groundwater forms the basis of water supplies across much of Africa and its development is rising as demand for secure water increases. Recharge rates are a key component for assessing groundwater development potential, but have not been mapped across ...

Groundwater and baseflow drought responses to synthetic recharge stress tests [PDF]

open access: yesHydrology and Earth System Sciences, 2021
Groundwater is the main source of freshwater and maintains streamflow during drought. Potential future groundwater and baseflow drought hazards depend on the systems' sensitivity to altered recharge conditions.

Evaluating Groundwater Storage Change and Recharge Using GRACE Data: A Case Study of Aquifers in Niger, West Africa

open access: yesRemote Sensing, 2022
Accurately assessing groundwater storage changes in Niger is critical for long-term water resource management but is difficult due to sparse field data. We present a study of groundwater storage changes and recharge in Southern Niger, computed using data

Assessing the role of groundwater recharge from tanks in crystalline bedrock aquifers in Karnataka, India, using hydrochemical tracers

open access: yesJournal of Hydrology X, 2022
The majority of India’s rural drinking water supply is sourced from groundwater, which also plays a critical role in irrigated agriculture, supporting the livelihoods of millions of users. However, recent high abstractions are threatening the sustainable

Impacts of climate change on Swiss alluvial aquifers – A quantitative forecast focused on natural and artificial groundwater recharge by surface water infiltration

open access: yesJournal of Hydrology X, 2022
The sensitivity of future groundwater recharge and temperature development was investigated for three alluvial aquifers in the urban agglomeration of the city of Basel, Switzerland. For selected climate projections groundwater recharge and the associated
