New study raises question: What don’t we know about water scarcity?
A new study from the United States Geological Survey (USGS) reveals troubling news: The aquifers that millions of Americans rely on for freshwater are being depleted at an accelerating rate. In fact, aquifer depletion in the years between 2004 and 2008 was nearly triple the historical average. Population growth and increasing demand—in particular for irrigating crops—are straining ...

Africa may struggle to extract groundwater, experts say
Vast groundwater resources have been revealed in Africa by the first continent-wide quantitative maps. But the resources may not be easily accessible because of political and technical challenges and costs, say experts. The new groundwater maps, published last month (19 April) in Environmental Research Letters, are based on an extensive review of available maps, publications and data. They show ...

New map of global groundwater depths
Despite groundwater’s importance to ecosystems, little is known about its global distribution. Researchers have now developed a model to map groundwater, revealing that ecosystems covering 22-32% of the Earth’s surface rely on this important resource. Groundwater is vital for many ecosystems, providing crucial support to plants and animals, especially during droughts. ...

Mapping groundwater flooding for the EU Floods Directive
In the coming years the EU Floods Directive1 will require Member States to produce flood hazard and risk maps. Taking the UK as a case study, new research highlights the need for advances in data collection, mapping and groundwater flood warning systems to meet EU requirements for maps and management plans. Although often occurring less frequently than fluvial (river) flooding, the effects of ...

Kenya homes in on emergency groundwater supplies
A project that will map groundwater resources in part of the drought-prone Horn of Africa region was launched in Nairobi, Kenya, last week (22 May). It will use remote sensing technology to explore underground water to establish its quantity and quality, with the aim of exploiting the water in an emergency to combat drought and famine, and also to develop long-term resilience. The project is an ...

New US Geological Survey information system reveals why Arizona’s groundwater levels are falling
Where in Arizona are groundwater levels falling? Where are they stable or rising? How much has the water table changed since large-scale pumping has occurred? A new online system developed by the U.S. Geological Survey (USGS) is designed to answer these and other questions for the most developed ground-water areas in the State. The system uses water-level measurements from wells, collected over ...
