Groundwater fate and climate change Simon Fraser University earth scientist Diana Allen, a co-author on a new paper about climate changes' impacts on the world's ground water, says climate change may be exacerbating many countries' experience of water stress.

"Increasing food requirements to feed our current world's growing population and prolonged droughts in many regions of the world are already increasing dependence on groundwater for agriculture," says Allen. "Climate-change-related stresses on fresh surface water, such as glacier-fed rivers, will likely exacerbate that situation. "

Add to that our mismanagement and inadequate monitoring of groundwater usage and we may see significant groundwater depletion and contamination that will seriously compromise much of the world's agriculturally-grown food supply." In "Ground Water and Climate Change," Allen and several other international scientists explain how several human-driven factors, if not rectified, will combine with climate change to significantly reduce useable groundwater availability for agriculture globally.

The paper was published in late 2012 in the journal Nature Climate Change. The authors note that inadequate groundwater supply records and mathematical models for predicting climate change and associated sea-level-rise make it impossible to forecast groundwater's long-range fate globally....
