World aquifer map unveiled

World aquifer map unveiled
The first-ever map of the world's underground water supplies has been unveiled by the United Nations Education, Scientific and Cultural Organisation (Unesco).

Drawing on data compiled since 2000, the map charts the world's underground aquifers – where 96 per cent of global freshwater resources are stored.

The map reveals that 273 aquifers cross national boundaries and 90 of those are in western Europe, though the UK does not share aquifers with other nations.

Unesco is publishing the map as part of its submission on a convention on aquifers that cross boundaries.

While the map suggests that other areas will face bigger water problems than the UK, the countries aquifers do not have the fastest rate of replenishment.

The map details areas where groundwater is saline, a problem which could affect more aquifers as climate change causes sea levels to rise.

A government report two years ago also suggested that Britain's water supplies, health, ecosystem, planning system and tourist industry would be affected by climate change, the Independent reported.

The western states in the U.S. have been having water wars for years. Calif., Arizona, Utah, and Nevada are fighting over water supplies that are much insufficient for growth needs in those areas.
But even the midwest (Ogallawa aquifer) and Florida are beginning to see water wars, with plans for moving water from some regions that have supplies insufficient for their growth and increasing salt water intrusion in coastal areas such as Florida.   There is a major water war between Florida, Alabama, and Georgia over water in rivers flowing between those states.
