"These projections of per-capita water availability were made by Martina Floerke and colleagues at the University of Kassel in Germany.

They combined different types of forecast to obtain their results. A computer model of climate change developed by the UK Met Office Hadley Centre generates projections of how temperatures and rainfall are likely to change in the future.

The Kassel team applied Hadley projections on a finer geographical scale. These projections were fed into a program that models water flow in river basins.

The Intergovernmental Panel on Climate Change (IPCC) produces 'scenarios' suggesting how society may develop economically and socially over time."
