Forecast of global water demand
1) Based on historical agricultural yield growth rates from 1990–2004 from FAOSTAT. Agricultural and industrial efficiency improvements from IFPRI.
2) Total increased capture of raw water through infrastructure buildout. Excluding unsustainable extraction.
3) Supply shown at 90 % reliability and includes infrastructure investments scheduled and funded through 2010. Current 90 % — reliable supply does not meet average demand.
