THE IMPACTS OF CHANGE ON THE LONG-TERM FUTURE DEMAND FOR WATER SECTOR INFRASTRUCTURE Endnote Profile: Past Trends in Selected Countries Mexico Agriculture accounts for over 80% of water abstraction and 66% of total groundwater use. Groundwater also supports 70% of domestic and industrial water needs (Saleth and Dinar, 1999). By 1996 nearly 50% of the total public irrigation system had been transferred to water user associations. In the urban sector there have been reforms aimed at decentralising urban water supply away from central government to state and municipal governments and encouraging private investment. Central government retains responsibility for regulation, monitoring and enforcement, thus separating the management of resource issues from use and distribution. Urban access to drinking water was estimated at 96% in 2000, compared with 69% in rural areas (WHO, 2001); sewage and sanitation services had much lower coverage rates. Improvements in coverage between 1995 and 2000 were due to a national water pr
