                   1.10 Groundwater resources in
                   developing countries

                   In the developing world, groundwater is extensively
                   used for drinking water supplies, especially in smaller
                   towns and rural areas, where it is the cheapest source.
                   Groundwater schemes consist typically of large num-
                   bers of boreholes, often drilled on an uncontrolled

                   unconnected supplies. Shallower dug wells continue

                   boreholes (100 L s ) are quite widely developed in
                   larger towns to provide piped supplies. Even in these
                   cases, raw water monitoring and treatment are   and local aquifer management. For the future, sus-
                   often limited and intermittent. An example of the  tainable livelihoods, food security and key ecological
                   significance of groundwater in leading the economic  systems will be dependent on such initiatives.
