The last publication includes the presentation Water & Sanitation for Developing Clean and Healthy Cities by Dr Graham Alabaster of UN-Habitat, in which he presented the Lake Victoria sampling data for water supply in Kenya as an example to show that statistics on access to water coverage change significantly when quantity, cost and burden of collection are considered. (Monitoring that only looks at the type of water source can mislead policy makers who rely on these statistics.) The extreme case here is the town of Kisii where 71 percent of the population had access to an “improved” water supply in 2006, but only 2 percent had access to an “adequate” water supply (defined as >20 litres of water per person per day, <10 percent of household income spent on water, and <1 hour per household per day spent collecting water) (see blog of 14 January).
