Bill Gates for a Day: Water & Sanitation
By Guy Hutton
In the year 2002, it was reported that 1.1 billion lacked access to improved drinking water sources and 2.6 billion lacked access to improved sanitation. In some less developed world regions, the proportion of the population lacking access to improved water supply and sanitation was disturbingly high, especially for improved sanitation access. In terms of overall numbers, more than 90% of the world’s population lacking access is living in Asia and Africa. In fact, around 70% of the 1.1 billion lacking access to improved drinking water sources and around 78% of the 2.6 billion lacking access to improved sanitation access are located in just 11 countries.
Unsafe and inaccessible water and sanitation is a human problem for many reasons, covering personal hygiene and dignity, disease risk, environmental impact, as well as overall developmental impact related to health status, time use and production decisions. Furthermore, coverage of improved water and sanitation is strongly related to household income and dwelling location, thus indicating severe inequalities in society such as between the rich and the poor, and between rural and urban populations.
