Sanitation

The safe disposal of human excreta is a basic human need and one of the most important improvements any government can make towards improving public health. At present more than  2.6 billion people worldwide lack access to improved sanitation, of which most live in Asia and Sub-Saharan Africa. This situation in the twenty-first century is scandalous.

Lacking access to sanitation is associated with severe health risks. Diarrhoeal disease kills more than two million people every year. Most of these are children under the age of five. The burden of worm infections (intestinal helminths) causes anaemia and can stunt growth in children.

For millions of people lacking sanitation means not having any privacy or dignity. It puts women and girls in danger from sexual harassment and assault, especially after dark. It brings other social costs such as embarrassment when others visit and it brings economic costs from health care and lost earnings.

Sanitation is one of the Environmental Health Group’s major areas of focus and for us sanitation is more than just toilets. Our work looks at new technologies, re-use of wastewater, fecal sludge management, strategies for marketing sanitation, shared sanitation and child faeces disposal.
