Think back to Study Session 1 and explain what you understand by the sanitation ladder.

Show answer

The sanitation ladder measures progress towards providing adequate sanitation facilities for every household. It ranks sanitation provision in increasing order of desirability, as listed below:

  • open defecation (least desirable)
  • unimproved facilities
  • shared facilities
  • improved facilities (most desirable).

Figure 5.1 shows the changes in sanitation coverage in Ethiopia from 1990 to 2012 for urban and rural populations, and the total for the whole country. The columns in the diagram show the coverage according to the categories of the sanitation ladder. The sloping lines between 1990 and 2012 indicate the change over that time.

Open defecation leads to the spread of disease and environmental pollution, so even the basic latrine is an improvement. The following sections of this study session describe the different types of latrine that come above open defecation on the sanitation ladder.
