Abstract:
The fundamental objective of this research is to provide a better understanding of what causes
insalubrity within the city of Cotonou.
The probabilist method and the random choice technique have been used in the selection of the
sample proportionally to the size of the structures based on some criteria. The samples size is
determined in accordance with Schwartz method. In order to identify the causes of insalubrity,
the parameters were introduced in the mini tab software to perform the simple regression
analysis. The Durbin-Watsons statistic, Ryan Joyner normality and Henri adjustment were used
to assess the significance of the model. The evaluation study of healthy places is conducted
through factors such as : rain water evacuation network, flood and coverage rate of pre-collection
in order to determine a healh card. The combination of the factors of safety of the spaces is
realized. It was calculated, the insalubrity rate (IS1) taking into account the effects of
anthropogenic factors (rain water evacuation network coverage rate of pre-collection and volume
of waste) on the salubrity.
