Cartography of the segregation as a tool of decision-making aid for the fight against poverty: case of the town of Yaounde (Cameroon)

The urban demographic explosion in the developing countries (DC) is generally accompanied by segregative phenomenon for the populations with low income and exposes them to several types of risks. This phenomenon of segregation, object of this study, is the result of the containment of the poor city dwellers in zones which are difficult to arrange, and in which the risks are numerous. This paper proposes a method of identification of the segregations and their domains of appearance, the analysis of the explanatory factors and their evaluation, using suitable mathematical tools. An application to the case of the town of Yaounde is used as illustration with our study. We charted the socio-spatial segregation in the town of Yaounde and implemented the characteristic elements of cartography of segregation in a given environment. We defined also the existence of the threshold of segregation and the intensity of a segregation associated with a domain.
