Analysis of the dynamics of two distinct land regimes in Senegal Case of the city of Touba and Ziguinchor (Senegal)

Context and background The originality of the urban structure of Touba lies first of all in its management led by the general Khalif and its particular status of a land title which is backed by a strong uncontrolled demography combined with a strong sprawl poorly controlled. Touba's town planning policy seems to boil down to the creation of housing plots and the free choice left to the caliph for the sites for installing equipment or infrastructure, and the destination of the reserves. On the other hand, in Ziguinchor, land dynamics have become a central problem. Today, the peripheral districts, "old" areas of culture (Kandialang, Kenya, Djibock, Lyndiane and Diabir) constitute the main destinations for new arrivals (both from the city and from the depths countryside) in search of habitat plots. Goal and Objectives: The objective of this article is to show the different territorial dynamics in urban spaces with different tenure and land practices. Methodology: The methodological approach is based on the one hand on a documentary review, observation, socio-demographic surveys, and interviews. On the other hand, the use of geomatics (openstreetmap, google earth and Quantum GIS software) will be used for mapping. Results: The advantage of this approach has allowed us to characterize the land regimes of Touba and Ziguinchor, to quantify the dynamics of the two distinct land regimes, and to identify the issues and consequences of these territorial recompositions.
