Abstract. The uneven spatial distribution of basic facilities within urban areas is a major problem for developing countries like Senegal due to the emphasis of accessibility disparities and the use of this services. The efforts to quantify the problem and its consequences on people are constrained by the lack of satisfactory data and methods. The study seeks to examine the spatial accessibility to basic services (access to water, health, education, economic infrastructure and transportation services) in a very heterogeneous urban system and to highlight inequalities in access for improving the geographical accessibility and to ensure equity. The article explore the use of spatial analysis method (Closest Facility) to measure the potential accessibility to services and facilities in the city of Mbour. The analyses uses all the inhabited houses of the city as the potential demand. Results emphasis unequal access to basic urban services in the city and a center-periphery model with a high concentration of services around the city. The study demonstrates the utility of this method for the identification of disadvantaged areas, decision making and planning of basic services. It also provides paths for improving accessibility in urban areas with a high density of population.
Citizen and policy groups address environmental challenges in the Sahel, but rarely together. In Sahelian West Africa, including in Mauritania, Senegal, and Mali, artists and citizens have used protest art to make their voices heard, in contexts where this can carry risks of conflict with authorities. Artists sometimes act as engaged citizens, who can draw on their artistic talents to communicate a message. This paper explores how far art may be used as a tool for dialogue between different groups on environmental concerns in the Western Sahel.
L’art a été utilisé pour communiquer les préoccupations environnementales dans les pays sahéliens. Néanmoins, le dialogue dirigé par les arts entre les acteurs politiques et les citoyens est cependant rare, bien qu’il ait le potentiel de trouver des solutions aux problèmes socio-environnementaux complexes. Il est indispensable d’exploiter ce potentiel, alors que des défis, tels que le changement climatique, s’accélèrent et touchent les populations. La sensibilisation aux processus de dialogue menés par les arts pourrait être renforcée, parallèlement à davantage de recherches sur les contextes dans lesquelles ils sont appropriés et sur la meilleure façon de les utiliser.
