International audience ; Studies on urban spaces require detailed information with a high quality. This has a cost that limits its availability in the less developed countries and makes researchers dependent on existing resources. Whatever the considered problem, the question of sources is essential. With the development and democratization of GIS and satellite imagery, a large number of information from increasingly diversified sources becomes available. The civilian satellites to Earth observation flying over the planet for the years 1960-70, enable the detection and mapping of different ecosystems. In this study, we plan to explore the Dakar metropolitan area. Big African metropolis Dakar has a good-quality census coverage, which has recently been spatialized. We also have recent satellite images complementing this equipment. If a study on the crossing of census data with satellite information is not a very original approach, its application to the metropolitan Dakar will investigate specifically the sub-space urban areas of the city. Interest will therefore to establish links between social attributes (by census data), landscapes in these areas, and their occupation of the land (environmental variables extracted from satellite imagery). These preliminary results, presented here, will be the cornerstone of a study of urban malaria, which questions the interactions between the space of the vector, Anopheles, and that of the host, the human being. However, the spatial distribution of the vector is closely related to socio-economic attributes of populations. In other words, we wish initially to assess the relevance of these two sources in order to approach the wealth inequalities of the population of Dakar. This concept is defined synthetically by the lack of material resources of the inhabitants, which places them in a precarious and unstable situation when they are subjected to an external threat (eg floods, diseases, .) This work will also inform the geography of the city of Dakar, at a fine scale or even ...

The plight of refugees has become a global social problem due to continuous political unrest, war and natural disasters worldwide. People are forced to migrate to other countries for safety and better living conditions in the hope that their basic human rights will be upheld. However, many destinations chosen by refugees face social problems of their own and are failing to provide basic services to citizens leaving the onus of service provision on charitable or Non-Profit Organisations (NPOs). South Africa is no exception as it has become a popular destination for refugees from other African countries and Asia but is not able to adequately provide for their needs. In this situation, NPOs have taken a central role in ensuring refugees are integrated into the South Africa society. This exploratory research examined the experiences of refugees accessing services from NPOs in Cape Town. A qualitative design and purposeful sampling are used to delve deeper into the experiences of refugees to amplify their voices about service provision. Refugees from six different NPOs in Cape Town namely: Adonis Musati Project, Triangle Project, PASSOP, MRASA, VIDEFI and Kwesu Women's organisation were interviewed about their experiences of accessing services. Participants had to be recipients of one or more of the services from any of the NPOs chosen for the research study. Their experiences related to the benefits and challenges faced when accessing services from NPOs and negotiating and navigating the challenges faced in accessing services from NPOs. The study revealed that refugees benefit from services offered to them although the challenges outweigh the benefits due to lack of funding and failure to provide adequate resources. The refugees mainly needed services to help them secure employment, documentation, and access to healthcare and basic education. They needed referrals to access these services from other NPOs or government institutions otherwise it was difficult to obtain. The refugees shared their experiences and on this basis recommendations on improving the services needed to ensure basic human rights are included in this study.
