Urban sprawl development and flooding at Yeumbeul suburb (Dakar-Senegal)
Rapid development of urban centers in Africa is becoming a serious challenge for the coming decades with a wide range of foreseen social, economical and environmental implications. With the natural growth of the population, urban demography has been boosted by rural exodus triggered by serious droughts and increasing rural poverty. With the small resources available for an adequate urban management and the lack of efficient urban policy, Dakar capital of Senegal is characterized by an out of control urbanization process. Among the many impacts noted, flooding has appeared recently as a major threat for poor population leaving in the suburbs of Dakar. This study carried out at the outskirts of the town, in Yeumbeul District (17°24’ North, 14°46’ West), tries from rainfall variability, Digital Terrain Model and land cover change analysis since 1954 to track the interactions between natural and human causes of flooding occurring regularly since 1989. This integrated approach shows that the flooding process is not a mere climate variability related issue, it is tightly bound with poor urban management and occupation of irregular, unsuited land devoted to natural process. Satisfaction of housing needs was, for most poor rural dwellers, only possible through informal land markets, forcing them to settle in cheap yet risky lands. The recent extreme rainfall events reveal that most of these urban sprawls are located in flood prone areas. Environmental impacts of these flooded settlements have been examined. Serious flooding of 2005 has been a great momentum for the State and several other stakeholders to initiate various strategies that are discussed in this paper.Key words: Flooding, rural migration, irregular settlements, Dakar, Senegal

New approaches, new activities and new outcomes in international conferences on HIV/AIDS in Africa - report of the 3rd African Conference on the Social Aspects of HIV/AIDS, Dakar, 10-14 October 2005
Africa's HIV/AIDS situation remains cause for concern.The impact of HIV is considerable and threatens the survival and development of African societies.Although much has been attempted, the results still leave much to be desired. AIDS is an epidemic that needs to be addressed with much creativity and spirit of initiative. It is against this background that the 3rd African conference on the social aspects of HIV/AIDS brought innovations in the way international conferences are designed, activities implemented and results obtained. The innovations concerned the approach to international conferences and take into account reconceptualising HIV/AIDS so as to encourage holistic approaches and better visibility of vulnerable groups.The activities of the
conference were organised in such a way as to get people living with HIV/AIDS (PLWHA), grassroots communities and marginalised groups to play a focal role.The conference offered an opportunity for developing cultural activities that would translate the African cultural concepts that had been identified as important in the HIV situation and response analysis. Interaction at the conference created an opportunity to analyse the various dimensions of the political, cultural and economic determinants.
The conference offered food for thought around response construction while singling out the themes of urgency and acceleration of response, synergy construction, and coordination and conception of political responses.
