City and sanitation in Africa in flood management: the case of Abidjan

The effects of climate change are numerous throughout the world with loss of life and property damage. In Africa and particularly Côte d’Ivoire these recent years have shown an increase in disasters caused by heavy rains. The floods have negative effects on people. In the case of floods they cause among other landslides and mudslides. Remote sensing and geographic information systems (GIS) are increasingly used to study surface phenomena and are essential tools in interactive systems for decision support and business operations for risk management. Yopougon is one of the municipalities in the district of Abidjan in Ivory Coast. Rapid and uncontrolled and unreliable urbanization make it more and more sensitive and vulnerable to floods which cause widespread damages loss of human life and water pollution. This causes damage to people whose socio-economic cost is particularly important that these events are violent and more frequent. It then becomes important to do research to assess sanitation network of Yopougon.
