Gestion des inondations dans les villes de Ouagadougou et de Bobo-Dioulasso dans un contexte urbain – entre jeux d’acteurs et logiques territoriale


Download



This French-language report describes how Burkina Faso seeks to manage the problems of urban flooding in its two principal cities, Ouagadougou and Bobo-Dioulasso.  In September 2009, 263 millimetres of rain – over one-third of the average annual precipitation – fell in just 12 hours, causing loss of life and widespread damage. The lead author of this report Dr Assonsi Soma, who has become an expert on flood management in Burkina Faso, together with colleagues from the Universities of Ouagadougou and Bobo-Dioulasso, reviews the policies and actions of national and local government agencies struggling to meet the dimensions of the challenge in these urban centres with their fast-growing populations and many informal settlements in poor areas.

Based on this survey of the measures taken to-date and the gaps in decision-making that remain, the report makes recommendations for national leaders and city mayors to bring about better management of the risks of urban flood in Burkina Faso. Major rainfall events are lively to reoccur in the context of the increasing climatic variability affecting the country, as noted by the PRISE project.
