Since the late 1960s, Senegal suffered from the dramatic drought which affected all the Sahel of West Africa. Thirty years later, rainfall amounts well above the 1961-1990 average may announce the end of this period of aridity. Together with this rainfall increase, floods have been reported in most Senegalese cities in 1999, 2000 and 2001. Because of these floods, many affected areas have been abandoned and stricken population has to be rehoused in precarious conditions. Most analysts consider these floods as a new phenomenon, never observed before, and they are blamed on the exceptional heavy daily rainfall. Analysing the relationship between floods and rainfall events in 1999 et 2000, it appears that rainfall amounts responsible for the beginning of each flood are far to be exceptional. However, the vulnerability of the Senegalese cities facing the risk of flood seems to have increased as a result of urban mismanagement. [less ▲]

The Sahel is affected by a severe drought since the late 1960s. This paper analyses the potential fluctuations of wind on a 44-year period (1951-1994) on the Atlantic coast of West Africa. The change in wind direction could be a witness of a modification on a synoptic scale. The wind velocity recorded in four meteorological stations does not show any rise which could be linked with a continuous aridification. [less ▲]
