E. Servat et al., REGARDING THE REDUCTION OF FLOW IN WESTER N AND CENTRAL-AFRICA, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 325(9), 1997, pp. 679-682
An important climatic fluctuation has now been observed for 25 years a
ll over Western and Central Africa. This fluctuation is translated by
a notable decrease in annual rainfall since the end of 1960s and the b
eginning of 1970s. This reduction of rainfall has serious consequences
on flow regimes within this region. This study has allowed the charac
terization of these changes and has interpreted them on a regional lev
el. It has also emphasized the very important decrease of the volume o
f flow in the rivers, which has economical and environmental results.
