Abstract The over-dependence of the
economic development process within sub-Saharan Africa on water calls for
detailed assessment of the probable impact of climate change on hydrology and
water resources within the region. This paper examines the effect of total
annual and decadal rainfall fluctuations on the hydrological regime within
Ogun-Oshun River Basin Development Authority (Nigeria).
Key words decadal rainfall analysis; rainfall
anomalies estimation; hydrological regime; water resources
