Determining when and where flood strikes can be
a daunting task. Apart from heavy and prolonged rainfalls and
river overflows, there are anthropogenic causal factors of
flooding. These anthropogenic factors are significantly variable
and exacerbate floods, but may be difficult to measure.
This study aims to unravel some of the anthropogenic factors,
particularly with respect to their contributions to the flood in
Ibadan City on 26 August 2011. Data were collected through
structured questionnaire and key informant interviews. The
August 2011 Ibadan flood was perhaps the worst in the history
of this ancient city. Twelve anthropogenic factors are
broadly identified as having contributed to the flood and the
flood had five major consequences. Some policy implications
that can help prevent future flood occurrence are outlined.
