Interest in Indigenous Knowledge (IK) system has been particularly highlighted in
flood disasters, due to the likely increase of flood events resulting from
anthropogenic climate change through heavy precipitation, increased catchment
wetness, and sea level rise. Therefore, bringing IK of flood risk reduction into focus
and context to deepen the understanding of how people manage their own changing
circumstances can bring more pertinent information about flood risk reduction. This
paper reviews the significance of IK in flood risk reduction. Specifically, the paper
discusses IK flood forecasting, early warning signs, adaptation and coping strategies
in flood risk reduction around the world. The Methodological approach employed for
this paper is the review of existing literature on IK in flood Disaster Risk Reduction
(DRR), and then a summary of the outcomes of the studies reviewed was discussed.
However, it was deduced from the review undertaken, the need for an intensive
empirical study to be conducted to explore how efficient these strategies or
techniques are, in relation to flood risk reduction, which this paper strongly
recommends for further investigation. Additionally, the paper concludes by
emphasizing that although the IK of flood risk reduction is embedded in varied
regions around the globe, still there is a need for further study to be carried out in
order to unveil why the similarities and variations in flood risk reduction
practices/strategies between regions.
