Assessment and Control Measures of Flood Risk in Ajibode Area of Ibadan, Oyo State, Nigeria

Abstract

Flood is one of the major factors that prevent Africa’s population from escaping poverty level. The most hit by flood are usually urban poor who have less choice, but to end up living in flood prone areas. Ravaging flood events in Nigeria can be dated back to 1963 in Ibadan city, when Ogunpa River was over-flown causing loss of lives and properties. Many factors have been attributed as the resultant factors leading to floods in literature. This study thus assesses flood risk and its control measures in Ajibode area of Ibadan, Oyo state, while appropriate recommendations are made in order to reduce flood risk in the study area. In order to achieve this, questionnaires were administered through random systematic sampling technique to the household heads of 216 buildings from 720 buildings as the sampling frame of the study. Chi-square test reveals significant relationships between annual house rent and monthly income of the respondents with their vulnerability to flood with p-values of 0.00 and 0.04 respectively.
