Assessment of the Environmental Effects of 2012 Floods in Aguleri and Umuleri, Anambra East Local Government Area of Anambra State, Nigeria (Published)

The study assessed the effects of 2012 flood in Aguleri and Umuleri in Anambra East Local Government Area. In doing this, questionnaire was administered randomly to the residents. The data generated were analyzed using frequency/percentage tabulation and Mann-Whitney U-Test statistical technique. The following hypothesis was tested: there is no significant difference between the environmental effects of 2012 floods in the two communities. The results showed that there is no serious variation between the health, personal, social, economic and post effects of 2012 flood in the two communities. Furthermore it also showed that the 2012 flood caused serious social, economic, personal and post effects on the inhabitants of the area. Consequent upon the findings, the study recommended that there should be flood hazard mapping in order to ascertain areas prone to flooding, so as to reduce the occurrence of flood in the area. It further recommended that the river channels in the area be constantly dredged from time to time so as to increase their capacity for retaining water. Moreover, it recommended that the inhabitants of the area be enlightened on the causes and effects of flood. Finally, it recommended that environmental laws, especially those relating to flood occurrence and management, and land-use be enforced. In addition, areas of future research should be: (1) to ascertain the after-effect (post effect) of flooding on agriculture in the area; and (2) to obtain a flood hazard map for the entire Anambra State, especially the Anambra East Local Government Area, so as to know the areas prone to flooding, and to adopt adequate flood management techniques.

Flood Disaster: An Empirical Survey of Causative Factors and Preventive Measures in Kaduna, Nigeria (Published)

Flood is a water induced disaster that leads to temporary overflow of dry land and causes serious damage on lives, property, and infrastructures. Flood has created a lot of damaging effect in Nigeria, resulting to the death of people, collapse of buildings, destruction of properties, damage of agricultural produce, loss of land and increased government expenditure. Despite persistent occurrence of this disaster, there is limited research geared at studying the factors that cause flooding and measures to effectively control it. To fill this gap, a random survey was conducted on 40 households, community leaders and agencies responsible for the management of flood in Kaduna State, Nigeria. Relative Important Index (RII) was employed for ranking the factors and the preventive measures. From the result, the common factors that cause flooding were poorly constructed drainage, heavy rainfall and improper waste disposal. Preventive measures for flooding were proper dumping of refuse, awareness of the public on the need to adhere to environmental rules, empowerment of government agencies to monitor residential building construction, implementation of government policies on flood and sanitization of town/city planners. Increased awareness at all levels (community, local, state and federal) of the risk of flooding, appropriate response techniques in mitigating flooding via implementation of flood control policies and flood early warning system to control flooding in Nigeria were also recommended.
