Flood Vulnerable Area Assessment of Abakaliki Metropolis South-eastern Nigeria.

As a result of global warming, the climate change in Africa and Asia is predictably becoming more variable, and weather events expected to go more frequently extreme and severe. This includes increasing risk of drought and flooding in new areas. Inundation by extreme floods events is recorded every year worldwide. The potential consequences are profound increasing risk, particularly on environment and people in the less developed countries. Flooding cannot be totally avoided and maybe their occurrence will increase due to climate change. Absolute protection is both unachievable and unsustainable because of high costs and inherent uncertainties. Abilities to mitigate and or prevent flood disasters, cope with and recuperate from the effects have not been sufficiently taken into account nor developed. Communities within watershed or along the River system such as Abakaliki metropolis are mostly under threat of constant flooding menace. When flooding strike, the poor and socio-economically disadvantaged suffer the most and are least equipped to cope with impacts. Vulnerability assessment which many regions of the world recently commenced becomes the way forward. Assessing vulnerability and impacts requires and analysis of information on climate elements, such as temperature, rainfall and non-climatic data, such as situation on the soil, altitude and other characteristics of elements-at-risks indicators. This informs for a well thought-out monitoring (risk assessment), mitigation, coping strategies and adaptation measures which can be adopted by all the vulnerable stakeholders including Governments at all tiers
